  1. CPSC 641: Performance Issues in High Speed Networks Carey Williamson Department of Computer Science University of Calgary

  2. Agenda ▪ Welcome! ▪ Course Overview ▪ Administrative Details ▪ Expectations ▪ Q&A ▪ Today’s Lecture Material: — Network Performance Issues — Networking Terminology Review — Examples: U of C Networking Research 2

  3. Overview ▪ CPSC 641 — Performance Issues in High Speed Networks ▪ Introductory-level graduate course on the basic methods and current topics in networking research ▪ Professor: — Carey Williamson — http://www.cpsc.ucalgary.ca/~carey ▪ Course Web site: — http://www.cpsc.ucalgary.ca/~carey/CPSC641 3

  4. Motivation “Opening a highway does not by itself drastically change the speed of the bicycles” - Ancient Proverb 4

  5. High Speed Networks: A Layered View Application Designers ▪ Web, Video, P2P, Email OS Architects ▪ Linux, Mac OS, Windows CPU, Memory,Disk ▪ PC, Intel, Grid, NAS Protocol Architects ▪ TCP, UDP, IP, IPv6 ▪ LAN Adapters, NICs LAN Interfaces ▪ GigE, ATM, WiFi, MPLS Media Access ▪ Fiber, SONET, LTE, OFDM Physical Devices 5

  6. Layering Considered Harmful? ▪ Faster media does not necessarily imply faster network applications ▪ New environments, platforms, applications ▪ Interdependence between layers ▪ Interactions between protocols ▪ Need to consider trends of all layers! 6

  7. CPSC 641: Course Overview ▪ Main focus: Internet technologies, protocols, and applications ▪ Secondary focus: Performance issues ▪ Textbook: None (notes+current literature) ▪ Goal: Understanding the current state of the art for high speed networking research and network performance issues 7

  8. Contact Information ▪ Professor: Carey Williamson ▪ Email: carey@cpsc.ucalgary.ca ▪ Office: ICT 736 ▪ Office hours: Mon 1:00pm-3:00pm ▪ Phone: (403) 220-6780 ▪ Web site: http://www.cpsc.ucalgary/~carey ▪ CPSC 641 Web site for info, slides, assignments: http://www.cpsc.ucalgary.ca/~carey/CPSC641 8
