Hi George, Many thanks for the feedback. When I have access to the system I will let you know. The network path is from my client app through a DLink 1Gbps switch up to my router then back again to the same system as the client since the app server is on that box. So I am assuming what you are talking about is on my windows box and that I should use something like TCP optimizer to check that setting.

In your TCP options field of the handshake, what is the Maximum segment size? Is there a device that is setting a smaller MTU in the path such as a router?

Hi All, More info. Each frame in wireshark is listed as having 539bytes captured and on the wire. My MTU is set to 1500 byte packets so if this is a fragmentation of data why would the data be split into two frames when one should have at least used two packets within a frame? Sorry for the questions I am a newbe to this level of analysis.

To: "Wireshark Users" <wireshark-users () wireshark org> Date: Wednesday, October 14, 2009, 9:03 AM Hi All, I am analyzing some traffic for my app usingWireshark. Icaptured a single request from my app to a web serviceandnoticed that there appeared to be a redundancy in two frames. I am seeing something called a "TCP segment ofareassembled PDU" and then my Post being sent from thesource(my client app) to the destination (web service). Andthesame sequence coming back from the destination (webservice)to the source (my client app). Does anyone know why the TCP segment of a reassembledPDUis be sent and then coming back? It looks like itcontainsthe same data or payload.
