Agenda

• What are Service Connection Points?
• Why are they used?
• How do they work?
• When can they be used?
• Example

3
A Service Connection Point is...

• An object that resides in the Active Directory
• An object that contains information about a
  service

• NOT a physical entity

4
A Service Connection Point is used by...

• A service, for publishing information about
  itself

• A client, for getting the information necessary
  to bind to the service

5
Using Service Connection Points provides...

• Location Transparency
• Clients need not know names or locations of
  existing services
• No stale binding

6
How it works (server side)

• Publish service connection point on first
  start-up
• Store service connection point ID in registry
• Update service connection point on subsequent
  start-ups

7
How it works (client side)

• Asks Active Directory for a list of available
  services to choose from
• Retrieve binding information for selected service
• Store service connection point ID
• Use stored ID to reconnect to service on
  subsequent start-ups
