Seamless IGP Migrations

lvanbeve — Mon, 30 May 2011 12:57:54 +0000

Network-wide migrations of a running network, such as the replacement of a routing protocol or the modification of its configuration, can improve the scalability, manageability, security or the performances of the entire network. However, such migrations are an important source of concerns for network operators as the reconfiguration campaign can lead to long and service-affecting outages. In this work, we propose several techniques to address the problem of seamlessly (i.e. without loosing IP packets) modifying the configuration of commonly used routing-protocols.

NCGuard: Network Configuration Safeguard

lvanbeve — Sun, 13 Jul 2008 16:13:03 +0000

Overview

Today, most IP networks are still configured manually on a router-by-router basis. This is error-prone and often leads to misconfiguration.

NCGuard is a tool that allows a network architect to apply a safer methodology by generating validated network configuration. NCGuard relies heavily on software engineering techniques.

Let BGP speakers configure their iBGP sessions on their own

ISPs face many problems with the current iBGP. First,
operating iBGP is costly as it requires human configuration
and supervision of all the iBGP sessions. This configuration
is error prone and hard to troubleshoot. Secondly, the intro-
duction of Route Reflectors, to solve scalibility issues, has led
to a reduced path diversity within the routers of the network.
It has been showned that Losses of Connectivity are often
caused by routing failures [1], and iBGP is often responsible
of these. This low performance system does not fit for the
