West Kentucky and Tennessee Telecommunications Co-op taps Clearfield for FTTH
West Kentucky and Tennessee Telecommunications Cooperative (WK&T) is deploying the FieldSmart fiber management and protection platform from Clearfield, Inc. (NASDAQ:CLFD) in the central office of its fiber to the home (FTTH) roll out, according to Clearfield.The project uses $123.8 million in loans and grant money from the Broadband Initiatives Program (BIP), part of the American Recovery and Reinvestment Act broadband stimulus effort. WK&T’s deployment is the largest stimulus-funded project in the country focused on wireline services, Clearfield asserts.WK&T plans to use the FTTH network to offer advanced telecommunications services to 21,000 homes and businesses across the company's nine-county service area in west Kentucky and northwest Tennessee. Construction has begun on three of the 22 exchanges within the serving area. The project should be completed within the next three years."We conducted a thorough and stringent process of selecting partners for the stimulus award at West Kentucky,” said Ray Cantrell, CTO of WK&T. “Clearfield's dedication to superior functionality and technology at a fair price were the prime factors in our selection. "Not only do the panel systems allow us the flexibility to deploy in multiple environments, but the cassettes offer many different features that we feel are an added value."

Ensuring cloud computing performance on data communications networks: Part 1
Cloud computing promises to reduce IT expenditures, increase network flexibility, and streamline communication infrastructure. This is the first in a series of three articles in which we will examine communications technologies as key enablers that can make cloud computing a reality. Specifically, we will look at protocols, traffic management, and the control of wide-area communications and how the application of industry-standard techniques can assure network designers robust performance in their cloud offerings.In this article, we’ll define specific communications reference points (RPs) within cloud computing networks so that software designers and network architects can better understand and address specific problems. Each RP presents unique requirements and challenges for creating, maintaining, and managing connectivity. Creating proper communication paths on the network and configuring them correctly at these RPs, or interfaces, will maximize cloud performance. The communication RPs will be defined individually; for each RP we will analyze the type and characteristics of the data communicated, describe the expected traffic patterns at the RP, and discuss the reliability requirements, the need (or lack thereof) for real-time traffic delivery, quality of service (QoS), and other characteristics of communication technologies, such as security. The applications cloud computing supports may affect millions of transactions and billions of dollars of commerce. They are relied upon for decision making, planning, contracts, and legal obligations. If the communications channels are unreliable, the impact can be far-reaching and costly. Therefore, accurate, timely, and secure communications are required for many cloud applications -- and sometimes the applications themselves must account for these potential communication issues. Cloud RPs enable cloud application developers and service providers to consider these issues in a more comprehensive way.For example, if the communication channel adds significant delay or delay variation, then application performance may be affected. Likewise if the communication network encounters congestion, it could have significant negative impacts on cloud service users. Many cloud applications require significant bandwidth. If bandwidth is inconsistent or constrained, then cloud applications may be impaired. In severe situations, time-sensitive transactions may be affected by bandwidth constraints.Cloud network designers must contend with three major factors that can affect performance – QoS, security, and reliability. First, QoS can be assured via a number of controls so that appropriate treatment can be applied to packets depending on their importance. QoS metrics help monitor such service elements as traffic profile (e.g., average and peak rate and burst size) and delivery (e.g., delay, delay variation, and dropped and “errored” packets).Second, security must be addressed within the cloud itself and at client devices that attach to the cloud. Encryption and authentication mechanisms therefore are recommended for cloud communications.Finally, network reliability is also critical. We all know how significantly our work is affected when access to our corporate e-mail or servers is unavailable. Cloud networks require even higher availability standards; therefore, communication service management protocols are required to assess the performance and health of the communications channels within the cloud network.The technology and protocols behind passing data traffic among remote resources are complex and the cloud service provider often may not own the data communications equipment and protocols used in the process. This situation will change as more cloud service providers build their own networks. Yet in both cases, it is important for a cloud provider to define requirements for communication channels in an unambiguous and industry-standard way either to the communication provider or for its internal configuration. That is why understanding the communications requirements at each RP will help to design a seamless and consistent cloud network.

