EDITORIAL The data equivalent of driving around the M25 at rush hour A nyone who does much driving in the UK cannot have failed to notice that the road networks are in quite a mess. Traffic jams are a serious blight on business and productivity in the UK, and huge amounts of work is if we are to improve things and it is also necessary to re-think how we get around or indeed if we need to travel in the first place.

Daniel J Sait, editor in chief, ATM As I started writing this column, new research from R&M highlighted the bottlenecks that will be seen in many local data networks in the future. Local area networks in many existing office buildings are reaching their limits in terms of performance, which should come as a shock, but, to be honest I am not that surprised. R&M estimates that around 80% of the office buildings and functional buildings in western industrialised countries were put up before 1990. As the company points out, the structured cabling in these buildings also usually dates from when the buildings were built. At that time, the LAN was designed for a maximum transmission per formance of one Gigabit Ethernet! If office networks are to remain usable for the next 20 years, they will require a performance of ten times this at 10 Gigabit Ethernet. Crucially, the cabling of offices and buildings cannot be expanded at the same breath taking speed at which IP traffic is growing.
