  • 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.
  • 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?

Who should acquire this book?

  • The book is mainly targeted for Operators and UE-vendors which need to identify network problems leading to bad throughput and drops.
