Packet Handling Scheduling in Multiple Routing Configurations for Fast Ip Network Recovery
نویسندگان
چکیده
As a promising approach to improve network reliability, Proactive Failure Recovery (PFR) [1] reroutes failure affected traffic to backup paths without waiting for the completion of IP routing convergence. However, the failure affected traffic may cause congestion. If a proper scheduling policing mechanism is not used when a router redirect the traffic to alternative paths an overflow of packets may occur and degrade the performance. Therefore for reliability and from congestion free here we proposed a new scheme called WFQ [2] mechanism which regulates the packets using different classes and makes the packet transmission without any loss in a packet. Key Terms: Computer network reliability; Class-Based Queuing(CBQ); failure recovery; FIFO; Fair Queuing(FQ); protection; Quality of service(QOS); routing; Traffic Engineering; Weighted Fair Queuing(WFQ)

متن کاملProtected Packet Routing: Achieving Fast Failure Recovery in the IP Layer
Failure recovery in IP networks has gained much attention from both academic and industrial circles. The main challenge of this issue is how to achieve fast recovery while keep the implementation complexity and resource requirement at low level. Current IP networks rely on either routing table recalculation or lower layer protection for failure recovery. Although resource-efficient, routing rec...
متن کاملA Comparison between Two Post-Failure Load Distribution Techniques with Multiple Routing Configurations
When a link fails in an IP network, the network re-converges to redirect the traffic away from the failed link. IP fast reroute is used to minimize the time taken to redirect the traffic to an alternate path. Multiple routing configurations (MRC) is the IP fast reroute scheme under consideration. In this paper, we will discuss how to minimize the impact of the MRC recovery process on the post f...
