PARC has pioneered many technology platforms, from Ethernet to the graphic user interface and shared, distributed, ubiquitous computing and has been an enabler of the telecommunications industry and other industries as well.
Bob Metcalfe briefly reviews the history and innovations of PARC in this video.

Carrier Ethernet enables service providers to deliver Ethernet access through their phone networks. Today’s surge in the number of carrier Ethernet access providers, new markets, new applications and application-oriented SLAs, optimized mobile backhaul, delivery of cloud services, and other requirements of this increasingly popular service have led to new demands for new capabilities.
The CE 2.0 standard as defined by the Metro Carrier Ethernet certifying body calls for the expansion of the original standard’s three services to eight. The new standard also calls for new performance goals, interconnections, and manageability for service providers.
Juniper’s CE 2.0 certification enables its service provider customers to certify that their E-Line, E-LAN, and E-Access services are compliant with the CE 2.0 specifications. Because it is a continuation of the original CE certification program that began in 2005, Juniper customers can move ahead without disruption.
The MX Series 3D Routers and Modular Port Concentrators (MPCs) are Key to Juniper's success in obtaining early certification. The ability to flexibly scale users, services, and bandwidth, simultaneously make them uniquely well qualified to deliver expanded Carrier Ethernet services.
Free market advocates dwell on the innate creativity and dynamism of a competitive economy – it’s the way nature works, after all. But it takes time for a healthy ecology to emerge from a tangle of weeds and, in the fast-evolving IT landscape, you sometimes get groups of competing vendors realizing that, for a more solid foundation, there’s a real need for common standards or definitions.
That’s what happened in 2001, when a group of network vendors and providers saw that, while Ethernet had risen to dominate the enterprise LAN space, it had also resulted in islands of data that could only be connected via relatively inflexible WAN protocols. A typical enterprise might have several Ethernet LANs at sites across town – so what was stopping them from linking via Ethernet itself to create one big corporate Metro Area Network?
In the late nineties, the IEEE developed 1 and 10Gbps Ethernet standards that could now physically reach across a metro area but nothing was changed to make it suitable for business or carrier-class wide area networking. It offered an attractively simple technology with ever-increasing bandwidth, but needed additional attributes if it was to compete with relatively sophisticated WAN technologies like Frame Relay and ATM.

The MetroEthernet Forum (MEF) has announced the first 20 vendors to offer Carrier Ethernet 2.0 certified products. They are Accedian, Altera, BTI Systems, Ciena, Cisco, Cyan, FibroLAN, Huawei, Infinera, Juniper Networks, MRV, Omnitron, Overture, PT Inovacao, Pulsecom, RAD Data Communications, Telco Systems, Tellabs, Transition Networks and Transmode. MEF board chairman Ihab Tarazi said the benefits include an increase in the number of access providers in the Ethernet community, new markets for regional providers, application-oriented SLAs, optimised mobile backhaul and cloud service delivery.
The new CE 2.0 extends the original purpose of Carrier Ethernet with added features including: multiple classes of service, greater manageability and easier interconnect for eight standard services types, enabling new levels of efficiency for mobile backhaul, making it easier for large numbers of access providers to join the Carrier Ethernet community and establish Carrier Ethernet as a business class cloud service carrier.
