8  Identities and commonly used valuesp. 22

8.1  Generalp. 22

The common identities for SEAL refer to TS 23.434. The following clauses list the additional identities and commonly used values for SEALDD.

8.2  SEALDD server IDp. 22

The SEALDD server ID uniquely identifies the SEAL data delivery server.

8.3  SEALDD client IDp. 23

The SEALDD client ID is a globally unique value that identifies the SEAL data delivery client.

8.4  SEALDD-UU flow IDp. 23

The SEALDD-UU flow ID is used by the SEALDD client and SEALDD server to identify different VAL application traffic, which has the same attributes, e.g. the same 5-tuple, media type, QoS requirements. The SEALDD-UU flow ID should be uniquely identified with the SEALDD-UU connection.

9  Procedures and information flowsp. 23

9.1  Generalp. 23

The VAL application data/content can be stored in the VAL server, or the SEALDD server, or other cloud platform. For the downlink traffic transmission, the SEALDD server can retrieve the data/content of VAL application, by using one of the following modes:
  • Downlink pull mode: the SEALDD server can pull the data/content of VAL application from the address provided by the VAL server (i.e. pull from the data/content address in VAL server over SEALDD-S interface, or in other cloud platform).
  • Downlink push mode: the VAL server can push the data/content of VAL application to the SEALDD server over SEALDD-S interface.
For the uplink traffic transmission, the SEALDD server can sends the data/content of VAL application to the address provided by the VAL server, by using one of the following modes:
  • Uplink pull mode: the VAL server can pull the data/content of VAL application from the SEALDD server over SEALDD-S interface.
  • Uplink push mode: the SEALDD server can push the data/content of VAL application to the address provided by the VAL server (i.e. push to the data/content address in VAL server over SEALDD-S interface, or in other cloud platform).
