Abstract

<abstract abstract-type="main" id="ett2730-abs-0001"> <title>ABSTRACT</title> <p id="ett2730-para-0001">Multimedia services, which are experiencing an enormous popularity nowadays, have been regarded as one of the main applications of Future Internet. A key supporting technology behind these services is a scalable, intelligent and effective anycast service. Present anycast solutions are either based on route‐by‐name or lookup‐by‐name, which cannot fulfill the requirements of today's services. In this paper, we first propose an anycast network architecture that combines the merits of both the <italic>route‐by‐name</italic> and <italic>lookup‐by‐name</italic> schemes, which achieves good balance between routing scalability and forwarding efficiency, allows flexible server selection, quickly adapts to network changes and maintains flow affinity. Based on this architecture, practical anycast‐based server selection algorithms are presented with joint considerations of both network condition and server load condition. The proposed algorithms are evaluated through the discrete event network simulations using OMNET++ and the INET framework. Experiment results show that efficient server selection can be achieved.
