Graceful router updates in link-state protocols

Francois Clad, Pascal Merindol, Stefano Vissicchio, Jean-Jacques Pansiot, Pierre Francois
2013 2013 21st IEEE International Conference on Network Protocols (ICNP)  
Unfortunately, planned topological changes may lead to transient forwarding loops in link-state routing protocols commonly used in IP networks.  ...  As opposed to a single-link modification, the router update problem is kdimensional for a node of degree k.  ...  In this paper, we investigate the possibility for link-state IGPs to support graceful router update operations, without changing protocol specifications.  ...

Performance Comparison of OSPFV3 and EIGRP with IPv6 Network

Richard Essah, Darpan Anand
2021 Asian Journal of Research in Computer Science  
Packet Tracer 6.2.2 was used to compare the performance of routing protocols of different kinds. In the simulation, Cisco routers, switches, and generic computers were employed in the test.  ...  As a result, we advocate using EIGRPv6 as an internal routing protocol in a network of IPv6.  ...  Five types of packets: The OSPFv3 protocols Hello, LSACK (Link State Acknowledgement), LSU (Link State Update), LSR (Link State Request), and DBD (Database Description) are utilized in normal operation  ...

Routers for the Cloud: Can the Internet Achieve 5-Nines Availability?

Andrei Agapi, Ken Birman, Robert M. Broberg, Chase Cotton, Thilo Kielmann, Martin Millnert, Rick Payne, Robert Surton, Robbert van Renesse
2011 IEEE Internet Computing  
The router won't be adapting to new routing updates and is thus frozen in time, but at least it was initially in a consistent state.  ...  In a 2004 study of router reliability, hardware outages, link failures, and Border Gateway Protocol (BGP) outages were dominant causes of downtime.  ...

Improving Convergence Speed and Scalability in OSPF: A Survey

M. Goyal, M. Soperi, E. Baccelli, G. Choudhury, A. Shaikh, H. Hosseini, K. Trivedi
2012 IEEE Communications Surveys and Tutorials  
Open Shortest Path First (OSPF), a link state routing protocol, is a popular interior gateway protocol (IGP) in the Internet.  ...  Wide spread deployment and years of experience running the protocol have motivated continuous improvements in its operation as the nature and demands of the routing infrastructures have changed.  ...  The routers then send requested LSAs to each other in link state update packets.  ...

Losing control of the internet

2010 Proceedings of the 17th ACM conference on Computer and communications security - CCS '10  
CXPST extends previous work that demonstrates a vulnerability in routers that allows an adversary to disconnect a pair of routers using only data plane traffic.  ...  This surge of updates surpasses the computational capacity of affected routers, crippling their ability to make routing decisions.  ...  The Border Gateway Protocol (BGP) [32] is the de facto standard routing protocol spoken by routers connecting different ASes.  ...

A Survey of BGP Session Maintenance Issues and Solutions

Dario Vieira
2010 Network Protocols and Algorithms  
The Border Gateway Protocol (BGP) is the routing protocol that glues together the global Internet.  ...  BGP makes use of a managed session to maintain a bidirectional error-free session over which reachability information is exchanged between Autonomous Systems (ASes) in the global Internet.  ...  Routers in the former group are usually called internal routers, while routers in the latter group are called border routers in BGP, and similar names in other protocols.  ...

An efficient fault tolerant mechanism to deal with permanent and transient failures in a network on chip

Muhammad Ali, Michael Welzl, Sven Hessler, Sybille Hellebrand
2007 International Journal of High Performance Systems Architecture  
On the other hand, we propose a deterministic routing mechanism which routes packets on alternate paths when a communication link or a router suffers permanent failure.  ...  Besides that, due to electromigration of conductors, corrosion or aging factors, on-chip modules or links may suffer permanent damage.  ...  However, when a link or router fails, the routing tables are updated and routing takes place according to the newly calculated paths. The protocol is described in detail in Section 7.  ...

Avoiding Transient Loops During the Convergence of Link-State Routing Protocols

Pierre Francois, Olivier Bonaventure
2007 IEEE/ACM Transactions on Networking  
When using link-state protocols such as OSPF or IS-IS, forwarding loops can occur transiently when the routers adapt their forwarding tables as a response to a topological change.  ...  Our solution can be used in the case of a planned change in the state of a set of links and in the case of unpredictable changes when combined with a local protection scheme.  ...  Any opinions, findings, and conclusions or recommendations expressed in this paper are those of the authors and do not necessarily reflect the views of Cisco Systems.  ...
