- 2. Concept for “Utility” Bandwidth • Low latency, high bandwidth services (>1Gb/s) are emerging requirements for business, medical, education, government and industry • New applications development and business models could be stimulated by affordable and easily accessible high bandwidth in both local and wide area networks • High bandwidth connections are typically full period today but full period 7x24 bandwidth is not always needed. • Technologies are now available that suggest plausible new business model options to offer time slots for high bandwidth services – Dynamic provisioning of lambda and sub-lambda time slots – Periodically scheduled (N time slots per day, per week) or ad hoc
- 3. Application Profile A – Lightweight users, browsing, mailing, home use B – Current business applications, multicast, streaming, VPNs, mostly LAN C – Emerging business, government, industry & scientific applications, data grids, virtual-presence Network Profile A – Internet routing, one to many B – VPN services on/and full Internet routing, several to several C – Very fat pipes (both full and non-full period services), limited multiple Virtual Organizations, few to few User/Bandwidth Profile BW requirements sr esu f o # A ADSL C A B ADSL GE
- 4. Dynamic Wave Provisioning Service Business Model Examples • Business Continuity/Disaster Recovery – Remote file storage/back-up – Recovery after equipment or path failure – Alternate site operations due to natural or man-made disaster • Storage and data on demand – Rapid expansion of network attached storage capacity – Archival storage and retrievals – Logistical networking – pre-fetch and cache • Financial community and transaction GRIDs – Distributed computational and storage resources – Shared use of very high bandwidth network resources – Utility computing for pay-as-you-go business models
- 5. 100s of transactions per second Core network is a shared resource • SLAs for graduated performance • Fixed time slots − Lambdas & sub-lambdas • Dynamically allocated 100s of transactions per second 100s of transactions per second Remote storage / processing location Remote storage / processing location Remote storage / processing location Dynamically provisioned carrier or large enterprise network – switched lambdas and sub-lambdas
- 6. Transaction GRID Demonstration • Real-time transactions processed and buffered at collection sites for Businesses “BB” & “SRU” • Periodic transfer to remote site for batch processing using fixed timeslot dynamic lambda provisioning • High bandwidth/low holding time connection provides periodically scheduled shared use path between collection and remote sites.

- 12. DWDM-RAM Architecture ODIN – Optical Domain Intelligent Network • Software suite that controls the OMNInet through lower-level API calls • Designed for high-performance, long-term flow with flexible and fine grained control • Stateless server, which includes an API to provide path provisioning and monitoring to the higher layers Applications Data Transfer Scheduling Network Resource Scheduling Communication Protocols ODIN OMNInet Application Collective Resource Connectivity Fabric
- 13. DWDM-RAM Architecture Communication Protocols • Standard off-the-shelf communication protocol suites • Provide communication between application clients and DWDM-RAM services and between DWDM-RAM components • Communication consists of mainly SOAP messages in HTTP envelopes transported over TCP/IP connections Applications Data Transfer Scheduling Network Resource Scheduling Communication Protocols ODIN OMNInet Application Collective Resource Connectivity Fabric
- 14. DWDM-RAM Architecture Network Resource Scheduling • Essentially a resource management service • Maintains schedules and provisions resources in accordance with the schedule • Provides an OGSI compliant interface to request the optical network resources Applications Data Transfer Scheduling Network Resource Scheduling Communication Protocols ODIN OMNInet Application Collective Resource Connectivity Fabric
- 15. DWDM-RAM Architecture Data Transfer Scheduling • Direct extension of NRS service, provides an OGSI interface • Shares same backend scheduling engine & resides on same host • Provides a high-level functionality • Allow applications to schedule data transfers without the need to directly reserve lightpaths • The service also perform the actual data transfer once the network is allocated Applications Data Transfer Scheduling Network Resource Scheduling Communication Protocols ODIN OMNInet Application Collective Resource Connectivity Fabric

- 18. DWDM-RAM Modes • Applications may request a data transfer • Applications may request a set of resources through a resource allocator, which will handle the network reservation Applications Resource Allocator Network Resource Scheduling Applications Data Transfer Scheduling Network Resource Scheduling
- 19. The Network Service • NRS is the key for providing network as a resource – It is a service with an application-level interface – Used for requesting, releasing, and managing the underlying network resources – Understands the topology of the network – Maintains schedules and provisions resources in accordance with the schedule – Keeps one scheduling map for each lambda in each segment
- 20. The Network Service Scheduling maps: Each with a vector of time intervals for keeping the reservations. Scheduling maps for each segment
- 21. The Network Service • NRS – Provides an OGSI-based interface to network resources – Request parameters • Network addresses of the hosts to be connected • Window of time for the allocation • Duration of the allocation • Minimum and maximum acceptable bandwidth (future) – Provides the network resource • On demand • By advance reservation – Network is requested within a window • Constrained • Under-constrained
- 22. The Network Service • On Demand – Constrained window: right now! – Under-constrained window: ASAP! • Advance Reservation – Constrained window • Tight window, fits the transference time closely – Under-constrained window • Large window, fits the transference time loosely • Allows flexibility in the scheduling
- 23. The Network Service Under-constrained window • Request for 1/2 hour between 4:00 W and 5:30 on Segment D granted to User W at 4:00 • New request from User X for same segment for 1 hour between 3:30 and 5:00 • Reschedule user W to 4:30; user X to 3:30. Both requests are satisfied. Route allocated for a time slot; new request comes in; 1st route can be rescheduled for a later slot within window to accommodate new request 3:30 4:00 4:30 5:00 5:30 X 3:30 4:00 4:30 5:00 5:30 W X 3:30 4:00 4:30 5:00 5:30
