To anybody:

RE: You may have tested your internet connection on websites such as DSL reports and received speeds that you feel would be adequate to host a game on Xbox Live. Well these tests use something called TCP (Transmission and Control Protocol), which is one of the many methods that computers use to communicate. Now you're thinking, why didn't they use TCP for Xbox Live?

Well this is because every time a TCP packet (Which is just another word for a message sent between clients/servers) is sent the sending machine expects to receive an acknowledgement packet in return. If this packet is not received guess what happens?

It sends yet another packet, and will continue until it received the acknowledgement packet. Then it will send a packet saying “I acknowledge your acknowledgement”. Now normal internet applications such as internet browsing, and internet relay chat will not be affected by the retransmission of packets, but online video games will be greatly affected by this.


Didn't NVEI talk about the TCP packet awhile back (probably over a year ago), I think our guy doing the thesis paper at Cambridge came up with a solution?
