UDP service. When an application uses a UDP socket, what transport services are provided to the application by UDP? Check all that apply.a$.$Real$-$time delivery. The service will guarantee that data will be delivered to the receiver within a specified time bound.b$.$Best effort service. The service will make a best effort to deliver data to the destination but makes no guarantees that any particular segment of data will actually get there.c$.$Congestion control. The service will control senders so that the senders do not collectively send more data than links in the network can handle.d$.$Throughput guarantee. The socket can be configured to provide a minimum throughput guarantee between sender and receiver.e$.$Loss$-$free data transfer. The service will reliably transfer all data to the receiver, recovering from packets dropped in the network due to router buffer overflow.f$.$Flow Control. The provided service will ensure that the sender does not send so fast as to overflow receiver buffers.
