Abstract
A system and method are provided for controlling packet header information in a packet communications switch fabric. The method comprises: programming the cell header overhead (OH) field definitions; accepting a packet including a plurality of cells and corresponding cell headers, each cell header including a plurality of overhead fields; defining the cell header OH fields; and, transmitting the packet. Defining the cell header OH fields includes defining cell header OH field location, position, meaning, structure, and length. In other aspects, the method comprises redefining the cell header overhead fields, once they are accepted. For example, the OH field information can be modified, relocated, or an OH field can be added to the cell header. In yet other aspects, the OH field information can be extracted and/or reformatted.
