DESIGN OF ASYMMETRIC MULTI-CHANNEL ROUTER FOR HETEROGENEOUS TRAFFIC
MetadataShow full item record
With the spread of the cloud-computing today, local networks have been gradually developed to have better support for cloud applications. For a specific sub-network, different ports may have different requirements. Traditional symmetric router assumes uniformed resource distribution among all ports, overestimating resources needed at some ports. This thesis proposes an innovative Asymmetric Multi-Channel edge router, which supports non-uniformed port distribution based on the clients’ demand. In this work, the concept of Asymmetric Multi-Channel (AMC) router is introduced, and the architecture of the AMC router is designed. In order to verify the cost saving of the proposed router, a general cost model is developed to provide cost comparison between the traditional symmetric router and the proposed AMC router. A reconfigurable scheduling scheme is proposed, which can achieve constant-time (O(1)) performance with the introduction of pipeline paralleled comparators and updaters. A configuration strategy is proposed for the most suitable resource distribution.
