Selective multicast
View Patent ↗A method, system and computer readable medium for selective multicast processing. The method can include obtaining, using one or more processors, an association between a multicast data stream and a service identifier. The method can also include programming, using the one or more processors, a classification engine with a match that classifies a VLAN. The method can further include receiving, at the one or more processors, a data stream, and classifying, using the one or more processors, the data stream based on a mapping to a source virtual port. The method can also include deriving, using the one or more processors, a service identifier from the source virtual port.
1. A method for selective multicast processing, the method comprising:
establishing, at a backbone edge bridge (BEB), using one or more processors, an association between source address, group address (S, G) information of a data stream and a service instance identifier (ISID);
programming, using the one or more processors, a classification engine in the BEB with a match that classifies a Virtual Local Area Network (VLAN), wherein the match includes a specific source address, group address (S, G) match that classifies a VLAN;
listening, at the BEB, for a multicast ISID of interest to the BEB;
determining that a multicast ISID of interest to the BEB is received at the BEB;
de-encapsulating a mac-in-mac message from the multicast ISID of interest according to a corresponding multicast unique ISID and VLAN, wherein the de-encapsulating includes performing an (S,G) ternary content-addressable memory (TCAM) lookup to decide which source virtual port (SVP) to send the data stream to; and
sending, from the BEB, the data stream to interested switches based on the ISID corresponding to the (S,G) matching.
2. The method of claim 1 , wherein the data stream is an (S,G) multicast data stream.
3. The method of claim 1 , wherein the one or more processors includes a network communication chip.
4. The method of claim 3 , wherein the network communication chip is a chip having mac-in-mac capabilities.
5. A system comprising:
one or more processors coupled to a nontransitory computer readable medium having stored thereon software instructions that, when executed by the one or more processors, cause the one or more processors to perform operations including:
establishing, at a backbone edge bridge (BEB), using the one or more processors, an association between source address, group address (S, G) information of a data stream and a service instance identifier (ISID);
programming, using the one or more processors, a classification engine in the BEB with a match that classifies a Virtual Local Area Network (VLAN), wherein the match includes a specific source address, group address (S, G) match that classifies a VLAN;
listening, at the BEB, for a multicast ISID of interest to the BEB;
determining that a multicast ISID of interest to the BEB is received at the BEB;
de-encapsulating a mac-in-mac message from the multicast ISID of interest according to a corresponding multicast unique ISID and VLAN, wherein the de-encapsulating includes performing an (S,G) ternary content-addressable memory (TCAM) lookup to decide which source virtual port (SVP) to send the data stream to; and
sending, from the BEB, the data stream to interested switches based on the ISID corresponding to the (S,G) matching.
6. The system of claim 5 , wherein the data stream is an (S,G) multicast data stream.
7. The system of claim 5 , wherein the one or more processors includes a network communication chip.
8. The system of claim 7 , wherein the network communication chip is a chip having mac-in-mac capabilities.
9. A nontransitory computer readable medium having stored thereon software instructions that, when executed by one or more processors, cause the one or more processors to perform operations including:
establishing, at a backbone edge bridge (BEB), using the one or more processors, an association between source address, group address (S, G) information of a data stream and a service instance identifier (ISID);
programming, using the one or more processors, a classification engine in the BEB with a match that classifies a Virtual Local Area Network (VLAN), wherein the match includes a specific source address, group address (S, G) match that classifies a VLAN;
listening, at the BEB, for a multicast ISID of interest to the BEB;
determining that a multicast ISID of interest to the BEB is received at the BEB;
de-encapsulating a mac-in-mac message from the multicast ISID of interest according to a corresponding multicast unique ISID and VLAN, wherein the de-encapsulating includes performing an (S,G) ternary content-addressable memory (TCAM) lookup to decide which source virtual port (SVP) to send the data stream to; and
sending, from the BEB, the data stream to interested switches based on the ISID corresponding to the (S,G) matching.
10. The nontransitory computer readable medium of claim 9 , wherein the data stream is an (S,G) multicast data stream.
11. The nontransitory computer readable medium of claim 9 , wherein the one or more processors includes a network communication chip.
12. The nontransitory computer readable medium of claim 11 , wherein the network communication chip is a chip having mac-in-mac capabilities.
