  • Redundant link network test

    Redundant link network test

    With the rapid development of communication technology, network plays an increasingly important role in daily work, and Ethernet has gradually become the basis of communication in various fields.In practical network application, network link or communication equipment failure often occurs.For some applications with higher requirements on network communication quality, single link is difficult to meet the requirement of system reliability, so the redundancy scheme of double link is generally adopted for communication.

  • Network fault and damage simulation

    Network fault and damage simulation

    WS100 can do various damage simulation and fault injection for received data packets, such as bandwidth limitation, delayed transmission, message rejection, message repetition, message out-of-order, content rewriting, CRC error, packet insertion, packet filtering, port mirroring, etc.

    Through the network damage simulation and fault injection functions of WS100, developers can quickly simulate various real scenarios in the network in the laboratory, construct various abnormal network faults, and find the problems existing in the communication equipment and network system before the system goes online, so as to ensure the reliability of the network system.

  • Dual link redundant network card

    Dual link redundant network card

    The dual-link redundant communication scheme has been widely adopted at present, and the common dual-link network card in the market is generally through the link binding, fault identification and link switching by the operating system and protocol stack.It takes a long time because the software needs to perceive the failure of the hardware and do link switching on the upper layer. The switching time between the main link and the standby link declared by the general manufacturer is 90 milliseconds, that is, the time between the failure of the main link and the start-up of the standby link is 90 milliseconds.For a gigabit link, tens of thousands of data packets will be lost in 90 milliseconds, which will seriously affect the normal operation of the system.At the same time, because of the so
