Design and Implementation of Mapping Systems for an ID/Locator Split Protocol for New Generation Network

We are proposing Z Network Protocol (ZNP) as a network layer protocol based on ID/Locator split approach in the future Internet. ZNP is designed to satisfy the following requirements in terms of practical operation: (1) support of L3 protocol heterogeneity, (2) scalability of ID/Locator mapping system, (3) independence of mapping information management, and (4) avoidance of locator leakage beyond the administrative boundary. This paper proposes the mapping systems of ZNP; the Name Mapping System (NMS) and the ID Mapping System (IMS). To satisfy (1), the IMS is designed to be able to manipulate variable types of locators. To satisfy (2) and (3), the NMS and the IMS compose tree structure and the mapping information of a node is managed by the mapping agents in the domain to which the node belongs. To satisfy (4), ZNP introduces the localized mapping agents. To manipulate our proposing mapping systems, we designed and implemented Z Control Message Protocol (ZCMP) as an application layer protocol. The measured signaling overhead shows that the proposing mapping systems are practical for the future Internet.
