ACADEMIC PROJECTS

Link state and Distance Vector Routing Protocols: Nov-2007

• To find the differences in convergence time of link state and distance vector routing protocols.
• A large network with redundant paths using OPNET is designed.
• Observed the impact of a failure link on convergence time.

Performance Analysis of Multicast Routing Protocols QOS using fuzzy Priority Scheduler: Dec-2007

• To increase the throughput and reduces the end-to-end delay in Ad Hoc networks, the QOS is measured using fuzzy priority scheduler.
• These inputs (D), (E), (Q) and output priority index (P) compared with different multicast routing protocols like ODMRP, CAMP and NTPMR.

Analysis of BGP Path Selection: April-2008

• Designed a small BGP network with two autonomous systems (AS).
• Initiated IBGP sessions with in autonomous system and EBGP session between the autonomous systems.
• Checked how these path attributes like Weight, Local preference and MED helps in best path selection criteria.

Emergency call handling in VOIP: Aug-2008

• As there are many issues in handling emergency calls like (911) in VOIP network.
• Major issues are Delay in placing the call, Locating the caller (i.e , Physical location) and Prioritizing emergency calls.
• Goal is to route the emergency call with minimum delay.
