Abstract
The invention discloses an application of an ERPS protocol in an MPLS network, which relates to the technical field of Ethernet communication.
Description
Technical Field
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) network.
Background
The ERPS is a link layer protocol specially applied to an Ethernet ring, and can prevent a broadcast storm caused by a data loop in the Ethernet ring; when one link on the Ethernet ring is disconnected, the backup link can be quickly started to restore the communication between each node on the ring network. The ERPS protocol has the characteristics of high topology convergence speed (less than 50ms) and independence of convergence time on the number of nodes on the ring network. However, the protocol model defined by the standard protocol can be well adapted to the pure two-layer switching network, and the adaptability in the MPLS network, especially the access link (attach Circuit, AC for short), is not particularly good. The AC interface has a corresponding VLAN only under the sub-interface, and there are multiple sub-interfaces under one main interface, and if a sub-interface is added into an ERPS ring at a time, VLANs of data streams to be blocked are distributed on different sub-interfaces, the number of rings is excessive, and system resources are seriously wasted. Therefore, a solution for applying the ERPS protocol to the MPLS network is needed.
Disclosure of Invention
Aiming at the defects in the prior art, the invention aims to provide an application method of an ERPS protocol on an MPLS network, which realizes the application of the ERPS protocol in the MPLS network and has higher data transmission stability.
In order to achieve the above purpose, the technical scheme adopted by the invention is an application method of an ERPS protocol on an MPLS network, which comprises the following steps:
adding an AC main interface into an ERPS ring; configuring 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; the VLANs of the other AC subinterfaces below the AC main interface are configured to coincide with the instance VLANs of the ERPS ring.
On the basis of the scheme, the VLAN is configured into an AC sub-interface consistent with the control VLAN of the ERPS ring and used for receiving and sending a protocol message of the control VLAN with the ERPS ring; and the other AC sub-interfaces are used for receiving and transmitting data messages.
On the basis of the scheme, the MPLS network is provided with CE equipment, a first UPE and a second UPE which are respectively in communication connection with the CE equipment, and AC main interfaces of the first UPE and/or the second UPE are added into an ERPS ring.
On the basis of the scheme, an ERPS state machine is controlled by taking the VLAN of the sub-interface under the AC main interface as a protocol message channel, and whether the AC sub-interface in the ERPS ring is blocked or unblocked is calculated by the ERPS protocol state machine.
On the basis of the above scheme, the blocking objects of the ERPS protocol are: the ERPS protocol state machine calculates the data traffic on the AC subinterface to be blocked and the instance VLAN under the AC subinterface.
Compared with the prior art, the invention has the advantages that:
the invention adds the AC main interface into the ERPS ring instead of the AC sub-interface, overcomes the problem that the VLAN of the data flow to be blocked is distributed on different sub-interfaces and the system resource is wasted because the VLAN of the data flow to be blocked is distributed in different sub-interfaces when one sub-interface is added into the ERPS ring at each time, and realizes that the ERPS protocol is applied to the MPLS network and the data transmission stability is higher.
