Embodiment Construction

[0032] Figure 5 A UNI interface scheme using the public Internet 200 as an IP control channel is described. The IP control channel is separated from the data link and is an out-of-band control channel. The client UNI agent 50 is connected to the public Internet 200 using a 10 / 100M Ethernet line. The ASON control unit 151 of the network node is also connected to the public Internet 200 through a 10 / 100M Ethernet cable. Inside the network node (UNI-N) 150 , it is divided into an ASON control unit and each controlled single disk, and the two communicate through the backplane communication bus 300 and the two-layer Ethernet switch or the switching HUB152. The data channel is realized by connecting the optical or Ethernet interface 61 of the client device 60 to the optical or Ethernet interface 160 on the interface board 159 of the network node 150 .

[0033] In the present invention, both the client UNI agent 50 and the ASON control unit 151 are assigned a unique network addre...

Abstract

Public Internet is adopted as transferring channel of UNI signaling. IP control channel is separated from data link. Client UNI proxy through 10 / 100 Mb Ethernet is connected to public Internet. ASON control unit of network node through 10 / 100 Mb Ethernet is connected to public Internet, or through two layer Ethernet exchanger or exchange type HUB is connected to public Internet. Unique network address in Internet is assigned to client proxy and ASON control unit in order to guarantee signaling information transferred correctly. Inside network node, ASON control unit and controlled each single disk are communicated each other through communication bus at back plate and two layer Ethernet exchanger or exchange type HUB.

Description

technical field [0001] The invention relates to a method for implementing a client network interface using the public network as an IP control channel, which belongs to the physical realization method of a client network interface (UNI) on an optical transmission network, and can be applied to any network client device (including an IP router, multi-protocol Label switching MPLS routers, asynchronous transfer mode ATM switches, synchronous optical network SONET / synchronous digital serial SDH equipment, etc.) access to optical transport network applications. Background technique [0002] Automatically Switched Optical Network (ASON) introduces the control plane in the traditional SDH (Synchronous Digital Hierarchy) and OTN (Optical Transport Network), thus bringing a revolutionary change to the Optical Transport Network. The ASON network supports three connection modes: switched connection, soft-permanent connection and provisioned permanent connection. Among them, the switc...
