Excellent explanation! You should totally write a book about networking.

12:43 the source port for ip address C must be same in both process p2 and p3 which is 5775 but in p3 source port is written of port A 9157

At the end if the port number is 80 for all sockets within the server how can the server distinguish which socket can receive the data?

Hello sir, at the end of the video you said for the UDP demultiplexing, only destination port number is required but I think destination ip address is also required for connectionless demultiplexing
@The_Digamma 7 місяців тому
yeah you are absolutely right. In his textbook + slides, it is written correctly. reference slide: chapter - Transport layer, Page 17
@turkersubasi 24 дні тому
can anyone help me? On UDP protocol how does sender knows the destination port number?
@krishnaas5927 Рік тому
In the case when UDP is used, If many clients have the same dest port no. say 80 then they would goto the same socket in the destination server right? if so how would the server distinguish between the different packets received as obviously they are from different sources however in UDP only dest port and IP is mentioned, unlike TCP where src port and ip is also included.
@uditidas Рік тому
That's why UDP is connectionless as it only have the destination port to the destination server. It doesn't have other tuples destination ips and port as in TCP to identify it correctly and built a authentic connection.
@turkersubasi 24 дні тому
does sender choose dest port no arbitrarily?
@beepbeeblebrox3972 3 місяці тому
what does the P stand for? program? port?
@jiteshmeghwal2645 3 роки тому
Sir does this mean that multiple processes can share the same tcp port ?
@abdullahwaris1275 3 роки тому
Yes, as the arriving datagrams can be demultiplexed based on the senders ip and port number as well.
@JimKurose 2 роки тому
Abdullah is exactly right. On a web server, multiple processes proving web service will share the same TCP port number (80). Jim
@BipinJethwani Рік тому
@@JimKurose I think you should talk about welcoming sockets and the limits on how many such client sockets can be opened on a given machine.
