Azteca Comunicaciones Colombia Picks Ericsson for IP


Azteca Comunicaciones Colombia has selected Ericsson's IP network equipement to deliver broadband services to more than 397 municipalities under Colombia's national broadband initiative. The broadband services will be delivered using Wi-Fi and point-to-multipoint wireless access.

The network will include Ericsson's flagship SSR 8000 family of Smart Services Routers, deployed as core routers; SmartEdge Multi-Service Edge Routers; the SPO 1400 family of Packet Optical Transport Platforms (POTPs); and Ericsson Wi-Fi access points, controllers and management.

"This contract is a major endorsement of our 4th generation IP network solution and marks the beginning of a new partnership between Ericsson and Azteca Comunicaciones Colombia. The solution will enable Azteca Comunicaciones Colombia to offer a rich suite of differentiated services and the scalability of the platforms will ensure the ability to meet future traffic and subscriber growth targets," stated Jan H├Ąglund, Head of IP and Broadband, Ericsson.

Brocade's Latest VDX Data Center Ethernet Fabric Scales to 384,000 VMs

Brocade has expanded its set of VDX fabric switches for the data center with a new model designed for enterprises and service providers striving to both simplify and scale-out their data center infrastructure.

The modular Brocade VDX 8770 Switch is built to support the largest data centers with highly virtualized environments. The Ethernet fabric enables faster virtual machine (VM) migrations through zero-touch VM discovery, VM mobility and VM port configuration migration. Using VCS fabrics, Brocade said its customers can manage dozens of switches as a single logical device. New switches will self-provision when they are connected to the fabric.

The Brocade VDX 8770 enables a single VCS fabric to scale up to 8000 switch ports with up to 384,000 VMs attached to the fabric. This is 20 times the scalability of the leading competitor, according to Brocade. The Brocade VDX 8770 also delivers the industry's lowest port-to-port latency at 3.5 microseconds across all 1 Gigabit Ethernet (GbE), 10 GbE and 40 GbE ports -- half the latency of the nearest competitor.

The Brocade VDX 8770 is built with a 4 Tbps backplane, enabling the chassis to support future technologies such as dense 100 GbE. Brocade said the VDX 8770 is also engineered for emerging Software-Defined Networking (SDN) architectures, with flexible hardware support for network virtualization through technologies such as VXLAN overlay networking.

The Brocade VDX 8770 is priced at $65,000 ($833/10G port).

Brocade Positions MLXe for SuperCore Routing with SDN


Brocade introduced a 24-port 10 Gigabit Ethernet (10 GbE) module that enables its MLXe Series routers to scale up to 768 ports of 10 GbE in a single chassis.

Brocade is positioning the MLXe router for large-scale service provider "Supercore" networks and Internet data center cores requiring high port density, scalable MPLS, rich routing and deep buffering capabilities. The platform can be used to create highly scalable BGP-free MPLS "Supercore" networks optimized for high-speed transport and fast convergence. Brocade said that by reducing the number of devices and eliminating IP routing from the core of the network, providers can greatly simplify their architectures and reduce both capital expenditure and operational costs.

The Brocade solution is powered by its fourth generation MaxScale-160 Packet Processors, which pack 1.38 billion transistors using 45nm technology. The router's 10 GbE density can be coupled with Brocade 100 GbE technology to drive next gen core networks.

Brocade is also working to integrate SDN and OpenFlow in the MLXe to control individual traffic flows up to 100 Gbps.  The company said this will maximize network resource utilization and improve traffic control to deliver differentiated SLAs.

For large data centers operators, the 768-port density achieved with the new 24-port 10 GbE module enables consolidation at the core of the network. The Brocade MLXe router delivers advanced Layer 3 switching capabilities and full-feature support for access control, routing and forwarding with 64-port Link Aggregation (LAG) capacity.  The platform complements Brocade VCS Fabric technology running on the family of Brocade VDX switches in the access and aggregation layers.

Significantly, Brocade is offering support for OpenFlow in Hybrid Mode, enabling the 10 GbE and 100 GbE Brocade MLXe solutions to integrate SDN with existing IP/MPLS networks .Brocade ADX platforms are also optimized for SDN, providing an application services fabric with a unified control plane and an API for resource assignment, enabling customized orchestration and provisioning of both physical and logical resources.

"Network operators are challenged to scale their networks and manage increasing complexity -- with more routers, more subnets and massive dynamic flows," said Ken Cheng, vice president of Service Provider and Application Delivery Products at Brocade. "The Brocade MLXe Core Router with the new 24-port 10 GbE module and industry-leading SDN technology will enable them to significantly scale their core networks to do more while greatly reducing network complexity and cost."

Brocade also released new OS software for its ADX Application Delivery Switches, delivering a new multitenancy capability. This carrier-grade multitenant architecture isolates customers or applications with dedicated hardware allocation of application delivery resources. A Brocade Network Subscription capacity-on-demand subscription model that aligns infrastructure cost to business needs, gives providers a highly elastic infrastructure acquisition and deployment model that matches the way they deliver cloud services.

  • In May 2011, Brocade first introduced its MLXe, featuring a 15.36 Terabits per second (Tbps) fabric for core networks.  The Brocade MLXe router is offered in 4-, 8-, 16- and 32-slot configurations.  Brocade also introduced a Multi-Chassis Trunk (MCT) innovation to simplify data center networks and increase resiliency for customers moving to 10 GbE-enabled servers. In addition, a new Brocade Network Advisor management solution provides visibility for Brocade Fibre Channel, Fibre Channel over Ethernet (FCoE), wireless, Ethernet switching, and MPLS networks.

NEC Develops Optical Switching Handling 20 Tbps Signals


NEC has published a technical paper on its development of an optical switching device capable of changing between a variety of transmission paths (routes) using silicon photonic technologies (optical circuits using silicon-based semiconductors) with ultra high capacity 20Tbps optical signals. NEC said its prototype device has demonstrated high quality optical switching, without signal deterioration, of optical super channels (20Tbps) and 100 Gbps DP-QPSK.

NEC describes its device as a transponder aggregator (TPA) that supports multiple signal formats and features a color-less, direction-less, contention-less (CDC) Reconfigurable Optical Add/Drop Multiplexer (ROADM) capabilities.

"NEC's new developments utilize TPA and produce compact modules featuring silicon integrated optical switches that boast 150 elements on a single chip. This enables the switching of large 48-unit transponders between 8 routes while capitalizing on CDC functions," said Naoki Nishi, General Manager, Green Platform Research Laboratories, NEC Corporation. "We now anticipate the incorporation of this TPA on a single board as well as the reduction of module size and power consumption by roughly 90% when compared to optical switches based on conventional silica optical waveguides. Furthermore, the optimized drive of each switch will enable us to provide high speed, stable signal switching."

NEC is presenting its research at this week's Photonics in Switching 2012 (PS 2012) conference in Corsica, France, and at ECOC 2012 in Amsterdam, Holland.
