Manageability of the Internet: Management with new functionality

The current Internet, while successful in many aspects, has a set of associated architectural and business problems. This article discusses problems of the Internet and presents challenges of the future Internet, with a particular focus on manageability. This paper advocates that the data, control, and management planes should be separated; this provides more granular path control selection for traffic differentiation, load balancing, and other issues. We perform experiments based on an exemplar monitoring scenario, comparing the benefits of path control resulting from plane separation to current network monitoring methods. ��2010 IEEE
