Acme Packet Extends Service Accountability Toolset

Acme Packet introduced a number of management extensions for its Net-Net family of session border controllers (SBC), multiservice security gateways (MSG) and session routing proxies (SRP). These enhancements include support for Acme Packet products by IBM Tivoli Netcool , as well as Acme Packet product enhancements: voice quality measurements using R-factor and MOS scoring; and customizable call detail records (CDRs) with any SIP message content.

Using Netcool, users can now manage Acme Packet products in addition to other network and service infrastructure elements. This support includes two Netcool applications: Netcool/OMNIbus, IBM's real-time event and fault management tool; and Netcool/Proviso, IBM's carrier-class performance management and service-level reporting software.

Acme Packet session border controllers (SBC) now calculate and report R-factor and mean opinion score (MOS) information for SIP calls. R-factor is a calculation of voice quality that uses the "E-Model" described in ITU-T G.107, taking into account QoS statistics as well as other voice impairment factors. MOS, the widely-accepted scalar representation of voice quality, is derived from the calculated R-factor. Reports may be generated either mid-call on a periodic basis or in end-of-call Call Detail Records (CDRs), which are compiled from statistics collected over the duration of the call.

For interim call quality reporting, R-factor and MOS scores are periodically calculated during the call, compiled into comma-separated value (CSV) formatted files and transferred to network management tools such as Infovista VistaBridge, which are able to generate real-time graphical representations of call quality data based on the R-factor calculations for each bi-directional media RTP flow. End-of-call quality reports are included in the SBC's RADIUS Call Detail Records.

R-factor and MOS scoring extend Acme Packet's portfolio of session quality of experience (QoE) measurement tools. They complement network Quality of Service (QoS) measurements of packet latency, jitter and loss, as well as signaling-based Answer Seizure Ratio (ASR) measurements of call completion rates. These tools enable more efficient troubleshooting, isolation and resolution of network and signaling infrastructure issues when call quality levels slip to sub-optimal levels and provide quantitative validation of service level agreement (SLA) compliance.

User-customizable CDRs allow Acme Packet customers to define vendor-specific attributes (VSAs) used to populate call detail records (CDRs) with content derived from SIP messages. In addition to the 140 predefined CDR fields already supported by the Acme Packet Net-Net family, 30 new fields can be populated with content from any user-defined portion of SIP messages, including SIP header information, Session Descriptor Protocol (SDP) parameters, embedded Extendible Markup Language (XML) and others.

A practical example of this important capability would be a service provider's ability to generate customized billing statements from Acme Packet CDRs that are the result of proprietary information generated by SIP-enabled equipment. Equipment vendors often incorporate proprietary fields in their SIP implementations, and service providers are unable to incorporate this information into useful accounting data due to its proprietary nature. Acme Packet's ability to modify the information and incorporate it into CDRs results in the service provider's ability to use the proprietary data in customer billing statements without requiring expensive changes to their own systems or forcing peering partners to make alterations to their own networks or back-end systems.

France Considers Licensing of 2.1GHz Spectrum

ARCEP, France's official telecom regulator,

will launch a public consultation over what to do with the remaining frequencies in the 2.1 GHz band. The assignment of these frequencies is an important issue, especially for a new entrant candidate, which will be able to gain access to low frequencies in the 900 MHz band if it is authorized in the 2.1 GHz band.

Three outcomes are possible:

  • A procedure which reserves all frequencies to a new entrant based on conditions similar to those of the third application procedure

  • A procedure in several lots, some of which being reserved first to new entrants and others being available to both new entrants and existing operators

  • A procedure in several lots available to all operators.

Aktino's Ethernet/Copper Promises 90+ Mbps of Backhaul Capacity

Aktino introduced a new copper-based access solution that promises 90+ Mbps of capacity that could be used to transport either DS3 TDM/ATM or Carrier Ethernet. The solution, which combines features from Aktino's DS3 and Carrier Ethernet over copper product lines, addresses three key applications: Carrier Ethernet services, DSLAM backhaul, and cell site backhaul.

Aktino said its new product delivers either a DS3 or up to 90+ Mbps of Carrier Ethernet bandwidth throughout the entire CSA (Carrier Serving Area or 12,000 feet) and beyond. It switches from a DS3 to Carrier Ethernet product and back via a simple user command. It can deliver asymmetric services to cover their entire CSA with bandwidth of up to 90+ Mbps, or symmetric services of up to 90+ Mbps at shorter reaches, according to the company.

In tandem with this solution, Aktino is introducing an updated version of its 8-pair Ethernet solution, which provides 50 Mbps symmetric bandwidth at up to 5,000-foot reaches.

