Native ATM Services

Semantic Description

semantic
Semantic…
  • Independent of any programming language or operating system.
  • Not an Applications Programming Interface (API).
native atm services include
Data transfer, including both reliable and unreliable data delivery, using the ATM layer and various ATM adaptation layers.

Provisions for setting up switched virtual circuits.

Distribution of connections and associated data to the correct application, or entity.

Provisions for setting up permanent virtual circuits.

Traffic management considerations, including traffic types and quality of service guarantees.

Provisions for local participation in network management.

Native ATM Services include…
one shot state machine
One Shot State Machine
  • Object being modeled is a connection between two or more parties across an ATM network, which occurs once in time.

diagram conventions
Diagram Conventions
  • The rectangles are entities.
  • The circles are attributes of the attached entities
  • The diamonds are relationships between the entities.
  • The numbers on either side of the diamond denote the cardinality of the relationship (e.g. one-to-one, many to one).
null a0
NULL (A0)
  • No entity-relationship diagram for this state.

entity relationship diagrams
Entity-Relationship Diagrams

Entity Relationship Diagrams show

  • The data structures required to implement Native ATM Services.
  • The information available to the application, through the interface primitives.
data plane location of data
Data Plane (location of data)
  • Memory space that the operating system kernel manages
  • Memory space that the application manages
  • Hardware (e.g. the ATM adapter card, the video card, the sound card, a private data bus)
receiving data primitives
Receiving Data Primitives

Only one of the following implementations need to be supported in a conforming system.

  • Polling Implementation
  • Blocking Implementation
  • Messaging Implementation
