Living with the ever-growing BGP table : an OCN story

Naoki Mashiko, NTT Communications Chika Yoshimura, NTT Communications

ISPs have to cope not only with the enormous traffic grow, but also with the increase in the number of full routes, which might cause unstable network behavior. If the current pace continues, several problems such as RIB/FIB space shortage and longer routing convergence time may arise.

RCMD: a solution for Routing Convergence Measurement and Diagnosis

Clarence Filsfils, Cisco Systems

Significant improvements in routing convergence have been made over the last 5 years: IGP convergence in a few 100's of msecs, IGP FRR (Loop Free Alternate), BGP FRR (BGP Prefix Independent Convergence), MoFRR (Multicast FRR), MLDP FRR. These have been proven in the lab, under large-scale stress situation.

However, once deployed, it is difficult to monitor their effects on a live network. Does the technology work as expected? How much gain has been obtained? Is the routing convergence improving or degrading over time? Is there any issue still unresolved? RCMD is a solution for these problems.

RCMD is a lightweight, scalable, always-on monitoring function embedded within each router that helps to measure, collect and diagnose routing convergence. Case studies will be used extensively throughout the tutorial to explain the technology and its application. RCMD will reach ""First Customer Shipment"" in 2012 on all the IOS-XR router platforms. Results from live demo’s will be included.

IPv6 research initiatives at ERNET India

Paventhan_Arumugam, ERNET

ERNET is the first network in the country to be IPv6 ready since 2005. In this presentation, we look at the IPv6 R&D initiatives at ERNET India funded by DIT in the field of Mobile IPv6 testbed for mobility management over heterogeneous network and the 6LoWPAN testbed project.
