A Hierarchical Mapping System for Flat Identifier to Locator Resolution Based on Active Degree

Abstract

Overloading of IP address semantics appeals for a new network architecture based on Identifier (ID)/Locator separation. The challenge of Identifier (ID)/Locator separation is how to solve the scalability and efficiency challenges of identity-to-location resolution. By analyzing the requirements of the Identifier (ID)/Locator separation protocol, this paper proposes a hierarchical mapping architecture on active-degree (HMAA). This HMAA was divided into three levels: active local level, neutral transfer level, and inert global level. Each mapping item is dynamically allocated to different levels to ensure minimizing delay according to its activity characteristics. The top layer CHORD is constructed by the Markov Decision Process, which can keep consistency between the physical topology and the logical topology. The simulation results on delay time show that HMAA can satisfy the scalability and efficiency requirements of an Identifier (ID)/Locator separation network.

IP Expiration and Host Name Mismatch: A Common Client Server Connectivity Issue

“…One solution is that client servers use a dynamic Domain Name System or dynamic DNS, which always points to the latest IP [7]. However, that would require the whitelist rules to allow for Host Name pass-throughs instead of (or in addition to) IP addresses.…”
