Hi folks. Does anyone know the time it takes or should take for an SVC to be rerouted in a small 4-6 switch ATM network running PNNI ? Is it part of the ATM spec or does it depend on the switch manufacturer ?

That depends on if the SVC was torn down due to a broken link, or if the switch is just coming online, or if it was rerouted around congestion, and a million other tuneable factors. In our network, SVC (SPVCs) get rerouted at near sonet speeds, although that's not very scientific. Dan. On Tuesday 30 November 2004 16:25, Paul Khavkine wrote:

In a situation where a link fails and the VC needs to be rerouted. The VC path has allready been setup. Thanx Paul On Tue, 30 Nov 2004, Dan Armstrong wrote:

In the network I work with, SVC re-routes are near instantaneous... If I break a link on purpose, I'm hard pressed to type in the command fast enough to see if the svc is back up and it's already re-routed... 4-6 switches should be the same.. What kind of switches are we talking about here?
