Embodiment Construction

[0028] see figure 1 , which is a multicast-based multiplex section protection multiplex section protection (Mulitiplex Section Protection, MSP) system 100 provided in the embodiment of the present invention, which is used for all At least one emulation disk is used for port protection, and the services delivered by the Ethernet disk 200 are configured in a multicast manner between the cross-connect disk 300 and the main control disk 400 and at least one emulation disk 500 . Each port of each emulation disk 500 includes a receiving / sending switch for receiving / sending services. The MSP protection system 100 includes a service configuration module 120, an MSP protection configuration module 140 and at least one control module 160, the service configuration module and the MSP protection configuration module are all set in the main control panel, the Each control module 160 is correspondingly arranged in each of the emulation disks 500 respectively. It can be understood that the ...

Abstract

The invention provides a multiplex section protection (MSP) method based on a multicast way, and aims to protect emulation disks in a circuit emulation service. The MSP protection method comprises the following steps: setting a receiving / transmitting switch on each port of each emulation disk to receive / transmit a service; during service configuration on a corresponding port, judging whether or not the corresponding port is configured with MSP protection, if not, establishing a service on the corresponding port, and if so, judging whether or not the port is a master port according to a set master-standby port relation; if so, establishing a service on the master port, configuring the service on a corresponding standby port according to the set master-standby port relation, and setting a receiving / transmitting switch on the standby port according to an MSP protection way; if not, establishing a service on the standby port. According to the method, the service configured on the emulation disk on which the main port is positioned is configured on the emulation disk where the standby port is positioned in the multicast way, so that convenience is brought to service switching of the master and standby ports. The invention further provides an MSP protection system based on the multicast way.

Description

technical field [0001] The present invention relates to circuit emulation service (Circuit Emulation Service, CES), in particular to a multiplex section protection system and protection method based on multicast mode. Background technique [0002] At present, the Circuit Emulation Service (CES) is a technology that transmits the synchronous data stream in the PDH / SDH digital series in the packet-switched network, and builds a virtual private line service (Virtual Private Line Service) on the packet-switched network. Wire Service, VPWS) service "channel", the TDM service packet generated from the emulation disk is sent from the Ethernet disk to add a header, and encapsulate each E1 with IP packet, Multi-Protocol Label Switching (Multi-Protocol Label Switching, MPLS) packet, etc. Or T1 frame, the encapsulated service packet is transparently transmitted to the peer end through the packet switching network. The destination Ethernet disk regenerates the synchronous clock signal ...
