Problems solved by technology

However, the protocol model defined by the standard protocol can be well adapted to use in a pure layer 2 switching network, but in an MPLS network, especially on an access link (AttAChment Circuit, AC for short), the adaptability is not particularly good
Only sub-interfaces of the AC interface have corresponding VLANs, and there are multiple sub-interfaces under a main interface. If a sub-interface is added to the ERPS ring each time, the VLANs of the data flow to be blocked are distributed on different sub-interfaces. It will lead to a large number of rings, a serious waste of system resources

Embodiment 1

[0016] see figure 1 As shown, the embodiment of the present invention provides a kind of application method of ERPS agreement on MPLS network:

[0017] Add the AC main interface to the ERPS ring; configure the VLAN of one of the AC sub-interfaces under the AC main interface to be consistent with the control VLAN of the ERPS ring; configure the VLANs of other AC sub-interfaces under the AC main interface to be consistent with the VLANs of the ERPS ring The instance VLANs are the same.

[0018] The present invention adds the AC main interface instead of the AC sub-interface into the ERPS ring, and overcomes the ERPS ring that causes the VLANs of the data flow to be blocked to be distributed on different sub-interfaces when a sub-interface is added to the ERPS ring each time. Too many rings waste system resources, and the ERPS protocol is applied to the MPLS network, and the data transmission stability is higher.

[0019] see figure 1 As shown, the VLAN configuration is consis...

Embodiment 2

[0023] The following example illustrates the specific application model of adding the AC main interface to the ERPS ring. see figure 2 As shown, the MPLS network is provided with a CE device, and a first UPE and a second UPE respectively communicatively connected to the CE device, and the AC main interface of the first UPE and / or the second UPE is added to the ERPS ring.

Abstract

The invention discloses an application of an ERPS protocol on an MPLS network, and relates to the technical field of Ethernet communication. The invention adds an AC main interface to an ERPS main ring, and at the same time uses a VLAN of a sub-interface under the AC main interface as a protocol message The channel controls the ERPS state machine, calculates whether the AC sub-interface in the ERPS ring is blocked / unblocked through the ERPS protocol state machine, and overcomes the VLAN of the data flow to be blocked in the ERPS ring where a sub-interface is added each time Distributed on different sub-interfaces, resulting in too many ERPS rings and wasting system resources, the ERPS protocol is applied to the MPLS network, and the data transmission stability is higher.

Description

technical field [0001] The invention relates to the technical field of Ethernet communication, in particular to an application method of an ERPS protocol on an MPLS (Multiprotocol Label Switching, multi-protocol label switching) network. Background technique [0002] ERPS is a link layer protocol specially applied to the Ethernet ring. It can prevent the broadcast storm caused by the data loop in the Ethernet ring; when a link on the Ethernet ring is disconnected, it can quickly activate the backup link to Restore communication between the nodes on the ring network. The ERPS protocol has the characteristics of fast topology convergence (less than 50ms) and the convergence time has nothing to do with the number of nodes on the ring network. However, the protocol model defined by the standard protocol can be well adapted to use in a pure layer 2 switched network, but not particularly adaptable to an MPLS network, especially an access link (AttAChment Circuit, AC for short). ...
