New Wifi Tech Can See Through Walls And Map The Inside Of A Building In “20 To 30 Seconds”
Most of us don’t pay much attention to the WiFi routers in our homes. It’s an innocuous technology that we all take for granted, and we don’t really think about unless it’s not working properly. However, WiFi has a unique property that might make …

Un amministratore sicuro di sé?

The process of globalization is continuing rapidly and many corporate organizations both big and small have their production facilities or branch offices at different places. In order to access to secure information and application, increase productivity and business continuity working from remote locations, they need improved resource sharing and faster communication applications. As part of their strategic methods, many of these companies are widely using appliances known as Wide Area Networking (WAN) optimization devices to meet their business requirements.
If the transactions or downloads take a lot of time, the mobile employees cannot give prompt service to the customers. So it is very important to optimize data streams and eliminate unnecessary transfers in the network. In order to eliminate the network problems and optimize throughput, companies should prioritize the mission-critical applications to help the remote employees to access the network applications at faster rate.
The application performance is directly related to revenue protection and growth, and customer satisfaction and of course a quick return on investment. Application Performance Management (APM) is a solution for enhancing performance within a network. It maintains and monitors transmission quality at an acceptable level. It also enhances application response times by eliminating excess and unnecessary data transfer.
Application performance management is all about enhancing user’s experience with application availability and quick response time enabling them to provide good customer service. Today a majority of the companies recognize the importance of the APM and its impact on the productivity and return on investment. According to a survey conducted by IDG Research, 90 percent of the respondents of the survey believe the adoption of an APM solution will create an effective process for detecting and resolving performance issues in their network.
It monitors and performs at:
APM measures, manages, and optimizes the performance and service availability of software applications in a WAN. It monitors and manages the ongoing application 24×7 and provides a detailed breakdown of response time and its effects on server, network, application and end user levels.
* Server level
An Application Performance Management solution captures data flow pattern of each important transaction. APM also forecasts response times when the data centers are consolidated.
* Network level
At network level, it reduces risks to application performance and optimizes bandwidth capacity. It provides insight into the WAN application traffic patterns of the company. It identifies the top applications based on bandwidth usage, packet losses and failed TCP connections, if any.
* Application level
At application level, the APM monitors and manages new application rollouts, determines the root cause of slow response time for a mission critical application and captures data flow pattern of each important transaction.
* End-user level
The user’s experience with an application is very important. Application availability and response time are the main performance functions that end users look for. They should be sufficiently satisfied with application interactions to remain productive. APM at the end user level monitors and manages the baseline current user response times for the critical applications.
The main goal of APM best practices is to improve the performance outcome by effective application performance management optimization. Some of the best practices by an APM method are:
The APM process begins by understanding the user and application needs. Understanding what is important and how to measure the performance of the applications is the critical aspect of APM method. It comprises a comprehensive analysis of performance with respect to applications, network infrastructure and business processes of the organization.
Then it measures data, which includes the resources used by the application and the response time of applications from the perspective of the end user. Measuring these things provides a useful tool to assess how well the systems are doing. Performance metrics are measured both in real time and over defined periods using APM solution. It delivers continuous monitoring of and reporting for the entire infrastructure.
By understanding and measuring the application performance, IT managers can immediately determine who is experiencing performance problems and communicate with them. They can determine with what applications the end user is facing problems and pinpoint the causes. Errors are detected in quick time minimizing risks and protecting infrastructure from failure.
* Link to business
APM determines the root cause of slow response time for a mission critical application, fine tunes the protocol to overcome inefficiencies and provides solutions to remedy performance issues. APM solution determines importance and measures performance, and then links performance to business requirements to provide great end user experience.
Since the productivity of any company depends heavily on the performance of software accessed, one should be very careful while choosing an APM solution. Even small delays can lead to considerable amounts of wasted time, which leads to end user dissatisfaction. So, let a reputed company take care of all your Application Performance Management (APM) needs. Remember, faster response times means the users get their responses quicker, work faster, which in turn increases your company’s revenue.
The two most popular books on the Junos OS are now combined, revised, and updated into one book!
It’s day one and you have a job to do, so start using the Junos CLI. It’s fast, it’s easy, and you’re just a few hours away from modifying, saving, and loading configuration files onto your device.
NOTE This book was originally published as two books, Day One: Exploring the Junos CLI and Day One: Configuring Junos Basics. It has been updated, revised, and technically reviewed to match the current Junos OS operations.
The Junos OS command-line interface (CLI) includes dozens of shortcuts to get things done in your network. You’ll spend much less time pounding away on your keyboard once you master these commands, and soon, with just a little effort, you’ll learn why so many people say that the Junos OS saves time (often lots of it), reduces repetitive tasks, and helps to avoid costly mistakes.
Day One: Exploring the Junos CLI, Second Edition is for beginning users of devices running the Junos OS, or as a refresher course when it’s time to scale Juniper technology. It not only lays the foundation for learning the Junos OS, but also facilitates understanding of the more advanced Junos OS books that populate the Day One library.
This Second Edition combines two previous best-selling Day One books into an updated and revised tutorial that will get you started and then help you get things done.
IT’S DAY ONE AND YOU HAVE A JOB TO DO, SO LEARN HOW TO:
• Navigate the CLI’s operational mode and configuration mode.
• Understand the hierarchies that underlie each mode.
• Get onboard help and use keyboard shortcuts to speed up your work.
• Show device status, alarms, and other helpful information in the Junos OS operational mode.
• Modify, save, and load configuration files with minimal risk to operations.
• Use basic configuration mode commands such as show, set, and delete.
• Capitalize on the safety features of the Junos OS commit model.
• Prepare system changes in advance.
• Use the shortcuts and tips of experienced users and avoid common problems.
