Best Effort Traffic Management Solution for Server and Agent-Based Active Network Management (SAAM).

摘要

Server and Agent-based Active Network Management (SAAM) is a promising network management solution for the Internet of tomorrow, 'Next Generation Internet (NGI)'. SAAM is a new network architecture that incorporates many of the latest features of Internet technologies. The primary purpose of SAAM is managing network quality of service (QoS) to support the resource- intensive next-generation Internet applications. Best effort (BE) traffic will continue to exist in the era of NGI. Thus SAAM must be able to manage such traffic. In this thesis, we propose a solution for management of BE traffic within SAAM. With SAAM, it is possible to make a 'better best effort' in routing BE packets. Currently, routers handle BE traffic based solely on local information or from information obtained by link-state flooding which may not be reliable. In contrast, SAAM centralizes management at a server where better (more optimal) decisions can be made. SAAM's servers have access to accurate topology and timely traffic-condition information. Additionally, due to their placement on high-end routers or dedicated machines, the servers can better afford computationally intensive routing solutions. It is these characteristics that are exploited by the solution design and implementation of this thesis.
