Content Centric Networking (CCN) is a new paradigm in networking and a future Internet architecture. Performance evaluations show that conventional CCN forwarding strategies which use replication of Interests (standard) or the shortest path (best-face) do not perform well under high bandwidth requirements and loaded networks. We have designed and evaluated(More)
The Ad hoc On-Demand Distance Vector (AODV) routing protocol is designed for use in mobile ad-hoc networks. As of the writing of this article, there exist several implementations of the AODV protocol for a range of operating different techniques and programming languages. This paper describes the architecture of 2 AODV implementations and experimentally(More)
Content Centric Networking (CCN) is an evolving paradigm in networking where communications are based on named content rather than the named hosts model of today's networks. Though CCN is capable of multi-path communications by design, no work has been done to characterise multi-path content transfers in CCN with an analytical model. In this work, we have(More)
Force (IETF). PMIPv6 is a protocol that uses the same concepts as used in Mobile IPv6 (MIPv6), but modified to operate in the network part only instead of involving the Mobile Node (MN) as well. PMPv6 is claimed to posses a number of advantages over the host based mobility management protocols in use today, above all MIPv6. The main advantage of using(More)
Network virtualization is a concept where physical resources are used to create virtual resources that are combined to form virtual networks. As one of the key enablers of the future Internet, network virtualization solves a number of issues associated with today's networks. Concepts of network virtualization that are not restricted to virtualization(More)
A routine culture of the internal surfaces of a laboratory pressure pot was performed. Candida albicans, Pseudomonas sp., and an unidentified gram-negative rod were isolated. Disposable plastic bags filled with water were used as a barrier to cross contamination during polymerization of repair acrylic resin in a pressure pot. No leakage of plastic bags(More)
