Multi-Segment Network Analysis
Most network analyzers are designed to provide information about a single network at a time. However, some of the latest software-based network analyzers can provide analysis from multiple links simultaneously. If this feature is supported in your analyzer, it can provide a method of watching the connections into and out-of a router or switch.
Since this kind of multi-segment analyzer uses a single clock source, precise packet timings can be compared across traces taken from different networks. This can be very helpful in determining router latency, since a WAN link and a LAN link can be captured simultaneously. Multi-tiered applications using multiple network links can be examined to determine exact latency time in a server.
Not all analyzers support data capture across multiple cards simultaneously. Check with your analyzer manufacturer to determine the capabilities and resource requirements for your analyzer!
