Research And Implementation Of Identifier-locator Separation Mapping Function At NeoKylin Platform

With the rapid development of information technology, the traditional Internet network continues to expand, more and more complex scenarios appear, which leading to series of problems in aspects of network security, routing scalability and mobility, etc. To solve these issues caused by the dual attributes which are the identity attributes and location attributes of the IP address, identity and location separation mechanism came into being. Universal Identifier Network adoptes a new network architecture and theory which separate the identity attributes and the location attribute of the IP address. The address space is divided into the access network space and the core network space. This network defines two types of identification:access identification and exchanging routing identification to support routing scalability, mobility and protect core network security, users’location privacy and so on.Kylin Operation System is a Chinese self-developed operation system which is divided into server operating system and individual host platform. This article aims at achieving the mapping system of Identifier-locator Separation Network on the total localized platform (64-bits loongson+NeoKylin), so that the Identifier-locator Separation Network and localized software and hardware can be combined together.Firstly, the basic system and communication processes of Universal Identifier Network are described and the importance to achieve the system at Kylin platform is explained. On this basis, Identifier-locator Separation Mapping module at Kylin platform is designed in detail that each sub-module is described specificly. Respectively, the kernel and user levels are designed functional, focusing on the 128 large dynamic routing pool, User interaction module, the kernel switch design, mapping cache table, complex mapping support and other key issues. This essay has the following characteristics:Achieving identify separate mapping system function at Kylin operating system platform. The route identifier is 128 bits so that the network supports both 32 bits and 128 bits of the access terminals. This network supports complex mapping function. By using the command structure in vtysh of quagga software, configuration management is quite simple.Finally, in accordance with the overall design of the system to achieve each module, key technologies in each module are described in detail.At the end, Identifier-locator Separation Mapping module at Kylin platform is tested. The results show the system’s various functions meet the design goals. Finally, conclusion is drew and some suggestions are given for future work.
