This document provides an overview of the Source-Specific Multicast(SSM) service and its deployment using the PIM-SM and IGMP/MLDprotocols. The network layer service provided by SSM is a 'channel',identified by an SSM destination IP address (G) and a source IPaddress S. The IPv4 ...
6.5.2 Source Specific Multicast Source Specific Multicast (SSM) is a multicast protocol optimized for one too many applications. The approach adopted by SSM is to have the membership on the basis of an (S, G) pair—referred to as a channel. S indicates the unicast source from which the ...
IGMPv3—Among other features, IGMPv3 (RFC 4604) optimizes support for a single source of content for a multicast group or source-specific multicast (SSM). (RFC 1112 supported both many-to-many and one-to-many multicast, but one-to-many is considered the more viable model for the Internet...
By default, the address of a Source-Specific Multicast (SSM) group ranges from 232.0.0.0 to 232.255.255.255. If a user joins a multicast group whose IP address is not in this range, configure an SSM group policy in the VLAN to add the multicast group address to the range of SSM group...
The default SSM group address range is 232.0.0.0 to 232.255.255.255. An IGMP proxy device provides the SSM service for hosts only when it receives Report messages with group address in this range. Sometimes, the SSM group address range must be narrowed to ensure security of a multic...
Analysis and simulation show that its forwarding state overhead, control message overhead, average tree setup delay and average packet delay are smaller than or equivalent to existing multi-source multicast solutions based on SSM, when each participant is both sender and receiver. It combines the...
“drinking from the firehose” is an understatement to what this event is all about. One of the companies that presented to us was Teridion who bill themselves as the Waze of the Internet. Their platform takes an overview of the Internet and finds those pesky traffic jams in order to ...
2. State-of-the-Art Overview of DES Data Models and DES Integration Approaches The past decade has seen record numbers of DES growth and this trend will continue presumably over the next decades [15] (pp. 198–202). Therefore, various investigations and case studies have been conduc...
IGMPv3—Among other features, IGMPv3 (RFC 4604) optimizes support for a single source of content for a multicast group or source-specific multicast (SSM). (RFC 1112 supported both many-to-many and one-to-many multicast, but one-to-many is considered the more viable model for the Internet...
In this model of one-to-many multicast, called Source-Specific Multicast (SSM), a receiving host specifies both a multicast group and a specific sending host. The receiving host would then receive multicasts addressed to the specified group, but only if they are from the specified sender. ...
