【Abstract】 Host- centric Internet no longer satisfies the increasing demand for highly scalable and efficient content distribution and retrieval. Recognizing this,a number of Future Internet research projects propose the concept of Information- Centric Network( ICN).In ICN,anycast plays an important role and is even regarded as a primary network primitive in some architecture such as DONA and SCAFFOLD. In this paper,we propose a novel anycast routing scheme based on ID /LOC separation. The edge network utilizes local identifiers to achieve routing and anycast is realized by route- by- name,whereas the routing in the core network is realized by global locators and lookup- by- name anycast is used. Based on this architecture,practical anycast- based server selection algorithms are presented. The results show that the proposed anycast routing architecture based on ID /LOC separation can combine the advantages of route- by- name anycast with lookup- by- name anycast.更多还原
