Abstract—This paper presents a detailed description of content delivery techniques used in the proposed MobilityFirst (MF) clean-slate future Internet architecture now under development. The MF architecture addresses the requirements of mobile content delivery using the following basic design elements: (1). mapping of human readable names to “flat ” globally unique identifiers (GUID’s) which are used as the basis for all communication services; (2). a global name resolution service (GNRS) for dynamic binding of GUIDs to network locators; and (3). a hopby-hop storage-aware transport scheme that exploits in-network storage and copes with characteristics of wireless medium. Technical details for content naming and addressing are given, along with an explanation of methods for publishing, locating and delivering content within this framework. It is shown that the architecture supports seamless migration of content, efficient retrieval and support for optional in-network caching. Ongoing work on a real-time prototype implemented on the ORBIT testbed and the GENI experimental network is also presented. I.

Abstract—One of the crucial building blocks for Information Centric Networking (ICN) is a name based routing scheme that can route directly on content names instead of IP addresses. However, moving the address space from IP addresses to content names brings scalability issues to a whole new level, due to two reasons. First, name aggregation is not as trivial a task as the IP address aggregation in BGP routing. Second, the number of ad-dressable contents in the Internet is several orders of magnitude higher than the number of IP addresses. With the current size of the Internet, name based, anycast routing is very challenging specially when routing efficiency is of prime importance. We propose a novel name-based routing scheme (αRoute) for ICN that offers efficient bandwidth usage, guaranteed content lookup and scalable routing table size. I.

Current internet is incompetent and inept for the current trends of communication. The architecture of current internet was drafted almost 40 years ago and it is unable to cop up the problems aroused in context of security, mobility, robustness, congested traffic and vice versa of this millennium. In this paper, publish–subscribe internet routing paradigm (PSIRP) a reengineered architecture of internet is comprehensively studied, which will resolve many of the problems faced by the internet today. Keeping in view the importance of information/data, the reengineered architecture of PSIRP proffers the information–centric communication instead of host–centric communication, in response to which many of the problems of current internet will be resolved automatically. As major portion of internet is publish/subscribe in nature so PSIRP can provide a flexible, efficient and powerful architecture for future internet network design. Keyword:

Information Centric Networking (ICN) has shown possibili-ties to solve several problems of the Internet. At the same time, some problems need to be tackled in order to advance this promising architecture. In this paper we address two of the problems, namely routing and content caching. For the routing, we introduce the Potential Based Routing (PBR) to achieve several design goals such as availability, adapt-ability, diversity, and robustness. In addition, we exam-ine the performance of a random caching policy which can be a promising candidate for ICN. The integrated system which combines the PBR and a caching policy is named the Cache Aware Target idenTification (CATT). Simulation re-sults demonstrate that the PBR with replications located on less than 1 % of total nodes can achieve a near optimal rout-ing performance (close to the shortest path routing) even though a request message is randomly forwarded.

We review the main challenges and survey promising techniques for network interconnection in the Internet of the future. To this end, we first discuss the shortcomings of the Internet’s current model. Among them, many are consequence of unforeseen demands on the original Internet design such as: mobility, multihoming, multipath, and network scalability. These challenges have attracted significant research efforts in the latest years because of both their relevance and complexity. In this survey, for the sake of completeness, we cover several new protocols for network interconnection spanning both incremental deployments (evolutionary approach) and radical proposals to redesign the Internet from scratch (clean-slate approach). We focus on specific proposals for future internetworking such as: Loc/ID split, flat routing, network mobility, multipath and content-based routing, path programmability, and Internet scalability. Although there is no consensus on the future internetworking approach, requirements such as security, scalability, and incremental deployment are often considered.
