OSPF Graceful Link Shutdown

2018
When a link is being prepared to be taken out of service, the traffic needs to be diverted from both ends of the link. Increasing the metric to the highest value on one side of the link is not sufficient to divert the traffic flowing in the other direction.

Conformance testing of OSPF protocol

IET Conference on Wireless, Mobile and Multimedia Networks, 2008
Open Shortest Path First (OSPF) is a widely used protocol for routing within an autonomous system (AS) domain. It has been gaining support as the most popular Interior Gateway Protocol (IGP) used in IP networks. The development of OSPF began in 1987 by the Internet Engineering Task Force (IETF) to address problems related to the ongoing growth of the ...

Experience in black-box OSPF measurement

Proceedings of the First ACM SIGCOMM Workshop on Internet Measurement Workshop - IMW '01, 2001
OSPF (Open Shortest Path First) is a widely used intra-domain routing protocol in IP networks. Internal processing delays in OSPF implementations impact the speed at which updates propagate in the network, the load on individual routers, and the time needed for both intra-domain and inter-domain routing to reconverge following an internal topology or a

Comparison Between IPv4 and IPv6 using OSPF and OSPFv3 on Riverbed Modeler

International Workshop on Ant Colony Optimization and Swarm Intelligence, 2019
In multiple path networks, the routing protocols are used to find the low-cost shortest path and the protocols which give its best measurements are selected for network execution. The IP addresses play a vital role in the working of the internet but IPv4

Optimization of OSPF Routing in IP Networks

2009
The Internet is a huge world-wide packet switching network comprised of more than 13,000 distinct subnetworks, referred to as Autonomous Systems (ASs) . They all rely on the Internet Protocol (IP) for transport of packets across the network. And most of them use shortest path routing protocols , such as OSPF or IS-IS, to control the routing of IP ...

Performance Evaluation DMVPN Using Routing Protocol RIP, OSPF, And EIGRP

2018 6th International Conference on Cyber and IT Service Management (CITSM), 2018
DMVPN is a VPN that uses multicast mechanism, using DMVPN we can make a lot of VPN networks. Many companies use DMVPN to communicate securely over the internet network rather than similar solutions like frame relay and ATM.

OSPF flooding process optimization

HPSR. 2005 Workshop on High Performance Switching and Routing, 2005., 2005
In this paper we study the optimization of the OSPF flooding process. When the topology of the network changes the OSPF adapts the routing to the new situation by calculating the forwarding tables that are used to forward the data traffic in the network. Before the routing table calculations the new state information needs to be disseminated throughout

Improving OSPF Dynamics on a Broadcast LAN

SIMULATION, 2006
In this article, the authors propose modifications to OSPF's interface state machine to reduce the time/processing requirements of the leader election process in a broadcast local-area network (LAN) environment. The proposed modifications are based on dynamic adjustment of wait time duration rather than using a static value.

Simulation of network topologies - a model for OSPF

IEE Mobility Conference 2005. The Second International Conference on Mobile Technology, Applications and Systems, 2005
There is a deliberate need for large-scale simulation of various networking protocols in order to understand their dynamics. With a host of routing algorithms it becomes important to monitor issues like cascading failures, inter/intra-domain routing stability, and interactions of policy-based routing.

OSPF PROTOKOL

2020
This papper presents basic OSPF protocol characteristics and also his advanced characteristics. The work can be categorically divided into two parts: The first part refers to the general part where the basic concepts such as routing, routing algorithms and basic routing protocols will be presented.
