BASIL (Basic Architectural Semantics in LOTOS)

See the download page to obtain this program

Description

These files generate OSI (Open Systems Interconnection) service specifications in LOTOS. Both connection-less and connection-oriented services are handled. See Template-based specification in LOTOS and Relating Architecture and Specification for more details. Be warned that macros in this package are very intricate! The work embedded in this package has essentially been superseded by SAGE (Service Attribute Generator).

Usage

As an example, consider a connection-oriented service with the following characteristics:

• Either user may initiate a connection with primitives:

    ConReq (Addr1, Addr2)
    ConInd (Addr1, Addr2)
    ConRsp (Addr)
    ConCnf (Addr)
  

• Either user may initiate normal data transfer with primitives:

    DatReq (Data)
    DatInd (Data)
  

• Either user may initiate expedited data transfer with primitives:

    ExpReq (Data)
    ExpInd (Data)
  

• Either user may initiate disconnection with primitives:

    DisReq ()
    DisInd ()
  

The BASIL description required to define this service is as follows:

  include(basil.m4)

  divert

  co_serv_spec(
    CO,
    ConReq(Addr1,Addr2) ConInd(Addr1,Addr2)
    ConRsp(Addr)        ConCnf(Addr)
    DatReq(Data)        DatInd(Data)
    ExpReq(Data)        ExpInd(Data)
    DisReq()            DisInd()
  )
