Meeting today’s business requirements on the network presents several challenges,
particularly when you consider the number of different analyses, performance and security tools that may need access to the same data stream. Furthermore, in many cases each toolset is managed by different individuals or groups. Each group has its own requirements and concern and its own dedicated tools designed to deliver the information it is mandated to provide. To complicate matters further, each tool may need a slightly different form or portion of the same traffic; in the case of servers, for example, one group might want to see web threads, while another group needs to see overall web application performance. Complex rules and specific network designs must be created to ensure that traffic flows are properly articulated and understood for each tool.
