Framing in Computer Networks Video Lecture - Computer Science Engineering (CSE)

hello guys this Abhishek Singh from
Curtin University of Science and
Technology today we'll be talking to you
about framing framing means path in the
pot data with certain information
representing off this blue area is that
at all that adding certain formation
like Adam Taylor and flax so this whole
thing is called in this process of
adding data information to the data this
table flag indicates the starting and
ending of the tree here flag tells the
starting and ending of fig header tells
the source for destination address as
well as the control information after
tells from goggles and a frame isn't
where it is to business Taylor tells the
election law detection code that means
varied and as a poor tells whether the
data is correctly to see if it is heopop
flag as I told it tells the starting and
ending of the thing next more to buy it
process bit stuff Nicholas we see there
are data stored in fights as he that is
stored in bytes this that is total bits
is machine language that is a difference
it in white will be toggled at put bulbs
thanks we want to byte stuffing unless
we see byte stuffing is a process of
adding extra byte whether there is an
escape or a flag character in the data
and as you see there is flag and escape
character so what we do is add an extra
byte say escape
so when the contour moves from here it
finds escapes bit and it escapes an
expert means from here it goes directly
to here then again it goes from here
product to your soul for that escape bit
decided this was sending board is really
single part that is sent and that is
received in the same fashion
makes me want to bite stuff to suppose
is the padding next traffic to ensure
flag slickest is not repeat here you see
zero one one one six one one zero so in
order not to repeat the sequence you add
an extra bit save zero bit save the case
of escaping byte stuffing we added an
extra bit and the data is received in
the same fashion
next flow navigable flow control means
it is a set of procedure that tells us
and then how much of data can be sent
before waiting for the Polish mint that
means see the sends an acknowledgment to
the sender it is a it has received the
data so flow control self how much or
how many number of frames can be sent to
the receiver before sending the next
enter next I will control includes error
detection and correction it allows
receiver to send information of the lost
window big hit teams here Kimmie's auto
repeat request it does how many times it
has to repeat sending people's famous
lost or
Fame flourish - post for acknowledgment
is delay in returns how when schematize
attested it's going more particles not
having portables for are two types one
is noiseless channel model is my second
channel is divided into two simplest and
stop hundred the speed will be talking
about simplest next feeding silly dolly
work nice and we pressed all the buttons
and the noiseless channel we take two
assumptions error free and there is no
need of error control from this the
sender sends data for Network layer data
link layer blend of is good lab then we
see the data sent the physical layer
receives it then sends true data link
layer the sends to network layer and the
same that is received from sender to
receiver the only thing is that this
like knowledge would so that our chances
for ever since it is voiceless channel
we have assumed that there will be no
where the certain sets of protocols as
you can see this is a simple program
sender and receiver here we see the
sender since the train the receiver
receives it then it take the smaller
that way then it receives it triggers
one other thing with the season only
disadvantages if the frame is lost
somewhere over here in this part reach
that frame is lost forever
nicely seen next video till then stay

thank you
