Alcatel-Lucent uses SDN to meld IP, optical services

Alcatel-Lucent this week extended its carrier SDN product line with an automation and network control system designed to accelerate service provisioning from multivendor IP and optical infrastructure.The company’s Network Services Platform combines Alcatel-Lucent’s SDN-based software with its 5260 service-aware management system, Service Router operating system and the 1830 Photonic Service Switch GMPLS routing engine algorithms from Bell Labs. It also has a REST API interface to the Nuage Networks Virtual Services Platform SDN controller for data center networks so the IP/MPLS/optical network can be quickly provisioned based on the needs of data center interconnection and virtual machine mobility.To read this article in full or to leave a comment, please click here

Open source meets telecom at NFV World Congress

When Linux first became a serious challenger for enterprise-class infrastructure, traditional IT vendors had to contend and to rationalize just what exactly this open source thing was. The initial response from many vendors was to attempt to stop it, but it only grew. And as open source grew, many mostly younger businesses learned to leverage it for great commercial success; however, the titans of the previous era have had challenges adapting their business models to embrace open source successfully.To read this article in full or to leave a comment, please click here

VeloCloud’s SD-WAN puts packet steering on steroids to optimize performance

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.  Many vendors are racing to compete in the burgeoning software-defined WAN space. Each competitor has its own strategy of how to implement the network overlay that makes the network connections, provides virtualized services and steers applications. It all comes down to what the SD-WAN vendor wants to help its customers achieve.VeloCloud has an entry in this race, and the company has two goals: to simplify the way companies set up their branches within their wide area network, and to improve the performance of the WAN. There are several specific problem areas VeloCloud is setting out to address.To read this article in full or to leave a comment, please click here

Digging Deeper into the Cisco ASA Firewall REST API

Security orchestration methods and of course SDN is driving the need for programmable interfaces in  security products.  The Cisco ASA Firewall added a REST API back in December with the 9.3(2) code release.  I've asked Mason Harris, from Cisco, to write up a quick how-to primer on the ASA API capabilities.  Thank you Mason for the great information.Author: Mason Harris CCIE #5916Solutions Architect, Global EnterpriseOver the years I’ve seen many different custom methods used to manage ASA firewalls. Most of them involve some version of command line interface (CLI) scripting since nearly all ASA features and functions are available in this manner. Perl and Expect scripts are the common scripting languages in use today for managing ASAs.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Yes, Virginia, NFV services can be testable, scalable and predictable

One of the coolest demonstrations at the RSA Conference in San Francisco was of a network functions virtualization (NFV)-based firewall and Deep Content Inspection engine embedded into the software-defined networking (SDN) control plane of a heavily laden network. The firewall/DCI engine filtered content and blocked SQL injection attacks in real time, without slowing down the simulated network. The OpenStack-based testbed was created and run by Spirent, a Southern California firm well known for its network testing platform. The security firm with the firewall and DCI engine was Wedge Networks, a Canadian company that's focused on the cloud.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Winds of change blowing in the WAN

In the past few years, enterprise computing has experienced major upheavals brought about by cloud apps, Wi-Fi, mobility, and BYOD. The enterprise WAN, meanwhile, has not evolved much since it was transformed into an MPLS Layer 3 VPN infrastructure more than a decade ago. Things are about change. Based on my experience with customer deployments, more than 50% of enterprise traffic from branches is currently Internet-bound. This is due to outsourcing of utility applications, including email, search, voice, video and collaboration, not to mention cloud application use. Despite this trend, enterprises have resisted using the public Internet to provide remote offices with direct access to cloud applications. This is primarily due to compliance issues, especially in the financial and healthcare industries. Doing so would require extensive security policies at each location and would introduce a management nightmare. The alternative, backhauling traffic to the corporate DMZ, is not feasible. To read this article in full or to leave a comment, please click here
