This paper presents a mesh with virtual buses as the bandwidth-efficient implementation of the mesh with multiple broadcasting on which many computational problems can be solved with reduced time complexity. The new system provides a low latency and high bandwidth communication mechanism without the disadvantage of the dual network approach: the possible bandwidth waste. The virtual buses are b...

Tor is a primary tool for maintaining anonymity online. It provides a low-latency, circuit-based, bidirectional secure channel between two parties through a network of onion routers, with the aim of obscuring exactly who is talking to whom, even to adversaries controlling part of the network. Tor relies heavily on cryptographic techniques, yet its onion encryption scheme is susceptible to taggi...

We present the design and evaluation of a predictable Network-on-Chip (NoC) to interconnect processing units running multimedia applications with variable-bit-rate. The design is based on a connectionless strategy in which flits from different communication flows are interleaved in the same communication channel between routers. Each flit carries routing information used by routers to perform a...

In this paper we propose to support symmetric bidirectional route optimization in mobile IPv4 considering ingress-filtering routers. We developed subnet-based direct tunneling techniques to improve the routing efficiency for mobile IP and a binding optimization technique to reduce the handoff latency for mobile nodes. An enhanced correspondent agent was introduced to collaborate with the home a...

Named-Data Networking (NDN) is a candidate next-generation Internet architecture designed to address some limitations of the current IP-based Internet. NDN uses the pull model for content distribution, whereby content is first explicitly requested before being delivered. Efficiency is obtained via routerbased aggregation of closely spaced requests for popular content and content caching in rout...

The cost of high-performance parallel platforms prevents parallel processing techniques from spreading in present applications. Networks of Workstations (NOW) exploiting oo-the-shelf communication hardware, high-end PCs and standard communication software provide much cheaper but poorly performing parallel platforms. In our NOW prototype called GAMMA (Genoa Active Message MAchine) every node is...

Vehicular Ad-hoc Network (VANET) is a growing technology. The vehicle (acting as mobile routers) in the network uses the wireless medium to communicate with other nodes (vehicles) in their radio range. A heterogeneous wireless network (HWN) which is hybrid network of cellular network (having access routers (AR) and Internet Service Providers (ISP) for providing communication and internet servic...

Traditionally, Internet routers only perform best effort service by processing each incoming packet in the same manner. With the emergence of new applications, packet classification is essential for supporting advanced Internet applications, such as network security and QoS provisioning. As the packet classification on multiple-fields is a difficult and time consuming problem, Internet routers ...

Latency has become an important metric for network monitoring since the emergence of new latency-sensitive applications (e.g., algorithmic trading and high-performance computing). To satisfy the need, researchers have proposed new architectures such as LDA and RLI that can provide finegrained latency measurements. However, these architectures are fundamentally ossified in their design as they a...

Tor is a real-world, circuit-based low-latency anonymous communication network, supporting TCP applications over the Internet. In this paper, we present a new class of attacks, protocol-level attacks, against Tor. Different from existing attacks, these attacks can confirm anonymous communication relationships quickly and accurately by manipulating one single cell and pose a serious threat again...
