SDNbasedOpeneXchange Points

10#ONOSProject

Developedfunctionalities:SDX– L2

• Abstraction of virtual SDXs

• Implemented as a service that can be called by other subsystems within ONOS

• Monitoring and statistics (IPFIX export)

SDXL2app

Tunnelmodes

Based on MAC addresses, VLAN encapsulation, MPLS encapsulation (implemented in ONOS core)

CLI and GUI implementation

Dynamic peer administration

SDN-IP improvements

• Same-subnet BGP peers configuration

• Internal speaker can act as route server

• Direct communication between peers (via modified ProxyARP app)
