Regards, Utham An Optical Booster for Internet Routers Although optical technologies have been effectively employed to increase the capacity of communication links, it has proven difficult to apply these technologies towards increasing the capacity of Internet routers, which implement the central forwarding and routing functions of the Internet. Motivated by the need for future routers that will forward packets among several high-speed links, this work considers the design of an Internet router that can forward packets from a terabit-per-second link without internal congestion or packet loss. The router consists of an optical booster integrated with a conventional (mostly electronic) Internet router. The optical booster processes Internet Protocol packets analogously to the hosting router, but it can avoid the time-consuming lookup function and keep packets in an entirely optical format. An optically boosted router is an inexpensive, straightforward upgrade that can be deployed readily in a backbone IP network, and provides optical processing throughput even when not deployed ubiquitously. This talk discusses the design of the optical booster and results obtained from simulations of the optical booster with both synthetic and real network traffic From optical-networks@mailman.isi.edu Thu Nov 8 01:41:33 2001 From: optical-networks@mailman.isi.edu (Michelle C.

Our group is looking forward to seeing your talk. It looks like everyone from OC Lab will be able to attend the talk from 12 to 1 (16 students plus Dr. Willner) so it will be a full room! What equipment will you need for your presentation (overhead projector or LCD projector)? See you tomorrow in EEB 108!

LCD I suspect... Utham - please mail me your slides so I can have them on my machine as backup.

References: <3BC21A18.3C24A0BA@tsotech.com> <3BC21AA2.70307@isi.edu> <3BC22986.E631E7D8@tsotech.com> <3BC244AB.6070303@isi.edu> Message-ID: <3C056089.1030703@isi.edu> Hi, all, This is a bit out of scope for optical nets, but for those of you who are curious about some of the other work we do at ISI, there is a talk this Friday that may be of interest. The talk is in the Math Dept, 4:00 p.m. in DRB 337 this Friday. ----------------------- An Architecture for Virtual Internets Virtual networks (VNs) provide an abstraction for network infrastructure to simplify distributed (peer) applications, extend private infrastructure over public networks, and support the development and incremental deployment of new protocols (M-Bone, 6-Bone, A-Bone). VNs typically require custom protocols with operating system support, e.g., GRE, PPTP, or L2TP, or application support (peer nets, A-Bone). A Virtual Internet (VI) can be created from a combination of virtual interfaces and IP encapsulation, together with the judicious configuration of internal routes, and support existing applications without new protocols or operating system support. This VI architecture augments the Internet with host and router multihoming, and supports customized topologies and multi-level virtualization (layering). The VI uses two layers of IP encapsulation to support dynamic routing together with IPsec, and to allow smaller base networks to emulate larger virtual ones via revisting components. A VI can thus create a 100-node ring by visiting each of 5 routers 20 times. The architecture has been implemented as a system for dynamic overlay deployment and management called the 'X-Bone,' intended for rapid configuration of experiment testbeds and demonstration systems. Because it also supports layered (recursive) overlays, this VN architecture is currently being developed to deploy parallel overlays for fault tolerance, in a system called the 'DynaBone.'

He has been at ISI since 1992, when he received his Ph.D. from the University of Pennsylvania, and has previously held positions at GTE Laboratories, Bell Communications Research, and NASA Goddard Space Flight Center. His research interests include virtual networks, high-speed protocols, empirical protocol performance analysis, Internet architecture, and protocols for latency reduction. Joe is currently directing a DARPA-funded project on fault tolerant networks (DynaBone), and also works on projects on optical Internets (POW), geographic routing (GeoNet), and Smart Space devices for user presence. He has led prior projects on gigabit LANs (Atomic-2), NIC design (PC-Atomic), multicast web caching (LSAM), and the automated deployment and management of virtual networks (X-Bone). At USC he designed and runs an summer internship program (SGREP), taught the Advanced Operating Systems and Advanced Systems Lab classes, and advises a number of Ph.D. students. Joe is a member of Sigma Xi, IEEE, and ACM, co-Chairs the IEEE ITC (Internet) committee, and is active in the IETF. He also serves on the editorial boards of IEEE Network and Elsevier's Computer Networks, and is a member of several program committees, including IEEE Infocom and IFIP's Protocols for High-Speed Networks.
