The Processing Workload Evaluation in two Network Management Models of IP Networks

As the work for managing a whole network effectively without a limited purpose, there is the work of PBNM (Policy-based network management). PBNM has two structural problems such as communication concentration from many clients to a communication control mechanism called PEP (Policy Enhancement Point) and the necessity of the network system updating at the time of introducing PBNM into LAN. Moreover, user support problems in campus-like computer networks such as trouble user support at updating a client’s setups and coping with annoying communication cannot be improved by PBNM. To improve these problems, we show a next generation PBNM called it DACS (Destination Addressing Control System) Scheme which overcomes theses problems and has the function which does not exist in existing PBNM. However, when DACS Scheme is used in real networks, the processing load of communication control can be heavy with respect to standard mechanisms of other schemes. About this point, we show and evaluate two network management models: 1) INfrastructure-based Management (INM) model for PBNM, and 2) Client Management (CM) model for DACS Scheme. Finally, we show the fact that that CM model as DACS Scheme is an advantageous with respect to INM model at the point of processing load.
