GATE CSE 2017 Set 2 | Question: 13
A circular queue has been implemented using a singly linked list where each node consists of a value and a single pointer pointing to the next node. We maintain exactly two external pointers FRONT and REAR pointing to the front node and the rear node of the queue, respectively ... to the front node. (I) only. (II) only. Both (I) and (II). Neither (I) nor (II).

Transport Layer
In Transport layer either in TCP header or UDP header in checksum field we calculate checksum for Pseudo header of IP + header of TCP/UDP + data of TCP/UDP. Transport layer should fill checksum field in header before the Segment pass to Network layer. Here my doubt is how TL knows the IP header which is going to create in next step NL ?

TCP slow start
Suppose TCP’s additive increase and multiplicative decrease algorithm is used as a congestion control algorithm. The slow start phase begins with $4$ MSS and threshold at start of first transmission is $16$ MSS. Assume that a time-out occurs during $6$th transmission, what will be the congestion window at $10$th transmission.
