TOPIC: TCP Options - The options

TCP Options - The options 10 years 3 months ago #26434

I need to understand what option 1 means when it states the following:

Option #1: Type 2 = Maximum Segment size

Kind: 2
Length: 4
Maximum segment length: 1260

I have maximum packet size of 536 and I want to understand how that will affect the network from the user perspective and then the network perspective.

Then, of course, how does one increase the size to max (1514)

btw, the packets from the workstation start on a 100Mb link, go to a 2Mb WAN then to a 100Mb link to the server. Interim devices are unknown.

Thx

This is quite inefficient. If you are running ethernet, you will want your mss to be equivalent to what ethernet can handle. Larger packets handle more payload, thus creating less packet in the network, less packet in the network means more available bandwidth. Packet sizes are more or less determined by the application, so setting one is not a good idea.

Thx for that

Do you know what the options mean?

How can an application set the MSS?


Love to have these questions answered ....
