Embodiment Construction

[0044] Such as figure 1 Shown is a schematic structural diagram of a virtual local area network switching system according to an embodiment of the present invention. Among them, the virtual local area network switching system (VSS, Vlan Switch System) adopts a layered architecture, including a bearer capability layer 103, a connection control layer 102, a service control layer 101 and an operation management and maintenance layer (OAM management layer, Operation Administration and Maintenance) 104.

[0045] The devices mainly included in the VSS system are Data Switch Entity (DSE, Data Switch Entity) 109 , Resource Control Entity (RCE, Resource Control Entity) 108 and Service Control Entity (SCE, Service Control Entity) 105 . Through the signaling interaction among DSE109, RCE108 and SCE105, the report of link resource abnormality and the establishment, modification and removal of links are completed.

[0046] VSS has complete Ethernet VLAN switching and scheduling functions,...

Abstract

The system comprises: a service control layer networks composed of one or more service control devices; a connection control layer network compose of one or more resource control devices; and a load capacity layer network composed of one or more data repeaters. The method thereof comprises: 1) service control device initiates link request to the resource control device; 2) resource control device initiates VLAN list item request to data repeater; 3) data repeater executes the link request; 4) according to the execution result, the resource control device sends the confirmation message to the service control device.

Description

technical field [0001] The invention relates to the technical field of virtual local area network switching, in particular to a virtual local area network switching system and a method for signaling interaction between devices in the system. Background technique [0002] A local area network (LAN) is a network consisting of a few home computers or an enterprise network consisting of hundreds of computers. The LAN referred to by a virtual local area network (VLAN, Virtual LAN) specifically refers to a network divided by a router, that is, a broadcast domain. The broadcast domain refers to the range to which broadcast frames can be transmitted, that is, the range where direct communication can be performed. Strictly speaking, not only broadcast frames, multicast frames (Multicast Frame) and target unknown unicast frames (Unknown Unicast Frame) can also travel unimpeded in the same broadcast domain. [0003] The original Layer 2 switch can only build a single broadcast domain...
