  1. Mobile Agents in Click Tushar Mohan

  2. Click Elements • Graphs made of simple elements • Separate flows have separate ports • Common case fast • Reduce function calls • Ports of elements - PUSH, PULL, AGNOSTIC

  3. Advertisements and Registration M F H

  5. Home/Foreign Agent Element ToDevice eth1 To Classifier 1 1 FromDevice eth1 2 IP 0 0 Strip Agent LookUpIPRoute FromDevice eth0 ARPResponder Classifier

  6. Home Agent Configuration • Input 0 : • Normal IP + IP for forwarding + UDP registration requests • Input 1 : • Agent Interface Ethernet packets for which we Proxy/Gratuitous ARP • Possible de-registration request • Output 0 : • Normal IP + Encapsulated IP • Output 1 : • Unprocessed Ethernet packets from Agent Interface • Output 2 : • Proxy/Gratuitous ARPs

  7. Foreign Agent Configuration • Input 0 : • Normal IP + Encapsulated IPIP + UDP registration replies • Input 1 : • Registration requests Eth/IP/UDP + Passing ethernet packets • Output 0 : • Normal IP + Relayed registration requests • Output 1 : • Unprocessed Ethernet packets from Agent Interface • Output 2 : • De-capsulated packets + Relayed replies

  11. What Remains ? • Not fully compliant (RFC2002) • ARPs, validation, authentication • multiple simultaneous binding • Speed-up (hash classes) • Hardware testing • Documentation • Integration with the MIT toolkit

  12. Objectives • Add to the Click tool-kit • Practically implement a protocol • Enjoy the project
