System and method for replaying network captures
View Patent ↗There is disclosed a system and method for replaying a network capture comprising loading a network capture file that displays at least one traffic flow comprising a sequence of packets, selecting at least one packet to display on a viewer and transmitting the network traffic to a device under test wherein the selected packet is displayed on the viewer when the packet is transmitted to the device under test.
1. A method for replaying a network capture, comprising:
loading a network capture file comprising traffic and data that was transmitted on a network at an earlier time, wherein the traffic and data comprise a plurality of traffic flows comprising a sequence of packets;
displaying, on a graphical user interface, at least one traffic flow comprising a sequence of packets, wherein the sequence of packets comprises a plurality of request packets and a plurality of response packets;
selecting at least one request packet and one response packet from the traffic flow;
initializing a server to store the at least one request packet and at least one response packet when it is replayed, wherein the server allocates enough memory to store the request packet and the response packet;
replaying the traffic flow comprising the selected request packet and selected response packet; and
displaying the selected request packet and the selected response packet on a viewer when the selected request packet and the selected response packet are transmitted to the server on the network.
2. The method of claim 1 , wherein as the traffic flow is replayed, determining whether the incoming request packet matches the response packet.
3. The method of claim 2 , further comprising selecting a second request packet from the traffic flow that is displayed on the viewer.
4. The method of claim 2 , wherein the response packet that matches the request packet is transmitted on the network.
5. The method of claim 1 , displaying the selected packet and the second selected packet.
6. The method of claim 1 , wherein the selected packet is an Internet Message Access Protocol (IMAP) packet.
7. The method of claim 1 , wherein the selected packet is a Simple Mail Transfer Protocol SMTP packet.
8. A system for replaying a network capture, comprising;
a server device comprising;
a processor;
a memory;
wherein the processor and the memory comprise circuits and software for
loading a network capture file comprising traffic and data that was transmitted on a network at an earlier time, wherein the traffic and data comprise a plurality of traffic flows comprising a sequence of packets;
displaying, on a graphical user interface, at least one traffic flow comprising a sequence of packets, wherein the sequence of packets comprises a plurality of request packets and a plurality of response packets;
selecting at least one packet from the traffic flow to display on a viewer;
initializing a server to store the selected packet when it is replayed, wherein the server allocates enough memory to store the selected packet;
replaying the traffic flow comprising the selected request packet and the selected response packet; and
displaying the selected request packet and the selected response packet on a viewer when the selected packet is transmitted to the server on the network.
9. The system of claim 8 , wherein the selected packet is a Hyper Text Transfer Protocol (HTTP) packet.
10. The system of claim 9 , further comprising selecting a second packet from the traffic flow that is displayed on the viewer.
11. The system of claim 10 , displaying the selected packet and the second selected packet.
12. The system of claim 11 , wherein the selected packet is an Internet Message Access Protocol (IMAP) packet.
13. The system of claim 12 , wherein the selected packet is a Simple Mail Transfer Protocol (SMTP) packet.
