Keeping latency in check is critical for quality of service (QoS) of demanding Ethernet wireless backhaul, wholesale and business services. Given that Ethernet bandwidth is considered relatively ‘inexpensive’, some providers increase throughput to reduce latency and keep performance within strict SLA tolerances. However, the relationship between bandwidth and latency is anything but simple in packet-based networks, where increasing throughput can sometimes have no effect on delay, or even increase it under certain conditions. This paper explores the key sources of delay, and techniques to optimize latency without consuming excess bandwidth. These guidelines allow providers to use their network resources as efficiently as possible, while assuring the QoS of critical, real-time services. Download Full White Paper Here

What is Dim Fiber?
Optical fiber only partially lit in a fiber optic transmission system (FOTS) employing wavelength division multiplexing (WDM).WDM technology can support a considerable number of wavelengths running simultaneously over a single optical fiber within a cable comprising perhaps a great number of fibers. A dim fiber is one over which not all available wavelengths have been lit and which, therefore, has excess capacity.

Why Dim Fiber?

A dim Fiber customer gets assigned a wavelength in a fiber span that provides flexibility and performance similar to dark fiber with the following benefits:

• Use of fiber span not limited to a specific bandwidth, just a specific wavelength, thus the customer has more control.
• Reduced equipment on the circuit reducing potential outages.
• Reduced equipment on the circuit reducing processing latency.
• Dark Fiber performance at a lower cost.
• Dark Fiber performance with a variety of contract terms closer to customer experience with lit services.

Why CFN Services Dim Fiber Solutions?

• With CFN Services as your partner on your dim fiber plans – CFN will manage and monitor the health of the fiber span via other circuits running on the same fiber span.
• Dim Fiber allows wireless operators to take advantage of the owners economics and cost efficiencies of a managed backhaul solution, which provides lowest per unit cost as the backhaul traffic increases
• CFN takes away the hassle and worry of managing an Outside Plant Network such as relocations, construction, outages, etc. by managing the full solution so as a customer you get only the benefit of dim without the down side.
• For longer spans, CFN can provide mid-span regeneration reducing equipment, new collocations and operational cost and complexity for the customer.

Webinar: Trading Beyond the Horizon

Trading Beyond the Horizon: Fragmentation Drives Multi-Market Execution Join us for a Webinar on June 30 Learn how to optimize your trading architecture for low latency Space is limited. Reserve your Webinar seat now at: www.a-teamgroup.com/webinar/trading-beyond-the-horizon/ In 2010, financial markets participants will continue to expand their trading activities as liquidity increasingly becomes fragmented, seeking alpha in new markets, best execution in dark pools, arbitrage opportunities across the order book and by implementing high frequency and complex, multi-leg, cross asset class strategies. The successful trading operations will leverage an infrastructure that leverages high-speed long haul and metro communications along with optimized use of proximity and co-location sites to access multiple, geographically dispersed execution venues with the lowest latency. Participants are looking to implement flexible networking architectures to keep pace with market developments, while at the same time they need to retain management control of this strategic capability in order to continually optimize their proprietary trading and customer brokerage businesses. Join us for a webinar where you will hear from, and have a chance to ask questions of, a panel of industry experts who will address the issues of implementing an optimized trading architecture.

For many years, the only “free” market data was delayed data, released usually after 15 minutes, to provide an indication of the market for non-professionals, while traders would still need to subscribe to expensive real-time prices. More recently, new ECNs and MTFs have begun offering data free of charge to attract trading volumes. And now, these venues are having to balance staying true to their roots with the benefits of-or business need for-market data fees, which contribute significant revenues to the bottom lines of their established exchange rivals.

Low latency connectivity has enjoyed a resurgence of interest as high-performance trading architectures become a reality. Early interest in the low-latency ‘vision’ may have been interrupted by the global financial crisis, but no matter: low latency is back, and providing the catalyst for the explosion in high frequency trading.

As liquidity continues to fragment – in the US and globally – electronic trading operations are demanding connectivity to a broader array of execution venues. As well as traditional exchanges, traders today need access to alternative trading systems, including electronic communications networks, dark pools and multilateral trading facilities (MTFs). Securing and maintaining a robust, high-performance connectivity solution is key to providing comprehensive market access Download Now
