To Cross-Layer or Not: Cross-Layering vs. Strict Layering vs. No Layering. Panel Discussion

Abstract

Strict Layering= Taxonomy: + organization of complex communication system - exceptions are the rule Abstraction: + isolation of network control functions - interactions obscured Hierarchy: + few interfaces between functions - complicated interfaces - processing delays for information exchange. Cross-Layering= Cognizance of behavior of other layers: + fosters synergism between control functions + reduces redundant functionality - requires system-wide knowledge Exchange of information between arbitrary layers: + well-informed control decisions - potentially many interfaces - stability and robustness of control Integrated design of multiple layers: + tailoring for specific contexts + optimization - loss of generality - complicated implementation. No Layering= Set of control algorithms: goals, inputs, and actions open or closed loop responsiveness temporal duration and spatial extent of response interactions Retain: + modularity + well-defined interfaces Gain: + function-oriented view of communications system + flexibility of design + efficiency and simplicity of implementation.
