CIP over ATM (RFC 1577)
RFC 1577 support is also known as Cl assical IP (CIP) over ATM. CIP is provided as a
path for controlling multiple Broadmore 1750s when IP connectivity over Ethernet is
not available to all of the installed Broadmore 1750s. Control signals are sent to a
Broadmore 1750 o ver the ATM if the Broadmor e 17 50 is n ot on th e Eth ernet with th e
control station. As a prerequisite, the configuration process must be completed.
Configuration forms the Broadmore 1750s into a subnetwork, with either an ATM
switch or workstation designated the server and others designated as clients. The server
maintains a Logical IP Subnetwork (LIS), which cross-references logical IP addresses
to ATM addresses. When the control station sends IP traffic (e.g., control signals) via
the subnetwork IP address to a Broadmore 1750, the server us e s LIS data to tell the
sender an equivalent ATM address to use in place of the IP address. The IP datagrams
are then sent over the ATM network to the desired Broadmore 1750, which takes
appropriate action and responds. The control station has full communications with the
Broadmore 1750 over ATM/Ethernet. Control is identical to control over Ethernet, and
the ATM control path is essentially transparent to the user.
