On June 17th, the IEEE has ratified the 802.3ba standard for Ethernet connections with speeds of 40 and 100 Gbps.
Both Cisco and Juniper have been supplying high performance network equipment which support the above standard.
Cisco for example supports the 100Gbps Ethernet card on its CRS-3 router, while Juniper supports its 100Gbps PIC card on its T1600 Core Router.
As its name suggests, the IEEE 802.3ba standard allows for Ethernet services of 40 and 100 Gbps in both LAN and WAN implementations.
The initial plan for the fastest Ethernet ever was to develop the technology for the 40 Gbps to support high-speed connections between switches and core servers, while for the 100 Gbps speed the plan was to support transport trunks for Internet and Video over IP.
Both standards are applicable for the transport of packets in optical fiber networks.
Of course, as in previous cases, the new standard maintains backward compatibility with the rest of the Ethernet family.
