WiMaxWiMax BTS The BTS itself is a black box Slice isolation mechanism and control framework is outside of this box vBTS Substrate ASN Substrate Base Station (BTS) Un-modified WiMAX BTS (Black box) Data And Control Pipes
WiMax: ASN Packet Forwarding Removed all default IP routing, simplified ASN controller* Data path (CLICK) is purely based on MAC addresses Shaping mechanism (CLICK)for slice isolation vBTS Substrate ASN Substrate Base Station (BTS) * Work done at NEC
WiMax: vBTS Redirect all traffic from VLANs to individual slices Similar redirection from slices to outbound VLAN interfaces Grid services for creation, destruction, maintenance of slices, adding clients, slice allocation control … vBTS Substrate ASN Substrate Base Station (BTS) Virtual machine instances Dynamically created VLANs
WiMax Aggregate Managers Two AMs: WimaxRF and WimaxVM WIMaxRF: Used for BS management WiMaxVM: Used for vBS management • Initialize the grid service: • wget http://wm-asngw-02:5012/wimaxvm/initvms • Start/Stop VM instance • wget http://wm-asngw-02:5022/wimaxvm/start?vmname = vm1 • wget http://wm-asngw-02:5022/wimaxvm/stop?vmname = vm1 • Configure VLANs on VM substrate • Registers a client with the slice • wget http://wm-asngw-02:5012/wimaxvm/addclient?vmname = vm1\& clientmac = 84:22:10.14.2b.9a
Milestone & QSR Status (contd.) INSERT PROJECT REVIEW DATE
Accomplishments 1: Advancing GENI Spiral 2 Goals • Major Accomplishments: • GENI wide-are wireless support with basic capabilities demonstrated at GEC7 and GEC8 • Successful deployment at 3 sites (Rutgers, Poly and BBN) INSERT PROJECT REVIEW DATE
Issues • Support for other datapath implementations (openflow?) • Coexistence with other 4G providers (Sprint) • Switch back to single server implementation INSERT PROJECT REVIEW DATE
Plans • What are you plans for the remainder of Spiral 2? • GEC9 Demo • Finishing installation and integration of all 7 sites • OMF5.3 transition • What are your thoughts regarding potential Spiral 3 work? • Multi-sector/Multi-site support • Client virtualization support • Integration with other frameworks INSERT PROJECT REVIEW DATE
