Case Studies

Case Study: Full-managed Trading Infrastructure

As lead traders in large corporate investment firms and banks begin look for more control over their future, many are taking the leap to start their own proprietary trading firms. One such high frequency trading firm came to CFN Services with a challenge. Their goal was to be up and trading real-time within 30 days. They had worked with other vendors to integrate a comprehensive solution that would optimize the trading ecosystem from pre- to post-trade execution. As they struggled with contracts and vendors, they requested for CFN to assist in the effort so they could focus on the goals and profitability of their multi-asset trading strategy.

Case Study: Global Content Managment

Background: Global Content Network Background A leading content provider wanted to create a global content network. The provider wanted this network to be tested in 32 sites that were found in North America, South America, Europe and Asia to help with the economic costs of the services that would be needed to create this network. The provider wanted to know the economics of using SONET, wavelength or dark fiber services for this project.

Case Study: Wireless Backhaul Optimization

Background: A Tier 1 mobile carrier was operating a statewide network of more than 1,000 cell sites interconnecting with 2 primary mobile switching centers (MSCs). The carrier was spending more than $15 million annually on local access transport services for backhaul from the cell sites to the MSCs and interconnection from the MSCs to the local telephone company’s (LEC) access tandems. Planned 3G network upgrades promised to double T1 capacity requirements at more than 600 cell sites.

Business Challenge: Reduce leased network transport costs in the face of planned capacity growth, while positioning the backhaul network to support 3G broadband data services.

Case Study: Fiber Characteristics

Fiber-optic communication is a method of transmitting information from one place to another by sending pulses of light through an optical fiber. This is important to note when discussing the variables that affect latency.

Distance: The definition of zero network latency would be network transport at the speed of light. That said, the further the light has to travel the higher latency. Obtaining just a fiber connection from point A to point Z is no longer sufficient to ensure optimal data transfer speeds. Fiber networks do not normally follow a direct line between any given "A" and "Z" location. It follows geographic contours relating to roads, railroad tracks, or other types of right-of-way where the fiber was placed. For this reason it is important to understand the exact route your circuit follows. You want to eliminate any wasted distance. For dark fiber as well as lit circuits, that is not an option for a typical service provider, as they are quoting their circuits on an existing fiber path that in most cases cannot be varied. However, a network integrator that can utilize optimal spans from multiple providers will be able to piece together the most direct route, incorporating new fiber construction where required.

Case Study: Local Access Transport Optimization

Background: A leading global carrier with more than $30 billion in revenues had launched a strategic initiative to significantly reduce the $10 billion in local access transport costs it was spending with the local telephone companies (LECs).

Business Challenge: Look at feasibility for local access network optimization and LEC collocation expansion in markets with a strong existing fiber footprint, a limited existing fiber footprint, and no existing fiber footprint. Build a business case for network expansion across all market types with limited capital deployment and no required operational resource expansion.

Case Study: Local Access Network Expansion and LEC Collocation

Background: A leading global carrier with more than $25 billion in revenues had launched a strategic initiative to significantly reduce the $8 billion in local access transport costs it was spending with the local telephone companies (LECs).

Business Challenge: Expand the base of LEC collocations in several high cost Tier 2 markets on a limited capital budget with limited operational resources.
