Chipmaker Intel has launched three “strategic reference architectures” that the firm claims will enable IT and telecom firms to accelerate hardware and software development for software-defined networking (SDN) and network function virtualisation (NFV).
With virtualisation evolving rapidly and open source in favour, telecom equipment vendors could all end up developing what is effectively the same software to manage the cloud. But what they have to bring to the table is telecom-grade experience.
Japanese vendor NEC has established a partnership with Portuguese incumbent operator Portugal Telecom that will see the two firms collaborate on SDN (software defined networking) and virtualisation technology for datacenters and carrier networks.
Chinese equipment vendor Huawei clearly envisions a world where network applications and services will run on commodity hardware and software. For a company that sells specialist boxes into networks, this could be a bold statement. In the latest in our series of SDN-themed interviews, Sanqi Li, CTO of Huawei’s carrier network business, simply sees this approach as the evolution of business models for both carriers and vendors.
With Software Defined Networking (SDN) generating a lot of interest at MWC, there are plenty of approaches jockeying for position. Networking equipment vendor Juniper Networks recently came out with its own contribution and a four-step approach to implementing the concept.
In the first of our series of features on Software Defined Networking, Marcus Weldon, CTO at Alcatel Lucent and Bell Labs, gives Telecoms.com his take on the buzzword of the moment.
Software Defined Networks (SDN) for telecom networks are the next big thing and MWC was not short of announcements and new marketing campaigns from big vendors. It comes at the right time too, when LTE and data awareness now require greater network flexibility, scalability and cost performance. The difference with earlier technologies is that IT vendors are now entering the telecoms market since SDN (or virtualization) is a concept widely used in the IT market.
Of late there seems to be an SDN (software defined networks) related announcement every few days, as vendors get their ducks in a row to pitch the next evolution of technology to carriers at MWC. But the concept demands a change in mindset for the vendors as much as it does the operators.
Software-defined networking (SDN) is the latest acronym to save the day, promising more flexible, scalable and intelligent networks. But what does SDN actually mean?
It feels like 2006 once again: vendors are creating fanciful and colourful presentations about SDN and operators are discussing about the need to move from silos to horizontal platforms and networks. In a way, almost the same story was told six years ago for IMS, but deployments were far smaller than expected. So is SDN following the footsteps of IMS?
Standards body and industry specification group ETSI is to develop an architecture for the virtualisation of various functions within telecoms networks.
With traditional network architectures struggling to cope with more dynamic applications and services, software-defined networking (SDN) provides the answer to operators’ woes, according to research firm Ovum. The company believes SDN will be key in enabling future networks to become more flexible, scalable and intelligent.
