Detection of Invalid Routing Announcements in RIP Protocol

Tags:
switching

Overview Traditional routing protocol designs have focused solely on the functionality of the protocols and implicitly assume that all routing update messages received by a router carry valid information. However operational experience suggests that hardware faults, software implementation bugs, operator misconfigurations, let alone malicious attacks can all lead to invalid routing protocol announcements. Although several recent efforts have developed cryptography-based authentication for routing protocols, such enhancements alone are rendered ineffective in the face of faults caused by misconfigurations or hardware/software errors. This paper develop a simple routing update validation algorithm for the RIP protocol, RIP with Triangle theorem checking and Probing (RIP-TP).

Live Webcast: Telecoms 2.0 - Where is telecoms heading?

In this webcast, our panel of experts will review where we are with next generation telecoms in the UK, working through the concept of 'Telecoms 2.0': - Realising the potential of Next Generation Networks - why it isn't just about the technology? - What attributes should firms be looking for in their telco partner? - Is the relationship between telco provider and customer changing? - What things need to happen to make next generation services a reality? - You say you want the supplier to change. Do you want to change too? - What is Telecoms 2.0?
