Network Bandwidth

Bandwidth and connection speed

Bandwidth describes the speed at which data moves between your computer and the Internet. The bandwidth of the 'core network' has now been increased to 10 Gigabits per second. This equates to about 1,200 times the speed of 'fast broadband' and the network carries all of the inter-departmental traffic and all the data that travels between PCs, servers and our data centres. A major upgrade of the core network equipment has also been undertaken, especially in the Towers to cater for the expanding network and services in those buildings.

With the upgrade of our external network connection to our Internet provider, the London Metropolitan Network, we are now able to offer twice the bandwidth to halls of residence, compared with the provision at the start of the 2006-07 academic year. This provides a much improved Internet experience for students in study bedrooms.

Demand for bandwidth from student residences continues to grow and Information Management and Technology will monitor traffic patterns and traffic volume, and continue to use control measures to provide a fair balance between academic and non-academic use of the network.

The School's IT systems, including access to the Internet, are provided for students to pursue their studies and for staff to carry out their work. The widespread use of file sharing software for social use has adversely affected network performance to Halls. Residents can reduce the impact of this by configuring their file sharing software so that it doesn't act as a 'supernode', reducing the number of concurrent uploads to one, and reducing the upload bandwidth where possible. This will help to improve the network service for all users.

During weekdays bandwidth control measures will be applied during three time periods:

'Peak time' during the daytime (8am to 6pm) where a lower priority is given to non-academic use.
'Evenings' (6pm to 2am) and weekends (8am to 2 am) with medium priority set for non-academic use.
'Off-peak night-time' (2am to 8am) with higher priority given for non-academic use.

 


Daytime "Peak" Evenings Overnight "Off-Peak"

08:00 - 18:00 18:00 - 02:00 02:00 - 08:00

 Key:


Focus on Academic use. E-mail, access to LSE resources, conventional web-browsing all available. Other high-bandwidth usage may be restricted.

Academic use is prioritised but other non-academic use, including social networking (Facebook), iTunes, YouTube, Skype, and recreational use is less controlled.

Fair balance between academic and recreational use.

Bandwidth for file-sharing using 'peer-to-peer' applications (such as BitTorrent and eDonkey) and file-sharing sites (such as megaupload.com) use up considerable network bandwidth, often at the expense of others. These activities are tightly managed, particularly when academic usage is given priority. A collection of 'non-academic' applications have some restrictions applied during peak periods but are less restricted during the evenings, at weekends, and overnight. Applications include social networking (Facebook), audio and video downloads (iTunes, YouTube), personal communications (Skype), and recreational (Second Life, gaming). This group of applications and the applied controls are monitored with the aim of providing sufficient bandwidth for responsible, legitimate usage without impacting provision for core academic applications. All other traffic, including all legitimate academic use, has no bandwidth restrictions applied within the overall halls bandwidth allocation.

--Four Students Reach Settlement Agreements with RIAA

(1/2 May 2003)

The Recording Industry Association of America (RIAA) has reached settlements with four college students it says were running illegal music file sharing services. The students will each pay the RIAA between $12,000 and $17,500. Attorneys for a Princeton University student involved in the case said their client had reached a settlement with the RIAA but had not admitted guilt.
