ActuatorPolicy-based Routing Layer

• Assign ID to incoming packets (hash table
  lookup)
• Route based on IDs, not locations (i.e., not IP
  addr)
• Sets up logical paths without changing network
  topology
• Set of common middle boxes get single ID

Load- Balancer (IDLB)
Intrusion- Detection (IDID)
Service (IDS)
Firewall (IDF)

• So simple can be done in FPGA?
• More general
• than MPLS

Identity-based Routing Layer
