Answer to Question #272567 in C++ for kalpana T

Question #272567

In the Virtual Circuit (VC) Subnet (refer the course material “Session 20 Network Layer Functionalities” in Moodle) every circuit will have a VC ID and the routing table includes the VC IDs to manage the circuits. But, the problem with VC ID is it is local to the system; VC IDs are assigned by the host system itself without the knowledge of VC IDs assigned by the other hosts. Because of which there will be a clash of VC IDs at the router. Understanding the ambiguity, the router then changes one of the VC IDs to a unique ID at router level and proceeds with data transfer (refer Slide No. 12 of the course material). Over and above the data transfer, this is the additional responsibility for a router which creates hiccups in the data communication. Question: Design a network system where VC IDs will be assigned uniquely which avoids VC ID collision at routers. Since such a system avoids the VC ID collision at the router, it should definitely save router's time and should improve performance of router.
