Each of you will work with HALF of the above First you will do some simple exercises
Ping Traffic Monitoring
Then you will try to join your Network with a Peer This Demo will show how your final result FPIFght look

Demonstration Configuration Two Slices
» Each Slice implements a separate Overlay IPv4 network Slices joined by a negotiated Interface
» Each Slice defines a Fastpath Interface on an interconnecting link Demonstration and Hands-on exercises focus on traffic from Src to Dst.
» Not to do full general routing. Configuration script will:
» Reserve resources» Create an endpoint for monitoring daemon» Create a Fast Path» Create necessary Fastpath Interfaces» Bind 1 queue to each Fastpath Interface
• More is possible but we’ll keep it simple for today» Add Filters for desired routing
PlanetLab hosts will be used for Traffic Sources and Destinations Traffic Generator we built for our IPv4 Overlay Router will be used to
generate traffic Real time monitoring will be used to visualize what happens

Overlay Packet Format Overlay Packets arrive at a Fastpath Interface encapsulated in a UDP
Tunnel It is the identification of the Fastpath Interface by IP Addr and UDP Port#
that designates a packet to be delivered to a specific Fastpath The UDP payload contains the Overlay packet The IPv4 Destination Address in the Overlay packet header is what we
will have our Filters match on. Addresses below are for a pkt leaving srcN destined for dstN+1
