Could anyone explain the main principe of tcp flow when making a session ?



I have take a tcp dump when i'm trying to browse a site. when I analyse the packet by wireshark, i have found many Three way handshake process for one site browse. is that considere as normal ? below the flow :



1-[SYN], 2-[SYN,ACK],3-[ACK], 4-GET/HTTP/1.1 , 5-HTTP/1.1 301 Moved Permanently (text/html), 6-[ACK],7-[ACK],8-[TCP DUP ACK6#1], 9-[SYN],10-[SYN,ACK], 11-[ACK], 12-Client Hello, 13-[ACK]

          The answer to your question is yes, it's normal. Modern web sites use multiple TCP streams to build the web page you see in your browser. Text and images can be downloaded concurrently, making the page load faster. Also, as you may notice, a single "page" may have components download from many different servers.

          A browser may open multiple TCP connections in order to simultaneously load different parts of a web page. Each TCP connection will need to run through the full TCP handshake process because it is a separate connection.



          If you look closely, you will see different source ports on each connection. A connection is identified by a pair of sockets (source and destination), each socket consisting of the IP and TCP addresses. If you change even one of the four values (source or destination IP or TCP addresses), then it is a different TCP connection, and the connection must be initialized.

          What visual should I use to simply compare current year value vs last year in Power BI desktop

          Image
          0 I have column SubToBind that shows current year ratio and column PY SubToBind which shows previous year ratio. How can I simply create a card that would be displaying them both in a nice way? Something like that: I cannot achieve that with regular card, I also tried Card with States by OKViz but also unable to see both values. In KPI visual - I dont like the word "Goal", it will confuse end users. Are there any cards or other visuals that would do the job?

Elle joue une octave plus haut que la trompette standard en si bémol. La plupart des trompettes piccolo sont conçues pour jouer dans les deux tonalités de si bémol ou la, en utilisant une branche d'embouchure différente pour chaque tonalité. Le tube de la trompette piccolo en si bémol a une longueur moitié de celle de la trompette normale en si bémol. Des trompettes piccolo en sol, fa, ut sont également fabriquées, mais elles sont rares.
