Tradeshow Event WIFI Strategies


It’s the 21st Century. Sure, we may not have flying cars or robot servants secretly plotting the demise of human civilization, but we do rely on WIFI to get things done. Work, home, entertainment, education… We’re a wired culture and the internet is our constant connection to everything and everyone.

Given that social media apps, such as Twitter and Facebook, as well as good old email, are easy and instant ways to stay in touch with a consumer network, it only makes sense that you would want to utilize reliable internet access when presenting to potential clients at a trade show. Or, maybe you have a snazzy website, something you paid good money to put on the web, and you’d like your clients to know just how fun and easily navigable it is.

The problem is, those fellows over there who run the main gig? They’re well aware of this reliance on broadband web access. They’re going to charge for it and they’re not going to be shy about pricing, because they know just how badly you need to be connected.

So, what if you don’t want to pay, or worse, can’t afford the ballpark of eight hundred and fifty bucks a day to be plugged in? It’s no secret that it’s a tough economy out there. Sure, your smart phone might personally keep you in contact with your client network and if you’re feeling super inventive maybe you can project directly from your laptop or iPad. But, let’s be real, this is a trade show, not a frat party showcase of hilarious YouTube video. You need a strong, fast, reliable connection.

Solution? Bring your own internet to the party. Rent a trade show internet kit from smartsourcerentals.com.

At a fraction of what you’d pay for internet directly provided by the trade show itself, consider renting an “Internet-in-a-Box” kit. It’s secure, it’s easily set up in minutes, and requires no downloads, installation, or programming. In no time, you’ll be set up and updating your status without having handed over loads of cash. You’re in control of your connection, with no concerns about usage limits and, with a secure password protection, there’s no worry about the other booths sucking up your bandwidth.

Take control, get yourself online, and impress potential clients with the razzle-dazzle of your own dedicated web connection.

CCNA ? CCNP Training ? IPv6 Addressing


As a CCNA / CCNP candidate you are expected to understand IPv6

During your career as a Cisco network engineer you will have to deal understanding IPv6 address structure.

For your CCNA and CCNP studies you have to at some point confront and understand IPv6. At first glance it can see quite daunting compared to IPv4 that we are all used to, in actual fact IPv6 is quite a simply addressing protocol once you get past the initial shock. In this article we are going to have a look at Neighbour discovery protocol for layer 2 mapping.

When an IPv6 host or router needs to send a packet to some other host on the same network it will first of all look into it’s own local neighbour database to find if it has an IPv6 to MAC mapping, if it finds the right mapping the host will use it, if there is no mapping the host will need to resolve the known layer 3 IPv6 address to a currently unknown Layer 2 MAC address and to do this the host uses the Neighbor Discovery Protocol or NDP to discover the MAC address dynamically.

The Sending host will use a multicast message called a Neighbor Solicitation (NS) icmp message to ask the receiving host for it’s MAC address, the receiving host will reply with a Neighbor Advertisement (NA) icmp message unicast in return with the requested MAC address.

How IPv6 achieves this is all in the construction of the Neighbor Solicitation message which makes use of a special IPv6 destination address called a “Solicited Node Multicast”, this solicited Node Multicast at any given moment represented all of the IPv6 hosts on the link, the last 24 bits of the Solicited Node Address are the last 24 bits of the IPv6 address of the device that a host is requesting the MAC from.

The IPv6 multicast destination address is FF02::1:FF:0/104 the final 24 bits are made up of the last 24 bits of the IPv6 address to which the message is being sent to. For example if a host wanted to discover the MAC address of an IPv6 host addressed as 2222:3333:4444:5555:6666:AAAA:BBBB:CCCC:DDDD/64 then the solicited Node Address will look like the following FF02::1:FF:CC:DDDD/104

When a sending hosts wants to get the MAC address from the IPv6 host of 2222:3333:4444:5555:6666:AAAA:BBBB:CCCC:DDDD/64 it will take the last 24 bits of the known IPv6 address and place them into the remaining 24 bits of the Solicited Node Address and since all IPv6 hosts listen to their own Solicited Node addresses, when they hear their address they will reply with the MAC address.

