2.1-4 TCP service. When an application uses a TCP socket, what transport services are provided to the application by TCP? Check all that apply. Select one or more: a. Real-time delivery. The service will guarantee that data will be delivered to the receiver within a specified time bound. b. Throughput guarantee. The socket can be configured to provide a minimum throughput guarantee between sender and receiver. 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. Flow Control. The provided service will ensure that the sender does not send so fast as to overflow receiver buffers. 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. 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.

of
2.1-4 TCP service. When an application uses a TCP socket, what
transport services are provided to the application by TCP? Check all
that apply.
Select one or more:
a. Real-time delivery. The service will guarantee that data will be delivered to the receiver within a
specified time bound.
b. Throughput guarantee. The socket can be configured to provide a minimum throughput
guarantee between sender and receiver,
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. Flow Control. The provided service will ensure that the sender does not send so fast as to
overflow receiver buffers.
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. 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.

Select one:
a.... are stored, each encoded at multiple rates (video quality). The client plays the video chunk-by-
chunk, with each chunk requested at encoding rate that fits the available bandwidth at the time.
b.... are downloaded just before their playout time. Chunking is used primarily because a viewer
may jump around (e.g., fast forward) in a video.
c.... are stored, each encoded at multiple rates (video quality). The client receives multiple video
chunks (encoded at different rates) and plays out the chunks that best fit the screen size.
Od.... allow premium users to avoid watching chunks that contain commercials.
e. are download smallest-chunk-first in order to maximize the number of chunks received.
