Development of Router Clusters to Provide Fast Failover in IP Networks
نویسندگان
چکیده
Vol. 9 No. 3 1997 A DIGITAL router engineering team has refined and extended routing protocols to guarantee a five-second maximum loss-of-service time during a single failure in an Internet Protocol (IP) network. We use the term router cluster to describe our improved implementation. A router cluster is defined as a group of routers on the same local area network (LAN), providing mutual backup. Router clusters have been in service since mid-1995.

Local Fast Failover Routing With Low Stretch
Network failures are frequent and disruptive, and can significantly reduce the throughput even in highly connected and regular networks such as datacenters. While many modern networks support some kind of local fast failover to quickly reroute flows encountering link failures to new paths, employing such mechanisms is known to be non-trivial, as conditional failover rules can only depend on loc...

متن کاملImpact of Traffic Load on SCTP Failovers in SIGTRAN
With Voice over IP (VoIP) emerging as a viable alternative to the traditional circuit-switched telephony, it is vital that the two are able to intercommunicate. To this end, the IETF Signaling Transport (SIGTRAN) group has defined an architecture for seamless transportation of SS7 signaling traffic between a VoIP network and a traditional telecom network. However, at present, it is unclear if t...
متن کاملThe Wackamole Approach to Fault Tolerant Networks Demo
Maintaining the availability of critical network servers is an important concern for many organizations. Server redundancy is the traditional approach to provide availability in the presence of failures. From the client perspective, a network-accessible service is resolved via a set of public IP addresses specified for this service. Therefore, the continued availability of a service via these I...
