In the Identifier Locator Network Protocol (ILNP) networks, the existing mobility control schemes based on the centralized entity, called the Dynamic Domain Name Service (DDNS) server, such that all the control traffic is processed at the DDNS server. However, the centralized mobility schemes have significant limitations, such as control traffic overhead at the server and large handover delay. In order to resolve these issues, we propose a new mobility control scheme for ILNP networks, which manages the identifier-locators (ID-LOCs) in the fully distributed manner. In our scheme, each domain has a dedicated mobile DDNS (m-DDNS) server at the site border router (SBR). The m-DDNS server maintains two databases; i.e., home host register (HHR) and visiting host register (VHR), to support the roaming of mobile hosts. When a mobile host roams into a domain, the m-DDNS server in the visiting domain registers the host’s ID-LOC in the VHR and requests the update of HHR to the m-DDNS server in the home domain. Since the m-DDNS servers communicate each other directly, the ID-LOC mappings are managed without involvement of any central entities. We analyzed our proposed mobility scheme via numerical analysis and compared its performance with those of existing schemes. Numerical results showed that our scheme outperforms the existing mobility control schemes substantially in terms of control traffic overhead at the servers, total transmission delay and handover delay.

“…To overcome these problems, we propose a distributed mobility control of EID‐local locator (LLOC) mappings in the LISP‐based mobile networks. In the proposed scheme, a host is uniquely identified by a hierarchical 128‐bit EID structure, which contains the information of the home domain that the host was subscribed to. By this, the access router (AR) will check whether the EID belongs to its domain (nonroaming case) or not (roaming case).…”

A hash‐based distributed mapping control scheme in mobile locator‐identifier separation protocol networks

In the locator-identifier separation protocol (LISP), the existing mapping control scheme is based on a centralized approach, in which a map server is used as a mobility anchor for mobile hosts. However, such a centralized scheme has some limitations that include traffic overhead at the central map server, service degradation by a single point of failure, and large data transmission delay. In this article, we propose a new hash-based distributed mapping control scheme of endpoint identifier (EID) and local locator in the LISP-based mobile networks. In the proposed scheme, each access router in the mobile network has a distributed local map server. For a mobile host, a distributed local map server is designated to manage the associated EID-local locator mapping by using a hash function. For roaming support, each gateway has a distributed global map server, which maintains visiting EID-locator register. From the numerical results, we see that the proposed scheme can reduce the amount of control traffic at the map server and total signaling delay compared to the existing mapping control schemes.
