Abstract
The protocol of the present invention includes two new first level protocols and several embodiments of a second level protocol. The two new first level protocols of the present invention include the TCP2B protocol and the TCP2E protocol. In the TCP2B protocol, both client and server indicate their support for this protocol using one or more bits in TCP header. According to the TCP2B protocol, the client retransmits its requested options in the ACK message so the server need not store the options after the connection request. In the TCP2E protocol, the server maintains a Friends Table listing addresses of device recently observed to be complying with TCP. If a client's address is on the Friends Table, the connection request is processed according to TCP. Otherwise, the server sends an ACK message to the client to prompt the client to send a reset message. The client's address can then be added to the Friends Table.
