Upgrades
to Cambridge CCN
Audience:
School Staff
There
will be a short service break on Tuesday 4th August 2009 between
18:00 and 21:00 hours.
This
break is to allow for the upgrade of equipment in preparation for Primary school
CCN bandwidth upgrades. The work has been categorised as low risk and can
readily be rolled back should problems occur.
In
technical terms, the work is as follows:
The
work is to spread out the circuits across the existing Aggregation Router
interface to make use of the additional ports / buffer limits; there is no new hardware etc,
so it is effectively like repatching the circuits.
Each port has a 1.4mb buffer limit, so we are spreading the circuits out to 1 in
every 8 ports, so the circuits stand no chance of exceeding their buffer limit.
Worse case scenario is they can back out the circuits to their original /
existing ports.
Should
you have any queries regarding this information please contact the ICT Service
Helpline 08450 450 973.
