A Data Access Network is a "Data Socket" for monitoring tools; adds, changes and moves can be executed at anytime without physical changes to the production network. Aggregation and multicasting allow consolidation of expensive tools and sharing of SPAN ports and taps. Speed changes and media conversion are easily accommodated.
Network traffic can be "mapped" using multi-rule filters such that data aggregated from multiple switches or taps can be redistributed to multiple load-sharing monitoring tools, with each tool analyzing a specific VLAN range, port number or IP subnet, thereby performing comprehensive monitoring without oversubscribing any single tool.
Data Access Network (DAN) is a revolutionary concept whose time has come. It is the "intermediation" gateway between the network and the tools, allowing distributed connectivity and flexible load balancing between the monitoring requirement of the production network and resources available from the mission critical monitoring tools.
