An optoelectronic router with a shuffle exchange network is presented and enhanced by adding micro-optical-electrical mechanical systems (MOEMS) in the network to add the ability to reconfigure the shuffle network. The MOEMS described here are fully connected any-to-any crossbar switches. The added reconfigurability gives the opportunity to adapt for different common application characteristics...

In this paper we describe some recent developments in how optics can be used inside Internet routers to scale capacity and reduce power. At Stanford University we are currently designing a 100Tb/s Internet router with an optical switch fabric that guarantees 100% throughput for all traffic.

Tratflc Matrlx AbstractA detailed analytical traffic model for alloptical wavelength division multiplexing (WDM) photonic packet switched networks is presented and the requirements for buffer size, and link dimensions are analyzed. This paper shows that due to the topology, packets may generate traffic bottlenecks produced by a tendency of the routing scheme to send packets with different desti...

Security First Network Bank (SFNB) (http://www.sfnb.com) went on-line in October 1995 as the world’s first on-line bank. The paper discusses how the security architecture was designed and implemented using the most currently available security technologies. The encryption technologies used to transport information across the Internet are widely known. Less widely known is how to protect the sys...

In this work, we implemented the Click IP Router Kernel in C language provided by Scott Webber et al. for two VLIW processors designed for DSP purpose, namely the Philips Trimedia TM1300 processor and Texas Instrument TMS320C6701 processor. The performance of these processors are compared with those of three other processors, ARM SA-110, HPL-PD EPIC, and Intel IXP1200 [1]. Ways of further perfo...

In this paper, we propose a distributed contention resolution scheme to reduce blocking probability in optical burst-switching networks. The scheme takes priority, propagation delay from the ingress router, and the burst-size into account to resolve contention, and guarantees that at least one of the bursts succeeds when contention occurs. We use a control packet to delay transmission of the co...

Abstract — Input queueing is becoming increasingly important for high-bandwidth switches and routers. In previous work, we proved that it is possible to achieve 100% throughput for input-queued switches using a cell-by-cell scheduling algorithm called LQF. However, LQF is too complex to implement in hardware. In this paper we introduce a new algorithm called Longest Port First (LPF), which is d...

The an efficient packet marking technique called swapnil’s packet marking and tracebacking (SPMT) technique that requires the amount of packets equal to the hop distance between the attack initiator and the server (destination) [1], which is less than 31 hops [3] [4], and can undergo certain kind of attacks like constant ID field value, and absence of router in the network chosen for marking. I...

While it is widely known that port scanning is widespread, neither the scanning landscape nor the defensive reactions of network operators have been measured at Internet scale. In this work, we analyze data from a large network telescope to study scanning activity from the past year, uncovering large horizontal scan operations and identifying broad patterns in scanning behavior. We present an a...
