Embodiment Construction

[0034] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] The core idea of ​​the present invention is to construct two data forwarding units in a message processing device that integrates the functions of an Ethernet switch and a router: a routing unit and a switching unit, the routing unit is connected to one or more routing interface units, and the switching unit is connected to one Or more than one switching interface unit, on each routing interface unit and switching interface unit, realize the search of the forwarding table, the determination of the outgoing interface and the location of the outgoing interface, so as to realize the distributed forwarding and cross-board forwarding of the WAN interface and the LAN interface .

Abstract

The invention discloses a packet processing method and packet processing unit. The method setups two data forwarding units, namely a routing unit and an exchanging unit, respectively in charge for data forwarding between different routing interface units and different exchanging interfaces; and each routing interface unit can lookup a routing forwarding table according to forwarding information in a message, accordingly determining an outlet interface and a routing interface unit the outlet interface locating at, thereby realizing the distributed forwarding of wide area networks (WAN) interface, sharing the CPU burden onto each routing interface unit, and improving the processing ability of packet. Each exchanging interface unit in the invention can also lookup the second or third forwarding table according to the forwarding information in the message, accordingly determining an outlet interface and a routing interface unit the outlet interface locating at, rather than only having the hardware forwarding function; the method can realize straddle forwarding aiming at local area network (LAN) by the exchanging unit, when the outlet interface and the inlet interface are not in a same exchanging interface unit.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a message processing device and method for integrating functions of an Ethernet switch and a router. Background technique [0002] In current networks, Ethernet switches and routers are widely used network node devices. Ethernet switches and routers have different functions and different network locations. In the current networking, the two usually need to be used together. [0003] A router works on the third layer of the Open System Interconnection (OSI, Open System Interconnection) protocol model, and has the ability to connect different types of networks and select data transmission paths. According to the forwarding information in the received data packet, that is, the destination IP address, the router searches the routing forwarding table maintained inside the router to determine the outgoing interface and the next hop address, and realizes the forwarding of...
