Embodiment 1

[0035] As shown in Figure 4, the chassis device consists of two chassis, one of which is the master chassis and the other is the slave chassis. The inter-chassis cascading interface of the master switch of the master The inter-chassis cascading interface is connected through a cable, and the inter-chassis cascading interface of the standby switch of the master frame is connected with the inter-chassis cascading interface of the standby switch of the slave frame through a cable. According to different application environments, the switches can also be connected by other means such as optical cable or wireless.

[0036] The method of using the above-mentioned equipment to send messages is shown in Figure 6:

[0037] Step 1: Generate an address table from the addresses of all main processing boards and service boards in the device, and store the address table in each main processing board and service board. The address table generally stores the link layer address of each circuit...

Embodiment 2

[0044] As shown in Figure 5, the chassis device consists of five chassis, one of which is the master chassis, and the other four are slave chassis. The inter-chassis cascading interface of the standby switch of the main frame is connected to the standby inter-frame switch through cables, and the master switch of each slave frame is connected to the master inter-frame switch Connect to the standby interframe switch through cables. According to different application environments, the switches can also be connected by other means such as optical cables or wireless.

Abstract

The invention discloses a framework for the equipment and its sending method of message. In each frame, set a main switchboard and a standby switchboard. Each main processing board and operational plate connects to the main switchboard and standby switchboard respectively in the frame. Machine frames are connected each other through the cascade interface provided by the main switchboard and the standby switchboard. Since the invention uses a switchboard for connecting the various circuit boards, and switchboard directly provides cascade interface between frames, so the wiring between frames is greatly simplified, which is easy to install and maintenance.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a communication frame device. The invention also relates to a method for sending messages by using the frame equipment. Background technique [0002] Shelf equipment is a kind of equipment used in network communication. A chassis is generally composed of the active main processing board, the standby main processing board and several service boards. The active main processing board, the standby main The bus is connected. [0003] At present, due to the higher and higher requirements of the communication network for the interface capacity and switching capacity of the equipment, the single-chassis system has been difficult to meet the growing demand. It has become a trend to increase the equipment system capacity by cascading two or more chassis. Multi-chassis cascading refers to the use of cascading technology to interconnect the original single-chassis devices to ...
