Active Broadband Networks unveils software-defined networking controller
Aug 23, 2013 (MarketLine via COMTEX) --
Active Broadband Networks, a supplier of software-defined broadband service management solutions, has announced that its Dynamic Broadband Service Manager, or DBSM, now incorporates software-defined networking, or SDN, technologies that transform the delivery of broadband services.
This new SDN controller solution reportedly allows network operators to easily deploy an intelligent, software-defined service layer for the common control and active management of broadband services across different types of access networks, including cable, DSL, FTTH and WiFi.
"The increasing cost and complexity of managing broadband services is a result of the functional constraints of proprietary software embedded in network elements and the performance limitations of existing OSS/BSS solutions," said Adam Dunstan, CEO of Active Broadband.
"Moving control plane and performance-critical network functions into SDN software running on high-performance server platforms will transform how broadband services are offered and allow network operators to tailor services to the individual needs of subscribers. The DBSM is the first of a new breed of SDN controller for service management applications to gain full visibility into and direct control over subscriber traffic flows at the broadband edge by exploiting the capabilities of SDN-enabled network elements."
Operating as an SDN controller, the DBSM uses the OpenFlow protocol to dynamically activate services and manage subscriber traffic flows through SDN-enabled network elements at the broadband edge. OpenFlow structures communication between the control and data planes of SDN-enabled network infrastructure, and allows the DBSM to directly implement service management policies for fine-grained control of subscriber traffic flows, the company said.
The DBSM incorporates the IPFIX protocol for rapidly collecting network stream telemetry data on traffic flows and network utilization for real-time service management applications that require timely and accurate information about bandwidth consumption and network conditions. IPFIX is an Internet Engineering Task Force (IETF) protocol that represents the state of the art in network telemetry data collection. It uses a highly efficient streaming protocol- the Stream Control Transmission Protocol (SCTP) - and specifies a uniform and extensible method for collecting IP flow information from elements in any type of IP network, the company reported.
The DBSM can manage and control subscriber traffic flows through any SDN-enabled network element that supports OpenFlow and IPFIX. Active Broadband will be engaged in interoperability testing and demonstrating its new SDN controller at upcoming industry events by using OpenFlow to control Open vSwitch software running on commercial off-the-shelf (COTS) Intel-based hardware platforms capable of multi-gigabit throughput. Open vSwitch, which can also export network stream telemetry data using IPFIX, is Linux-based open source software that is also portable to ODM switching platforms and is a key technology in the OpenStack cloud computing platform, the company added.
