IPSec gateway is not the first generation of scalability or performance as designed, therefore, use the basic functions of personal computers and small-scale simulation tests have been sufficient. However, with the expansion of testing, performance testing using a personal computer has become not only difficult to manage, and costly. Another test method is to have two IPSec gateways back to back, and are used on each side of the business of the load generator. This method also has many shortcomings. Use back to back set or a PC-based test is difficult to accurately measure the delay time, particularly in relation to each tunnel, timing information at each stage of the test even more so. Back to back test and not the other IPSec gateway that synergy may exist or timing issues.
The General Assembly in last years WinHEC, Microsoft vice president Bill Laing talking about Windows Server 2008 R2, is put behind him the great IBM and HP servers. Microsoft TechEd event participants not only hear the introduction of Office 2010 will also be the first to try this new software. Microsoft said in July the new version of Office to launch a limited technology preview program eligibility, and the Microsoft conference this week in Los Angeles who will be the first to try this latest flagship product.
