- Five Reasons to Adopt Layer 2 Ethernet Switching Over DWDM Networks Now
- A new network is emerging for delivering media-rich and bandwidth-hungry content, applications and services. Traditional SONET Synchronous Optical NETwork/SDH Synchronous Digital Hierarchy architectures, developed for the narrowband world of a generation ago, are overloaded. Such practices as stacking SONET/SDH rings to increase capacity are complex and costly, while Ethernet-over-SONET/SDH protocol...
