LTE - Troubleshooting with Wireshark
Hi,
Really looking for this new book:
https://www.inacon.de/bookstore/book..._wireshark.php
- ow 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.
- What performance indicators can be seen in a TCP throughput graph?
- 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.
- 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?
- Why Core Network can throttle the throughput down due to out-of-sequence delivery?
Product Details:
- Paperback
- 366 Pages
- over 160 Illustrations and Tables
- ISBN 978-3-936273-78-6
Thanks.
