The advent of its fatter version is opening up the transfer of WAN data from ATM, frame-relay or packet over SONET/SDH to a potentially more efficient and cheaper method. Even Andrew Rufener, ambassador to the ATM Forum and director of technology...
Existing metro networks have used Sonet/SDH, an expensive but reliable network designed to carry voice traffic reliably on ring networks. Until now, metro networking has come at the cost of of a major step change from Ethernet to more expensive...
Nothing here, it would seem, to challenge the incumbent technologies, most notably Sonet/SDH (synchronous digital hierarchy), a transmission standard used by most of the world's carriers today. The cost to the carrier of installing a Gigabit...
However, arguments about the user experience, battery life, et cetera are inconsequential when carriers and end users are demanding HSPA. In many, national 3G coverage is already in place, with 2G/Edge confined to legacy-device support only.
Companies will have to rewrite some of their legacy code if they want to take full advantage of the move to multi-core computing. There's a lot of very old code out there so there will be quite a disruption to legacy code to take advantage of multi...
According to a study from Infonetics Research, broadband internet, metro ethernet and IP VPNs are the technologies causing the highest growth in IP traffic for telecoms carriers in Asia-Pacific, Europe and North America - and thus should be...
