Embodiment Construction

[0051] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments, but not as a limitation of the present invention.

[0052] As shown in Fig. 1(a), it is a relatively simple ZESR single-ring and STP hybrid network topology of the first embodiment. The method for preventing the loop includes the following steps, see Figure 4 :

[0053] Step A: configure the nodes S1 to S4 to be the same ZESR domain and enable the ZESR protocol, and S1 is the Master (master) node;

[0054] Step B: All nodes S1 to S5 enable the STP protocol, and configure the instance where the service VLAN is located, that is, the protection instance 1, including service VLANs 100 to 200;

[0055] Step C: For ports within the ZESR domain (ie, ZESR ports), the STP protocol relinquishes the management of the ZESR ports under the protection instance; and

[0056] Step D: Configure nodes S1 to S4 in the ZESR domain as MST...

Abstract

The invention discloses a method and a device for ZESR and STP hybrid networking to realize service interconnection; wherein, the method comprises the steps of: a configuration step, configuring all nodes of ZESR domains to cause the nodes to pertain to the same ZESR domain and enabling the ZESR protocol; an establishing step, enabling the STP protocol for all nodes in a ZESR and STP hybrid network and establishing ZESR protocol protection examples by utilizing the STP protocol; an abandoning step, the STP protocol abandoning the management of ZESR ports under the ZESR protocol protection examples and leaving the management to the ZESR protocol. The method and the device of the invention effectively fulfill the service interconnection in the ZESR and STP hybrid network, efficiently prevent problems happening to closed loops, therefore, radically avoiding the reduction of network performance or the paralysis of network as a result of closed loops, the invention also enlarges the application scope of ZESR networking, guarantees reliable service and stable operation and improves the quick recovery ability of ZESR under the situation of complex network topology.

Description

technical field [0001] The invention relates to the technical field of ring network protection, in particular to a method and a device for supporting ZESR and STP hybrid networking to realize service intercommunication and prevent loops. Background technique [0002] ZESR (ZTE Ethemet Smart Ring, ZTE Smart Ethernet Ring) defines an automatic protection method for Ethernet rings that supports hierarchical division. It decomposes the complex network loop detection work into simple, hierarchical and localized detection processes, and fundamentally solves the problem of Ethernet ring network fault protection switching in the case of complex ring network topology. It avoids the situation that the network is unavailable due to the closed loop caused by the fault, improves the anti-fault capability of the ring network, expands the application scope of the network, and greatly guarantees the reliable and stable operation of the business. [0003] The characteristic of ZESR is that ...
