Smarter Networks: Nuage Networks & SD-WAN (Part 2)

This is a two-part post – Part 1 introduces challenges of traditional WAN’s and Part 2 (this post) describes Nuage Networks SD-WAN solution.

Nuage Networks SD-WAN

Traditional WAN’s hinder business operation and don’t meet the demands of today’s applications. A new emerging WAN architecture called SD-WAN replaces existing WAN’s with a business aware approach to networking. This approach is now thoroughly adopted by Nuage Networks and their SD-WAN solution is solving the limitati [...]

Smarter Networks: Nuage Networks & SD-WAN (Part I)

This is a two-part post – Part 1 (this post) introduces the challenges of traditional WAN’s and Part 2 describes Nuage Networks SD-WAN solution.

It’s a 24/7 connected world and traffic diversity is putting the Wide Area Network (WAN) edge to the test. Today’s applications should not be hindered by underlying network issues or a poorly designed WAN. The business requires designers to find a better way to manage the WAN by adding intelligence with improved flow management, visibility, a [...]

Nuage Networks Professional Services + Red Hat Consulting: Your ‘must-have’ navigation tool for IT transformation to SDN-enabled hybrid cloud solutions

Guest blog by Chadie Ghadie, Director, Professional Services PLM, Nuage Networks and Tom Anderson, Director, North American Cloud Practice, Red Hat

Having spoken to many customers in the last year, a common message we hear is that enterprise IT is becoming increasingly complicated with multiple inter-working systems. This is the nature of how these systems were built over multiple years, or cobbled together following mergers or acquisitions.

With the shift to cloud, these IT systems have b [...]

Want to lead in the fiercely competitive financial services market? Invest in open, hybrid clouds with SDN

Guest blog by Johnray Fuller, Solutions Architect, Red Hat and Senad Palislamovic, Director, Systems Engineering, Nuage Networks

Perhaps no vertical illustrates volatility and global competitiveness better than the financial services industry. The global recession has taken its toll; slow growth, customer distrust and a more aggressive regulatory environment. Financial services companies need modern technologies that foster dynamic business operations—technologies like open, hybrid clouds w [...]

What’s A SDN Platform, Really?

Blurred Lines

I’ve managed, marketed, and implemented quite a few application and infrastructure offerings in the course of my career. This varied set of experiences has taught me that the line between a robust product and a true platform can be fuzzy.

For example, it’s frequently difficult to tell if a given offering is a product dressed as a platform or a platform that’s dressed as a product. Similarly, it’s hard to figure out if an offering is a true Software Defined Networking [...]

“Libnetwork” is License to Hyper Scale for Docker and SDN

Virtualization brought significant changes in networking by moving the edge of the network in the server itself. This led to a significant increase of network endpoints and new requirements for the network in terms of provisioning for both speed and flexibility. To a certain extent the ideas of virtualization and cloud gave birth to the whole notion of software defined networking (SDN) since the network needed to keep up with the deployment speeds of virtual machines (VMs).

Docker and microse [...]

Hello World: Introducing OpenStack DevOps Cloud Reference Architecture

Nuage Networks first shipped Virtualized Services Platform (VSP) in 2013.  Since then, VSP has been operational in some of the largest data centers around the world, making the cloud “real” by making the network as accessible and fungible as the compute side of the house.

OpenStack powers the cloud orchestration layer in most of our installations.  And, to meet our customers’ networking needs, we have been busy building a partner ecosystem.  Among other functionality, we have deploy [...]

It’s Overlay O’clock ! Do You Know Where Your Packets Are?

Some time ago, we discussed the principles of overlay networks and the design requirements for the physical infrastructure that can support such networks. As discussed in this blog, almost every communication channel we have today is indeed using one or more overlays - IP over Ethernet, IP over Optics, Wireless access over GRE tunnels over IP over Optics etc.

The idea of decoupling services from core networks, maintaining a simple core and pushing intelligence at the edge has been fundamental [...]

The SDN mindshift

Software Defined Networking (SDN), the big buzz of the moment in enterprise networking, is defined as creating a layer of abstraction, providing greater management flexibility and lower operational costs.

Traditional enterprise network environments that resist change further exacerbate the problem of operational complexity, which is a key challenge, as the data centre becomes increasingly complex. According to IDC, this is the key reason that enterprises are so keen to leverage the capabil [...]

What’s up with the datacentre network?

We are in the midst of a transition in IT. Over the last couple of years the cloud has morphed from a disruptive technology on the periphery of IT into the mainstream.

Business competitive advantage these days is dictated by swiftness and agility, increasingly around business-driven applications that attain this advantage in the marketplace. This new edge is being pushed hard by enterprises that are adopting web-scale capabilities through software, drawing them into their inherent business pr [...]
