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 ContentOriented Pub/Sub system (COPS) to achieve an efficient pub/sub capability for CCN. COPS enhances the heretofore inherently pull-based CCN architectures proposed by integrating push based multicast 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 pub/sub content centric 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 COPS provides considerable performance improvements in terms of aggregate network load, publisher load and subscriber experience compared to that of a traditional IP infrastructure."],["dc.identifier.issn","1611-1044"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/14625"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.publisher","Institute of Computer Science, Georg-August-Universität Göttingen"],["dc.publisher.place","Göttingen"],["dc.title","COPS: An Efficient Content Oriented Publish/Subscribe System"],["dc.type","report"],["dc.type.internalPublication","yes"],["dspace.entity.type","Publication"]]

The Information Centric Networks (ICN) paradigm offers an alternative approach for reliably delivering data by naming content and exploiting data available at any intermediate point (e.g., caches). However, receivers are often heterogeneous, with widely varying receive rates. When using existing ICN congestion control mechanisms with in-sequence delivery, a particularly thorny problem of receivers going out-of-synch results in inefficiency and unfairness with heterogeneous receivers. We argue that separating reliability from congestion control leads to more scalable, efficient and fair data dissemination, and propose SAID, a control protocol for Scalable and Adaptive Information Dissemination in ICN. To maximize the amount of data transmitted at the first attempt, receivers request any next packet (ANP) of a flow instead of next-in-sequence packet, independent of the provider’s transmit rate. This allows providers to transmit at an application-efficient rate, without being limited by the slower receivers. SAID ensures reliable delivery to all receivers eventually, by cooperative repair, while preserving privacy without unduly trusting other receivers.attempt, receivers request any packet of a flow instead of next-in-sequence packet, independent from the transmitting rate of the provider.

Currently, MMORPG are built on an IP infrastructure with the primary responsibility on servers to do the work of disseminating control messages and having to predict/retrieve objects in each player's view. Limited server resources significantly impair the user's interactive experience. Modern fast-paced action games that run on a client/server architecture limit the number of players who can interact simultaneously since the server needs to handle the frequent updates and disseminate them.

To better deal with an incident, au- thorities from different services ( e.g. , fire, police) and juris- dictions need to work together in a new dynamically created team, different from their original organizational/administra- tive hierarchy. Unfortunately, existing solutions ( e.g. , IP, or traditional telephony) are not well-suited to deal with such group communication due to the dynamic binding between roles and individuals, and mobility. A significant burden is placed on administrators to just establish and maintain necessary channels, distracting them from restoring order. To make things worse, since senders do not know which in- dividual(s) to send to, information cannot reach the right people, delaying rescue efforts. We propose CNS, leveraging the benefits of ICN to pro- vide the essential communication for efficiently managing disasters. We first design a namespace enabling dynamic creation and evolution of incident related (sub-)namespaces to represent roles of first responders assigned to the disaster. This allows first responders to receive the appropriate infor- mation on a timely basis, with senders addressing the recip- ients based on their roles. Predefined namespace templates for disaster types minimize management overhead for estab- lishing communication. We also find the need for a new en- hanced forwarding rule to support such a recipient hierarchy. We have developed a prototype demonstrating feasibil- ity and efficiency. With the help of large-scale simulations and real-world disaster traces, we compare CNS with an IP- based solution.

In this paper, we propose a lightweight enhancement to content-centric pub- lish/subscribe systems for flow and congestion control as well as for reliability. R-COPSS allows the publishers to efficient- ly use the content-centric network by having subscribers gen- erate timely feedback while enabling subscribers to make use of NDN to perform local repair for reliable delivery. Rather than having all subscribers generate feedback (ACK) per packet, we seek to elect particular subscribers in a hierarchy to provide the feedback and the rest of them resort to a pe- riodical summary. Our approach not only reduces the load on the publisher, but also removes the requirement on the publisher to limit its sending rate to the slowest subscriber.
