Enterprise network engineers upgrading their Ethernet backbones, and service provider network engineers deploying metro Ethernet and triple-play services, share a common challenge. When scaling packet ...

Circuits as WAN connections battled successfully against packets for years because they guaranteed bandwidth, no matter what. If you bought a T-1 circuit, the service provider nailed up 1.5Mbps from ...

As we mentioned last time, there was an entire industry built around using TDM bandwidth efficiently due to the compelling economics of building corporate private-line networks. By the late 1980s, ...

Electrical switching based data center networks have an intrinsic bandwidth bottleneck and, require inefficient and power-consuming multi-tier switching layers to cope with the rapid growing traffic ...

Data centre networks are increasingly constrained by the capacity, latency and energy demands of conventional electronic packet switches. Optical switching technologies offer a compelling alternative, ...
