That's the main finding of research out this week by ISP izR Solutions, which spoke to 1,000 SMEs with over 250 staff and multiple sites. Only 49.5 percent said they have heard of MPLS, which is generally a way of speeding up and making more efficient IP VPNs.
Already around a quarter of respondents use MPLS but 42 percent said they won't need it in the future, and 8.5 percent said they don't use it when in fact they do -- highlighting the confusion in some IT and telecoms departments.
IP VPNs that use MPLS are now common offerings from many network operators such as AT&T, BT/Infonet, Equant, NTT and Sprint. They generally mean assured quality of service for user organisations.
