摘　　要：Publish/subscribe(pub/sub) paradigm is the main communication model for Information-Centric Network(ICN) proposals.A key issue for pub/sub system is how to route the content objects to the correct subscribers,and ICN is no exception.ICN network would be divided into core domain and many edge domains as today's internet does.HHR(Hierarchy Hybrid Routing scheme) is presented for ICN:A Chord-like routing scheme is used in core domain,while edge domains routing structure can be classified into three categories,Local Routing(LR),Delivery of Local Publication to Core domain(DLPC),and Remote Publication Routing into edge domain(RPR).LR can be decided by each edge domain,which determined by many factors,such as locality characteristic for pub/sub information and local policies.A hierarchical routing algorithm is proposed to solve DLPC and RPR simultaneously.Simulation results demonstrate that HHR can be fast deployed,and can be applied in large scale network or dynamic subscription environment.Publish/subscribe （pub/sub） para- digm is the main communication model for Information-Centric Network （ICN） proposals. A key issue for pub/sub system is how to route the content objects to the correct subscrib- ers, and ICN is no exception. ICN network would be divided into core domain and many edge domains as today＇s internet does. HHR （Hierarchy Hybrid Routing scheme） is pre- sented for ICN： A Chord-like routing scheme is used in core domain, while edge domains routing structure can be classified into three categories, Local Routing （LR）, Delivery of Local Publication to Core domain （DLPC）, and Remote Publication Routing into edge domain （RPR）. LR can be decided by each edge domain, which determined by many fac- tors, such as locality characteristic for pub/sub information and local policies. A hierarchical routing algorithm is proposed to solve DLPC and RPR simultaneously. Simulation results demonstrate that HHR can be fast deployed, and can be applied in large scale network or dynamic subscription environment.