    Reproduced from Wikipedia, the free encyclopedia
    en.wikipedia.org/wiki/Amsterdam
    Amsterdam is the capital and largest city of the Netherlands, located in the province of North Holland in the west of the country. The city, which had a population of 747,290 on 1 January 2008, comprises the northern part of the Randstad, the 6th-largest metropolitan area in Europe, with a population of around 6.7 million.

    Its name is derived from Amstel dam,[7] indicative of the city’s origin: a dam in the river Amstel where the Dam Square is today. Settled as a small fishing village in the late 12th century, Amsterdam became one of the most important ports in the world during the Dutch Golden Age, a result of its innovative developments in trade. During this time, the city was the leading centre for finance and diamonds.[8] In the 19th and 20th centuries, the city expanded and many new neighbourhoods and suburbs were formed.

    The city is the financial and cultural capital of the Netherlands. Many large Dutch institutions have their headquarters there, and 7 of the world’s top 500 companies, including Philips and ING, are based in the city [9]. The Amsterdam Stock Exchange, part of Euronext, is located in the city centre. Amsterdam’s main attractions, including its historic canals, the Rijksmuseum, the Van Gogh Museum, Anne Frank House, its red-light district and its many cannabis coffee shops, draw 4.2 million tourists annually.[10]

    The earliest recorded use of the name "Amsterdam" is from a certificate dated 27 October 1275, when the inhabitants, who had built a bridge with a dam across the Amstel, were exempted from paying a bridge toll by Count Floris V.[11] The certificate describes the inhabitants as homines manentes apud Amestelledamme (people living near Amestelledamme). By 1327, the name had developed into Aemsterdam.[11] A local romance account[clarify] has the city being founded by two fishermen, who landed on the shores of the Amstel in a small boat with their dog.[citation needed] Amsterdam’s founding is relatively recent compared with much older Dutch cities such as Nijmegen, Rotterdam, and Utrecht. In october 2008 historical geographer Chris de Bont suggested that the land around Amsterdam was being reclaimed as early as the late 10th century. This does not necessarily mean there was already a settlement then. This was however not necessarily the reclaiming of the land for farming – it may also have been just for the peat (for fuel).

    But Amsterdam city archeologist Jerzy Gawronski argues that the pre-city settlement of craftsmen in 1200 "didn’t come falling from the sky". [12]

    Amsterdam was granted city rights in either 1300 or 1306.[13] From the 14th century on, Amsterdam flourished, largely because of trade with the Hanseatic League. In 1345, an alleged Eucharistic miracle in the Kalverstraat rendered the city an important place of pilgrimage until the alteration to the protestant faith. The Stille Omgang—a silent procession in civil attire—is today a remnant of the rich pilgrimage history.[14]

    In the 16th century, the Dutch rebelled against Philip II of Spain and his successors. The main reasons for the uprise were the imposition of new taxes, the tenth penny, and the religious persecution of Protestantism by the Spanish Inquisition. The revolt escalated into the Eighty Years’ War, which ultimately led to Dutch independence.[15] Strongly pushed by Dutch Revolt leader William the Silent, the Dutch Republic became known for its relative religious tolerance. Jews from the Iberian Peninsula, Huguenots from France, prosperous merchants and printers from Flanders, and economic and religious refugees from the Spanish-controlled parts of the Low Countries found safety in Amsterdam. The influx of Flemish printers and the city’s intellectual tolerance made Amsterdam a centre for the European free press.[16]

