A method for managing multi-subframe board cards with a single network element

Abstract

The invention discloses a method for managing multi-subframe board cards by a single network element, comprising: grouping subframes and setting group numbers; configuring multicast addresses on switches of network element agent units and lower board cards, and The Ethernet port for external communication is set to prohibit the passage of multicast information; the network element agent unit periodically multicasts the group number information to all ports of the switch; the board whose group number information changes is based on the new group number information and its slot address, Reconfigure the IP address, MAC address and slot address, and save the new group number information; the board sends bootstrap information and re-request configuration information to the network element management unit with the new IP address; the network element management unit records the board information according to the bootstrap information. The card's IP address, group number information and slot address, and send confirmation information and configuration data to the board. The invention not only avoids address conflicts between newly added boards and original boards, but also prevents network element managers from forwarding board data, reduces software design complexity, and improves network stability.

Description

technical field [0001] The invention relates to network equipment management technology and network capacity expansion technology, in particular to a method for managing multiple sub-frame boards with a single network element. Background technique [0002] In the era of high-speed networks, the explosive growth of data services of telecom operators generates massive business data. These business data need to be carried and transmitted by communication equipment, which puts forward higher requirements for the capacity of communication equipment and the types of services that can be supported; so It has become an inevitable trend to meet the growing data demand by expanding and upgrading the existing network equipment. [0003] The cross capacity of the communication equipment determines the capacity of the communication equipment, and the type and quantity of service ports determine the access capability of the equipment. When expanding the capacity of the device and the typ...

[0005] However, the addresses of the boards in the newly added sub-box and the boards in the original sub-box overlap. If the new sub-box and the boards directly communicate with the network element management unit, the IP, MAC and slot addresses will conflict, not only will the new board cannot be discovered and managed by the network element management unit, but will even cause the original board to be hosted, and more seriously, it will cause service interruption

If the newly added sub-frame is managed as a brand new NE, since there is no direct communication channel between the new NE board and the old NE board, the new NE board and the old NE board will not be able to Unified cross management and configuration cannot provide efficient and accurate channel protection, which wastes network resources and is not conducive to business scheduling and intelligent control of network equipment
