Dual link: Inline Installation
In this topology, one SCE 2000 is connected inline in two full duplex, GBE links.
In case the two links are load-shared, asymmetrical routing might occur, and some of the flows
may be split, i.e. the upstream packets of the flow go on one link, and the downstream packets go
on the other link.
When installed in this topology, the SCE 2000 completely overcomes this phenomenon, and
provides its normal functionality as if asymmetrical routing were not occurring in the two links.

This topology supports both monitoring and control functionality, and is referred to as “inline”
connection mode.