    The 17th century is considered Amsterdam’s Golden Age, when it became one of the wealthiest cities in the world. Ships sailed from Amsterdam to the Baltic Sea, North America, and Africa, as well as present-day Indonesia, India, Sri Lanka and Brazil, forming the basis of a worldwide trading network. Amsterdam’s merchants had the largest share in both the VOC (Dutch East India Company) and the WIC (Dutch West India Company). These companies acquired overseas possessions that later became Dutch colonies. Amsterdam was Europe’s most important point for the shipment of goods and was the leading financial centre of the world. In 1602, the Amsterdam office of the VOC became the world’s first stock exchange by trading in its own shares.[17]

    Amsterdam’s prosperity declined during the 18th and early-19th centuries. The wars of the Dutch Republic with England and France took their toll on Amsterdam. During the Napoleonic Wars, Amsterdam’s fortunes reached their lowest point. However, the later establishment of the United Kingdom of the Netherlands in 1815 marked a turning point. New developments, by people such as city planner Samuel Sarphati, drew their inspiration from Paris

    The end of the 19th century is sometimes called Amsterdam’s second Golden Age.[18] New museums, a train station, and the Concertgebouw were built, while during this time, the Industrial Revolution reached the city. The Amsterdam-Rhine Canal was dug to give Amsterdam a direct connection to the Rhine, and the North Sea Canal was dug to give the port a shorter connection to the North Sea. Both projects dramatically improved commerce with the rest of Europe and the world. In 1906, Joseph Conrad gave a brief description of Amsterdam as seen from the seaside, in The Mirror of the Sea. Shortly before World War I, the city began expanding, and new suburbs were built. Even though the Netherlands remained neutral in this war, Amsterdam suffered a food shortage, and heating fuel became scarce. The shortages sparked riots in which several people were killed. These riots are known as the Aardappeloproer (Potato rebellion). People started looting stores and warehouses in order to get supplies, mainly food. [19]

    Germany invaded the Netherlands on 10 May 1940 and took control of the country after five days of fighting. The Germans installed a Nazi civilian government in Amsterdam that cooperated with the persecution of Jews. Some Amsterdam citizens sheltered Jews, thereby exposing themselves and their families to the high risk of being imprisoned or sent to concentration camps. More than 100,000 Dutch Jews were deported to concentration camps. Perhaps the most-famous deportee was the young German girl Anne Frank, who died in the Bergen-Belsen concentration camp.[20] Only 5,000 Dutch Jews survived the war. At the end of World War II, communication with the rest of the country broke down, and food and fuel became scarce. Many citizens traveled to the countryside to forage. Dogs, cats, raw sugar beets, and Tulip bulbs—cooked to a pulp—were consumed to stay alive.[21] Most of the trees in Amsterdam were cut down for fuel, and all the wood was taken from the apartments of deported Jews. After the war, approximately 120,000 Dutch were prosecuted for their collaboration with the Nazis.

    Many new suburbs, such as Osdorp, Slotervaart, Slotermeer, and Geuzenveld, were built in the years following World War II.[22] These suburbs contained many public parks and wide, open spaces, and the new buildings provided improved housing conditions with larger and brighter rooms, gardens, and balconies. Because of the war and other incidents of the 20th century, almost the entire city centre had fallen into disrepair. As society was changing, politicians and other influential figures made plans to redesign large parts of it. There was an increasing demand for office buildings and new roads as the automobile became available to most common people.[23] A metro started operating between the new suburb of Bijlmer and the centre of Amsterdam. Further plans were to build a new highway above the metro to connect the central station and city centre with other parts of the city.

    The incorporated large-scale demolitions began in Amsterdam’s formerly Jewish neighbourhood. Smaller streets, such as the Jodenbreestraat, were widened and saw almost all of their houses demolished. During the destruction’s peak, the Nieuwmarktrellen (Nieuwmarkt riots) broke out,[24] where people expressed their fury about the demolition caused by the restructuring of the city. As a result, the demolition was stopped and the highway was never built, with only the metro being finished. Only a few streets remained widened. The destroyed buildings were replaced by new ones corresponding to the medieval street plan of the neighbourhood. The new city hall was built on the almost completely demolished Waterlooplein. Meanwhile, large private organisations, such as Stadsherstel Amsterdam, were founded with the aim to restore the entire city centre. Although the success of this struggle is visible today, efforts for further restoration are still ongoing.[23] The entire city centre has reattained its former splendor and—as a whole—is now a protected area. Many of its buildings have become monuments, and plans exist to make the Grachtengordel (Herengracht, Keizersgracht, and Prinsengracht) a Unesco World Heritage site.[25]

