Calculate the transmission delay for a packet of length $1,000$ bytes and transmission rate

$2$Mbps$?$

$**************************************************************************************************************************************$

Calculate the transmission delay between the two computers if the packet length is

Given a segment of network A$-$B with $2500$ km $($d$)$ of length and $4$ packets $($length of one

packet: L$=1250$ Bytes$)$; and channel speed $($transmission rate $=$ Bandwidth$)R=2M\frac{b}{s}$; the

signal pronagation anood $\frac{?}{cl}51ne\frac{m}{e}$

a$)$ The Packet transmission time

b$)$ The $($all packets$)$ Transmission Time

c$)$ The packet propagation delay

d$)$ The total packet delay

$**********************************************************************************************************************$

Consider the following segment of network, compute the total delay: dtotal if we have

L: packet length $($bits$)=2000$ kBytes, R: Link bandwidth $($bps$)=40M\frac{b}{s}$

D : length of physical link $(m)=250km,S$ : propagation speed in medium $\frac{m}{s}=1000k\frac{m}{s}$

dproc $+$ dqueue $=0\mathrm{.}2sec$

Consider sending a packet between two hosts, compute the total delay if we have packet length $=$

$1000$ kBytes $,$ Link bandwidth $=1M\frac{b}{s},$ length of physical link $4000$ km $,$ and propagation speed

in medium $=1000k\frac{m}{s}.$ Note that: $d_{\text{p}\text{r}\text{o}\text{c}}=d_{\text{q}\text{u}\text{e}\text{u}\text{e}}=0\mathrm{.}5$sWe are sending a $30$ Mbit file from a source host to a destination host in one$-$hop. The link between

source and destination have a transmission rate of $10$ Mbps and the queuing time for the packet is

$1\mathrm{.}5$ sec $.$ Assume that the propagation speed is $2**{10}^7$ meters $\frac{?}{sec},$ the distance between source and

destination is $10,000km,$ and the processing time is twice the queuing time $($dproc $=2$ dqueue$).$

Calculate the following:

a$)$ Initially suppose there is only one link between source and destination. Also suppose that

the entire file is sent as one packet. What is the transmission delay?

b$)$ What is the total propagation delay?

c$)$ What is the total delay?
