1. Lucy Yong (lucyyong@huawei.com) Young Lee (ylee@huawei.com) 67 th IETF San Diego November 2006 GMPLS Extension for Reservation and Time based Bandwidth Service

2. 67th IETF San Deigo Nov. 20062 Draft Objectives Increase GMPLS value for automatic bandwidth service Enable control plane to support time based bandwidth service

3. 67th IETF San Deigo Nov. 20063 GMPLS Instant BoD Service Model Customer service request comes at service connection time and network set up connection instantly However, this service model is rarely deployed in carrier network today because –Optical transport services are relatively static and may be planed ahead of service time –Hard to predict user demand and guarantee the service when it needs –Challenge for control plane security when UNI is used –Infrastructure complexity under multiple administration domains –May take time to run path clean in data plane after bandwidth is allocated –Present a big challenge for service operation and back office integration

4. 67th IETF San Deigo Nov. 20064 How to raise GMPLS value for service? Today, carrier use control plane to set up soft permanent connection (SPC) to achieve provisioning acceleration However, although GMPLS is used within network, the procedure from customer request to bandwidth establishment takes tedious processes Could GMPLS be used to further improve the process for bandwidth services? Could GMPLS be used to enable service intelligence?

5. 67th IETF San Deigo Nov. 20065 Transport Bandwidth Service Example Customer Order Pre- Provisioned Pre- Provisioned Management Plane Control Plane Data Plane Customer order is ahead of service time, access point is nailed up ahead Soft Permanent Connection is set up when service time arrives Customer may want to change the connection during the service time without restart a new order. For example, path modification or bandwidth modification These could be done by reservation based and time based bandwidth service SPC provisioning Network customer

6. 67th IETF San Deigo Nov. 20066 Reservation Based Bandwidth Service Definition: bandwidth service can be booked prior to the service time, when the service time arrives, the connectivity will be available to the user Reservation based service decouples service request and service usage. It has some advantages –Service can be better guaranteed at usage time –Give provider a chance to prepare network resource –Fit for most of large and long term bandwidth demand –Allow provider to verify data plane path ahead –Align with today’s private line service model –Enable time based bandwidth services –Enable other advanced bandwidth services such as L1&2VPN and Bandwidth trading Carrier can implement reservation based service in different ways. It does not have to allocate network bandwidth at booking time

7. 67th IETF San Deigo Nov. 20067 Time Based Bandwidth Service Definition: Connection can be described as a function of time such as time of day or day of week. In other words, connection can vary in a time pattern Connection service pattern could be converted as time based policy profile Time based policy profile is sent to connection origination node, when the event time comes, control plane will take the action such as path setup, teardown, or modification As a result, connection is managed as a function of time. For example, connection is up between A to B for certain period and up between A to C for another period

8. 67th IETF San Deigo Nov. 20068 Time Based Connection Example Rule TypeTime DurationAction TOD Time of Day 8AM-5PMMaintain Connection OtherTerminate Connection DOW Day of Week M-FMaintain 600 Mbps Sa-SuMaintain 200 Mbps Combined rule could be implemented

9. 67th IETF San Deigo Nov. 20069 Requirements For reservation based service –Allow customer to view all its access points to the network –Allow customer to specify connection service ahead of service time among its access points –Validate a service request via OSS –Store service requests –Initiate bandwidth request when service time arrives –Allow customer to specify time based services –Allow customer to change or conceal the service ahead of service time For time bases service –Allow connection changing as customer specified time –Change connection paths, bandwidth or other –Record service report for customer

10. 67th IETF San Deigo Nov. 200610 Bandwidth Resource Reservation Reservation based services allow provider to plan network resource based on the booking –A bandwidth pool could be engineered ahead based on the booking, no need to allocate bandwidth at booking time. However –An individual bandwidth could be allocated ahead if requested under certain condition such as time and price In case, an overbook happens, carrier will give a “rain check” to the customer whose service get bumped

11. 67th IETF San Deigo Nov. 200611 Could this be done in management plane? Yes, today this is done by management plane with tedious processes However, one of control plane objectives is to simplify existing OSS and improve service automation This could be also a part of control plane function or integrated function between control plane and management plane The objective here is how to leverage GMPLS value for service automation and advanced services enabling such as L1VPN

12. 67th IETF San Deigo Nov. 200612 Next Steps Is this something interested to CCAMP WG? If yes, accept the draft as WG draft and work on the solution in architecture and protocol The draft contains more information draft-yong-ccamp-ason-gmpls-autobw-service-00.txt
