ISA and ESA hardware

In this section

This section provides an overview of Nokia’s implementation of the virtual ISA.

Note: Virtual ISA MDAs must be configured using the commands described in the 7705 SAR Gen 2 Interface Configuration Guide.

Note: The following conditions apply to the virtual ISA:

Virtual ISAs cannot be intermixed within the same ISA group. This limitation applies to all virtual ISA group types.

Virtual ISA overview

The virtual ISA has no external ports, so all communication passes through the node's virtual datapath, making use of the datapath's queuing and filtering functions like other MDAs.

The actual ingress and egress throughput varies depending on the buffering and processing demands of a specific application.
