SubscribeSolves Quality of Service Issues in Tactical Networks
Ultra Electronics-DNE Technologies, a provider of tactical voice and data communication solutions, announces the release of its PacketAssure product line, a new series of products designed to deliver voice and video IP network traffic over constrained US military network links as simply and reliably as time-division multiplexers.
DNE's PacketAssure line provides superior Quality of Service (QoS) and eases congestion by selectively identifying low-priority traffic for retransmission, allowing the PacketAssure to reliably run time-critical Internet Protocol (IP) traffic over limited bandwidth in support of high-speed IP radios and modems. Legacy circuit interfaces are also offered, enhancing the transition to tactical IP Network-Centric communications by integrating currently deployed equipment, including legacy Type 1 encryption, over emerging IP networks.
DNE's new PacketAssure products support simple and unique QoS policing by applying priorities to various traffic segments, preserving the quality of video and voice communications while supporting the data throughput efficiencies of dynamic packet networks. The PacketAssure line maintains a separation of Ethernet traffic segments to better assure information security without the need for Virtual Private Networks (VPNs) and their associated overhead and complexity. PacketAssure greatly simplifies configuring IP QoS policies and does not require a detailed understanding of buffer sizing and queue operation.
Ultra Electronics-DNE Technologies' Vice President of Sales and Marketing, Charles Reese, commented, saying, "The PacketAssure provides transition support to the US Military by supporting a variety of traffic services, but in a box that is much simpler to configure and adapt than most IP routers." He added, "Commercial IP-based routers can interface with the PacketAssure to deliver reliable service quality during congestion periods and improve immunity from information security threats.
PacketAssure supports Connection Admission Control (CAC), which enhances IP router operations, protecting time sensitive traffic by selecting lower priority packets for retransmission before they enter the buffering and queuing system." PacketAssure further enhances the transition to IP Network-Centric communication with optional legacy circuit interfaces. These interfaces encapsulate data into IP packets and then apply a priority to assure reliable operation of circuit devices over the IP network, permitting existing applications to operate using the emerging IP infrastructure.
Ultra Electronics-DNE Technologies' President and CEO, William Gill, Jr., noted, "PacketAssure makes the DoD's vision of Network Centric Warfare a reality. It resolves two important issues that have been plaguing the acceptance of the 'All-IP' network: Type 1 encryption support, and congestion relief in a converged network." He added that its compact size also makes it an attractive addition to tactical networks.
DNE's PacketAssure line is available in two models to support a spoke and hub network topology. The smaller TL model supports two option slots, which may be configured with a four-port Ethernet or a four-port serial interface, while the larger EX model, supports six option slots, offers redundancy, and can act as a hub for the TL models. Configurations start at under $20,000 and the PacketAssure is patent pending.
