  • PIM Backup Designated Router Procedure
    2019
    Co-Authors: Mankamana Mishra
    Abstract:

    On a multi-access network, one of the PIM Routers is elected as a Designated Router (DR). On the last hop LAN, the PIM DR is responsible for tracking local multicast listeners and forwarding traffic to these listeners if the group is operating in PIM-SM. In this document, we propose a mechanism to elect Backup DR on a shared LAN. A Backup DR on LAN would be useful for faster convergence. This draft introduces the concept of a Backup Designated Router (BDR) and the procedure to implement it.

  • IP multicast implementation based on the multicast extensions to OSPF protocol
    2000 IEEE International Conference on Personal Wireless Communications. Conference Proceedings (Cat. No.00TH8488), 1
    Co-Authors: P.g. Ranjitkar, I.m. Suliman, P. Geil, Martijn Kuipers, Ramjee Prasad
    Abstract:

    This paper describes an IP multicast implementation based on multicast extensions to open shortest path first (MOSPF) protocol. The MOSPF forwarding model presented in this study is used to forward multicast datagrams. The forwarding model has focused on interaction between MOSPF and OSPF in terms of group-membership link state advertisement (type-6 LSA) as well as developing a multicast routing table (MRT) and multicast forwarding cache (MFC). The MRT has been organised as a Patricia-based tree while the MFC has been maintained as hash-table data structures. The MFC entries are built from the local group database and the shortest path first (SPF) tree calculation. Since MOSPF protocol can only be deployed in networks running OSPF protocol, routing functionalities, such as flooding process, forming adjacencies, election of the Designated Router (DR) and the Backup Designated Router (BDR), will be provided by the OSPF protocol. Implementation of MOSPF is required since MOSPF is the only multicasting routing protocol that can be configured for hierarchical multicast routing and also support for IP multicast's expanding ring search. In addition to that, MOSPF, like the other dense mode multicast routing protocols-distance vector multicast routing protocol (DVMRP) and protocol independent multicast (PIM) dense mode-is effective in commercial Internets.

  • Research of OSPF routing protocol based on the virtual machine
    Journal of Zhengzhou University of Light Industry, 2012
    Co-Authors: Deng Lu-juan
    Abstract:

    In order to solve the interconnection problems of a company network,meet the requirements of the stability,reliability,adaptability and flexibility network,a simulation of the company network based on the virtual machine platform was made.It achieved success in solving some problems such as the interconnection of the network,the election intervention of Designated Router/a Backup Designated Router,the generation intervention of the best path,the improvement of open shortest path first(OSPF) network safety through the measures such as starting routing and remote access service and configuring OSPF routing protocol,modifying interface priority and RouterID,modifying interface cost,setting OSPF interface password,configuring the inbound and outbound filters.
