Chapter 5. BGP Performance
Networks are getting faster. The size and speed of links used in networks is increasing rapidly, and routers and switches move packets at rates that would have been unthinkable in the not to distant past. Routing protocols are no exception to this general trend, with OSPF, IS-IS, and EIGRP all boasting of subsecond convergence in many large networks.
How does BGP fit in? BGP is often perceived as a slow but robust protocol, giving up its speed for stability, commonly measuring convergence times in minutes rather than seconds. But is the BGP protocol really slow, or has little work been done in this area because everyone assumes it's slow?
While BGP may never converge in large internetworks in the subsecond range, BGP ...
