5. Bluetooth SDP features 4 An SDP block generates and receives Bluetooth SDP commands and responses from the lower layers of the Bluetooth stack 4 SDP involves communication between an SDP server located on RemDev and and SDP client located on LocDev 4 The server maintains a list of service records that describe the characteristics of services associated with the server

6. Bluetooth SDP feature(cont.) 4 SDP uses a request/response model where each transaction consists of one request protocol data unit(PDU) and one response PDU. 4 ServiceSearch Transaction 4 ServiceAttribute Transaction 4 ServiceSearchAttribute Transaction 4 Browsing for Services(use BrowseGroupList attribute)

7. Bluetooth Profile Stack 4 Service discovery user application(SrvDscApp) in a local device(LocDev) to sedn service inquiries and receive service inquire responses fromother remote devices(RemDev) 4 SDP uses the connection-oriented(CO) transport service in L2CAP, which in turn uses the baseband asynchronous connectionless(ACL) links to carry ultimately the SDP PDUs over the air

11. Salutation features 4 Salutation Manager(SLM) functions as a service broker for applications, services and devices called a Networked Entitiy. 4 Service: register its capability with a Salutation Manager 4 Client: discovers Services and requests to use them through a Salutation Manager

12. Salutation features (cont.) 4 SLM-API: Salutation Manager Application Program Interface 4 Salutation Manger Protocol 4 TM: Transport Manager 4 A Salutation Manager binds to a specific transport through a TM unique to that transport class

13. Service Broker Task 4 Salutation Manger provides four basic tasks to perform as service broker 4 Service Registry 4 Service Discovery 4 Service Availability 4 Service Session Manager

14. Service Broker Tasks(cont.) 4 Service Registry 4 Salutation Manager contains a Registry to hold information about Services. 4 Registry stores information about Services connected to the Salutation manager. 4 Registry many optionally store information about Services that are registed in other Salutation Managers.

15. Service Broker Tasks(cont.) 4 Service Discovery 4 Salutation manager can discover other remote Salutation Mangers and determine the Services registered there. 4 Compare a required Services type(s), as specified by the local Salutation Manager, with the Service type(s) available on a remote Salutation Manager.

18. Mapping Bluetooth SDP to Salutation APIs 4 Assume that the Salutation APIs are implemented on top of the Bluetooth service discovery. 4 Mapping will show how SDP attributes can be passed in the Salutation APIs 4 Assume that the Salutation Manager can be mapped directly to the SDP protocol using a Bluetooth specific Transport Manager 4 SDP is replaced by the Salutation Manager, with the Salutation Manager mapping its functionality to SDP protocol

19. General Mapping Assumptions 4 SDP is a service manager 4 Service requests by LocDev are accessed through Salutation slmSearchCapability() and slmQueryCapability() 4 slmRegisterCapability() and slmUnregisterCapability() APIs call will be mapped on the RemDev side to support dynamic registry of services

20. Salutation API mapping 4 Configuration 4 Model Diagram 4 Mapping

21. Configuration 4 Use of the salutation APIs as the entry point to SDP. 4 No other changes have been made to the Bluetooth model

23. Mapping 4 This mapping uses the functional definition of the salutation APIs, but not the parameter values. 4 The API becomes a vehicle for passing the SDP parameters to the Bluetooth SDP Manager 4 The SLM-ID and Service Description Records parameters of the Salutation APIs are replaced with the appropriate SDP parameter values 4 parameters defined by SDP primitives are passed without modification to Bluetooth SDP manager via the Salutation API format

27. Configuration 4 Use of the Salutation Manager(SLM) in both LocDev and RemDev to provide the service the management functionality of SDP 4 SLM generates appropriate SDP protocol through its TM, handling it off to L2CAP layer

29. Mapping 4 LocDev and RemDev use the Salutation APIs to access their respective Salutation Managers. Bluetooth Service Discovery Protocol flows between the LocDev and RemDev Salutation Managers 4 Two transformations 4 slmSearchCapability() SDP_ServiceSearch 4 slmQueryCapability() SDP_ServiceSearch & SDP_ServiceAttribute

30. Capability Search 4 Salutation Manager maps the Functional Unit Description Record to a ServiceSearchPattern attribute 4 Salutation Manager makes an L2CAP connection with a Bluetooth RemDev and sends the Service SearchPattern to the RemDev in a SDP_ServiceSearchRequest 4 RemDev Salutation Manager returns a SDP_ServiceSearh Response to the LocDec Salutation Manger if there exists registered services with the ServiceSearchPattern 4 When all RemDevs have been contacted, the LocDev SM builds a list of device Ids returning positive reponses and return them as SLM-IDs

31. Capability Qeury 4 LocDev SM maps the Service Description Record to a ServiceSearchPattern. SM then makes an L2CAP connection with the Bluetooth RemDev represented by the SLM-ID passed, and sends the SeviceSearchPattern to the RemDev in a SDP_ServiceSearchRequest 4 RemDev SM sent back to LocDev SM a list of service record handles for the registered services which matches the ServiceSearchPattern

32. Capability Query (cont.) 4 LocDev SM selects one of the service handles returned, maps the Service Description Record to an AttributeIDList attribute and sends them to the RemDev in a SDP_ServiceAttributeRequest 4 RemDev returns a SDP_ServiceAttributeResponse containing an AttributeList identifying a list of attributes and their values for the requested service record 4 continue doing this until all the record handles been done

33. Mapping Bluetooth SDP to Jini APIs 4 Assume that the Jini APIs are implemented on top of the Bluetooth service discovery. 4 Mapping will show how SDP attributes can be passed in the Jini APIs 4 Assume that the JLS can be mapped directly to the SDP protocol using a Bluetooth compatible transport layer(configure TCP/IP over bluetooth) 4 SDP is replaced by the JLS, with the JLS mapping its functionality to SDP protocol

34. Conclusion from paper

35. Personal Conclusion 4 Mapping the JLS functionality to SDP protocol will be more expecting
