VLPW: The Very Long Packet Window Architecture for High Throughput Network-On-Chip Router Designs. (August 2011) Haiyin Gu, B.En., Zhejiang University Co-Chairs of Advisory Committee, Dr. Paul Gratz Dr. Eun Jung Kim ChipMulti-processor (CMP) architectures have become mainstream for designing processors. With a large number of cores, Network-On-Chip (NOC) provides a scalable communication method...

A technology for multicasting packetized multimedia streams such as IPTV over the Internet backbone is proposed and explored through extensive simulations. An RSVP or DiffServ algorithm is used to reserve resources (i.e., bandwidth and buffer space) in each packet-switched IP router in an IP multicast tree. Each IP router uses an Input-Queued (IQ) switch architecture with unity speedup. A recen...

Increased bandwidth in the Internet puts great demands on network routers; for example, to route minimum sized Gigabit Ethernet packets, an IP router must process about packets per second per port. Using the “rule-of-thumb” that it takes roughly 1000 packets per second for every 106 bits per second of line rate, an OC-192 line requires routing lookups per second; well above current router capab...

The Bay Bridge is a high performance bridge/router capable of bridging and routing over 100,000 packets per second between two network ports. The first prototype provides a platform for the investigation of very high speed bridging and routing in hardware. High throughput is achieved by a specialised processor: The Protocol Converter, a programmable device for translating between network protoc...

The growing use of clusters in diverse applications, many of which have real-time constraints, requires quality-of-service (QoS) support from the underlying cluster interconnect. All prior studies on QoS-aware cluster routers/networks have used simulation for performance evaluation. In this paper, we present an analytical model for a wormhole-switched router with QoS provisioning. In particular...

One way to specialize a general purpose multi-core chip built using NoC principles is to provide a mechanism to configure an application specific deadlock free routing algorithm in the underlying communication network. A table in every router, implemented using a writable memory, can provide a possibility of specializing the routing algorithm according to the application requirements. In such a...

We have embedded an artificial atom, a superconducting transmon qubit, in an open transmission line and investigated the strong scattering of incident microwave photons (∼6  GHz). When an input coherent state, with an average photon number N≪1 is on resonance with the artificial atom, we observe extinction of up to 99.6% in the forward propagating field. We use two-tone spectroscopy to study sc...

In this paper, we address the problem of fair scheduling of packets in Internet routers with input-queued switches. The goal is to ensure that packets of different flows leave a router in proportion to their reservations under heavy traffic. First, we examine the problem when fair queuing is applied only at output link of a router, and verify that this approach is ineffective. Second, we propos...
