What is
MPOA (MultiProtocol Over ATM)?
MPOA (MultiProtocol
Over ATM) is a protocol developed by the ATM Forum. More
complex than NHRP he uses the techniques described in the previous sections by
uniting and complementing to achieve IP packet transport or other protocol packets,
such as IPX, over an ATM network interconnection. The road can be determined
either by a centralized route server solution type, either by a distributed
solution using the PNNI or NHRP protocols.
The role of MPOA is always to find the corresponding ATM
address to open a direct connection, or shortcut, between two ATM stations that
know at the outset that by their IP address.
The two components of MPOA are:
• MPC (MPOA Client), which, at the request of a client,
research the best way to open a virtual circuit with a customer who knows the
IP address.
• MPS (MPOA Server) located in a router, which, using a conventional routing,
such as RIP (Routing Information Protocol), OSPF (Open
Shortest Path First), etc., routes NHRP query requests correspondence.
