Nonstop Forwarding

In a control plane failure or a forced switchover event, the router continues to forward packets 
using the existing stale forwarding information. Nonstop forwarding requires clean control plane 
and data plane separation. Usually the forwarding information is distributed to the XCMs/XMAs.

Nonstop forwarding is used to notify peer routers to continue forwarding and receiving packets, 
even if the route processor (control plane) is not working or is in a switch-over state. Nonstop 
forwarding requires clean control plane and data plane separation and usually the forwarding 
information is distributed to the line cards. This method of availability has both advantages and 
disadvantages. Nonstop forwarding continues to forward packets using the existing stale 
forwarding information during a failure. This may cause routing loops and black holes, and also 
requires that surrounding routers adhere to separate extension standards for each protocol. Every 
router vendor must support protocol extensions for interoperability. 

Nonstop Routing (NSR)

With NSR on the 7950 XRS-Series routers devices, routing neighbors are unaware of a routing 
process fault. If a fault occurs, a reliable and deterministic activity switch to the inactive control 
complex occurs such that routing topology and reachability are not affected, even in the presence 
of routing updates. NSR achieves high availability through parallelization by maintaining up to 
date routing state information, at all times, on the standby route processor. This capability is 
achieved independently of protocols or protocol extensions, providing a more robust solution than 
graceful restart protocols between network routers.

The NSR implementation on the 7950 XRS-Seriesrouters supports all routing protocols. NSR 
makes it possible to keep the existing sessions (BGP,LDP, OSPF, etc.) during a CPM switchover, 
including support for MPLS signaling protocols. Peers will not see any change. 

Protocol extensions are not required. There are no interoperability issues and there is no need to 
define protocol extensions for every protocol. Unlike nonstop forwarding and graceful restart, the 
forwarding information in NSR is always up to date, which eliminates possible blackholes or 
forwarding loops.

Traditionally, addressing high availability issues have been patched through non-stop forwarding 
solutions. With the implementation of NSR, these limitations are overcome by delivering an 
intelligent hitless failover solution. This enables a carrier-class foundation for transparent 
networks, required to support business IP services backed by stringent SLAs. This level of high 
availability poses a major issue for conventional routers whose architectural design limits or 
prevents them from implementing NSR.
