Communication access control system

A method for controlling messaging, comprising:

• receiving, via a processor at a messaging service facility, a request to make a connection within the messaging service facility;
• and
• via the processor, creating a link to make the connection, the link being selected from:
• a C-link to connect an output address of a first access control cell to an input address of a second access control cell, wherein each of the first and second access control cells are read-write cells;
• an F-link to connect a forwarder address to an input address of an access control cell, both the forwarder address and the input address being known by a user requesting the connection;
• and
• a Q-link to connect an output address of an access control cell to a queue address, both the output address and the queue address being known by a user requesting the connection;
• wherein the access control cells and the links are hosted on a computer system having the processor and permanent memory.

A computer program product comprising a non-transitory, tangible computer readable storage medium having computer readable instructions embodied thereon, the computer readable instructions, when executed by a processor of a messaging service facility, cause the processor to:

• receive a request to make a connection within the messaging service facility;
• and
• create a link to make the connection, the link being selected from:
• a C-link to connect an output address of a first access control cell to an input address of a second access control cell, wherein each of the first and second access control cells are read-write cells;
• an F-link to connect an input address of an access control cell to a forwarder address that is known by a user requesting the connection;
• and
• a Q-link to connect an output address of an access control cell to a queue address that is known by a user requesting the connection;
• wherein the access control cells and the links are embodied on the non-transitory, tangible computer readable medium.
