  2. Abstract • This document proposes extensions to PMIP6 that • Allows flow identification and binding during the flow mobility • Enable PMIP tunnels set up based on the service flow granularity between a pair of LMA/MAG • Therefore, multiple service flows of the MN can be separately controlled, e.g. Qos, charging, traffic control.

  3. Problem Status • What’s the requirement? • For different services, we want to have different charging rate, service quality, and latency. • E.g. User can bear some latency of the streaming TV, but require a high quality of voice service. • What’s the status? • Currently, there is single PMIP tunnel between a pair of LMA/MAG • It’s no difference in the tunnel for multiple services • Service-differ control can not be achieved based on the tunnel

  4. Protocol Operation • When a new service flow of the mobile node is started, it will trigger the service flow proxy binding update • MAG sends the PBU message to LMA including the service flow identifier option and the assigned downlink GRE Key for this SF. • LMA will generate the uplink GRE key and return a PBA message. • The new bi-directional tunnel for this specific service is set up

  5. Message Formats • Service Flow Identifier option • included in the PBU/PBA • Service Flow Identifier • A 16-bit unsigned integer, including the unique identifier within the LMA for the service flow of the mobile node. • However, its length can also be implementation dependent. • Service Flow Description option • The detailed binary encoding of the service flow description field could follow the defined binary traffic selector in draft- ietf-mext-binary-ts • Or the new traffic selector can be defined

  6. Scenario • SFID is used to identify the service flow • SFID can enable the flow binding • Refer to a SFID, there is a unique PMIP tunnle • SFID is unique in one LMA
