Abstract
The invention relates to a service network port state detection and fault tolerance device which is used for managing all network ports on a server. The service network port state detection and fault tolerance device comprises a regular packet sending module, a regular detection module and a resource management module. The regular packet sending module regularly sends a ping packet of an ICMP to a specified gateway or each network port in the server so that input end flow of the network ports is enabled to regularly increase. The regular detection module regularly inquires input end flow of each network port to the flow register of each network port in the server and reports to the resource management module that the network ports of which increasing of input end flow does not reach the standard are abnormal. The resource management module inquires all load information of the abnormal network ports and transfers the load information to other network ports of which rich bandwidth can meet the load demand.
