TWI231122B - Method for balancing load of network interface card testing - Google Patents

Abstract

A method for balancing load of network interface card testing employs client/server structure. Firstly, connect the client computer installed with multiple network interface cards (NIC) to the network integrated by multiple server computers. Then scan NIC to acquire IP address of each NIC accordingly. Further manually assign or automatically allocate server from server list for each NIC and establish parameter structure allocated for the NIC. Finally, proceed tests to the multiple NICs simultaneously based on the allocated parameter structure. While designating any NIC to conduct connection test, it effectively prevent the fault report of program appeared in testing end resulting from no immediate reply to huge services request for server staying busy state, significantly reducing the error caused by network traffic jam and focusing on NIC hardware testing.

It is a network system that provides data exchange and resource sharing. One of the main devices that make up a LAN is a network card. Network Interface Card is referred to as Network Card (N IC). The network card provides a physical connection for data communication between computers. Once each computer is connected to the network, a network card must be installed. The network card is an essential basic device in the computer network. The failure of the network card not only affects the workstation itself, but also often affects the normal operation of the entire network. At present, there are many test methods for network cards, most of which adopt server / client architecture. The conventional test methods are "many-to-one" connection mode, that is, the tested multiple network cards only correspond to the same server, which is the same as the same server. Server connection test. Please refer to "Figure 1". "Figure 1" is a schematic diagram of the conventional network card testing using server / client architecture. When the "many to one" connection method is used in the figure, n The network card is connected to a server 10. When multiple clients send test requests, if server 10 is busy, a large number of test service requests will not be responded in real time, which will cause the program under test to be tested. An error is reported, which often causes errors due to network congestion during the test. Network failures caused by network card failures are often difficult to determine. This is because network failures caused by network card failures are different, and devices with faults are often not Is a malfunctioning device. When using π many pairs

The network card has a physical address that uniquely represents its address, which is written in ROM. Then for the scanned network card-manually or automatically configure the server, multiple network cards on the same client can be configured with the same server or different servers. This is also a feature of the present invention. Then, configure the parameter structure for each network card, so that each network card has a configuration parameter structure table. With the configuration parameter structure table, you can add a contract. According to the different workstations in the network, the server can transfer data between the servers due to the existence of the protocol. In order for communication to be successful and reliable, all hosts on the network must use a uniform convention. Therefore, strict standards must be developed to define every bit in every word in every packet between hosts. These standards come from the efforts of multiple organizations to agree on a common communication method, or agreement. Together with the network card, the protocol is a facility that provides communication between network applications. The present invention can specify different protocols for each tested network card according to configuration parameters. For example, TCP / IP protocol group, Transmission Control Protocol / Internet Protocol (Transmission Control Protocol / Internet Protocol) TCP or UDP protocol at the transport layer. The network card also needs to create a socket before testing. The socket is the basis of communication. A socket is the end of communication. Bind the created socket to the private IP address of f, so that the network card can communicate with the specified server. After that, you can send information to each other.
