Abstract
A system and method are provided for communicating data in a network utilizing a transport offload engine. Included is a data list object that describes how data communicated in a network is to be stored (i.e. placed, etc.) in memory (i.e. application memory). Stored in association (i.e. located, kept together, etc.) with the data list object is a sequence object. Such sequence object identifies a sequence space associated with the data to be stored using the data list object. To this end, the sequence object is used by a transport offload engine to determine whether or not incoming data is to be stored using the data list object.
Claims32
A data structure embodied on a tangible computer readable medium for use in association with a transport offload engine, comprising:
- a data list object that describes how data communicated in a network is stored in memory;
- and
- a sequence object stored in association with the data list object, the sequence object for identifying a sequence space associated with the data to be stored using the data list object;
- wherein the sequence object is used by a transport offload engine to determine whether incoming data is to be stored using the data list object;
- wherein the sequence object is kept as a tag together with the data list object in order to form a tagged data list object;
- wherein the sequence object includes a sequence object number that identifies a point in the sequence space and a sequence object length that identifies a length of the sequence space, and wherein the data structure is utilized such that it is determined whether the incoming data is in the sequence space associated with the data list object by determining whether a data sequence number falls within the sequence space as defined by the sequence object number and the sequence object length.
