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?)

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
new requirements
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
new technology network processors
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
new technology network processors9
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, …
