I am analysing a TCP Chat between workstations and a HTTP server (172.23.22.205).
I have noticed that some users have gotten problems to access the HTTP Server. So slow to put or get image files.
The communication way is the following:
Workstation -> router -> MPLS network -> router -> firewall -> packeteer -> router -> MPLS network -> router -> HTTP Server (172.23.22.205)
In the last traffic captured (in 10 minutes), I got the following notifications:
- 3850 TCP Chats
- 201 Warnings: like "TCP Previous segment lost", "TCP out of order segment"
- 586 Notes: like "TCP Dupl ACK", "TCP Retransmission"
Is that OK or do I have to improve the network ?
I think that the server is not supporting so many connections.
I saw that some ICMP packets was lost (1 or 2%) when I start a ping from firewall -> router -> MPLS network -> workstation
Please, help me in this issue.
