Description
Technical Field

Background
A router is a hardware device that connects two or more networks, acts as a gateway between the networks, and is a dedicated intelligent network device that reads the address in each packet and then decides how to transmit. It is capable of understanding different protocols, such as the ethernet protocol used by a certain local area network, the TCP/IP protocol used by the internet. Thus, the router can analyze the destination addresses of data packets transmitted by various different types of networks and convert the addresses of non-TCP/IP networks into TCP/IP addresses or vice versa; and then transmitting each data packet to the designated position according to the selected routing algorithm according to the optimal route. So a router can connect a non-TCP/IP network to the internet, link aggregation is a computer network term referring to a plurality of physical ports aggregated together to form a logical port to realize the load sharing of the throughput of the ingress/egress traffic on each member port, and a switch determines from which member port network packets are sent to the opposite switch according to the port load sharing policy configured by the user. When the exchanger detects that the link of one member port has fault, it stops sending package on the port, and recalculates the sending port of message in the rest links according to the load sharing strategy, and the fault port is recovered and then acts as the receiving/sending port again. Link aggregation is an important technology in terms of increasing link bandwidth, implementing link transmission elasticity and engineering redundancy, however, various routing transmission technologies in the market still have various problems.
Although the multiprotocol route configuration apparatus and method disclosed in the publication No. CN101136845A implement the multiprotocol route configuration method and apparatus, in the evolution and multi-mode convergence processes of the telecommunication network, the original networking resources can be saved to the greatest extent, so that the networking resources can be continuously utilized without being wasted, but the problems that the transmission function cannot be implemented due to the port being damaged or damaged, the transmission is suspended, and even the file is lost, etc. are not solved in the existing route transmission, so we propose a route transmission implementation method based on multi-channel network link aggregation.
