    摘要: Techniques disclosed herein include systems and methods for providing a scalable solution to transmit edge IP Multicast sender information in a Shortest Path Bridging (SPB) network. Control information is exchanged between Ingress Backbone Edge Bridges and Egress Backbone Edge Bridges using Multicast Flow Specific and type-length-value (TLV) structures, or other control messages, to announce available multicast streams at ingress nodes within the SPB network. Such exchanges of control messages trigger sending SPB specific Intermediate System To Intermediate System (IS-IS) TLV control message with path computation information via IS-IS control messages. This second set of control messages is exchanged within the SPB network and includes source-specific multicast stream information that is used by Backbone Core Bridges to establish a multicast forward state and compute multicast forwarding paths. Multicast data traffic can then be transmitted through the SPB network using a one-to-many distribution model.

    摘要: Techniques disclosed herein include systems and methods for improving efficiency of multicast state generation within Shortest Path Bridging (SPB) networks. Techniques include using an IS-IS TLV structure with new multicast state computation rules for SPB Networks. SPB Networks use a TLV field for the I-SID Address (and equivalent TLV fields defined in different IETF/IEEE drafts) and node nicknames to signal information that is used to compute a multicast state required to provide L2 Services over a given SPB Network. The I-SID Address TLV is set or filled to carry various items of information. These items of information can include Backbone Media Access Control (B-MAC), Virtual Local Area Network Identifier (VID), I-SID[Transmit, Receive Bit], etc.
