  • protocol independent multicast sparse mode pim sm Designated Router dr improvement
    2020
    Co-Authors: Mankamana Mishra, Zheng Zhang
    Abstract:

    Protocol Independent Multicast - Sparse Mode (PIM-SM) is a widely deployed multicast protocol. As deployment for the PIM protocol is growing day by day, a user expects lower packet loss and faster convergence regardless of the cause of the network failure. This document defines an extension to the existing protocol, which improves the PIM protocol's stability with respect to packet loss and convergence time when the PIM Designated Router (DR) role changes.

  • pim Designated Router load balancing
    RFC, 2020
    Co-Authors: Sri Vallepalli, Andy Green, Stig Venaas, Yiqun Cai, Mankamana Mishra
    Abstract:

    On a multi-access network, one of the PIM-SM (PIM Sparse Mode) Routers is elected as a Designated Router. One of the responsibilities of the Designated Router is to track local multicast listeners and forward data to these listeners if the group is operating in PIM-SM. This document specifies a modification to the PIM-SM protocol that allows more than one of the PIM-SM Routers to take on this responsibility so that the forwarding load can be distributed among multiple Routers.

  • 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.

  • pim Designated Router graceful shutdown
    2018
    Co-Authors: Mahesh Sivakumar, Mankamana Mishra, Stig Venaas, Mikael Abrahamsson, Zheng Zhang
    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 case of a network maintenance, where we want to bring down the current DR, there is currently no way to gracefully handover the PIM DR role to a new DR on the shared LAN. In this document, we propose a modification to the PIM-SM protocol that allows PIM DR to gracefully shutdown or go down for maintenance. We also provide a procedure for PIM DR to gracefully handover its role to a new PIM DR in the network.

  • Scalable Link-State Internet Routing
    1998
    Co-Authors: J.j. Garcia-luna-aceves, Marcelo Spohn
    Abstract:

    We present and verify the Adaptive Link-State Protocol (ALP), a new link-state routing protocol that does not require the state of each link to be flooded to the entire internetwork, or to entire areas if hierarchical routing is used. A Router in ALP disseminates link-state updates incrementally to its neighbors for only those links along paths used to reach destinations. Link-state updates are validated using time stamps and contain the same information used in other link-state protocols. For the case of neighbor Routers connected through a broadcast medium, a Designated Router is distributedly elected for each link state reported over the medium, rather than requiring a Designated Router to report every topology change over the broadcast medium, like OSPF does. Simulation experiments illustrate that ALP is as efficient as the Distributed-Bellman Ford algorithm when distances to destinations do not increase and resources do not fail, and more efficient than traditional link-state prot..

Simulation experiments illustrate that ALP is as efficient as the Distributed-Bellman Ford algorithm when distances to destina-tions do not increase and resources do not fail, and more efficient than traditional link-state protocols based on flooding after dis-tances increase or resources fail. ALP also outperforms the link-vector algorithm (LVA), which is the only prior routing algorithm based on selective dissemination of link states. 1

  • IMPLEMENTASI DAN ANALISA PERFORMANSI REDUNDANCY PADA JARINGAN MULTICAST DENGAN METODE PROTOCOL INDEPENDENT MULTICAST SPARSE MODE
    Universitas Telkom, 2015
    Co-Authors: Naufal Dzulfiqar Anwar
    Abstract:

    Kebutuhan akan layanan multimedia semakin meningkat menyebabkan trafik yang ada di jaringan semakin padat. Bandwidth yang dibutuhkan menjadi sangat besar, sehingga harus menggunakan metode pengiriman data yang berbeda dari sebelumnya. Metode pengiriman data secara unicast tidak lagi menjadi pilihan karena tidak efisien. Multicast menjadi metode pengiriman data yang dipilih ketika menggunakan layanan multimedia, karena trafik yang dikirim hanya untuk group tertentu, sehingga meningkatkan efisiensi dalam penggunaan bandwidth. Redundancy Protocol digunakan untuk menciptakan High Availability pada jaringan, sehingga host akan mendapat layanan yang lebih baik. Implementasi jaringan multicast bisa dilakukan dengan protokol peroutingan Multicast Open Shortest Path First (MOSPF), Distance Vector Multicast Routing Protocol (DVMRP), dan Protocol Independent Multicast (PIM). Pada penelitian ini akan digunakan protokol Protocol Independent Multicast Sparse Mode (PIM-SM) yang termasuk ke dalam kategori group-shared tree. Protokol redundancy yang digunakan adalah Gateway Load Balancing Protocol (GLBP). Protokol ini mempunyai fitur yang unik yaitu selain menjadi gateway redundancy, protokol ini juga memiliki fitur load balancing. Hasil yang didapat dari pengujian kali ini adalah, fitur load-balancing yang ada pada protokol GLBP tidak bisa berjalan pada protokol multicast dengan protokol PIM-SM, karena hanya Designated Router yang bisa mengirimkan paket – paket protokol PIM-SM. Hasil end-to-end delay dan jitter yang didapat telah memenuhi standar ITU-T G.1010 yaitu dibawah 10 detik untuk end-to-end delay dan dibawah 1 ms untuk jitter. Pada pengukuran downtime diperoleh hasil rata – rata yaitu 94.423 detik untuk VRRP, 92.108 detik untuk GLBP, dan 15.411 detik untuk VRRP setelah optimasi. Layanan yang digunakan adalah audio streaming. Kata kunci :Multicast, Redundancy Protocols, PIM – SM, GLB
