1. A system for effectuating at least one protocol layer of a protocol stack operable to implement a high speed communication link at a network node, comprising:

  • an input event structure including at least a service access point (SAP) and a connection identifier (CID) associated with a protocol layer service involving a select service user layer and service provider layer combination for a particular connection link;

    a context switch and controller block operable to retrieve latest state-specific context information from a context storage area based on said SAP and CID; and

    a generic state logic program structure operable to process at least a portion of said input event structure based on said latest state-specific context information to generate next-state context information and at least an output event vector including at least one SAP and at least one CID associated with a select destination point to which said next-state context information is to be routed, wherein said next-state context information is operable to be stored in said context storage area based on a storage SAP and CID provided in said input event structure.
