碩士 === 國立交通大學 === 電信工程研究所 === 100 === During the last decade, datacenters have risen to dominate the computing landscape and become an important research topic. Among four main components of a datacenter networking architecture: physical topology, routing over topology, selection between multiple paths supplied by routing, congestion control technique on the high speed, low latency network, the last three objects in the list haven't investigated worthy. In this thesis, we propose a congestion control mechanism in cloud datacenter by bandwidth adaptation and evaluates the performance of multipath routing in its present in cloud datacenter. Both fat tree and experimental topologies are considered in the testing of performance. Simulations are conducted to compare the eeffectiveness of the proposed mechanism. The performance results demonstrate that the proposed congestion control in cloud datacenter by bandwidth adaptation can outperform the throughput, packet error rate and delay issues compare with traditional Transmission Congestion Protocol (TCP) in cloud datacenter environments.
