GL Announces PacketScan(TM) with Video QoS
GL Communications Inc. announced today the release of its new PacketScanTM software with Video QoS feature.
- (1888PressRelease) September 21, 2010 - Gaithersburg, Maryland, USA - GL Communications Inc. announced today the release of its new PacketScanTM software with Video QoS feature. Addressing the news conference, Mr. Vijay Kulkarni, CEO of the company said, "PacketScan™ is a powerful software tool that features real-time capture and monitoring of IP, VoIP, and now IP based Video traffic:
•segregates, captures, and collects statistics on VoIP calls (H.323, SIP, MGCP, Megaco, T.38, and others),
•monitors QOS (quality of service) on voice and video calls,
•permits analysis of adherence to protocol standards for the system under test or observation,
•provides graphical presentation of analysis, including ladder diagrams of protocols
The application can also monitor, report, analyze, and capture calls for infinite time, limited only by the finite space of your hard disk or network hard drive! It can work with PacketScanWEB™, a central monitoring system for a comprehensive view of network performance. It features rich graphics, ladder diagrams, CDRs (Call Data Records), and compatibility with almost every CODEC".
He added, "We continue to improve PacketScan™ with features that our customers request, and as a result the application has been now enhanced to send H.323 CDR to central Database. This permits monitoring network performance through web based clients such as PacketScanWeb™. Also the application can now calculate Video Statistics such as Media Delivery Index for video sessions. The Media Delivery Index (MDI) is a set of measures that can be used to monitor both the quality of a delivered video stream and to show system margin for IPTV systems by giving an accurate measurement of jitter and delay at network level (Internet Protocol, IP), which are the real causes for quality loss. The Media Delivery Index is typically shown as two numbers separated by a colon the Delay Factor (DF) and the Media Loss Rate (MLR)".
Mr.Kulkarni further added, "New PacketScan™ with Video QoS capability addresses customers long felt need of Video Call Quality checking in VoIP networks".
Other Important Features:
•Protocol summary information and binary frame data can be sent via TCP-IP connection to a Database Loader to load data into a database. The provided options are:
i.Send Call Detail Records: If this option is selected, all the call detail records will be sent to the remote database.
ii.Send Traffic Summary: If this option is selected, all the details in Summary View Packet Data Analysis will be sent to the remote database. Traffic Summary sent to central database now includes SIP-Origination IP address, i.e., Callers IP address, Destination IP address, Packet type, and so on.
•SIP Performance Metrics
Additional SIP performance metrics have been provided in statistics counters for Sip calls and are: Session Establishment Ratio, Session Establishment Effective Ratio, Session Defects, Ineffective Session Attempts, Session Completion Ratio, Session Request Delay, Session Disconnect Delay and Registration Request Delay.
•Call Summary Tab
In Packet Data Analyzer (PDA) portion of PacketScan™, a new tab has been added that displays Signaling and Audio Parameters for the selected call (SIP, H323, MEGACO Calls).
•Save Call
Save Call feature has been enhanced to save the captured trace along with a PCAP compatible file.
•Alert Summary
PacketScan™ has been enhanced to generate alerts when a particular vital parameter goes beyond a specified value. The user can specify the criteria based on which the alerts are to be generated. The alerts can be set by selecting an option in Alert Summary and in Triggers and Action Settings.
Alert Summary tab provides summary of the each alerts that have occurred during the analysis. Each summary has the following columns: Call#, Protocol, Message, Type, Threshold, Value, Caller, Callee, CallId.
•T.38 Analysis
T.38 has been enhanced to reassemble the fragmented data and to identify the T.30 message from it. Identified T.30 message is displayed in the T.38 ladder diagram.
•VQMon Setting
VQMon Setting is enhanced with an option to select the Japan or North America International standard code. These standards are followed in calculating MOS scores based upon R-Factor scores.
•There is display now for bandwidth consumption for VoIP traffic and also for protocols like SIP, RTP, MEGACO and H.323. All are displayed in PDA.
About GL Communications Inc.,
Founded in 1986, GL Communications Inc. is a leading supplier of test, monitoring, and analysis equipment for TDM, Wireless, IP and VoIP networks. Unlike conventional test equipment, GL's test platforms provide visualization, capture, storage, and convenient features like portability, remotability, and scripting.
GL's TDM Analysis & Emulation line of products includes T1, E1, T3, E3, OC-3, STM-1, analog four-wire, and analog two-wire interface cards, external portable pods, and complete system solutions. Capabilities include voiceband traffic analysis and emulation across all traffic types (voice, digits, tones, fax, modem), all protocols (ISDN, SS7, GR-303, Frame Relay, HDLC, V5.X, ATM, GSM, GPRS, etc.), and with capacities up to thousands of channels.
GL's VoIP and IP products generate / analyze thousands of calls / traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax using G.711, G.729, AMR, EVRC, GSM and a range of other codecs. Additional features include visual analysis, real-time listening, and recording. The product line also includes Ethernet / IP Testing capability that simulates and checks frame transport and throughput parameters of Ethernet and IP networks, including delay, errors and other impairments.
GL's Voice Quality Testing (VQT) product line complements all of GL's products. Using ITU-standard algorithms (PAMS, PSQM, and PESQ), GL's VQT provides a widely excepted solution across the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, VoIP, Wireless, and Landline) are all available.
GL's Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA and UMTS networks. Connections can be made to any wireless phone with automated call control, GPS mapping and real-time signal measurements.
GL's Echo Canceller testing solutions provide the broadest range of simulation and analysis, including compliance testing per G.168 and G.160 across TDM, IP, VoIP and Wireless networks. GL's wireless VQT solutions help assessing impairments to voice quality such as poor mobile phone quality, voice compression and decompression algorithms, delay, loss and gain in speech levels, noise, acoustic and landline echo, and other distortions are easily assessed and accurately measured.
GL's Handheld data testers can test a wide variety of communications facilities and equipment including T1, fractional T1, E1, fractional E1, T3 and E3 modems, multiplexers, CSU, DSUs, T1 CSUs, DTUs, NTUs and TIUs and more. The testers provide convenience, economy, and portability for almost any interface, including RS232, RS-422, RS-530, X.21, T1, E1, T3, E3, and many others.
GL's Network Surveillance and Monitoring products include Probes for TDM, IP, VoIP, ATM, and Wireless networks. An open standards based approach provides a scalable, feature rich, real-time access to network intelligence. Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
