Detailed Description

Packet Buffering Case B.

--— = old packets +++++ = new packets

CASE B: startSeq > endSeq

  • + + initial buffer state: 256 64000 16

0 4095 |++++++|-------------—|++++++| ^ ^ | endSeq = 10 | startSeq

first received packet's sequence control = 240 (seqNum = 15, fragNum = 0) - second received packet's sequence control = 241 (seqNum = 15, fragNum = 1) - third received packet's sequence control = 64800 (seqNum = 4050, fragNum = 0) + 240 is an old packet should be inserted at the buffer's begin. 241 is an old packet: second segment of the above packet. 4050 is a new packet: it should be inserted between 64000 and 16.

expected buffer state: 240 241 256 64000 64800 16
