“…We chose Squid as a basic platform for its robustness and wide spread usage. Moreover, as Squid can support many cooperation mechanisms, such as Internet Cache Protocol [32] and Cache Digests [25], the multi-version cooperative lookup can be implemented by modifying the existing code instead of writing it from scratch. Since our intermediary node can operate not only singularly, but also in a cooperative way on the basis of a hierarchical or flat distributed cooperation scheme, its behavior has been modified both at the single node level and at the cooperation level.…”

“…When a node experiences a local miss, the remote lookup starts with the location component of the local node issuing query messages for the requested resource to the location component on the other nodes in order to locate either the exact or a useful version of the requested resource. The most important query-based protocol is ICP, defined in [32] and implemented in Squid [31]. For this reason, we used ICP as the basic protocol for query-based cooperation.…”

The overwhelming popularity of Internet and the technology advancements have determined the diffusion of many different Web-enabled devices. In such an heterogeneous client environment, efficient content adaptation and delivery services are becoming a major requirement for the new Internet service infrastructure. In this paper we describe intermediary-based architectures that provide adaptation and delivery of Web content to different user terminals. We present the design of a Squid-based prototype that carries out the adaptation of Web images and combines such a functionality with the caching of multiple versions of the same resource. We also investigate how to provide some form of cooperation among the nodes of the intermediary infrastructure, with the goal to evaluate to what extent the cooperation in discovering, adapting, and delivering Web resources can improve the user-perceived performance.

“…The most popular synchronization and replication protocols are the Internet Cache Protocol (ICP) [22], Cache Digest, CARP (Cisco) [23], WCCP (Microsoft), Flood-d [24], LDUP [25] and SCSP. SCSP uses a request-reply paradigm implemented independently of the transport protocol.…”

Abstract-Ad Hoc networking is a rather old technology that is gaining a lot of momentum in the research community. It is still an area under development and there are several proposals for the technology regarding routing protocols, addressing, interoperability, etc. Because of the extreme conditions where Ad Hoc networks should operate, it is envisioned that in medium to large scale networks, a hybrid proactive and reactive routing mechanism should be used. Therefore, considering the proactive routing protocols as the most suitable protocol for certain topologies in Ad Hoc networks, this paper proposes a specific layered structure to enable both technologies in a seamless manner. This approach supports both reactive (e.g. AODV, DSR) and proactive link state (e.g. OLSP) protocols. The proposed layered structure divides the routing problem into different parts, where one module performs the routing algorithm, another module takes care of replicating and synchronizing the routing tables, and a third one evaluates the routing information for triggering hand-over signals to the upper layers. The overall responsibility for selecting the appropriate routing schema and for initiating the roaming process resides on a proposed Context Sensitive Roaming Layer. This paper describes the interface and the functions implemented by the Roaming Layer. The paper also analyses replication using the Server Cache Synchronization Protocol (SCSP). Finally, the last part of the paper describes the demand for Ad Hoc networks, which is driven by applications supported with an appropriate billing or bonus mechanism.
