Suppose, In Selective Repeat Protocol 10 packets are sent and every 4th packet is lost. 

Then, 1 2 3 4 4 5 6 7 7 8 9 10 10  {bold denote lost packets, so retransmitted!}

 Is this the right order of transmission of packet no.??

Order may differ..Lost packet will be resent after its time out at sender side

But it is sure that only Lost packet will be retransmitted!

The lost packets will be retransmitted after getting the respective ACKs. So the correct order should be 123456789104710 right ?
