Network-on-Chips (NoCs) are important components for scalable many-core processors. Because the performance of parallel applications is usually sensitive to latency NoCs, reducing it a primary requirement. In this study, compression router that hides (de)compression-operation delay proposed. The (de)compresses contents incoming packet before switch arbitration completed, thus shortening length ...

This paper presents an asynchronous on-chip network router with Quality-of-Service (QoS) support. The router uses a virtual channel architecture with a priority-based scheduler to differentiate between multiple connections with various QoS requirements sharing the same physical channel. A gatelevel prototype of the router has been built and its functionality and performance is evaluated. The si...

Vol. 9 No. 3 1997 A DIGITAL router engineering team has refined and extended routing protocols to guarantee a five-second maximum loss-of-service time during a single failure in an Internet Protocol (IP) network. We use the term router cluster to describe our improved implementation. A router cluster is defined as a group of routers on the same local area network (LAN), providing mutual backup....

Click is a new software architecture for building flexible and configurable routers. A Click router is assembled from packet processing modules called elements. Individual elements implement simple router functions like packet classification, queueing, scheduling, and interfacing with network devices. Complete configurations are built by connecting elements into a graph; packets flow along the ...

In on-board mobile networks, users are connected to a local network that attaches to the Internet via a mobile router and a wireless link. The mobile router has a central role in servicing the mobile network, which makes the security of the mobile router crucial. The security of mobility management protocols used by mobile router, such as Mobile IPv6, have been studied thoroughly. However, the ...

Distributed Denial-of-Service (DDoS) attacks have become a major threat to the Internet. As a countermeasure against DDoS attacks, IP traceback schemes identify the network paths the attack traffic traverses. This paper presents a novel IP traceback scheme called Router Interface Marking (RIM). In RIM, a router probabilistically marks packets with a router interface’s identifier. After collecti...

Network-on-Chip (NoC) is most widely used as a communication framework to connect various Intellectual Properties (IPs) in an Integrated Circuit (IC). As technology scales down, buffers present NoC Router are more prone Multiple Cell Upsets (MCUs). To overcome this, Error Correction Code (ECC) introduced Router. Inclusion of ECC increases the number redundant bits stored buffer for error correc...

As chip complexity keeps increasing in system-on-chip (SoC), the on-chip interconnect has become a critical issue for large-scale chip design. It has been proposed that the packet-switched network exchanging messages between intellectual property (IP) cores is a viable solution for the SoC interconnect problem. The design of the router in such network-on-chip (NoC) architectures is the key to h...

This paper applies programming language techniques to a high-level system description, both to optimize the system and to prove useful properties about it. The system in question is Click, a modular software router framework [13]. Click routers are built from components called elements. Elements are written in C++, but the user creates a configuration using a simple, declarative data flow langu...
