“…COPSS adopts a Content Descriptor (CD) based approach wherein a CD could refer to a keyword, tag, property of the content and etc. ; similar to that adopted by XTreeNet [8] and SEMANDEX [9]. RSS feeds and XMPP pub/sub [17] are used to publish frequently updated content such as news headlines, blog entries and etc.…”

Content-Centric Networks (CCN) provide substantial flexibility for users to obtain information without regard to the source of the information or its current location. Publish/ subscribe (pub/sub) systems have gained popularity in society to provide the convenience of removing the temporal dependency of the user having to indicate an interest each time he or she wants to receive a particular piece of related information. Currently, on the Internet, such pub/sub systems have been built on top of an IP-based network with the additional responsibility placed on the end-systems and servers to do the work of getting a piece of information to interested recipients. We propose Content-Oriented Pub/Sub System (COPSS) to achieve an efficient pub/sub capability for CCN. COPSS enhances the heretofore inherently pullbased CCN architectures proposed by integrating a push based multicast capability at the content-centric layer.We emulate an application that is particularly emblematic of a pub/sub environment-Twitter-but one where subscribers are interested in content (e.g., identified by keywords), rather than tweets from a particular individual. Using trace-driven simulation, we demonstrate that our architecture can achieve a scalable and efficient content centric pub/sub network. The simulator is parameterized using the results of careful microbenchmarking of the open source CCN implementation and of standard IP based forwarding. Our evaluations show that COPSS provides considerable performance improvements in terms of aggregate network load, publisher load and subscriber experience compared to that of a traditional IP infrastructure.

“…• COPSS supports the notion of Content Descriptor (CD) [8,9] based publishing and subscription. A CD goes beyond name-based [3] and topic-based [10] content identification and allows for contextual identification of information and supports ontologies and hierarchies in specifying interests.…”

“…The approach leverages existing data stores, without requiring redesign, or relocation, of data sources, and can integrate information from multiple sources located anywhere within the network. Over the last six years at Semandex we have developed a variety of semantic network products based on our patented XML-based semantic multicast technology [13]. The technology provides a "true" network platform that uses an overlay XML-based content routing (much like IP routing, but at layer 7), not just peer-to-peer communications, to distribute information.…”

Rapid and slow onset disasters require coordination between emergency responder and public health organizations. During a disaster many organizations are involved in the delivery of emergency services: emergency medical services (EMS), the fire and police departments, hospitals, public health officials, local authorities, etc. Resource planning, logistic coordination, and information sharing among all these units is therefore very important to save lives and reduce costs. To satisfy these needs, through grants from the National Library of Medicine, Semandex Networks is building the Medical Emergency Disaster Response Network (MEDRN). MEDRN uses Semantic Network technology to facilitate the access, dissemination and sharing of information across all parties involved in emergency management. The technology is currently fielded by SPAWAR, the Marine Corps and other Department of Defense (DoD) and non DoD national security agencies. INTRODUCTIONThe need for effective information networks for disaster prevention, response and recovery is strikingly clear. One only needs to look at recent disasters to understand this: Hurricane Katrina, which caused over 1,800 deaths [1], the December 2004 tsunami, which killed over 280 thousand

“…For the purpose of information discovery and flexible querying, we abstract information as collections of data items, where each data item is described by a set of content descriptors (CDs). CDs are an abstraction of keywords, terms, or other atomic information units [30]. For instance, in information retrieval applications, data items are text documents, and the CDs are the terms appearing in them.…”

We propose a novel privacy-preserving distributed infrastructure in which data resides only with the publishers owning it. The infrastructure disseminates user queries to publishers, who answer them at their own discretion. The infrastructure enforces a publisher kanonymity guarantee, which prevents leakage of information about which publishers are capable of answering a certain query. Given the virtual nature of the global data collection, we study the challenging problem of efficiently locating publishers in the community that contain data items matching a specified query. We propose a distributed index structure, UQDT, that is organized as a union of Query Dissemination Trees (QDTs), and realized on an overlay (i.e., logical) network infrastructure. Each QDT has data publishers as its leaf nodes, and overlay network nodes as its internal nodes; each internal node routes queries to publishers, based on a summary of the data advertised by publishers in its subtrees. We experimentally evaluate design tradeoffs, and demonstrate that UQDT can maximize throughput by preventing any overlay network node from becoming a bottleneck.
