Ethernet Alliance Promotes 200/400

January 12, 2018

The Ethernet Alliance is lauding the fact that the IEEE 802.3 Ethernet Working Group has approved the IEEE 802.3bs, Standard for Ethernet Amendment: Media Access Control Parameters, Physical Layers, and Management Parameters for 200 and 400 gigabit per second operation. The specifications are expected to help address in a cost efficient and scalable way the growing bandwidth demands of collocation services, data centers, high-end applications, internet exchanges, and service provider networks.

The Ethernet Alliance, which earlier this month issued a press release in support of the move, commented: “IEEE 802.3bs represents a transformational moment in the move to next generation of networks. The delivery of 200G and 400G is arriving just in time to meet growing needs for reliable, high-speed connectivity from a diverse array of applications and markets.”

John D’Ambrosia, chairman of the Ethernet Alliance and senior principal engineer at Huawei, continued by saying: “The exceptional effort resulting in the completion of this standard is only the start of the industry’s investment in the networks of tomorrow. We’ve laid a firm foundation for 200G and 400G with our early interoperability demonstrations and plugfests, but it’s time to kick things into high gear. The real work of testing and verifying multivendor interoperability begins now, and the Ethernet Alliance is ready.”

During OFC 2017 in March the Ethernet Alliance demonstrated 400GbE, and it’s planning additional interoperability test events and demonstrations. Alliance members include component and system vendors, industry experts, and university and government professionals. That includes principal members Amphenol, Broadcom, Cavium, Cisco, Dell, Finisar, Huawei, Intel, Juniper Networks, Spirent Communications, TE Connectivity, and Teledyne Lecroy.

Ixia’s Jeff Harris, in an August column, wrote: “The 400GE standard is not only four times as fast [as the 100GE one], it will also offer a better economy of scale and a denser configuration, leading to a more attractive price-per-port. A one-rack unit with 32 ports of 400GE will be less expensive to build than a two-rack unit with 64 ports of 200GE.”
