Discovery of Network Resources for Better Quality of Service

Knowledge of physical topology of an Internet Protocol (IP) network is very important to a number of critical network management tasks like reactive-proactive resource management, event correlation and root cause analysis. Thus automatically discovering the physical topology is necessary. The present work is mainly concentrated on discovering Physical Topology (ie, layer 2) as well as layer 3 topology in heterogeneous IP networks. This mainly relies on Simple Network Management Protocol Management Information Base (SNMPMIB) information that is widely supported by IP networks and requires no modifications to the operating system software running on elements or hosts
