Embodiment Construction

[0014] Such as figure 1 As shown, the modular network device 100 is covered and configured in a chassis 140 such as a modular routing switch, and the chassis 140 has several slots for accommodating two types of modules. The network interface modules 130 can be installed in the slots 146 in any order, but cannot be installed in the slots 142 and 144 which are specially used for installing the agent modules 110 , 120 . For the modular routing switch, the proxy module 110 (120) plays two key roles in the modular network device 100: central switch fabric and management entity. For the sake of brevity, the modular network device will be simply referred to as "system" in the following description. The network interface module 130 can learn the address of the local computer connected to it and maintain a database. When the source and destination ports of a data packet (packet) are all located in the same network interface module, the packet will stay in this network interface module...

Abstract

A recovery method from failure of main agent module of modular network equipment, wherein the main agent module executes management and system control functions, while the modular network equipment can be provided with several network interface modules in its rack. After the power is turned on, install a standby agent module on the rack, the standby agent module will judge that the main agent module has been installed previously according to the three dedicated signals of the main agent module, and then, the modular network equipment performs the main agent The configuration information of the network interface module is updated synchronously with the standby agent module. If the information sent by the main agent module is not received within a predetermined time interval, the standby agent module detects that the main agent module fails, and as a result, the modular network device restarts, and the standby agent module takes over as the main agent module .

Description

technical field [0001] The invention relates to modular network equipment, in particular to a modular switch with redundant management and system control functions. Background technique [0002] A typical computer network consists of many nodes (computers), connection media (wired or wireless), and network devices such as routers and hubs. In the case of the internet, these elements work together to allow a computer to transmit information to other computers that may be on the other side of the world. A switch is a fundamental part of most networks, allowing several users to simultaneously transmit information on a network without slowing down others, just as a router enables different networks to communicate with each other, a switch It allows different nodes in the network to directly communicate with each other in a smooth and efficient manner. [0003] In the past, a modular architecture has been developed to design network equipment. The advantage of using a modular d...
