Embodiment Construction

[0025] All EAPS domains in the EAPS system in the present invention share a control VLAN, which is used for the transmission of protocol messages. Corresponding domain IDs and protected VLANs are set for each EAPS domain, and the protected VLANs are used to transmit business data. Set a corresponding ring ID for each EAPS ring, and the protocol messages transmitted between nodes carry domain ID and ring ID information, thereby avoiding the practice of binding a dedicated control VLAN to an EAPS domain, effectively saving VLANs resource.

[0026] The specific implementation process of the protocol message transmission control method in the EAPS system of the present invention will be described below with reference to each drawing.

[0027] see figure 2 , this figure is a flow chart of the protocol message transmission control method in the EAPS system of the present invention, which mainly includes steps:

Abstract

The invention discloses a protocol message transmission control method in an ether rig net automatic protection switch system. In the invention, all EAPS fields in the EAPS system share a control VLAN, for transmitting the protocol message, arrange corresponding filed ID and protected VLAN for each EAPS field, which is used for transmitting service data, meanwhile arrange corresponding ring ID for each EAPS ring. The protocol message transmitted between nodes is carried with the field ID and ring ID information, thereby avoiding that one EAPS field must be bonded with a special control VLAN, effectively saving VLAN resource.

Description

technical field [0001] The invention relates to an automatic protection technology of an Ethernet ring network, in particular to a protocol message transmission control method in an automatic protection switching system of an Ethernet ring network. Background technique [0002] With the continuous expansion of the application scale of Ethernet in MAN and LAN, improving the stability and reliability of the network has become the focus of more and more attention. Traditional Ethernet resilience is mainly realized through OSPE, BGP (Border Gateway Protocol, Border Gateway Protocol) and STP (Spanning Tree Protocol, Spanning Tree Protocol), and its convergence speed can only be measured in minutes and seconds, which is obviously It cannot meet the requirements of real-time services such as voice and data transmission in the existing network, so EAPS (Ethernet Automatic Protection Switching, Ethernet Automatic Protection Switching) technology came into being. EAPS technology can m...
