| Summary: | 碩士 === 健行科技大學 === 資訊工程系碩士班 === 102 === Recently, the Internet Engineering Task Force designed a new Internet address architecture in which identifiers and locators are separated, the Locator Identifier Separation Protocol (LISP) to solve the problem of excessively numerous routing tables and insufficient border gateway protocol routing scalability. Currently, LISP involves centralized and distributed architectures.
In this thesis, we will develop a mechanism called a LISP-enhanced distributed handover control (LISP-EDHC) method to adopt a distributed architecture.
Specifically, in our proposed method, a service router (SR) was used as the tunnel router, enabling it to send and receive map requests and reply to messages. Subsequently, data transmission was built between the SR(New) and SR to reduce handover latency time for facilitating convergence. Simulation results showed that our proposed method required 10% to 25% less convergence time than the LISP-distributed handover control scheme (LISP-DHC).
Moreover, the proposed method can effectively reduce wireless connection latency time. Compared with other methods involving LISP mobile nodes, LISP-proxy mobile Internet Protocol, or LISP-DHC, the convergence latency of LISP-EDHC did not substantially increase because the routes involved numerous routers. Thus, the wastage of unnecessary bandwidth and the network congestion can be prevented.
