Note that $$'x?'$$ means $$0$$ or $$1$$ occurrence of the symbol $$x.$$ Note also that the analyzer outputs the token that matches the longest possible prefix.
If the string $$bbaacabc$$ is processed by the analyzer, which one of the following is the sequence of tokens it outputs?
Which one of the following is correct for the given parse tree?
Field | Length in bits |
---|---|
P. UDP Header’s Port Number | I. 48 |
Q. Ethernet MAC Address | II. 8 |
R. IPv6 Next Header | III. 32 |
S. TCP Header’s Sequence Number | IV. 16 |
$$(i)$$ $$\,\,\,\,\,\,\,\,\,\,\,$$ The $$cwnd$$ increases by $$2$$ $$MSS$$ on every successful acknowledgment.
$$(ii)$$ $$\,\,\,\,\,\,\,\,\,$$ The $$cwnd$$ approximately doubles on every successful acknowledgement.
$$(iii)$$ $$\,\,\,\,\,\,\,$$ The $$cwnd$$ increases by $$1$$ $$MSS$$ every round trip time.
$$(iv)$$ $$\,\,\,\,\,\,\,\,\,$$ The $$cwnd$$ approximately doubles every round trip time.
