Can multiple threads write to the same socket?
No two threads can use the same Socket because of the Synchronize sections. So they’re never mutating it at the same time. However you’re not free of deadlocks, and you may very well end up with many threads waiting for the sync on the same Socket, when others are available.
Why does a server need to use a thread for each client?
We want our architecture to support multiple clients at the same time. For this reason, we must use threads on server side so that whenever a client request comes, a separate thread can be assigned for handling each request.
Are Linux sockets thread safe?
A single connection can only transfer data serially. If you want to allow a single client to make multiple concurrent requests, accept n connections from the same socket and associate a thread to every connection. It is safe to use different sockets concurrently.
How do you multiple clients connect to a single port?
Irrespective of stateful or stateless protocols, two clients can connect to same server port because for each client we can assign a different socket (as client IP will definitely differ). Same client can also have two sockets connecting to same server port – since such sockets differ by SRC-PORT .
Is socket send thread safe?
Description. According to the documentation, instances of Socket. Send are thread-safe. When running the same code on Linux, sporadically, the data that is received by the receiving party seems to be partially scrambled when Socket.
Are Java sockets thread safe?
Socket is not actually thread safe: Open the Socket source, and look at the (let say) connected member field and how it is used. You will see that is not volatile , read and updated without synchrinization. This indicates that Socket class is not designed to be used by multiple threads.
Socket sharing between processes in Windows Sockets is implemented as follows. Note however, that sockets may be shared among threads in a given process without using the WSPDuplicateSocket function, since a socket descriptor is valid in all of a process’ threads.
Is socket thread safe C#?
The Socket class is quoted by MSDN to be fully thread-safe.
How many clients can connect to a socket?
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. But a server can (theoretically) serve 65535 simultaneous connections per client.
How many connections can a port handle?
Ports are 16-bit numbers, therefore the maximum number of connections any given client can have to any given host port is 64K.
