Abstract: Provided are techniques for processing a data segment by stripping a header from a transport layer segment, performing protocol data unit detection to determine data for a protocol segment that is part of the transport layer segment data, and performing marker validation and stripping.

Abstract: Provided are techniques for processing a data segment by stripping a header from a transport layer segment, performing protocol data unit detection to determine data for a protocol segment that is part of the transport layer segment data, and performing marker validation and stripping. Also provided are techniques for processing a data segment in which a header portion of a protocol data unit is received. A number of bytes of data to be stored in an application space is determined using the received header portion. Also, a next header portion of a next protocol data unit is determined using the received header portion. Then, a peek command is issued to obtain the next header portion. Additionally provided are techniques for performing cyclic redundancy checks using a stored partial cyclic redundancy check digest and residual data.

Abstract: A method and apparatus for reestablishing secured communication after a desynchronization event. Secured communication is established between a first device and a second device using synchronized device dependent sequence values. A security sequence value from the first device is stored, preferably on a nonvolatile medium. After a desynchronization event, the first device sends the stored security sequence value to the second device as a resynchronization request. The second device returns the stored security sequence value as security assurance, preferably with a security sequence value from the second device for resynchronization.