    Being part of the province North-Holland, Amsterdam is located in the northwest of the Netherlands next to the provinces Utrecht and Flevoland. The river Amstel terminates in the city center into a large number of canals that eventually terminate in the IJ. Amsterdam is situated 2 meters above sea level.[4] The surrounding land is flat as it is formed of large polders. To the southwest of the city lies a man-made forest called het Amsterdamse Bos. Amsterdam is connected to the North Sea through the long North Sea Canal.

    Amsterdam is intensely urbanized, as is the urban area surrounding the city. Comprising 219.4 square kilometers of land, the city proper has a population density of 4457 inhabitants and 2275 houses per square kilometer.[26] Parks and nature reserves make up 12% of Amsterdam’s land area.[27]

    Amsterdam enjoys a temperate climate, strongly influenced by its proximity to the North Sea to the west with prevailing north-western winds and gales. Winter temperatures are mild, seldom below 0°C. Frosts merely occur during spells of eastern or northeastern winds from the inner European continent, i.e., from Scandinavia, Russia, and even Siberia. Summers are warm but rarely hot. Days with measurable precipitation are common. Nevertheless, Amsterdam’s average annual precipitation is less than 760 mm. Most of this precipitation is protracted drizzle or light rain, making cloudy and damp days common during the cooler months, October through March. Only the occasional Western storm may bring a lot of water at once, requiring all of it to be pumped out to higher grounds or to the seas around the city.

    Amsterdam fans out south from the Amsterdam Centraal railway station. The Damrak is the main street and leads into the street Rokin. The oldest area of the town is known as de Wallen (the quays, this does not refer to the old city walls, the Dutch word for wall being ‘muur’). It lies to the east of Damrak and contains the city’s famous red light district. To the south of de Wallen is the old Jewish quarter of Waterlooplein. The 17th century girdle of concentric canals, known as the Grachtengordel, embraces the heart of the city.

    Beyond the Grachtengordel are the formerly working class areas of Jordaan and de Pijp. The Museumplein with the city’s major museums, the Vondelpark, a 19th century park named after the Dutch writer Joost van den Vondel, and the Plantage neighborhood, with the zoo, are also located outside the Grachtengordel.Several parts of the city and the surrounding urban area are polders. This can be recognized by the suffix -meer which means lake, as in Aalsmeer, Bijlmermeer, Haarlemmermeer, and Watergraafsmeer.

    The Amsterdam canal system is the result of conscious city planning.[29] In the early 17th century—when immigration was at a height—a comprehensive plan was developed that was based on four concentric half-circles of canals with their ends resting on the IJ bay.

    Known as the Grachtengordel, three of the canals are mostly for residential development: Those are the Herengracht (Gentleman’s Canal), Keizersgracht (Emperor’s Canal), and Prinsengracht (Princes Canal’). The fourth and most outer canal, the Singelgracht (not to be confused with the older Singel), served purposes of defense and water management.

