What is the minimum number of bits the sequence numbers should be?
But to the question asked, the answer is 6. In general, N bits (binary digits) are required to represent unique integer values.
What is the fewest number of bits needed in the sequence number field of the packet to correctly implement the sliding window protocol?
Minimum number of bits required in sequence number field = 7.
What is the minimum window size where the sequence number is an n bit binary value?
If the sequence number of the frames is an n-bit field, then the range of sequence numbers that can be assigned is 0 to 2๐โ1. Consequently, the size of the sending window is 2๐โ1. Thus in order to accommodate a sending window size of 2๐โ1, a n-bit sequence number is chosen.
How many bits are needed to represent Stopand Wait’s unique sequence numbers?
one bit
For Stop-and-Wait, we only need 2 unique sequence numbers since there can be only one โoutstandingโ segment at any given point in time. Thus, in order to minimize overhead, one can use sequence numbers โ0โ and โ1โ, and thus only one bit is needed to represent sequence numbers.
How many bits are sequence numbers?
32 bits
The sequence number field is 32 bits. Naively, this means each byte stream can be up to 232 bytes, or 4.3 gigabytes, long. Does this mean you can’t use a plain TCP connection to download a file larger than 4.3 gigabytes? No: when the sequence number 232 is reached, the sequence number wraps around to zero again!
How many bits are there for the Acknowledgement number?
32-bit
The sequence and acknowledgment number fields are both 32-bit fields that hold TCP sequence numbers. The sequence number field contains the sequence number of the first byte of data in the TCP segment.
How many bits are there in sequence number?
Sequence Numbers โ The 32-bit sequence number field defines the number assigned to the first byte of data contained in this segment.
How do I know if I have a sliding window problem?
Top Problems on Sliding Window Technique
- Find the longest substring of a given string containing k distinct characters.
- Find all substrings of a string that are permutation of a given string.
- Longest substring of given string containing distinct characters.
How do you calculate maximum window size?
The window scale value can be set from 0 (no shift) to 14. To calculate the true window size, multiply the window size by 2^S where S is the scale value. For Example: If the window size is 65,535 bytes with a window scale factor of 3.
What is the minimum window size required for Go Back N ARQ and why?
Go-Back-N protocol, also called Go-Back-N Automatic Repeat reQuest, is a data link layer protocol that uses a sliding window method for reliable and sequential delivery of data frames. It is a case of sliding window protocol having to send window size of N and receiving window size of 1.
Why the size of sender window must be less than 2m in Go Back N ARQ?
8. In Go-back-N ARQ, the size of the sender window must be less than 2m, where m is the number of bits used for the representation of sequence numbers. A Selective Repeat ARQ is using 7 bits to represent the sequence numbers.
How many bits are needed for sequence numbers in a stop and wait protocol?
Working of Stop and Wait for ARQ: There is only a one-bit sequence number that implies that both sender and receiver have a buffer for one frame or packet only.
