Additionally, the ES-4826 has 20 10/100/1000 RJ-45 Ethernet ports, four combo ports (10/100/1000 plus SFP), and two 10 Gigabit Ethernet (GE) XFP ports.

Networking companies create Metro Ethernet Forum, June 12, 2001 Atrica releases 100-Gig Ethernet metro core switch, May 15, 2001 Metro Networks Cut Costs, Complexity, June 5, 2000 ...

To overcome Ethernet's current limitation of 10 Gbps in metro aggregation applications, metro networks are built by layering Ethernet over DWDM systems, which rely on pre-provisioned point-to ...

The problem, however, is that many metro rings rely on the more vulnerable first-mile connection. “Once you get on the Gigabit Ethernet ring, the metro area network, you should be quite safe.

But the 3750 Metro switches should further enhance Cisco’s competitive standing against rivals like Nortel Networks Ltd., Foundry Networks Inc. and Extreme Networks Inc., Perrin said.

RPR uses Ethernet switching and a dual counter-rotating ring topology to provide SONET-like network resiliency and optimized bandwidth usage, while delivering multipoint Ethernet/IP services.

The five-port IP67 Sealed Industrial Ethernet Switch (ET-5RS-IP67) features Real-time Ring capability for superfast switchover on network failure to keep the system up and running.

Aiming to get a big piece of that, Force10 rolled out the S4810, a 1RU top-of-rack switch that features 48 dual-speed 1/10G SFP+ ports as well as four QSFP+ 40G Ethernet uplinks. The switch ...
