  2. Outline • Introduction to NetServ • Hands-on tutorial • NetServ under the hood • Wrap-up

  3. WhatisNetServ? • In-network service container • Java-programmable, signal-driven router • Active networking 2.0

  4. NetServ and GENI • NetServ was a GENI Alpha project • Demonstrated at GEC9 plenary session • NetServ as GENI-Lite • Deploy Java modules instead of VMs • What is it good for? • Rapiddevelopment and prototyping on GENI • Sharing GENI resources – ex. classrooms

  5. NetServNode Architecture Server modules Client- Server data packets NSLP daemon OSGi control sockets OSGi Service Container NetServ Controller UNIX socket Packet processing modules NetServ Control Protocol (TCP) Transport layer GIST daemon OSGi OSGi Service Container Service Container iptables command Raw socket Forwarded data packets NFQUEUE #1 NFQUEUE #2 Netfilter Signaling packets Linux kernel

  10. NSIS-based on-pathsignaling NetServrepository Signaling message is sent towards the destination rather than to a specific router N1 N2 N3

  11. Future Work • OpenFlow integration • NetServ node as a side-car • NetServ on commercial router • JUNOS SDK • Internet multicast using NetServ • Hybrid of ALM and IP multicast • Authentication and authorization using RPKI

  12. Wrap-up • Please complete a (very) short survey • Link at the end of the step-by-stepinstruction • NetServ homepage • http://www.cs.columbia.edu/irt/project/netserv/ • Subscribe to netserv-users mailing list • Wewould appreciateyour feedback!
