All the newer incoming TCP/IP-packets have to be buffered until the very missing/dropped TCP/IP Packet is re-transmitted by the Server and properly received by the Client.

Quick Logfile Analysis using “Expert Info”įor every new TCP/IP Packet the Client sends a Duplicate ACK pointing out that a certain older TCP/IP-packet is still missing.

unnecessary retransmissions, Advantage when UTRAN or PCU do not stall the forwarding of TCP-ACK's to the TCP-Server and thus allow out-of-sequence delivery of TCP-ACK's if they hang in retransmissions due to RLC-AMĪ TCP aware UTRAN or PCU would be beneficial for the throughput if TCP-ACK's are handled preferred

Issue of lower layer retransmissions while Selective ACK's invoke TCP-Retransmissions resulting in “double” resp.Pro's and Con's of Selective Acknowledgments.Impact of Duplicate ACK's & Fast Retransmissions on Subscriber Throughput.Linux computer are able to prioritize the sending of TCP-ACK's before TCP-data are sent Upload throttles down the download due to Windows-PPP issue (no prioritization of TCP-ACK's),.Concurrent Download and Upload leads to lower throughput.laptop) should be set to a certain value matching the RTT of the system The E-t-E-RTT cannot fall below a minimum value but increases easily Throughput should be preferably limited by the UE's Capability's Specifics of a Wireless System like GPRS, UMTS or LTE:.Bandwidth Delay Product: Throughput = Window Size / RTT.Window Size, Round Trip Time, Maximum Segment Size, Maximum Transfer Unit, Socket Parameter.3-way handshake, Receive Window Size of Client is critical, Reset a Connection.TCP Slow Start and Congestion Avoidance.Reviewing important TCP/IP Fundamentals.
