Embodiment 1

[0021] Compared with the Crossbar architecture, the most direct difference between the CLOS architecture and the Crossbar architecture is that the control and forwarding hardware are truly separated. All the control functions of the CLOS architecture equipment are on the main control board, but the forwarding function is on the switch matrix board. The advantages of the CLOS switching architecture are: multiple switching matrix boards jointly complete the traffic exchange, increasing the switching capacity; the control plane and the forwarding plane are physically separated, the forwarding is not affected when the engine is switched, and zero packet loss can be achieved; the switching matrix board can realize N +1 for redundancy.

[0022] In the CLOS architecture, when a switch matrix board is inserted, on the one hand, in order to prevent packets from being lost after the packets are switched to the switch board, it is necessary to ensure that the MODID mapping is completed be...

Embodiment 2

[0048] Compared with the Crossbar architecture, the most direct difference between the CLOS architecture and the Crossbar architecture is that the control and forwarding hardware are truly separated. All the control functions of the CLOS architecture equipment are on the main control board, but the forwarding function is on the switch matrix board. The advantages of the CLOS switching architecture are: multiple switching matrix boards jointly complete the traffic exchange, increasing the switching capacity; the control plane and the forwarding plane are physically separated, the forwarding is not affected when the engine is switched, and zero packet loss can be achieved; the switching matrix board can realize N +1 for redundancy. Embodiment 2 of the present invention proposes a message processing method, based on the CLOS architecture, when the switch matrix card is pulled out, as Figure 4 As shown, the packet processing is specifically as follows:

Abstract

The invention discloses a message processing method and device, including: when it is determined that the switch matrix board is performing an insertion operation, enabling protocol message isolation, the protocol message isolation is used when the switch matrix board changes. Transmit the message of its own attribute information between the chip in the isolated switch matrix board and the chip of other business boards; and when it is determined that the insertion of the switch matrix board is completed, close the isolation of the protocol message; and forward the received Packets sent by service boards. It is used to solve the problem of message loss caused by the insertion or removal of the switch matrix card in the core switching equipment using the DUNE chip.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a message processing method and device. Background technique [0002] The CLOS switching architecture was first proposed by Dr. Charles Clos of Bell Labs in the paper "Research on Non-blocking Switching Networks" in 1953, and was later widely used in time-division multiplexing (English: Time-Division Multiplexing, abbreviation: TDM) network. [0003] Such as figure 1 The frame diagram of the CLOS architecture shown in the CLOS architecture includes a control board used for control functions, a switch matrix board responsible for data forwarding between service boards, and a service board that carries messages. The data traffic in the service board does not flow through the control board, but is forwarded through the switch matrix board. Among them, the physical port connecting the DUNE chip service board and the switching board is called a fabric port. There is ...
