Classical IP over ATM Concepts

RFC 1577, Classical IP and ARP over ATM, describes an administrative entity

within an ATM network called a logical IP subnet (LIS). Each ATM LIS consists

of multiple network devices -- hosts and routers -- connected to the ATM network

and configured with interfaces to the same IP subnet.

Each LIS operates and communicates independently in an ATM network. A host

connected to an ATM network communicates directly with other hosts in its own

LIS. To communicate with hosts in another LIS, the host must use an IP router.

This router can connect to multiple LISs.

An ATM LIS must meet the following requirements:

• All members of the LIS (hosts and routers) must have the same IP network/

subnet address and mask.

• All members must be directly connected to the ATM network using SVCs.

• All members must access hosts outside the LIS through a router.

• All members must be able to communicate by means of ATM with every other

member of the LIS (that is, the virtual connection topology must be fully

meshed).

Number of bits/second

Number of bits/ATM cell

= Number of cells/second

For example:

100,000,000 bits/s

424 bits/cell

= 235,849 cells/s
