Crossmatrix provides complete Network validation which virtually eliminates performance failures that would otherwise be discovered by actual users in the course of normal business operations. The enhanced LAN validation tests are made up of the expanded Service Performance Tool and the improved Ethernet Performance Tests suite. We use EtherScopeand Network Analyser to identify and correct problems within LAN. Validating LANs and proactively resolving problems with the EtherScope Network Assistant is more cost-effective than reacting to user complaints and troubleshooting a live, production network. We carry out to test the performance of DHCP, DNS, email, FTP, NT file, web and WINS servers. The user can apply custom, service-specific pass/fail limits to each test for quick and easy analysis. We provide owners, and maintainers with superior vision, combining speed, accuracy, and ease of use to optimize network performance.
