VMware Intros NSX

VMware Intros NSX

VMWare shows off the results of July 2012 acquisition Nicira at VMworld 2013-- the company launches NSX, a software-defined networking (SDN) platform turning switches, routers, firewalls and load balancers into software. 

The platform combines Nicira assets with VMware's own vCloud Networking and Security (vCNS), and promises to "unleash the power of network virtualisation" by decoupling the networking and security in Layers 2 - 7 from the underlying hardware. The result? More easily programmable, more agile and faster networking infrastructure, at least according to VMware.

The company also says NSX improves over the likes of its own VXLAN, with better scaling and interoperation with non-VMware hypervisors such as Microsoft HyperV and KVM.  Read more...

Vello Intros VellOS 7.0

Vello Systems claims to "shatter" the walls between optical, ethernet and virtual networking with VellOS 7.0, a scalable enterprise network OS uniting all networking technologies under a single vendor-agnostic platform. 

According to the company VellOS 7.0 allows customers to build and manage "highly adaptable, reliable and cost effective" infrastructure using a mix of networking technologies, with a common framework handling optical, ethernet and virtual networking planes. 

Based on a distributed Linux framework, VellOS incorporates standards-based RESTful APIs and GUI-style network policy and control, allowing users to mix and match OpenFlow-enabled network devices.  Read more...

Vendors Team up in SPB Interoperability

Vendors Team up in SPB Interoperability

Avaya, Alcatel-Lucent, HP and Spirent team up at Interop 2013 to present what they say is the first, live multi-vendor interoperability test using Shortest Path Bridging (SPB) technology. 

The test leverages the InteropNet backbone network to connect equipment at each participant's booths-- namely an Alcatel-Lucent OmniSwitch 6900 LAN switch, Avaya Virtual Services Platform 9000, HP 12500 series switches and Spirent TestCentre. 

SPB is an open and extensible fabric networking technology. Standardised as either 802.1aq (IEEE) or RFC 6329 (IETF), the technology simplifies network creation and management by demanding service provisioning only in the edge of the network. Using the Intermediate System to Intermediate System (IS-IS) protocol, SPB dynamically builds and maintains network topology between nodes and establishes a multi-path  traffic distribution fabric.  Read more...

Gefen’s Daisy Chain System: Up to 100 Displays

Gefen’s Daisy Chain System: Up to 100 Displays

Gefen’s Daisy Chain HD System creates a large infrastructure for wiring displays using CAT-5 cable. The system includes sender, splitter and receiver units—all interconnected in a daisy chain concept. All three units work together to extend 1080p full HD with RS-232 and IR control signals using the same CAT-5 cable.

“This is an evolutionary new daisy chain concept for many commercial applications, particularly digital signage-type video walls,” says Hagai Gefen, president, Gefen. “This solution uses Video over IP technology to route hi-def video to 100 displays and is a great fit for any commercial applications that use multiple displays such as airport terminals.”

Similar to a tree scenario, the system uses splitters to create new “branches.” Users can create up to 10 branches each supporting ten displays.

Individual displays can be mounted next to each other or up to 100 meters apart. Source video is sent to the sender then over a single CAT-5 cable to the splitter. The splitter outputs two signals: one that connects to a receiver and display; and another that connects to another splitter. Each splitter also provides one HDMI output for a local display connection. Read more...

Big Names Take on SDN

A number of vendors join the Linux Foundation in an industry effort to create a standard open-source software-defined networking (SDN) platform-- forming the OpenDaylight Project. 

Project members include Cisco, IBM, Citrix, Juniper Networks, VMware, Microsoft, Red Hat, Intel, Brocade, Big Switch Networks and Arista Networks, among others. 

According to the Linux Foundation “OpenDaylight unites technology industry leaders to establish the largest SDN open source project to date, with the goal of a common and open SDN platform for developers to utilise, contribute to and build commercial products and technologies upon.” Read more...
