Routing Table Manager (RTM)

Network Protocols Layer 3 IP Routing Routing Table Manager (RTM)

DC-RTM is a source code implementation of an IP Routing Table Manager for use with Metaswitch's IP Routing Protocol products. It combines routing information from multiple routing protocols (and optionally multiple instances of each protocol) to generate an integrated master routing table for IPv4 or IPv6 addresses, and populates the corresponding forwarding tables with active routes. It also exports external routes into the routing protocols, as required. This design provides a simple way to integrate different routing protocols, while maintaining a separate forwarding table for high-performance routing lookups.

What is Internet Group Management Protocol (IGMP) / Multicast Listener Discovery (MLD)?

Network Protocols Layer 3 IGMP/MLD

Internet Group Management Protocol (IGMP) and Multicast Listener Discovery (MLD) are the Multicast Group Membership Discovery (MGMD) protocols. They are essentially the same protocol, with IGMP used for IPv4 multicast groups and MLD used for IPv6 multicast groups. These protocols are used between end systems (often desktops) and the multicast router to request data for a given multicast group.There have been three versions of IGMP, and two versions of MLD. IGMPv2 is equivalent in function to MLDv1 and IGMPv3 is equivalent to MLDv2. All versions of IGMP/MLD are widely deployed. For example, an IGMP/MLD host implementation is included in some operating systems, and the following table shows the level of support for IGMP in Microsoft Windows hosts.

What is Protocol Independent Multicast (PIM)?

Network Protocols Layer 3 IP Routing Protocol Independent Multicast (PIM)

Protocol Independent Multicast (PIM) is a collection of multicast routing protocols, each optimized for a different environment. There are two main PIM protocols, PIM Sparse Mode and PIM Dense Mode. A third PIM protocol, Bi-directional PIM, is less widely used.

What is IP routing?

Network Protocols Layer 3 IP (Internet Protocol) IP Routing

IP Routing is an umbrella term for the set of protocols that determine the path that data follows in order to travel across multiple networks from its source to its destination. Data is routed from its source to its destination through a series of routers, and across multiple networks. The IP Routing protocols enable routers to build up a forwarding table that correlates final destinations with next hop addresses.

What is multicast IP routing?

Network Protocols Layer 3 IP Routing

Multicast IP Routing protocols are used to distribute data (for example, audio/video streaming broadcasts) to multiple recipients. Using multicast, a source can send a single copy of data to a single multicast address, which is then distributed to an entire group of recipients.
