Embodiment Construction

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

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

[0054] Step B: Enable the STP protocol on all nodes S1-S5, and configure the instance where the service VLAN is located, that is, protection instance 1, including service VLAN100-200;

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

[0056] Step D: Configure nodes S1-S4 in the ZESR domain as MSTP domain 1, and configure node S5 as MSTP domain 2. Among them, MSTP (Multiple Spanning Tree Protocol) is a multiple spanning tree protocol.

[0057] The topology structure after the above configuration is shown in Figure 1(c)...

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 mixed networking to realize service interworking and prevent loops. Background technique [0002] ZESR (ZTE Ethernet Smart Ring, ZTE Intelligent Ethernet Ring Network) defines an automatic protection method for Ethernet ring networks that supports hierarchical division. Based on concepts such as roads and border nodes, the complex network loop detection work is decomposed into a simple, hierarchical, and localized detection process, which fundamentally solves the problem of Ethernet ring network fault protection switching in the case of complex ring network topologies. It avoids the situation that the network is unavailable due to a closed loop caused by a fault, improves the anti-fault capability of the ring network, expands the scope of networking applications, and greatly ensures reliable and stable operation of...
