Acme Packet Session Border Controllers Interface to Policy Servers from Alcatel, Camiant, and Operax; Expands SLA Assurance Capabilities in Alignment with Next-Generation Network Architectures.BURLINGTON, Mass. -- Acme Packet(R) today announced support for policy servers from Alcatel, Camiant, and Operax by its Net-Net(R) family of session border controllers. The solutions from Acme Packet and these partners address the need for QoS- and bandwidth-on-demand for real-time interactive IP-based voice, video and multimedia sessions. Each of these partners' products satisfies a unique set of requirements in next-generation DSL DSL in full Digital Subscriber Line Broadband digital communications connection that operates over standard copper telephone wires. It requires a DSL modem, which splits transmissions into two frequency bands: the lower frequencies for voice (ordinary , cable, wireline and wireless networks. In these solutions, the Acme Packet Net-Net session border controller performs session admission control in conjunction with policy servers - session acceptance or graceful rejection using SIP signaling messages - based upon its requests to the policy server for bandwidth and QoS on a per call basis. These requests use standards-based COPS and SOAP/XML messages. The policy server authorizes the sessions, reserves bandwidth and QoS, and provisions the transport equipment, such as IP edge routers, DSL BRAS, and cable CMTS (Cable Modem Termination System) A computerized device that enables cable modems to send and receive packets over the Internet. It inserts IP packets from the Internet into MPEG frames and transmits them to the cable modems via an RF signal. systems for enforcement. Acme Packet's policy server support complements its existing SLA (1) (StereoLithography Apparatus) See 3D printing. (2) (Service Level Agreement) A contract between the provider and the user that specifies the level of service expected during its term. assurance features including session admission control based upon bandwidth constraints, session agent constraints and observed QoS; signaling-controlled QoS packet marking and mapping; QoS reporting and routing by codec type. "This new functionality provided by Acme Packet and our partners offers service providers a centralized bandwidth management approach with policy enforcement by the transport equipment," commented Seamus Hourihan, Vice President Marketing and Product Management at Acme Packet. "Combined with our session border controller's existing capabilities, we enable providers to deliver high-quality, primary line voice residential services and satisfy the stringent SLA requirements of business customers for not only voice, but business-critical, real-time interactive video and multimedia sessions." Policy servers critical to SLA assurance in NGN (Next Generation Networks) An umbrella term for mixed voice and data networks running over the IP protocol. See IP Multimedia Subsystem. Unlimited bandwidth and QoS, even in broadband next-generation networks, is a myth. This is especially true in access networks where service providers squeeze higher returns from their CAPEX with oversubscription Oversubscription The excess number of shares or bonds that investors want to buy but are not available due to high demand. ratios ranging from 50 to 500 to 1. Another myth is that interactive voice and video is just another form of data. While data can tolerate significant delay and jitter, person-to-person communications just cannot. In converged IP networks mixing interactive voice and video communications with bandwidth-hogging applications like pay-per view video, IPTV (Internet Protocol TV) Also called "TV over IP," IPTV delivers scheduled TV programs and video-on-demand (VOD) via the IP protocol and digital streaming techniques used to watch video on the Internet. and gaming, and packet loss-intolerant applications like e-commerce or e-business, the problem becomes very acute. Consequently, policy servers are recognized as critical elements in all next-generation network architectures including: --DSL Forum TR-059 Policy Server --ETSI TISPAN TISPAN TIPHON (Telecommunications and Internet Protocol Harmonization over Networks) and SPAN (Services and Protocols for Advanced Networks) (ETSI) Resource and Admission Control Subsystem (RACS RACS Royal Australasian College of Surgeons RACS Resource and Admission Control Sub-System RACS Russian Association for Canadian Studies RACS Revenue Accounting Control System RACS Robert's Anime Corner Store RACS Real Aero Club de Santander ) --IP Multimedia Subsystem (IMS (1) See IP Multimedia Subsystem.

Alcatel 5430 Service Resource Broker (SRB) is a server-based application that enables service providers to differentiate their offerings through bandwidth on demand and quality of service (QoS). The bandwidth-on-demand feature allows service providers to address the needs of users who want the benefits of low-cost broadband services, but who temporarily need to increase bandwidth on a pay-per-use basis to support a service or a communication, or to quickly download a large file. These bandwidth increases can be initiated automatically by the application or by the end user through a boost button. The QoS feature of the SRB allows service providers to check on a per-flow whether adding a new premium flow would not create congestion The condition of a network when there is not enough bandwidth to support the current traffic load. congestion - When the offered load of a data communication path exceeds the capacity. with existing premium traffic in their DSL network. In this way the low latency and zero packet loss of premium traffic can be guaranteed at all times. Camiant QBUS Multimedia Service Controller (MSC (1) (MSC.Software Corporation, Santa Ana, CA, www.mscsoftware.com) Founded in 1963 by Richard H. MacNeal and Robert G. Schwendler, MSC is the world's largest provider of mechanical computer aided engineering (MCAE) strategies, simulation software and services. ) allows the rapid deployment of any QoS enabled broadband application, assuring a high quality customer experience. The QBUS MSC allows operators to prioritize service delivery based on factors such as subscriber-tier, application and network status. It then dynamically directs the appropriate network elements to provide service according to the operator's policies, providing opportunities to increase the average revenue per subscriber. Operax Triple Play is a service and bandwidth control system for broadband access and aggregation networks. It is based on Operax patented technology that enables deployment of attractive voice, video, and data services that meet customer expectations on quality and price.