    The defensive purpose was established by moat and earthen dikes, with gates at transit points, but otherwise no masonry superstructures.[30] Furthermore, the plan envisaged: (1) Interconnecting canals along radii; (2) creating a set of parallel canals in the Jordaan quarter, primarily for transportation purposes; (3) converting the defensive purpose of the Singel to a residential and commercial purpose; (4) constructing more than one hundred bridges. Construction started in 1613 and proceeded from west to east, across the breadth of the lay–out, like a gigantic windshield wiper as the historian Geert Mak calls it—and not from the centre outwards as a popular myth has it. The canal constructions in the southern sector were accomplished by 1656. Subsequently, the construction of residential buildings commenced slowly. The eastern part of the concentric canal plan, covering the area between the Amstel river and the IJ bay, has never been implemented. In the following centuries, the land was used for parks, old people homes, theaters, other public facilities, and waterways without much planning. [31]

    Over the years, several canals have been filled in becoming streets or squares, such as the Nieuwezijds Voorburgwal and the Spui

    Defining Software Defined: An Intro to the Software Defined WAN


    Defining Software Defined: An Intro to the Software Defined WAN

    A chalk talk video with John Dickey, Talari Co-Founder & CTO

    The right Software Defined WAN (SD-WAN) can proactively manage network capacity, quality, and performance. Discover Talari’s definition of a smart SD-WAN including the architecture, centralized management capabilities, distributed client intelligence and most importantly—smart application and user-driven policies.

    Video Transcriptions:

    There is a lot of talk about Software Defined WANs, but honestly, even more confusion. Many people have different perspectives and biases on what a SD-WAN is, and more importantly, what problems it actually solves.

    A little background. Talari has been delivering SD-­‐WAN solutions since 2007.

    We have hundreds of customers and many have been in production for over 5 years.

    We are the innovator and proof-case for SD‐WANs.

    Let’s look at some of the key requirements, from our perspective of what a SD‐WAN solution is.

    Our list is rather long, so let’s simplify it.

    We’ll start with drawing a SD-WAN network. In the center there is a SD‐WAN Controller with an Administration console which may be located at the enterprise or in the cloud data center.

    Remote to the SD-WAN controller at the branch offices or maybe even the cloud, are the SD-WAN client nodes that are either physical or virtual machines.

    Lastly, there are applications and end-users.

    Now that we have shown you ‘what’ an SD-WAN looks like, let’s discuss what is needed to be a Smart SD-WAN.

    First, it needs a centralized Smart SD-WAN controller and it needs to have an administrative console. Second, it requires distributed Smart SD-WAN clients. Third the SD WAN needs to be application and user driven.

    Now let’s go a little deeper. First the SD-WAN controller must learn from the SD-WAN clients about their local networks and then the controller must teach the SD-WAN clients about the global network. Information that is shared and synchronized includes time, topology, policy, and software versions.

    Peered with the controller should be a SD-WAN management element that provides assessment and analysis to the application’s network behaviors, for use in strategic decision making for the network.

    Can you imagine trying to configure a complex hybrid network per hop using a command line interface? Neither can we, so a centralized high level management tool is necessary.

    The solution needs to be seamlessly adaptive therefore it requires a high amount of constant synchronization to enable it to adjust rapidly to changes in the networks and the applications.

    Second, the Software Defined WAN clients must be fully software programmable and require minimal effort to install, but at the same time they need to be very capable of thinking on their feet.

    They must be able to utilize and assess multiple WANs simultaneously to create a hybrid of both public and private networks. Furthermore, they must provide real-time updates to each other of the current conditions of the network and applications.

    Smart SD-WAN clients need to be able to assess latency, jitter, and loss for every packet as it travels the network in each direction—because round-trip data is not very useful in assessing applications behavior.

    Lastly, SD‐WAN Clients must provide for first and last mile bandwidth reservation so as to prevent congestion.

    Most importantly, it’s all about the applications and the users.

    The SD‐WAN needs to direct application sessions to the most capable network for that traffic’s needs.

    For example, voice traffic should be directed to the network with the lowest latency.

    On the other hand, if a single applications session requires more bandwidth than a single network can provide, the application session should be able to utilize the entire capacity of all the aggregate networks without any out-of-order packets or end-user impacts.

    That’s just a taste of the some of the ingredients required in a SMART SD-WAN Solution.
    Talari has been delivering on the promise of SD-WANs longer than anybody else. Reach out to us at Talari and we’ll share more.
