    • The invention relates to a method for real time testing of TCP traffic in a network, the method comprising: (a) connecting a tester to the network; (b) requesting connectionless traffic from a remote device connected to the network, to the tester; (c) generating the connectionless traffic comprising a plurality of packet streams, with the remote device, and receiving the connectionless traffic by the tester; (d) generating TCP traffic comprising a plurality of TCP sessions between the tester and the remote device; and, (e) concurrently with steps (c) and (d), in real time collecting statistics of the TCP sessions using the tester. The tester has an-FPGA implemented traffic engine, including a TCP state machine, for generating and receiving traffic at the rates of at least 1 gigabit per second, and for collecting statistics in real time.
    • 本发明涉及一种用于网络中TCP流量的实时测试的方法,所述方法包括:(a)将测试器连接到网络; (b)向连接到网络的远程设备请求无连接流量; (c)与所述远程设备一起生成包括多个分组流的无连接业务,并由所述测试者接收所述无连接业务; (d)生成包括所述测试者和所述远程设备之间的多个TCP会话的TCP流量; 和(e)与步骤(c)和(d)同时使用测试仪实时收集TCP会话的统计数据。 测试仪具有FPGA实现的流量引擎,包括TCP状态机,用于以至少1吉比特/秒的速率生成和接收流量,并实时收集统计信息。
