Embodiment Construction

[0029] Figure 5 The realization scheme of UNI interface using in-band DCC as IP control channel is given. Inside the network node 150, it is divided into a control unit 151, a DCC access processing unit 153 and each controlled single disk (including multiple single disks including 2.5G optical transponder disk or tributary interface disk, cross disk, etc.), The three communicate through the backplane communication bus 300 and the Layer 2 Ethernet switch or the switching HUB152. The internal communication port of each unit is configured with an internal IP address to ensure the correct transmission of information.

[0030] Image 6 The protocol data flow diagram of using in-band DCC to transmit UNI signaling is given (taking the direct use of IP protocol transmission as an example): The process of transmitting UNI signaling at the sender is roughly as follows: UNI signaling-->IP-->PPP- ->HDLC-->DCC. On the receiving end, the exact opposite is done. The process of receivin...

Abstract

UNI signaling is transferred in physical layer through data communications channel (DCC) of synchronous digital hierarchy (SDH). DCC access processing unit at node end of automatic switch optical network (ASON) Adapts and ends UNI signaling, and transfers signaling information to control unit of ASON. Based on condition, DCC access processing function can be realized by network management unit, or optical forwarding disk or brunch interface disk. There are control unit of ASON, DCC access process unit and controlled each single disk, which carry out communication through communication bus at back plate and two layer Ethernet exchanger or exchange type HUB inside network node 150. Internal IP address is configured in internal communication port of node of each unit in order to guarantee information transferred correctly.

Description

technical field [0001] The invention relates to a client network interface method using a data communication channel as an IP control channel, that is, a physical implementation method of a client network interface (UNI) in an automatic switching optical network, which can be applied to synchronous digital series SDH equipment or using POS (IP Over SDH, SDH-based IP service) interface access router and other customer equipment access automatic switching optical 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 switched connection can make the user automatically request the optical channel c...
