Assurance visualization can prepare network operations tools to meet the demands of increasingly complex networks. And the limitations of today’s tools are indeed a cause for concern.
- Will they be efficient enough to meet new network operations requirements?
- Will they scale to meet the challenges of tomorrow’s network operations environment?
As networks evolve to next-generation IP/optical technologies, cloud networking, software defined networking (SDN), and network functions virtualization (NFV), network operations tools need to evolve, too.

A Wi-Fi first strategy can help multi-system operators (MSOs) remain competitive in the evolving marketplace. Wi-Fi enabled devices default to using the cable operator’s Wi-Fi network for voice, and cellular equipped devices can switch to cellular when out of Wi-Fi range.
Although nuances in the business drivers for adopting such a strategy vary by region globally, this model turns the traditional cellular voice paradigm on its head.
Just like other communications or media industries, MSOs face a dynamic and extremely competitive market. As a result, in EMEA, they have evolved their end-user offerings to embrace market-leading fixed high speed internet access, Wi-Fi connectivity, and bundled mobile cellular services using mobile virtual network operator (MVNO) partnerships.
As the pace of change continues to accelerate, subscribers have made a widespread move to Wi-Fi enabled smartphones and tablets. A European commission study stated that 71% of all EU wireless data traffic in 2012 was delivered to smartphones and tablets using Wi-Fi. This is expected to rise to 78% by 2016.
European MSOs have already invested in Wi-Fi and offer data connectivity services in and out of the home. This not only is a customer retention strategy, but also lets MSOs build out further value added services (VAS) and can reduce data costs of their MVNO agreements. So if we now contemplate the delivery of voice to these Wi-Fi enabled devices, how do we get started?

IP/optical integration typically results in cost savings, but maintaining service availability is also essential when measuring total return on investment (ROI). An analysis of 3 modes of operation found multi-layer protection and restoration to be the most cost efficient while meeting availability requirements.
OpenStack isn’t an as-is solution for telco network functions virtualization (NFV) infrastructures. OpenStack is an open-source cloud management technology that provides many of the capabilities needed in any NFV environment. And this has prompted interest among many telco service providers.
But to realize the full benefits of NFV, service providers need NFV platforms that provide additional capabilities to support distributed clouds, enhanced network control, lifecycle management, and high performance data planes.

This article provides guidance on network architecture choices for operators considering introducing the time-shifted TV services provided by cloud digital video recording (DVR) solutions. Time-shifted TV services include catch up, restart, pause live TV, and personal recordings. The same guidance applies to those wanting to deliver subscription-based VoD services—either their own or those of partners.
Forward thinking providers are already concerned that the coming wave of unicast traffic generated by popular on-demand video services will affect the delivery network from end to end. Clarifying the potential impact of these services on the network is vital as the ramifications could be significant.
For what seems like ages now the communications industry has been talking about convergence. We have already gone through many phases as networks move from TDM to being end-to-end Internet Protocol (IP) with voice traffic increasingly being carried on converged networks. Indeed, the popularity of Voice-over-IP (VoIP) and the coming of Voice-over-LTE (VoLTE) on mobile networks is the future.
That said, convergence is not just about IP but is also about the transformation of global network infrastructures in the wired world, with legs into the wireless one as well, of IP and Optics. And, as Steve Vogelsang, VP Strategy and CTO, IP Routing and Transport Business Division, Alcatel-Lucent noted in a recent TechZine blog, IP and optics: Time to make nice, “Let’s face it. The future of the communications industry requires a convergence of IP and optics. So maybe it’s time to give each other some overdue respect."

The move toward 4G LTE is a seismic shift in mobile architecture inasmuch as it finally takes operators to an all-IP architecture. No more packet/TDM mix that adds complexity and slows down the network.
The rise in LTE also has meant a explosion in demand for packet core technology. Packet core revenue grew by 20 percent in the second quarter of this year compared with last year, for instance, according to research firm Dell’Oro.
The evolved packet core (EPC), as the LTE packet core is known, is both the brains and the brawn of LTE. Data goes from handsets across the backhaul network to the EPC, where the data is processed and then forwarded onto the Internet or another public or private network from the mobile provider.

Compensating for the ever-increasing demand for high-bandwidth connectivity is every service provider's number one concern. This is for good reason. Next generation services can help mobile operators limit churn and enable them to tap into new revenue streams and improve their bottom lines.
Unfortunately, completely rebuilding a network is cost-prohibitive for most service providers. This creates a quandary over what to do. One viable option for forward-thinking service providers is IP/MPLS backhaul solutions. These enable carriers to leverage their existing broadband access infrastructure – whether it be microwave, copper (DSL) or fiber-based (GPON). In the process they serve as the foundation for a flexible high-performance network, all without major capital expenditures or increased operating expenses.
Several broadband access solutions currently exist, but most all of them fail to successfully address broadband infrastructure backhaul requirements while leveraging DSL or GPON.

“Your surveillance network should dictate your power and equipment requirements, not the other way around. Often operators tell me they want 50 cameras. I ask them what they think every one of those cameras should be doing. It’s very easy to over-engineer systems and overwhelm your ICT network with unnecessary data.”
In addressing network operators in a recent article in Alcatel-Lucent’s Tracktalk, Making the case for Enhanced Rail Security Systems, the above expert advice was provided by Dave Gorshkov, CEO of Digital Grape Business Services.
“Security is essential to the modern railway, protecting passengers, staff the operator’s assets from diverse range of risks including terrorism, crime, trespass, and vandalism,” he continued, noting that few security systems are installed without the support of a robust business case.
