Assignment
 Suppose we proposed a new protocol called EP (Emerging Protocol), just like an IP.  The protocol has the following attributes.

1
 
 
Version (i.e. 4 bits)
FU=( 8bit)  
ToS=(4 bit)
Source Address=(16bit)
Destination address=(16 bit)
Total Header size is= 48 bit
You all are requested to think about it how is this scheme works? If got no answer let me know I will explain it to you in detail.
 
 
·         Version (i.e. 4 bits) Given 
·         FU=( 8bit) mentioned clearly that 8 bits reserved for future use. 
·         ToS=(4 bit)
Because minimum 4 bit required to represent 16 different numbers from 0 to 15. class 0 = 0000 and class 10=1010 and class 14= 1110 . In this way we need 4 bits to represent 16 different classes. 
·         Source Address=(16bit) As mentioned total number of hosts will be the 65536 so we need 16 bits to represent 65536 different source addresses. 
·         Destination address=(16 bit) The destination address will also be equal to source address so it will also consist of 16 bit to represent 65536 different users of network. 


 
 Good Luck
