Research And Implementation On Congestion Control In IP Network

As an information society, with internet expanding, all kinds of application increasing rapidly, the congestion of network has been a hot issue which studied a lot, in current network communication field.This thesis contains following contents:1. Describes the Network Congestion, Routing Protocol, TCP, UDP's basic idea and their principles. Also introduces some new TCP improving congestion arithmetic.2. Introduces current situation of QoS researching and application, as well as a lot of CISCO QoS function.3. Design and build up a congestion network topology regarding to the mind of network congestion and the equipment of the lab. Design several experiments based on TCP, UDP, TCP&UDP. Record the data, and use this data to analyze the phenomena, and explain its principle.4. Aim at a real network architecture, base on CISCO data classifying, congestion management and avoidance, QoS guarantee mechanism, provide a data prioritization control strategy, re-arrange, re-integrate network architecture, and resource, compare and analyze between before and after the experiment data, obtain a referenced scheme and practical instruction, which can be applied into a similar QoS implemented network environment, can be used for managing network resource dynamically, improving network utilization efficiency.
