Broadcom and Freescale Semiconductor have announced switching platforms that promise to improve the performance of network virtualization and make the underlying technologies more widely available.
The focus in SDNs and programmable networking is shifting to application policy, an area where vendors can instill their unique architectures and maintain customer dependency.
Making the leap to SDN? Don't jump in blind. It helps to know what software-defined networking is, first off, and then what it can do for you.
Cisco Systems released new firmware versions for some of its small business routers and wireless LAN controllers in order to address vulnerabilities that could allow remote attackers to compromise the vulnerable devices or affect their availability.
NEC this week rolled out a new version of its SDN software that includes an OpenFlow-based method for interconnecting data centers.
OpenDaylight, the vendor-heavy consortium developing an open source SDN framework, has announced that its first software release is available for download.
Next year will see demonstrable evidence of the Internet of Things, real-time communications on the Web, and SDN-enabled platforms with killer applications for them.
Cisco's introduction of the Insieme Networks product line and strategy was the most anticipated networking announcement in almost two years. It represents Cisco's response to the software-defined networking trend pervading the industry, and threatening Cisco's dominance and profits. While not a watershed moment – Insieme didn't change Cisco's modus operandii, as explained below -- Insieme is nonetheless one of the most important events and product introductions in Cisco's history. Here are 10 things we learned or have yet to learn from the Insieme launch:
Juniper Networks this week unveiled a new top-of-rack data center access switch, as well as a new fabric architecture that features that switch along with the company's MX edge router and SRX security platforms.
Upgrading you network from 10G Ethernet to 40G and 100G is not as easy as swapping out switches and line cards.
Cisco Systems has released security patches for authentication bypass, command execution and denial-of-service vulnerabilities affecting products that use its Adaptive Security Appliance (ASA) software, as well as the Cisco Catalyst 6500 series switches and Cisco 7600 series routers.
Ethernet's value to networking and IT is well established over the past 40 years. But did you know that "Ethernet" refers to two slightly different ways of sending information between endpoints on a LAN? That and some other perhaps lesser known facts about this 40-year-old technology are reviewed here:
Internet traffic will quadruple in five years and the number of mobile Internet connections will exceed the world's population by 2017, according to Cisco research.
While much of the hype for software-defined networking is focused on large-scale data center deployments, some companies are taking a different angle.
Hewlett-Packard will allow enterprises to pay for managed LAN offerings based on usage, in much the same way they pay for cloud services, through a partnership with telecom service providers.
