4 Workshop Purpose Purpose of the kits program» strengthen research community through better tools» open, extensible high performance networking research platform» enable more effective sharing of efforts -- new network capabilities, end-to-end protocols, OS support, middleware, applications Share Ideas» how to use kits most effectively in systems research» what the important research directions are» how to make the kits better Develop Collaborations» better tools for using kits» middleware for controlling network of kits» research projects Please get involved and get others involved» tell us how we can help you» tell us how you can help us and how you can help others Jonathan Turner 11/8/99 4

5 Partial List of Kits Applications High performance routing -- SUNY-Stony Brook, WashU Distributed interactive simulation -- U. of Central Florida Distributed medical imaging -- U. of Iowa Active networking -- Georgia Tech, Kentucky, Mississippi State, WashingtonU Traffic management and QoS -- U. of Texas, U. of South Florida, Naval Postgraduate School Parallel computing -- Brown, Yale, Rice, New Mexico State, U. of Tennessee, U. of Stuttgart Network signaling -- Columbia, WashingtonU Network management -- U. of Iowa, WashU Wireless networking -- Southern Methodist University, Technical University of Berlin Jonathan Turner 11/8/99 5

6 Kits Status Switches completed and shipped last fall groups Shipments completed to almost all kits users» still no license agreement with Tennessee & Kansas Several kits remain unallocated APIC NICs finally completed - will start shipping soon Several bugs in APIC -- none fatal» interrupt register problem during boot process» incorrect receive-side byte-swapping logic for Intel PCs general solution requires software byte-swapping on receive for APIC-to-APIC transfers can avoid software byte swapping» APIC hangs on certain receive buffer configurations workaround is to avoid problem configurations Jonathan Turner 11/8/99 6

7 Smart Port Card (SPC) Line Card R OE X Pentium 166 MHz cache SPC PCI Bridge APIC 32+ MB System FPGA IPP OPP SPC fits between switch IPP/OPP and line card (can use with any line card). Can stack multiple SPCs for higher performance. Includes APIC, Pentium, PCI bridge, memory & System FPGA. Using development board have tested all components, loaded and run NetBSD kernel. SPC board design now complete and in fabrication. Planning to use in active networking project & make available through STS (possibly by early fall). Jonathan Turner 11/8/99 7

8 Port Processor Extender (PPX) Line Card R OE X PP Extender Memory FPGA FPGA Memory Pentium 166 MHz cache SPC PCI Bridge APIC 32+ MB System FPGA IPP OPP PP Extender can be combined with SPC or used independently. On-board FPGAs can be programmed for various functions.» IP address lookup and packet classification» per VC/flow queueing -- input or output side» ATM UPC/traffic shaping or DiffServ marking» hardware plug-ins for active processing John Lockwood (now of WashU) has NSF grant to distribute cards like this to kit program participants.

9 WUGS-160 ITI ITI ITI IPP IPP IPP OPP OPP OPP OTI OTI OTI I/O Module MX MX MX ITI IPP OPP OTI MX Three stage network with 160 Gb/s of I/O bandwidth. 8 I/O modules include IPPs, OPPs, line cards, first and third stage s. Four network cards carry center stage s. Passive backplane interconnects line modules and network cards Line cards on I/O modules contain transmission interfaces» quad OC-12 card, dual G-link, OC-48 interfaces Will correct speed limits in current chips and provide new features. Potential for remote use by kit participants and/or upgrading of kits. Jonathan Turner 11/8/99 9

10 Reserving Bandwidth Across Datagram Nets Site-to-Site Signalling ATM Net Std. IP Net Ext. IP Net Resource Mgr. APIC ATM Net Std. IP Net Ext. IP Net Std. IP Net ATM Net Std. IP Net Ext. IP Net Resource Managers control bandwidth at WAN access bottleneck.» local signaling using native protocols plus site-to-site signaling» per flow transmission scheduling and TOS marking» destination-end jitter reduction Enable connection-oriented applications over vbns and commodity internet.

11 Towards Multiservice Networks Signalling & Control NSP NSP NSP SC SC SC NOC SC Hosts may send IP packets or request services from Network Service Processors (NSP) - e.g. ATM VCs, RSVP, other. NSPs request services from particular routing switches, through the switches Switch Controllers (SC) - GSMP or similar interface. NOCs enable human managers to monitor systems and deal with exceptional conditions. Jonathan Turner 11/8/99 11

12 Multiservice Routing Switch Switch Controller (SC) manages system.» insulates network services layer from hardware-specific details» implements switch services protocol (e.g. GSMP) & switch mgmt. protocol (e.g. SNMP)» interacts with PCs using internal switch control protocol based on CORBA» implements link management protocols Port Processors (PP & PPX) provide per port forwarding functions in hardware. Smart Port Card (SPC)» per port control functions, including configuration of port hardware» forwarding and queueing for IP in some configurations» programmable network services» contain embedded processor and memory Switch Services Protocol Internal Switch Control Protocol Jonathan Turner 11/8/99 12 SC Scalable Switch Core PP PP PP PP PP PP PP SPC SPC SPC SPC SPC SPC SPC PPX PPX PPX PPX PPX PPX PPX LC LC LC LC LC LC LC Switch Mgmt. Protocol Line Cards (LC) implement physical interface to link.» ATM, IP-over-ATM, IP-over-SONET, IP-over-Ethernet» OC-3, 12, 48, G-link, Gigabit Ethernet

13 Research Directions Applications for connection-oriented networks (ATM & IP)» multiparty voice & multimedia conferencing» high quality real-time video distribution and video-on-demand» connection-oriented web browsing - explicit rate f.c., cache connections» web indexing to support search engines Next generation internet routers» fast address lookup and packet classification» per flow queueing and packet scheduling for QoS» signaling for bandwidth reservation and multicast» QoS routing, network-supported flow control Adding computational capabilities to switches & routers.» will soon be feasible to execute several hundred instructions for every word received on a 2.4 Gb/s network link» multimedia applications - audio processing, video transcoding» encryption and security enhancements» computational proxy for wireless devices Jonathan Turner 11/8/99 13
