A device and method for realizing signaling communication network and network communication network channel

Abstract

The invention discloses a device and a method to achieve an information-order communication network and a management communication network channel. The device comprises an element location control monolithic board which is connected through an Ethernet interface, and at least one optical interface monolithic board; the element location control monolithic board is used to accomplish a route agreement, and to process or transmit an Ethernet message; the optical interface monolithic board is used to insert and draw the expense of an optical signal, and to adapt and transmit the optical signal messages with different patterns. By utilizing the Ethernet technology, the ECC network management information-order and the ASON information-order of an optical transfer element location apparatus can share a data bus, a three-level exchanging unit which is realized through hardware is adopted to lighten the pressure of a C P U unit; a mass-storage high-speed S C N and M C N channels are realized in a transfer apparatus with minimum cost, the device and the method not only are compatible with the prior IP over PPP outer interface, but also provide the functions of big bandwidth, low C P U load, and bus repeat using, thereby providing the support of the stronger processing ability for realizing the intellectualization of the optical transfer apparatus.

Description

technical field [0001] The present invention relates to synchronous digital system technology and optical transmission system technology, in particular to a device and method for realizing SCN and MCN channels of optical transmission equipment. Background technique [0002] In the optical transmission equipment (SDH / OTH equipment), the signaling communication network (SCN, Signaling Communication Network) and the management communication network (MCN, Management Communication Network) are the core platforms for realizing optical transmission equipment control signaling transmission and network management. [0003] The traditional SCN and MCN channels generally use two high-level data link control (HDLC, High-level Data Link Control) buses of 2Mbps to 8Mbps as the communication channels between the network element control board (NCP) and each board. The optical transmission network element equipment uses the standard IP overPPP (Point-to-Point Protocol, point-to-point protoco...
