GL's PacketShark™

GL's PacketShark™ can tap packet networks and capture Ethernet packets at wire speed, i.e., in optical or electrical interfaces up to 1 Gb/s and selectively filter the captured traffic based on specified criteria.

Gaithersburg, Maryland (PRWEB) September 04, 2012

GL Communications Inc. announced today the release of its product PacketShark™ A handheld hardware that can tap packet networks and capture Ethernet packets at wire speed.

Speaking to reporters, Mr. Robert Bichefsky, Senior Manager of Product Development for the company said, “GL's PacketShark™ is a portable product that can tap packet networks and capture Ethernet packets at wire speed, i.e., in optical or electrical interfaces up to 1 Gb/s and selectively filter the captured traffic based on specified criteria. Packets are transmitted through two ports and the packets that are traffic compliant with one of the filters is sent to a packet analyzer, such as Wireshark or GL's PacketScan™ for detailed packet analysis. Alternatively, the traffic can be even sent to a memory card (SD) and later analyzed offline.”

He added, “PacketShark™ is an invaluable tool for on-field simultaneous capturing from two interfaces, analyzing 100% streams without any delays, and filtering/aggregating required packet streams at wire speed. It overcomes most of the limitations of protocol analyzers running on Laptops or PCs that are too slow to capture live Full Duplex traffic at wire speed. It is generally preferred over "mirror" ports and traditional "taps" in providing aggregated traffic output and mobility.”

Mr. Bichefsky further added, “PacketShark™supports all the features of high-end taps in a small, battery operated instrument, weighing less than 1.2 kg, and providing mobility and storage capacity to reach any point in the network. It provides INSTANT ON features - no PC required.”

Important Features

· Ability to capture packets at any point of the Network
· Wirespeed filtering with zero loss and zero delay - Equipped with a unique Zero Delay technology that ensures every packet goes through without delay (even if power is lost)
· Capture in the field and analyze in the office - Field storage of captured data using an external storage device (SD memory card) in PCAP format.
· Copy and forward matching packets to the drop LAN.
· Traffic and Signal Regeneration
· Sixteen (16) simultaneous filters can be applied to the traffic.
· Firmware filters to identify traffic MAC, IP, UDP or TCP flow.
· Centralized or distributed deployment
· Jitter-less time stamps
· Invisible when connected (Undetectable): no IP no MAC
· Improves efficiency and the performance of the protocol analyzer by adding mobility, capture filters and local storage
· Erred frames, fundamental feature for troubleshooting: FCS, runts, fragments, etc

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, OC-12, STM-1, STM-4, 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, LTE, etc.), and with capacities up to thousands of channels. Our newest products provide astonishing capacity and capture capability up to and including gigabit speeds.

GL’s VoIP and IP products generate / analyze thousands of calls and traffic simultaneously with traffic types such as frames, packets, voice files, digits, video, tones, noise, and fax.  Almost all codecs are supported including G.711, G.729, AMR, EVRC-A,B,C, GSM, iSAC,  and many more. 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 accepted solution for assessing voice quality in the telecom industry. Voice Quality Testing across multiple networks (T1, E1, T3, E3, OC-3, OC-12, VoIP, Wireless, and Landline) are all available.

GL’s Wireless Products perform protocol analysis and voice quality assessment on GSM, CDMA, UMTS, and LTE 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 line and acoustic echo. GL’s compliance testing per G.168. G.167, and P.340 across TDM, IP, VoIP and Wireless networks is widely accepted in the industry.

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 characteristics.  Centralized or distributed access, efficient transport and database loading allow compatibility with 3rd party and standards based monitoring systems.
