OIF targets 400G module, Transport SDN
The Physical and Link Layer Working Group of the Optical Internetworking Forum (OIF) launched a new project to define a module interface implementation agreement (IA) for 400G long-haul optical transmission. Also at the OIF’s meeting in New Orleans last week, members agreed to address carrier requirements for transport software-defined networking (SDN), and neighbor discovery for Ethernet external network-to-network interfaces (E-NNI).“There is nothing in the standards market today to use as a starting point to support 400G module solutions,” said Karl Gass of TriQuint Semiconductor and the Physical and Link Layer Working Group - Optical vice chair. “Definition of a 400G long-haul module provides the industry with technology parameters for near-term component development and implementation strategies.”Meanwhile, the Carrier Working Group members agreed to establish carrier requirements for Transport SDN, detailing transport functions for specific SDN use cases.
“The OIF ecosystem provides carrier members a platform to express their requirements for certain technologies and SDN is certainly one of interest by our carrier members,” said Hans-Martin Foisel of Deutsche Telekom and the OIF Carrier Working Group chair. “Additionally, the OIF has been invited to talk at several industry venues this year on the SDN technology.”At the meeting, members also approved an IA for RSVP Extensions for User Network Interface (UNI) 2.0 Signaling Specification Release 2. This IA contains RSVP-TE extensions for UNI 2.0 signaling Release 2, updating references and related Ethernet code points."OIF standardization efforts helped make the 100G market a great success in the face of broad competition from 40G,” said Andrew Schmitt, optical industry analyst for Infonetics Research, who spoke at the meeting. “And the organization will continue to be an important catalyst for accelerating component availability of future technologies such as 400G, pluggable coherent, or direct-detect 100G."
Alcatel-Lucent provides smart fiber-optic network for Luxembourg utility Creos
Alcatel-Lucent (Euronext Paris and NYSE: ALU) says it is providing a modernized communications network for Luxembourg power utility company Creos. The network uses the systems house’s routing technology to lower costs and enhance the reliability and efficiency of power transmission, Alcatel-Lucent asserts.Alcatel-Lucent has used its IP/MPLS technology to replace Creos’s existing TDM-based communications system to bring a new level of intelligence to its power transmission network – from power generation to the substations. The new technology will enable Creos to consolidate such services as teleprotection, current differential protection, closed-circuit TV (CCTV), and supervisory control and data acquisition (SCADA) systems onto a single network.The ability to converge all services on to one communications network not only enhances operational performance but will also help Creos save the costs associated with managing multiple networks. This includes extending Creos’s intranet to support communications between control centers and the remote substation sites, enabling engineers to remain connected when they visit those sites.Under the contract, Alcatel-Lucent will provide Creos with its 7705 Service Aggregation Routers, with the SAR-8 and SAR-18 variants, as well as the 7210 Service Access Switch and 5620 Service Aware Manager.Interoperability and performance testing with third-party current differential protection equipment was successfully conducted over a distance of 104 km using 10-Gbps and 1-Gbps fiber-optic cable links passing through 11 routers. Alcatel-Lucent asserts that during testing the IP/MPLS technology consistently delivered results of below 5-ms latency across the fiber-optic network and less than 200-µs jitter, meeting the requirements for essential service support such as differential protection and teleprotection.Patrick Colling, communications expert at Creos said, “Creos is an innovative company and we want to utilize the latest technologies to ensure reliability and effectiveness of our business, now and into the future. The new communications system will form the basis of our smart grid and ensure the network is always available to meet demand.”Lynn Hunt, global vice president, utility solutions of Alcatel-Lucent said, “We have proven the performance of our IP/MPLS technology in delivering services such as teleprotection and it allows us to give utility companies such as Creos a more complete view of their network to make power transmission more efficient and cost-effective.”
First Carrier Ethernet 2.0 certified equipment announced
The Metro Ethernet Forum (MEF) announced Tuesday, January 29 that it has awarded the first Carrier Ethernet 2.0 certifications to 20 companies. Certified products include a variety of optical transport equipment.As its name implies, Carrier Ethernet 2.0 represents the second generation of the MEF’s Carrier Ethernet specifications. The new regime includes the addition of support for multiple classes of service, greater manageability and easier interconnect for eight standard service types, and more efficient mobile backhaul. Both products and services can receive certification (see "MEF launches Carrier Ethernet 2.0 certification program").The first 20 companies to have products certified as Carrier Ethernet 2.0 compliant include:Accedian Altera BTI Systems Ciena (six services each on its 3916 and 3930 Service Delivery Switches and its 5150 Service Aggregation Switch) Cisco Cyan FibroLAN Huawei Infinera Juniper Networks MRV (OptiSwitch 906G and OptiSwitch 940 10GbE Carrier Ethernet Demarcation series) Omnitron (iConverter Network Interface Devices) Overture (the Overture 1400, 4800, and 4000) PT Inovacao
Pulsecom RAD Data Communications (the ETX-5300A Ethernet Service Aggregation Platform, ETX-205A Advanced Carrier Ethernet/Mobile Demarcation Device and ETX-203AX Carrier Ethernet Demarcation Device) Telco Systems (the T-Marc and T-Metro product lines) Tellabs (the Tellabs 7100 Optical Transport System and the Tellabs 7300 Metro Ethernet Switch series)Transition Networks Transmode (Native Packet Optical 2.0 hitecture).“CE 2.0 is a difficult accreditation to achieve,” according to Bob Mandeville, president and founder of test lab Iometrix, which is responsible for MEF’s certification testing process. “To be recognized as CE 2.0 certified, each company must pass a suite that totals 634 stringent tests. Over 155 companies are now certified for CE 1.0 and the adoption signs for 2.0 are exciting. The demand for certified products and services is a driving force, and we expect a significant increase in service provider certifications not only from established markets, but also from developing economies in 2013.”“The companies’ achievements are are a testament to their commitment to outstanding delivery for the Carrier market” said Ihab Tarazi, the MEF’s chairman of the board and Verizon’s vice president of global network planning. “Certification will enable service providers to choose equipment vendors with greater speed, clarity and certainty. CE 2.0 Certification marks a significant moment in the life of the MEF and Carrier Ethernet.”
