Minimum = 11ms, Maximum = 37ms, Average = 18ms Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),Īpproximate round trip times in milli-seconds: My ping command displays the RTT for each packet sent and returned below. After that, the copy gets deleted and resources are released for future use.ĪLSO READ: Steps to troubleshoot with TTL in Wireshark with Examples Whenever a sender transmits a packet, it saves a copy of the packet int its buffer and it stays there until receiving side acknowledges that it has received the packet. The lost packets are recovered by retransmissions and acknowledgments while sequence numbers are used to determine correct packet reordering in the receiving side. The protocol offers packet delivery guarantees, even if some of the packets have been lost during the transmission.

TCP is one of the reliable protocols working in the transport layer, in terms of Open System Interconnect (OSI) model.

How to filter TCP Retransmissions with Wireshark.

Analysing TCP Retransmission Timeout (RTO).

I ran a tcpdump and found out that request from the load balancer is reaching tomcat servers, however tomcat server is sending numerous re-transmission calls back to the load balancer. However we can access tomcat servers directly using server IPs and 8443 port. Nothing is logged in to tomcat logs indicating any requests have received from the load balancer. We are having trouble accessing services through load balancer.

We have a load balances in front of 2 apache tomcat servers that are listening on port 8443. We have enabled TLSv1.2 on Apache tomcat.
