W/E: 14 th April 2013. UKBA/Border Force restricted infrastructure: weekly dashboard. OVERALL EXPERIENCE. APPLICATION PERFORMANCE.
High bandwidth utilisation, high WAN latency and high citrix latency is being experienced across a number of mainly “small sites” i.e. those sites with circuits of 2mb or less.
Network RTT - the time required for a network communication to travel from the source to the destination and back.
Data is based on the average across the service hours of 7am – 7pm, Monday – Friday.
Network dispatchers* have been switched off at 47small sites from 7am – 7pm, M – F (6am – midnight for Juxtaposed) as an interim measure to improve network performance .
Investigations have confirmed that Juxtaposed sites have been pointed at the wrong location for SEP updates – a change to correct this is being progressed. Also a new router – to reduce packet sizes - is being implemented this week at Calais.
The RES Wisdom upgrade to reduce network chatter is now targeted for the end of April (precise dates to be agreed).
*(dispatcher refers tothe service which distributes software updates and patches etc to Poise devices).
Top 10 sites experiencing poor network performance
