Building a simple, smart, scalable foundation for Software-Defined LANs

What if you could dynamically allocate LAN bandwidth based on real-time needs in software? What if you could pre-program strict quality of service (QoS) to different LAN users, services, devices and ports? What if you could manage secure authorization and authentication in software and automatically associate to users, services, devices and ports?

If you could, then you would have the foundation for a software-defined “LAN.”

You’ve guessed it, that’s exactly what Optical LAN delivers....

Why small cells are poised for growth in Latin America

Small cells mean big changes for mobile networks

Already an important element in 3G networks globally, small cells enable network coverage to be easily extended to accommodate data growth, especially in busy outdoor areas. However, as operators move to 4G/LTE networks and introduce heterogeneous networks (HetNets), small cells become even more important. Why?  Because LTE technology promises higher bandwidth in the radio interface, end-users also expect better service, lower latency and more throughput. This...

How secure is your LAN?

Do you know who can intercept the communications going through your local area network (LAN)? 

Interception is easier than you might guess, because most LANs use copper wiring. Copper acts like an antenna -- broadcasting radio frequencies that can be intercepted even without a physical tap.

How do you combat copper’s security weakness within a high-security network? If you stick with copper, your protected distribution systems requirements include:

  • Installing copper cable outside floors, ceilings and wall for constant visual inspection
  • Encasing copper cabling in...

Creating standards for higher-speed networks of tomorrow

The networks of tomorrow will need higher speeds than networks of the past. 

That’s because new applications are increasing bandwidth needs in fiber optic networks.  In addition, cloud computing leads to greater variability in traffic destinations. Customers need new technologies to support communications and dynamic network reconfiguration at higher speeds.

For DWDM (dense wave division multiplexing) transport technologies, the Optical Internetworking Forum (OIF) is the leading industry...

The future of energy efficient telecom technology is here

Sometimes the future arrives sooner rather than later. Take energy-efficient access technology, for instance. Its future actually arrived a few years ago, in the form of the Tellabs Optical LAN

Back in 2008, the U.S. Department of Energy (DOE) brought together more than 60 experts from the energy, telecommunications and IT industries. DOE wanted them to brainstorm ways to boost the energy efficiency of, among other things, data centers and telecommunications...

Stay safe with reliable public safety networks

The U.S. government is funding a program to improve public safety. It’s called FirstNet, which has $7B currently available to build a nationwide, public safety network using LTE.

The idea is to create a nation-wide broadband network, which helps police, firefighters, emergency medical service professionals and other public safety officials to do their job safely. In additional to federal funds, the state and local governments are contributing to this initiative. And private companies like Agile Network...

Why service providers want OTN in metro networks

My conversations with service providers lead me to believe that OTN switching technology will begin increasing in metro network deployments, in order to further transport efficiency. In fact, we’re testing our new OTN upgrade for the Tellabs 7100 series in customer labs today.

Two key trends are paving the ways for OTN switching in metro networks:

  • Wireline, wireless, video, and data center traffic is growing in metro networks.
  • Enterprise are adopting gigabit services and beyond. 
  • To virtually...

    What is the best migration path to LTE?

    Racing to LTE is well under way with over 145 commercial LTE networks launched on a global basis according to GSA. Yet, a lot of operators are still evaluating what is the right migration path to enable single, converged mobile backhaul infrastructure to carry voice, data and video for 2G, 3G and LTE. Naturally, the cost per bit needs to remain as low as possible and the new infrastructure needs to be scalable and flexible. 

    I’d advice operators to modernize the network to IP/MPLS. It provides flexibility...

    Why fiber outperforms copper in telco networks and LANs

    Ask a telecom service provider’s CTO, “Would you prefer to operate network infrastructure based on fiber optics or a copper-based network?” These CTOs snap back in a second, “Fiber!”

    Now ask a CIO or IT manager, “Would you prefer a local area network (LAN) based on fiber optics or copper?” and you may hear 100 questions.

    How did telecom network operators reach the conclusion that fiber is better? It’s smaller, lighter, stronger, higher bandwidth, longer reach...

    Optical LAN vs. copper-based LAN: Which performs better?

    Network users need more and more bandwidth. At the same time, your CFO wants to reduce IT spending. How can you address both needs with your local area network (LAN)?

    With Tellabs Optical LAN, you can gain bandwidth and lower costs at the same time. Optical LAN offers these advantages for enterprises and government agencies:

    • Seamless migration to IP. It’s easy to migrate from plain old telephone service (POTS) to VoIP (voice over Internet protocol), and from RF (radio frequency) video to IP video.
    • Higher throughput. We deliver up to 1G to the...

    MWC 2013: Network intelligence drives successful SDN deployments

    Anyone who attended Mobile World Congress (MWC)’13 will tell you one acronym ruled the event: SDN. ACG Research’s Ray Mota tweeted he was sure he’d find an SDN lunch special on the menu as his SDN-mentions counter neared 300.

    Tellabs Insight Analytics is my main focus, so I was especially interested in what mobile operators had to say about network intelligence and how it relates to SDN.

    Before SDN can be implemented properly, it’s critically important that...

    Mobile operators risk backhaul gap in LTE networks

    Mobile operators are adopting LTE at rates even faster than 2G and 3G. As operators race to stay ahead of mobile data demand, LTE is one key to the future.

    Tellabs commissioned a new study by industry analyst Strategy Analytics on LTE mobile backhaul. The findings were surprising – and alarming.

    If operators continue to invest in mobile backhaul for LTE at the same rates as they did for 2G and 3G – about 17.5% of the total cost of ownership – they risk falling short...

    Mobile cloud services sustain revenue and growth in new LTE networks

    By Stuart Benington, Director of Portfolio Strategy

    As mobile operators invest heavily to migrate to LTE networks, they face a major financial challenge in the near-term. The number of LTE-based services — and the profits they bring in — will require a long-term horizon to achieve a return on investment (ROI).

    To speed up their ROI, operators can support an LTE business model with revenues from other services using the same technologies and...

    Building a future-proof IP/Ethernet-based RAN

    Friends, family members and even total strangers communicate with each other with an ever-increasing variety of social media and VoIP services. People exchange music, photos and YouTube videos that they want to stream quickly and easily over networks with smartphones, tablets or other mobile devices.

    These popular new methods of communicating present new challenges for service providers...
