I am having problems understanding these inequalities with regard to TCP connection.

Receiving side

LastByteRcvd - NextByteRead <= MaxRcvBuffer
AdvertisedWindow = MaxRcvBuffer - (LastByteRcvd - NextByteRead)

Sending side

LastByteSent -LastByteAcked <= AdvertisedWindow
EffectiveWindow = AdvertisedWindow (LastByteSent - LastByteAcked)
LastByteWritten -LastByteAcked <= MaxSendBuffer
Block sender if (LastByteWritten -LastByteAcked) + y > MaxSendBuffer

Please either explain yourself or provide some useful link. Thank you.

Test Series
Even through B's browser has only viewed the first 80 bytes, its stack has received up to byte 600 in sequence from A. What will be the ACK and window in TCP header that B next sends to A? Note: If ACK is X and window in TCP header is Y then write answer as X+Y.
