Algorithms and Contracts for Network and Systems Management.
Paulo Rogério Pereira, Paulo Pinto · 1999
Most current management applications provide a rather low-level view of the managed systems, have limited operations automation, usually forcing the manager to work at MIB variable level. To solve these problems, an approach based on a hierarchy of management algorithms for the different abstraction layers is used in this paper to manage a company's business processes. An example is described to illustrate how the top-level management requirements are refined down to the equipment level, formalized in contracts enforced by the algorithms and monitored by management QoS parameters offered by the algorithms. 1. Introduction The main task of a network manager is offering the end users the best possible service from the network with the minimum cost. As networks grow in number, dimension, complexity, dynamism and equipment variety, network management and control is becoming a non-trivial task, and the amount of effort dedicated to manage a network and its systems is substantial. ...
