SDN security strategies for network attack prevention

Software-defined networking (SDN) technology pulls a network’s control plane into a dedicated SDN controller, which manages and mediates all functions and services on virtual and physical networks. Because of this separation and control, SDN security strategies offer a deeper level of granularity to packet analysis, network monitoring and traffic control that will go a long way in ...

Why should I care about software-defined networking?

Why should I care about software-defined networking, or SDN? “Software defined” has become the label du jour in networking, attached to nearly everything in the data center– including the data center itself. The fundamental idea behind the approach is that there is a separation between the decision making (or “control”) function of the device or ...

Application awareness in cloud networking: Real or imagined?

Even before the cloud came along, there was considerable interest in the idea that networks should treat every application differently because each has unique needs — a concept known as application awareness or application-aware networking. With its potential to host applications on the network, the cloud is especially sensitive to application performance issues caused by ...

Meet Facebook’s new network architecture: it’s a fabric

This was posted originally on Gigaom. SUMMARY:Facebook experiences 1,000 times more traffic inside its data centers than it sends to and receives from outside users. That traffic growth has prompted the social network to design a fabric networking architecture. Facebook, in its quest to serve its more than 1 billion users, has redesigned its network ...

Software is important to networking, and Juniper is on it

SUMMARY:As more data centers become virtualized, networks aren’t keeping up with compute and storage, preventing easy scalability. Juniper wants to help solve the problem with software, while keeping its hardware relevant. As software-defined networking (SDN) startups such as Big Switch and Embrane make headway and headlines, Juniper and other big network gear vendors have been ...

Juniper: simplifying datacentre opps

Automating network management. Juniper Networks updated its EX and QFX Series switches, along with its Junos operating system, to include new capabilities for simplifying data center operations and automating network management. Among these updates, Juniper said, is the integration of Puppet Labs’ automation software into its own Junos OS, an enhancement Juniper said will allow ...

New core router to boost revenue: Cisco

Can handle 10x data. Cisco predicts that a new product it unveiled on Wednesday will increase its cumulative revenue from core routers, which direct Internet data traffic, by 25 percent – to $US10 billion – within the next two years. The leading network equipment maker expects to cash in on ever increasing demand for Internet ...

University quick to deploy software defined networking

This was posted originally on TheAge. UTS is taking the lead on software defined networking. Photo: Quentin Jones The University of Technology Sydney has revealed it is one of the first large organisations in Australia to deploy a software defined communications network (SDN). SDN technology moves the management and configuration of network routers out of the hardware ...

Heck yeah! Facebook’s Open Compute Project is making an open source switch

  photo: Stacey Higginbotham SUMMARY:Not content with open sourcing the server and storage hardware inside data centers, Facebook’s Open Compute Project has teamed up with others to build an open source top of rack switch. Here’s why it matters. The Open Compute Project, which Facebook launched a little more than two years ago, has decided ...

Smaller equals scale for Riverbed’s new mini application-delivery software

SUMMARY:To bring scalability to application delivery controllers, Riverbed has miniaturized its software, so load-balancing resources can keep up with changes in storage and compute. The computing services available through Amazon Web Services and Windows Azure enable customers to pay for as much compute and storage resources as they use. But what about functions like load ...
