Interconnection network plays an important role in massively parallel systems. As a high performance switched network standard, Infiniband is widely used in MPP systems. Compared to fat-tree topology which is commonly used in Infiniband networks, mesh/torus topology can achieve better performance and scalability. This paper proposes an Infiniband-based multi-path mesh/torus interconnection network...
An alarming trend for the global routing table's growth factor in the interdomain IP backbone shows that Internet inter-domain routing scalability becomes an issue again. It is widely agreed upon that the rapid global routing table size growth is mainly due to the growth in the number of ASs and the wide deployments of multihoming and traffic engineering. These popular commercial practices deaggregate...
Unlike other efforts on supporting triples of higher orders of magnitude in a centralized triplestore, we believe, as the semantic Web evolves, the unstructured P2P paradigm may better fit with the application scenario of triplestores used by individuals in the future. We designed an unstructured P2P RDF triplestore, focusing on its efficient query routing mechanism, and demonstrated that it can deliver...
It has been widely recognized that the current Internet routing system is facing serious scaling problem. Several efforts argue that the routing scaling problem necessitates architectural changes. In this paper, we propose a scalable routing architecture for future Internet. Our proposal goes along the ideas of inter-domain/intra-domain routing separation and provider/customer networks separation,...
MILSA (Mobility and Multihoming supporting Identifier Locator Split Architecture) is a new architecture to address the naming, addressing, and routing challenges in the current Internet. It separates the identifier (ID) from locator, separates control from data delivery, and provides comprehensive benefits in routing scalability, mobility and multihoming, traffic engineering, renumbering, and policy...
It has been recognized that today's Internet routing and addressing system is facing serious scalability problems. The ever increasing network customers, multihoming, and traffic engineering, are driving the growth of Default Free Zone routing table size at an alarming rate. To solve this issue, several solutions have been proposed to separate the current single numbering space, i.e., the "IP...
Aiming to the problem of scalability caused by frequent route updates in current inter-domain routing system, this paper proposes a scalable inter-domain routing update mechanism to restrict the propagating scope of the update, called SIRUM. The autonomous system estimates the probability of that the communications of its neighbors are affected by the update according to the history information of...
By building a P2P content distribution network (CDN), peers collaborate to distribute the content of underprovisionned Websites and to serve queries for larger audiences on behalf of the Websites. This can reveal very challenging, given the highly dynamic and autonomous participation of peers. Indeed, the P2P-CDN should adapt to increasing numbers of participants and provide robust algorithms under...
Especially for large Network Operators (NOs), eliminating routing anomalies is an important aspect for the internal BGP design. To avoid such unwanted effects, classical architectures have need of certain restrictions kept in both, the network design and the iBGP peering. However, these restrictions are in conflict with the optimized network designs NOs seek. In this study we develop an inherently...
The Chord is a famous peer-to-peer application. There are many variants which change the structure and the routing algorithm of the Chord, and all these variants achieve the higher routing efficiency than those of the original ones. To improve the routing efficiency of base-k Chord, this paper proposes a new finger table for base-k Chord by using symmetrical bidirectional structure, which just like...
Among the problems faced when developing support for M2M applications are the vast differences in the capabilities of different devices, as well as the requirements for scalability and flexibility. In this paper we show solutions to these problems by defining a service platform architecture for connected objects. The architecture exhibits a number of features to support generality, adaptability, scalability,...
To resolve the scalability problem in the existing Internet, there are many researches proposing the idea of separating the Internet into two independent evolving spaces, the access network and the core network, respectively. Such separation provides us opportunities to reconsider the methods of implementation of inter-domain traffic engineering under the new network environment. Based on the existing...
Although benefits comes with decoupling IP dual roles, overload in routers or reallocate a new addressing space for inter-domain routing system is still a great challenge. In this paper, we use the idea of Locator/ID separation but redesign the topological locator to construct a scalable and universal core which can integrate heterogeneous access networks. Moreover, the coarse-grained multipath inter-domain...
Resource discovery is critical to the usability and accessibility of grid computing systems. Distributed hash table (DHT) has been applied to grid systems as a distributed mechanism for providing scalable range-query and multiattribute resource discovery. Multi-DHT-based approaches depend on multiple DHT networks with each network responsible for a single attribute. Single-DHT-based approaches keep...
A reliable storage system is a system that ensures the protection of data from loss. Such systems are needed in many critical fields. We cannot imagine that a financial institution looses data about one its clients. Moreover the exponential growing volumes of the data and its availability are crucial issues. A centralized storage system would be overloaded and be a single point of failure. That is...
Although benefit comes with multipath routing, large deployment in todaypsilas Internet seems elusive. Decoupling IP dual roles could improve the scalability of routing systems which gives some light on multipath inter-domain routing, but overload in routers or reallocate new routing identifier is still a great challenge. In this paper, we inherit the decoupling idea but subdivide the topological...
The main architectural problem with the current inter-domain routing model is the overloading of IP addresses due to their use for identification, location, and forwarding. This makes it hard to support the need for multi-homing, traffic engineering, and mobility while maintaining address hierarchy that is essential for scalable routing. Thus, there is a need to separate identifiers from locators...
The Internet has become a vast and complex infrastructure. One of the aspects of deeper concern in the community is routing scalability, which involves both the size and dynamics of the global Internet routing table. Many future Internet initiatives stand for ldquoclean slaterdquo or disruptive approaches to overcome this issue; nevertheless, network operators need evolutionary solutions. In this...
We envision an information-centric future Internet where the network is built around named pieces of data instead of explicitly addressable hosts. One clear way of implementing information-centric networking is using publish and subscribe (pub/sub) operations instead of the send and receive primitives. Internet-like pub/sub networking requires completely different routing protocols and forwarding...
In wireless sensor and actuator networks nodes can fail and the link quality can fluctuate rapidly over time. With the start of the pervasive revolution, issues like scalability and mobility must be tackled in these low-power and lossy networks. We propose and evaluate two mechanisms, path resumption and cost based multipath routing, which can help existing or new local path recovery techniques to...
