	English Consider a reliable connection-oriented transport protocol that provides the bytestream service. In this transport protocol, the sequence number that is placed inside each DATA segment reflects the position of the bytes in the bytestream. Considering the connection shown below, provide the DATA segments that are sent by `Host A` in response to the `DATA.request`, assuming that one segment is sent for each `DATA.request`. 424/10000 · 424

	English Same question as above, but consider now that the transport protocol tries to send large DATA segments whenever possible. For this exercise, we consider that a DATA segment can contain up to 8 bytes of data in the payload. Do not forget to show the acknowledgments in your answer. 280/10000 · 280

	English Consider a transport protocol that provides a reliable connection-oriented bytestream service. You observe the segments sent by a host that uses this protocol. Does the time-sequence diagram below reflects a valid implementation of this protocol ? Justify your answer. 268/10000 · 268

	English In the above example, the two `DATA` segments were lost before arriving at the destination. Discuss the following scenario and explain how the receiver should react to the reception of the last `DATA` segment. 209/10000 · 209

	English A network layer service guarantees that a packet will never live during more than 100 seconds inside the network. Consider a reliable connection-oriented transport protocol that places a 32 bits sequence number inside each segment. What is the maximum rate (in segments per second) at which is should sent data segments to prevent having two segments with the same sequence number inside the network ? 401/10000 · 401

	English Amazon provides the `S3 storage service <https://s3.amazonaws.com/>`_ where companies and researchers can store lots of information and perform computations on the stored information. Amazon allows users to send files through the Internet, but also by sending hard-disks. Assume that a 1 Terabyte hard-disk can be delivered within 24 hours to Amazon by courier service. What is the minimum bandwidth required to match the bandwidth of this courier service ? 457/10000 · 457

	English Some transport protocols use 32 bits sequence numbers while others use 64 bits sequence number. What are the advantages and drawbacks of each approach ? 152/10000 · 152

	English Consider a transport protocol that provides the bytestream service and uses 32 bits sequence number to represent the position of the first byte of the payload of DATA segments in the bytestream. How would you modify this protocol so that it can provide a message-mode service ? Consider first short messages that always fit inside a single segment. In a second step, discuss how you could support messages of unlimited size. 424/10000 · 424
