`12.1.  Claim 9 ................................................................................................ 39 
`12.1.1. 
`[9.P] A method for communicating information over a

`by a first processor; .............................................................. 42 
`[9.2] dividing the data into multiple segments; ................... 47 
`[9.3.1] prepending a packet header to each of the
`segments by a second processor, thereby forming a
`packet corresponding to each segment, ............................... 48 
`[9.3.2] each packet header containing a media access
`control layer header, a network layer header and a
`transport layer header, wherein the network layer
`header is Internet Protocol (IP), the transport layer
`header is Transmission Control Protocol (TCP) and ........... 52 
`[9.3.3] the media access control layer header, the
`network layer header and the transport layer header are
`prepended at one time as a sequence of bits during the
`prepending of each packet header; and ................................ 54 
`[9.4] transmitting the packets to the network. ..................... 57

`transport layer; and .............................................................. 62 
`[11.2] determining, by the second processor, whether
`the other packet corresponds to the same TCP
`connection as the transmitted packets.................................. 64 
`12.4.  Claim 12 .............................................................................................. 66 
`12.4.1.  The method of claim 9, further comprising establishing

`processor. ............................................................................. 66 
`12.5.  Claim 13 .............................................................................................. 67 
`12.5.1.  The method of claim 9, further comprising creating a

`[17.2] dividing, by a second mechanism, the block of
`data into multiple segments; ................................................ 75 
`[17.3.1] prepending, by the second mechanism, an
`outbound packet header to each of the segments,
`thereby forming an outbound packet corresponding to

`outbound media access control layer header, an
`outbound Internet Protocol (IP) header and an
`outbound TCP header, ......................................................... 77 
`[17.3.3] wherein the prepending of each outbound
`packet header occurs without an interrupt dividing the
`prepending of the outbound media access control layer
`header, the outbound (IP) header and the outbound
