Dynamic allocation method and apparatus of system port number

Abstract

The invention discloses a dynamic allocation method and apparatus of a system port number, and relates to the field of optical communication transmission. The method comprises the following steps: a network management system adds a single disk, and issues capacity type configuration of the newly added single disk to a main control CCU, and the main control CCU multicasts the capacity type of the newly added single disk to all single disks of a network element; when the network management system creates service mapping, the main control CCU dynamically allocates a backboard port according to the capacity type of the single disk, converts the backboard port into the system port number and issues the system port number to the single disk; and when the single disk receives the service mapping,the single disk obtains a cross network access processor serial number FAP_ID and a cross network access processor port number FAP_PORT required for driving according to the capacity type of the newly added single disk and the system port number, configures the driving and opens the service. By adoption of the dynamic allocation method and apparatus disclosed by the invention, the access of service single disk with service capacity greater than 1TG or even higher capacity can be realized.

Description

technical field [0001] The invention relates to the field of optical communication transmission, in particular to a method and device for dynamically allocating system port numbers. Background technique [0002] As mobile services enter the 3G and 4G era, a large amount of information data needs to be sent from one place to another every day. The existing information transportation methods SDH (Synchronous Digital Hierarchy, synchronous digital series), WDM (Wavelength Division Multiplexing, wavelength division multiplexing), OTN (Optical Transport Network, optical transport network), PTN (Packet Transport Network, packet transport network) Both are single data transmission methods, which cannot meet the full-service transmission requirements of high-speed TDM (Time Division Multiplexing) leased lines and packet switching at the same time, forcing people to propose a new integrated bearer information solution POTN (Packet Enhanced Optical Transport Network, Packet Enhanced ...

Problems solved by technology

Taking the maximum 64-slot subframe as an example, each slot has an average of 512 Channels; in fact, the upgraded dual NETWORK chips theoretically support 1TG ODU0 cross-connection, and need to occupy 800 Channels; If the SYSPORT resource is allocated, it will not be able to meet the access of a business single disk with a business capacity greater than 1TG or even higher capacity
