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.
