SCALABLE AND EFFICIENT TECHNIQUES FOR NETWORK MANAGEMENT AND NETWORK SIMULATION

摘要: This work consists of two parts both which are based on the SSFNet simulator and its extensions. The first part describes DOORs, is a distributed framework for network management middleware. goal to easily distribute functional agents locations where they may carry actions application closer managed node. In large networks with multiple managers, problems in usually draw attention traffic problem location. added only exaggerates problem. We show quantify benefits proposed distribution by implementing several real-time managers using our framework. also propose describe techniques, including congestion control parameter optimization, use second Genesis, decomposition. Genesis combines simulation modeling single execution. It decomposes into parts, called domains, time intervals, simulates each partition independently concurrently over one interval. After interval, information exchanged domain simulators. Each will model external own flow data received from other domains. Domain simulators iterate same interval until reach global convergence controllable precision. Thus, more scalable alternative demand huge memory resources simulate topologies. distributes amongst various machines thus approach simulation.
