  2. Outline • New Services • New Requirements • New Technology

  3. New Services • CDN: Content Distribution Network(e.g., AKAMAI) Distribute the Servers, Redirect Requests • DNS: (Name -> IP) randomized • Application: Web page -> Modified Links • Middleware: Redirection Servers (reached by anycast?)

  4. New Services (continued) • Storage (e.g., Brocade)

  5. New Services (continued) • ASP (e.g., CORIO)

  6. New Services (continued) • Distributed Services • Transport objects across network • Advertise services • Agents monitors ads and manage connections between servers and clients • Issues: • Scalability • Fault Tolerance • Load Balancing • Security

  7. New Requirements: • Hacker-Proof • Robust against DoS attacks • Robust against viruses, intrusions, physical attacks • Reliable: • 99.999% Availability • 50ms protection switching • Secure: • Confidentiality • Privacy • Authenticity • Non-Refutability

  8. New Technology: Network Processors • Motivation: • Header Processing more complex: IPv6, MPLS, VPN • Deep packet processing: Firewall, Intrusion Detection, NAT, Security • TCP termination within the network • Multiple Interfaces: POS, Fiber Channel, ATM, … • Complex Scheduling: QoS, CoS

  9. New Technology: Network Processors • Definition of NP: • Programmable packet processor that can implement networking functions • Desirable Features: • Full line rate: 2.5 – 10 – 40 Gbps • Classification • Traffic Management (Layer 3 + QoS) • Higher Layers (?): PPP termination, Load Balancing, …
