Data transmission method of network equipment based on multinetwork card and device

Abstract

The invention provides a data transmitting method for network device based on multi network card, which includes: the virtual network card of the network device based on multi network card is created; the address of at least one physical network card in the network device is acquired; the address of the virtual network card is arranged as the address different to the acquired address of at least a physical network card; the network device carries on data transmission according to the virtual network card with different address, and the physical network card; the invention also provides a data transmitting device of a network device based on multi network card, which includes: virtual network data memory model, address setting model, data transmitting model; the invention saves the network device resources, upgrades the data transmitting speed.

Description

technical field [0001] The invention relates to the technical field of network communication, in particular to a data transmission method and device for network equipment based on multiple network cards. Background technique [0002] In today's computer field, the network has become very popular. The rapid development of Intranet (intranet) and Internet (Internet) has made network access more and more frequent, and users have more and more requirements for network bandwidth and network access speed. high. Network cards in network equipment have developed from 10M network cards, 100M network cards to Gigabit network cards with the user's requirements for network access speed. [0003] Although increasing network bandwidth can be achieved by upgrading the network card and selecting a higher-speed network card, the upgrade of hardware equipment may require the overall upgrade of the original supporting network equipment such as hubs, switches, routers, etc. In this case, use t...

Problems solved by technology

[0008] The current network card binding technology will cause some abnormal phenomena when the network device is transmitting data. For example, when the peer connected to the network device, such as a switch, does not support round-robin operation, the switch will think that it is connected to it. It is a wrong behavior to have multiple ports with the same physical address, which will cause the switch to work abnormally; when the physical network card of the network device is directly connected to the hub, it will cause the data sent from the remote end to be repeatedly received by the network device, causing the Network devices cannot implement parallel operations when receiving and sending data

To sum up, when using the current network card binding technology for data transmission, it will cause problems such as wasting the bandwidth of the network device, wasting the processing time of the processor of the network device, and reducing the data transmission rate.