By configuring the product in asymmetric mode, a carrier can double the downstream bandwidth over Aktino's already high symmetric MIMO-on-DMT (Multiple Input, Multiple Out on Discrete Multi-Tone) bandwidth, and more than quadruple the bandwidth provided by G.SHDSL. Aktino is the only bonded copper solution vendor that offers asymmetric bandwidth capability.

Telstra Activates 3G Direct Tunnel with Ericsson

Ericsson said that by implementing 3G Direct Tunnel, Telstra starts to evolve its Next G network to a flat all-IP architecture that will both allow the network capacity to grow while lowering the cost of expanding the network to meet ever growing demand.

Ixia Develops 100 GbE Line-Rate Traffic Testing

Ixia plans to demonstrate an initial implementation of 100 Gigabit Ethernet (GbE) line-rate traffic generation and analysis at next week's NXTcomm08 in Las Vegas.

The Ixia proof-of-concept demonstration features a multilane distribution (MLD) architecture -- the new 100 GbE and 40 GbE physical coding sublayer (PCS) layer, which was recently approved as the baseline proposal by the IEEE 802.3ba task force. MLD enables network providers to bond multiple 10 GbE or higher-speed lanes into a single logical 100 GbE or 40 GbE link. The technology provides a means of "striping" a 100 Gbps flow into multiple "virtual" lanes, each with its own alignment markers.

Veraz Launches its iMN Multimedia Delivery Platform

Veraz Networks introduced its iMN Multimedia Delivery Platform, a compact switch that enables service providers to deliver TDM, VoIP and web services. The new platform, which is based on the same technology as Veraz's widely-deployed ControlSwitch, scales to 15,000 subscribers. The iMN integrates support for IP and TDM services, enabling legacy TDM switch upgrades, VoIP network peering, IP-based end user services and web applications, as well as WiMAX buildouts. The iMN is a carrier-grade, NEBS-compliant platform.

Veraz will offer its iMN as a packaged solution, pre-loaded with all required software, designed for easy deployment and management, right out of the box. For on-going support, Veraz provides network operators with a suite of e-learning and professional services training.

The iMN can also be customized with a number of value-added extensions including a complete prepaid billing application as well as Veraz's IP access and peering security solution. The company said its combination of these extensions with the platform's session routing engine, open interfaces and TDM interconnect capabilities provides operators with an easy to use advanced services platform. Other iMN extensions include Veraz's I-Gate 4000 media gateway platforms, Distributed Signaling Gateway and the verazVirtu softclient.

Veraz has also developed a special replacement program for service providers currently using Verso's Clarent softswitch. The iMN offer will enable existing Verso customers to maintain service offerings with a solution that will not only continue to grow but also with full support.
  • In May, Veraz Networks outlined key elements of its Multimedia Generation Network (MGN) architecture for helping service providers to rapidly deploy customized multimedia services while preserving and extending the capabilities of legacy application suites.

    Veraz's MGN architecture, which builds on the company's existing product set and the IMS framework, aims to open up the telecom service creation environment to partners and third-party developers. The network would be client-aware and seamlessly support multiple access network technologies to ensure consistency of service as well as service mobility. The company said that by eliminating the silo approach to service creation and delivery and replacing it with a unified service delivery and management platform, operators can quickly introduce new revenue generating services and lower the cost to deliver their existing services.

    Veraz's MGN architecture consists of three layers: Media, Control and Service Delivery, tied together by a unifying management layer.

XO and Infinera Demonstrate 100 Gigabit Ethernet

XO Communications and Infinera will team up to demonstrate 100 Gigabit Ethernet traffic in production-ready form over a live network at next week's NXTcomm08 show in Las Vegas. The demonstration will consist of an Ixia proof-of-concept 100 GbE test set generating and handing off a pre-standard IEEE 802.3ba 100 GbE signal to a 100 GbE interface on the Infinera DTN DWDM transport system. The 100 GbE signal will then be switched and transported by the Infinera DTN system from the show floor through XO Communications' long-haul DWDM network to Los Angeles. The 100GbE signal will then be looped and transported back to the Infinera booth in Las Vegas, where performance metrics will be monitored and viewable on the Ixia XM2 chassis.

In the NXTcomm08 demonstration, the 100 GbE signal is received from the Ixia test set and striped across ten 10 Gb/s wavelengths using Infinera's Digital Virtual Concatenation protocol, and then transmitted over the long-haul network by Infinera's Photonic Integrated Circuit (PIC)-enabled DTN platform, before being reassembled by the Infinera system at the other end. The Tributary Adapter Module (TAM) in this demonstration, which fits into today's Infinera 100 Gb/s Digital Line Module (DLM), is in a commercially-suitable form-factor and ready for development into a commercial product.
