Abstract
In one embodiment, a method associated with a multiple I-service registration protocol (MIRP) includes receiving into an 802.1ah I-component an MVRP TCN from an 802.1ad component. The TCN may be received, for example, from an 802.1ad bridge. The TCN may identify an affected service using an S-VID. Therefore, the example method may include identifying the S-VID specified by the TCN. The method may also include identifying I-SIDs related to the S-VID. The I-SIDs may be identified by consulting an S-VID to I-SID translation table associated with the 802.1ah I-component. The method may also include providing an 802.1ah MIRP PDU to another 802.1ah component. The MIRP PDU may be based on the MVRP TCN and on the I-SID.
Claims21
A non-transitory computer readable medium containing a program which, when executed, performs an operation comprising:
- receiving one of, a VLAN registration, and a topology change notification (TCN) in a first 802.1ah I-component;
- identifying a service VLAN identifier (S-VID) associated with the TCN, where the S-VID is associated with a service in a network from which the TCN was received;
- identifying an instance service identifier (I-SID) related to the S-VID;
- and
- selectively providing an 802.1ah multiple instance service registration protocol (MIRP) protocol data unit (PDU) to signal a second 802.1ah component to ignore an association between a customer-space media access control (MAC) address and a b-space I-component MAC address, where the association is related to the service.
An apparatus, comprising:
- a topology change notification (TCN) logic to receive a TCN from an 802.1ad device, where the TCN logic is associated with a first 802.1ah 1 component associated with a provider backbone bridge (PBB) cloud;
- a translation logic to translate a service VLAN identifier (S-VID) to an instance service identifier (I-SID), where the S-VID is associated with the TCN and where the S-VID identifies a service known to the 802.1ad device;
- and
- a multiple I-service registration protocol (MIRP) logic to produce a MIRP protocol data unit (PDU) that is based, at least in part, on the TCN, the S-VID and the I-SID, where the MIRP PDU is to control a second 802.1ah I-component associated with the PBB-cloud to relearn an association between a customer-space media access control (MAC) address and a B-space I-component MAC address, where the association is related to the service.
A system, comprising:
- means for receiving one of, a VLAN registration, and a topology change notification (TCN) in a first 802.1ah I-component;
- means for identifying a service VLAN identifier (S-VID) associated with the TCN, where the S-VID is associated with a service in a network from which the TCN was received;
- means for identifying an instance service identifier (I-SID) related to the S-VID;
- and
- means for selectively providing an 802.1 ah multiple instance service registration protocol (MIRP) protocol data unit (PDU) to signal a second 802.1ah component to ignore an association between a customer-space media access control (MAC) address and a b-space I-component MAC address, where the association is related to the service.