Costa Rica Looks To High -Speed Future
As Latin American telecoms giants América Móvil and Telefónica finally launch mobile services in Costa Rica, the region's last mobile monopoly is facing a new era. BMI has long believed that competition will revolutionise Costa Rica's telecoms market, and developments thus far have proved this to be true. However, while much has been achieved over the four years since Costa Rica signed the CAFTA-DR that required telecoms market liberalisation, BMI believes there is plenty more still to be done.Liberalisation of Costa Rica's telecoms market has been beset by delays and difficulties, but the launch of América Móvil's Claro and Telefónica Movistar is a milestone for the market. The two companies compete fiercely across Latin America, and BMI expects their presence in Costa Rica will have a positive impact on market growth, consumer choice and prices. It is unfortunate that mobile number portability (MNP) was not available at the same time as the operators' launches, but BMI believes this will be little impediment to either operators' prospects.Starting To Reach Potential Costa Rica Telecoms Penetration Rates (%) f = BMI forecast. Source: BMI, Operators, Sutel .Incumbent ICE responded well to the advent of competition, launching 3G services and a prepaid platform, and expanding the number of lines available to Costa Ricans. These developments were almost certainly driven by the knowledge that competition from large international investors was on its way, although some developments were already in the pipeline. While there have been some reports of congestion on the operator's network, this highlights the pent-up demand for mobile services and is a positive sign for Movistar and Claro as they begin to build their brands. Initial launches by both operators are limited to certain areas of the country, but expansion is expected to be rapid, and BMI expects high interest from potential subscribers looking to acquire their first mobile handset. Costa Rica's low mobile penetration rate is set to soar as competition makes its mark.In the years since Costa Rica began opening its telecoms market to competition, much has changed in the wider telecoms market. Data use has soared, smartphones have become more affordable and operators are less reliant on traditional voice services to drive revenues. ICE announced in October 2011 that it would build-out an LTE network by the end of 2012, helping it to cater to the already-strong demand for mobile data. While BMI welcomes the announcement, we believe there is potential for upgrading 3G networks to serve to demanding data users and getting the most out of the company's investments so far.Like the rest of Latin America, and certainly Central America, there is great potential for new services over mobile networks, most importantly mobile broadband. BMI believes that dedicated mobile broadband services will account for a high proportion of total broadband connections across Latin America. América Móvil and Telefónica's experience in offering these services and the range of content and devices on hand make them key drivers of Costa Rica's mobile broadband future.BMI also expects mobile content to become a greater part of the Costa Rican mobile experience. Faster networks bring opportunities to offer a wide range of content, and both Telefónica and América Móvil have experience and a wealth of existing content that can be brought quickly to the Costa Rican market. Their large scale means they can offer services at a loss and bulk-buy the latest devices, meaning competitive prices for subscribers. Costa Rica was far behind its regional peers in terms of speed and availability of service, but is now set to catch up quickly.While the mobile market will continue to evolve, the focus has turned to the broadband network. ICE's 95% fixed-line coverage is a great basis for broadband expansion, although high-speed services will require new network deployments. A public consultation on the national broadband strategy will begin on November 14 2011.Not only will fibre-optic networks offer the high-speed broadband that Costa Rica is looking for, but it will also allow new products to be launched. IPTV, VoIP, OTT services are just some of the new products ICE and its rivals could offer once higher capacity networks are available. Javier Pereira of Columbus Networks points out that Costa Rica already has a strong existing network and access to three international submarine cables, but does not use the full capacity available.The national broadband strategy aims to increase broadband penetration at 2Mbps from 6.2% to 10% by 2015, a target BMI believes is achievable. Currently only 40% of households have access to a broadband connection between 512Kbps and 1Mbps.And what of ICE? The incumbent remains in government hands, with no indication thus far of plans to privatise part or all of the operator. BMI would advocate privatisation in order to enable all companies to compete on a level playing field and ensure ICE's continued strong presence. ICE's response to upcoming competition has been positive, launching new services before its future rivals could in order to shore up its position. Nevertheless, internationally-backed rivals have many advantages, including strong financial backing and a wealth of technical expertise to help them capture their share of the different segments of Costa Rica's telecoms market.BMI retains a positive outlook for Costa Rica's telecoms market, particularly as competition has arrived in the mobile market, where we expect strong growth. A new focus on broadband will bring long-term benefits and will maintain Costa Rica's attractiveness to outside investors.
