100G and IP + Optical Convergence Key Themes at Cisco Packet Optical Conference

Customers from around the world are gathered today at Cisco’s campus in Richardson, Texas to kick off the Spring 2012 Packet Optical Networking Conference (PONC). This brings together network operators, large enterprise customers, optical industry leaders, and Cisco solution teams at a three-day event to collaborate on best practices and future requirements in IP and optical solutions. Some of the key themes that will be featured at this year’s event include:

  1. 40G/100G Coherent DWDM transport over 10G infrastructure: Much of the infrastructure today was designed to support only 10G wavelengths.  It is undesirable to cap and start over with new infrastructure that is purpose built for 40/100G.  Cisco’s unique Coherent optical transport technology is a game Read More »

Integrating Wi-Fi into Today’s Mobile Networks

By Peter Gaspar, Consulting Systems Engineer, Service Provider Mobility, Emerging Theater

It’s not new news that when it comes to network access, Wi-Fi technology is a cost-effective complement to macro radio access. Industry blogs continuously feature analysis about the economic advantages of using Wi-Fi as a small cell technology. No surprise, then, that many mobile operators have completed or are working seriously on plans to integrate this technology into their mobile ecosystems.

But when it comes to details, things start to get confusing. Terms like policy and charging, lawful intercept, mobility and SIM authentication start to pop up. The Third Generation Partnership Project (3GPP) has incorporated Wi-Fi (non-3GPP IP Access) as part of the LTE architecture, created the terminology and studied the Read More »

Carrier Cloud Forum (CCF) at Interop 2012

Lately, our customers have been expressing interest in a number of cloud topics:

  • What are best practices in building a cloud business?
  • Enterprise-grade solutions versus best-efforts applications
  • Standardization and security
  • Connectivity from end-to-end
  • Advanced technologies within and between clouds

I’m looking forward to continuing the conversations with cloud service providers next week down in Las Vegas. If you’re coming to Interop, we’re continuing Read More »

A Rainy Day in London Town

By Lisa Garza

It was raining in London last week during the LightReading event Strategic Opportunities in Service Provider Wi-Fi.  That might not sound unusual, but actually my cab driver said it had been a dry winter, and the rain was much needed for his garden.  That’s how I felt about the event – it felt like a lovely spring rain.

Heavy Reading Senior Analyst Gabriel Brown first addressed the packed room by likening the early days of Wi-Fi to the Wild West.  With the advent of carrier-grade Wi-Fi, the integration of Wi-Fi into Mobile networks, and initiatives such as the Wireless Broadband Alliance Next Generation Hotspot Program, the west is slowly Read More »

The Cisco – SP Partnership: How Proactive Planning Drives Service Quality

By Carlos Cordero, Director, Service Provider Internet Business Solutions Group

In my previous blog I explained the importance of collaborative testing between telecommunications service providers (SPs) and their network vendors in order to achieve higher service quality levels. I’d like to start where I left off and move on to exploring how this type of collaboration can extend into the planning process.

SPs with the highest service quality tend to have a strong planning capability within both their Network Engineering and Operations organizations, which is directly coordinated with their vendors. Leading SPs establish a joint Program Management Office (PMO) with their network equipment vendor, whose scope of responsibility includes early bug identification, bug remediation, and new feature deployment. This includes structured, joint planning meetings and performance reviews which are attended by VP-level engineering and operations executives, as well as senior members of the vendor’s account team, services organization, and the development organization.

The joint SP-vendor PMO performs several critical activities.  First, it drives requirements gathering with senior network designers, and then works with them until actual code is released.  The PMO also develops network architectures with the vendor and the SP’s engineers using “Plan-of-Record” (POR) documentation.  Next, the PMO jointly prioritizes feature functionality with the vendor, keeping track of critical features needed by specified timeframes.  It works closely with the vendor’s development organization to understand any design limitations, testing issues, and special conditions.  In addition to performing classic management functions, the PMO makes use of “Bug Workbooks” to track all major, critical, and minor bugs and trends.

For example, Read More »
