Can multiple sockets use same port?
Multiple connections on the same server can share the same server-side IP/Port pair as long as they are associated with different client-side IP/Port pairs, and the server would be able to handle as many clients as available system resources allow it to.
Will the client use the same source port every time?
So, Yes, TCP the protocol can handle multiple connections from a single source IP address and source port.
Can a TCP socket have multiple connections?
And yes, it is possible for a client to have more than 64K concurrent connections total. From a single port, it can be connected to a potentially infinite number of servers (limited by available OS resources, available router ports, etc) as long as the server IP/port pairs are unique.
How many clients can connect to a single TCP port?
On the TCP level the tuple (source ip, source port, destination ip, destination port) must be unique for each simultaneous connection. That means a single client cannot open more than 65535 simultaneous connections to a single server.
Which protocols can use multiple TCP connections?
HTTP: Multiple TCP connections can be used at client and server end. FTP: For FTP also multiple connections can be used at the same time. TELENT: Only one TCP connection is allowed at a time. SMTP: SMTP also allows only one TCP connection at a time.
How do I accept multiple TCP connections?
Accepting Multiple Connections So for instance: public class InboundConnection { private Socket _socket; private ArraySegment _buffer; public InboundConnection(Socket clientSocket) { _socket = clientSocket; _buffer = new ArraySegment(new byte[4096], 0, 4096); StartReceive(); // Start the read async loop. }
How many TCP ports can be open at the same time?
Can a client have more than one TCP socket?
@FernandoGonzalezSanchez: A single client can have multiple TCP sockets bound to the same local IP/Port pair as long as they are connected to different remote IP/Port pairs. That is not specific to Windows, that is part of how TCP works in general.
@premktiw: Yes, multiple client sockets can be bound to the same local IP/port pair at the same time, if they are connected to different server IP/Port pairs so the tuples of local+remote pairs are unique. And yes, it is possible for a client to have more than 64K concurrent connections total.
Can a server have more than one port?
Multiple connections on the same server can share the same server-side IP/Port pair as long as they are associated with different client-side IP/Port pairs, and the server would be able to handle as many clients as available system resources allow it to.
When does a TCP connection become time _ wait?
During this 4 minutes, the TCP connection state will be TIME_WAIT state. In a situation where you suspect port exhaustion, an application or process will not be able to release all the ports that it has consumed and will remain in the TIME_WAIT state.
