The Host Environment

  The TCP is assumed to be a module in an operating system.  The users  access the TCP much like they would access the file system.  The TCP  may call on other operating system functions, for example, to manage  data structures.  The actual interface to the network is assumed to be  controlled by a device driver module.  The TCP does not call on the  network device driver directly, but rather calls on the internet  datagram protocol module which may in turn call on the device driver.
  The mechanisms of TCP do not preclude implementation of the TCP in a  front-end processor.  However, in such an implementation, a  host-to-front-end protocol must provide the functionality to support  the type of TCP-user interface described in this document.
