  1. Reduce, Reuse, RecycleImproving Reliability by Simplifying Infrastructure Vivek Pai Princeton University

  2. Anti-DDoS box DNS server Firewall IM Server Intrusion detector LDAP server Load balancer Mail server P2P cache Proxy server Router Spam blocker Traffic shaper Virus scanner WAN optimizer Web server ISP/Enterprise Infrastructure, Sorted Alphabetically

  3. Should You Feel Safe? • Many boxes are appliances • With their custom Oses • With their “sufficient” hardware • And their own little quirks • Examples • DoS the university packet shaper • DDoSing the department firewall

  4. Proposal: Bumps In the Wire • Reduce • Build sharable OS/appliance infrastructure • Multiple services per box • Reuse • DoS – Firewall, Web, DNS, Mail • Cache – WAN, Web, P2P • Scan – Web, Mail, IM • Recycle • Underutilized CPU, memory

  5. Hardware Directions Multiple cores/chip + Hardware VM support = Multiple domains per box, With fine-grained resource control

  6. Research Areas • Protection • VM, OS, Process, Language • Allocation • Design • OS, substrate, service, hardware • Composition, decomposition • Multi-box coordination

  7. Feasibility • Technical • We’re doing it for TCP request/reply • New protections for Apache, Flash, etc • Administrative • What about ICAP, OPES? • Commercial • Focus on service, not hardware
