Embodiment Construction

[0120] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0121] Multiple BFRs can be included in the BIER network. According to the position of the BFR in the transmission link of the multicast message, the multiple bit forwarding routers can be divided into BFIR, intermediate BFR and BFER. Such as figure 1 As shown, the BIER network provided by the embodiment of the present invention includes: a BFIR, an intermediate BFR1, a first BFER, an intermediate BFR2, and a second BFER. The BFIR may be connected to the intermediate BFR1, and the intermediate BFR1 may be connected to the first BFER; the intermediate BFR1 may be a BFR on a link between the BFIR and the first BFER. The BFIR may be connected to the intermediate BFR2, and the intermediate BFR2 may be connected to the second BFER; the in...

Abstract

The invention provides a bit-forwarding ingress router (BFIR), a bit-forwarding router (BFR) and an operation administration maintenance (OAM) detection method and belongs to the multicast network field. An OAM request message from the BFIR is received through a first BFR; a target BFR corresponding to the OAM request message is determined by the first BFR to be the first BFR according to the OAM request message; a first OAM response message is acquired by the first BFR according to the ID of the BFIR, and the first OAM response message is sent to the BFIR. Through the method and the device, a problem that a transmission fault generated in a transmission process of a multicast message can not be diagnosed or processed by the BFIR can be solved, connectivity detection can be facilitated through the OAM message, and detection on multiple bit-forwarding egress routers (BFER) can be realized.

Description

technical field [0001] The invention relates to the field of multicast networks, in particular to a bit-forwarding entry router, a bit-forwarding router and an operation, administration and maintenance (English operation, administration and maintenance, OAM for short) detection method. Background technique [0002] Bit Index Explicit Replication (English: BitIndexedExplicitReplication; abbreviation: BIER) is a brand-new multicast technology, which realizes multicast message by setting multiple bit-forwarding routers (English: Bit-ForwardingRouter; transmission. [0003] When a bit-forwarding ingress router (English: Bit-ForwardingIngressRouter; BFIR for short) in the BIER domain sends a multicast packet to at least one bit-forwarding egress router (English: Bit-ForwardingEgressRouter; BFER for short) in the BIER domain, each The identification information corresponding to the BFER is encoded into the multicast message, and the multicast message is sent to the corresponding ...
