Appeal 2007-0457
Application 10/652,267
Appellants invented a method and system for offloading Transport
Control Protocol (TCP) processing between a host and a network interface
card (NIC). Particularly, a TCP enabled Ethernet controller (TEEC)
processes an incoming packet without reassembly, and temporarily buffers
the packet in an internal elastic buffer before forwarding the packet to the
host computer. (Specification 11).
Claim 1 is illustrative of the claimed invention, and it reads as
follows:
1. A system for offloading TCP processing, the system comprising:
a host;
a network interface card (NIC) coupled to said host, said NIC
comprising, a TCP enabled Ethernet controller (TEEC), said TEEC
comprising, at least one internal elastic buffer, wherein said TEEC
processes an incoming TCP packet once and temporarily buffers at least
a portion of said incoming TCP packet in said internal elastic buffer, said
processing occurring without reassembly.
In rejecting the claims on appeal, the Examiner relied upon the
following prior art:
