→Multiple LNS links to BT, TT and mobile
|
We operate multiple LNSs connected to multiple links in to carriers. This is partly for redundancy (if one of the LNSs or links break) and partly for load (to handle over a gigabit, the size of each link).
From early 2012 we had four main LNSs handling all traffic from BT and TT, in April 2016 this was expanded to seven, and in 2017 nine LNSs in total plus the test LNS
Normally we run with n-1 live LNSs and so this leaves one as a backup in case of failure.
