Cisco adds SDN expertise with purchase of startup Embrane

Cisco plans to acquire Embrane, a software-defined networking startup that already has an established relationship with the manufacturer. Terms of the deal were not released.

Cisco, Alcatel-Lucent, Huawei, Juniper maintain carrier router/switch lead, but SDN causes carrier pause

Software defined networking (SDN) may be the talk of the town, but as providers try to figure out how to use it in their networks, it could dampen near-term opportunities for the largest router/switching vendors, says Infonetics Research.

SDN-driven backhaul could save carriers $9B by 2017, says study

Software-defined networking (SDN) could save operators $9 billion in mobile backhaul-related operating expenses by 2017 as they gain the ability to dynamically manage traffic and backhaul bandwidth, according to fresh research.

Cisco sharpens SDN focus with $683M Insieme purchase

Cisco has acquired the remaining stake of Insieme, a so-called spin-in company they created last year for an estimated $683 million as a way to establish a foothold in the emerging software defined networking segment.

TIA 2013 Scorecard: Managing SDN, the cloud, and the end of the PSTN

TIA 2013 may be an offshoot of the Supercomm event, but this show is nothing like its predecessor. FierceTelecom chronicles the top trends that dominated discussion.

SDN-based backhaul applications will save $4B in capex, report says

Software-defined networking could save mobile operators more than $4 billion in capital expenses in 2017, with the largest capex savings stemming from metro aggregation/load, according to fresh research from Strategy Analytics.

Jarich: SDN- a rose by any other name… still wouldn't be NFV

We've talked about Software Defined Networking (SDN) and Network Functions Virtualization (NFV) multiple times this year. While still relatively new concepts, there's general consensus that both have the potential to revolutionize the way in which we think about mobile networks and services: SDN thanks to driving service velocity and manageability, and NFV thanks to rethinking the platforms on which networks are built and how network capacity is (cost-effectively) turned up or torn down. To be sure, there are still plenty of questions around them.

Week in research: VDSL2, vectoring drive new DSL deployments; Telcos outline SDN, NFV plans

Fiber to the Home (FTTH) may offer the fastest broadband speeds, but a recent  broadbandtrends.com  report says that in the near-term, most traditional telcos are opting to use a hybrid copper/fiber approach that uses a mix of VDSL2 and vectoring technologies.

Transport SDN: A new flavor for software defined networking

As data center providers look for ways to reduce capital expenditures, such as data center interconnect and multi-layer optimization, a new opportunity has emerged for software defined networking: transport SDN. However, transport networks face significantly different challenges than packet networks.

ConteXtream's whodunit: Which Tier 1 carrier launched massive SDN deployment?

ConteXtream announced that a Tier 1 U.S. wireless operator has deployed the vendor's software-defined networking (SDN) technology to virtualize almost half of its network. The Palo Alto, Calif., startup is not specifying which carrier adopted its product but said the company is using SDN to serve nearly 40 million customers.
