![]() ![]() We teach the students how to set filters, add more columns for better fault analysis and how to export logs for further post-processing e.g. After the course the participant is able to use Wireshark efficiently for drop and throughput analysis.This should stem from previous exposure to design, troubleshooting or operations jobs in GPRS/UMTS/HSPA telecommunication networks. Participants should be already familiar with GPRS, UMTS and HSPA.Wireshark training is available as 'online live training' or 'onsite live training". ![]() The course is mainly targeted for Operators and UE-vendors which need to identify network problems leading to bad throughput and drops. Online or onsite, instructor-led live Wireshark training courses demonstrate through interactive discussion and hands-on practice the basics of the Wireshark protocol analyzer, and how to perform basic and advanced troubleshooting in small to medium size networks.Why Core Network can throttle the throughput down due to out-of-sequence delivery?. ![]() Why TCP Selective ACK's are counterproductive for TCP-Data frames but would be good for TCP-ACK out of sequence delivery of TCP-ACK's would be beneficial for the throughput if supported? Wireshark Pathways and Audience This software and certification is primarily aimed for security professionals or system administrators.Why can't the End-to-End RTT not go below a minimum value but increases when the TCP-Window Size increases? A too high Window Size fixes delay issues caused by the network but slows down the TCP-retransmissions and demands higher buffers in core and radio access network.What performance indicators can be seen in a TCP throughput graph?.How can a technician find out if the UE, NodeB, RNC, Core or the Internet are responsible for low throughput? Many times this requires TCP-tracing on the client, Gb/Iu-ps and on Gn/Gi-interface.Upon completion of these courses, you will be able to troubleshoot and effectively use the Wireshark software. ![]() It is used for network troubleshooting, analysis, software and communications protocol development, and education. Some of your questions that will be answered Wireshark is a free and open source packet analyzer.
