InterPhase4539 memo(1)

Basic Knowledge about the InterPhase 4539:
1.Client:
  A client is a host logical entity that dialog with Link Manager
2.Link:
  A link reprents a communication channel beetween a client and the Link Manager
3.Session:
  1)A session defines a logical channel between a client and the Link Manager.
  2)More than 1 session can be mutiplexed into 1 link.
  3)All primitive exchanges between the application and Firmware OS is provided by a session
  4)To establish a connection with remote node or dialog with protocol in iWare OS, an application must open a session with Link manager
4.Driver Module :
  in a protocol stack,the characteristic of the lowest protocol is that its message can not be encapsulated into message of lower protocols. Its message are sent out to the network directly. This type of protocol is called Driver module.
  E.g ATM,MTP2
5.Link Manager OverView:
  1)Session Management
  2)Configuration DataBase Management
    -Protocol and Connection Parameters(Defination of profile)
    -Defination of Protocol Stack
  3)Connection Management
    -Connection Establishment
    -Protocol Binding
  4)Message Routing
    -Data Packets
    -Control Message
    -Supervision    
6.Connection profile
  -In order to set up an outgoing or incoming connection ,do follow:
  1)Establish a session with Link Manager
  2)Gather into profiles the sets of working parameters for any protocol involved in the connection
  3)Optionally define a profile stack which depicts organization of protocol modules and the profiles usage.....
  4)add the profiles and optionally profile stack defination into the Link manager Database
7.Link Manager Database
  -Each profile,profile stack is stored in the Link Manager database and identified by string name.
  -the string name can be used as entry index.Entries are available to all clients.
  -So choose name carefully to avoid override.
8.Activation/Deactivation of protocol modules
  -Link manager determine which protocol layer(s) to activate when making a connection
9.profile connection mode:
  -OUTGOING
  -INCOMING
  -BOTHWAYS
  -ANYWAY
