Group 4 Securicor to save £70,000 a year with bandwidth tool

Security provider Group 4 Securicor (G4S) is set to save £70,000 a year in additional bandwidth costs with an upgrade that allows it to allocate existing network capacity to critical applications more quickly.

Security provider Group 4 Securicor (G4S) is set to save £70,000 a year in additional bandwidth costs with an upgrade that allows it to allocate existing network capacity to critical applications more quickly.

G4S's network, which incurs £280,000 a year in bandwidth costs, links 42 sites equipped with more than 1,000 PCs. It runs critical applications, such as real-time armoured-vehicle monitoring and real-time monitoring of alarms.

Prior to the upgrade, users were experiencing delays in sending data across the network because of the high number of applications running on the network and the limited bandwidth available, said Vincent Girardin, IT director at G4S.

The company installed hardware from Ipanema, costing £42,000, to monitor the flow of traffic over the network so that the correct amount of bandwidth could be allocated from less important applications to more critical ones.

The biggest challenge was deciding what applications should take priority. Between 2002 and 2007, the criticality of network applications was reviewed, resulting in 15 classes covering all the networked applications.

"We do not often modify the criticality of our applications, but we often have to prioritise certain end-users," said Girardin.
