• SDNBoD createsL2serviceswithQoS

• ItrunsasONOSapplication

• Providesmulti-domain BoD services involvingheterogeneous transport

technologies

• ThroughNSI-CS protocol,itinteractswiththelegacyGÉANTBoD service

(AutoBAHN)

• EnforcesQoS constraints suchasratelimiting

• EnhancescurrentBoD serviceswithfailurerecoverymechanismsand

automatednetworktopology discovery

• GÉANTSDXisahybridenvironmentthatprovidesbothL3andL2connectivityservices:

• SDXL3 ONOSapp:providesIPtransitserviceviaBGPtocustomers(IXP)

• SDXL2 ONOSapp:createsL2tunnelsbetweenMAC/VLANendpoints,taggedwithVLAN/MPLS

SoftwareDefined InternetExchangePoint

Networks·Services·Peoplewww.geant.org 9

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

Networks·Services·Peoplewww.geant.org

Developedfunctionalities:SDX– L3

Dynamic peer administration

SDN-IPimprovements

• Same-subnet BGP peers configuration

• Internal speaker can act as route server

• Direct communication between peers (via modified ProxyARPapp)

Extended app(SDXL3)
