What is an IXP ?
An Internet Exchange Point (IXP) is a network facility that enables theinterconnection and exchange of Internet tra�c between more than twoindependent Autonomous Systems.
Direct benefit :
Lower Latency
Reduce transit cost
Increase security

IXP switching fabric are shared Layer 2 broadcast domain
Broadcast tra�c can weaken router CPU or even neutralize the entire IXP
Loop Free solutions are not perfect

Operator-oriented OpenFlow IXP fabric
Operator-oriented OpenFlow IXP fabric No more Broadcast and perfect edge filtering
Pseudo Wire
Can run even if the control plane is down
Works even without OpenFlow switch in the core
Fined-grained monitoring with OpenFlow
Link redundancy with Group Fast Failover
Scalable for more PoPs and IXPs Members
Open to future applications Oriented IXP Customer

Issues reported IPv6 ICMPv6 Neighbor Discovery
Matching ICMPv6_ND_TPA not supported by BCM ASICs in combination with ARP_TPA matching
Solutions have been found
OpenFlow ASICs need to be improved
