In the last lecture, we talked about the remote access services and remote Nexstar protocol, it does
get done with the other remaining or access protocols which help us.
The first one is the point to point protocol.
The point-to-point protocol is a layer to protocol.
I forgot to display that.
I'm sorry.
So, yeah, point to point protocol is layer to protocol that provides authentication, encryption and
competition services to clients logging in remotely.
Now Internet service providers use up a lot to authenticate clients dialing in with a dial up modem
or DSL or cable modem.
Many network servers that provide remote access services such as RSS, can also use PGP as an authentication
protocol.
Now the next protocol is I'm sorry we have done this P2P point protocol PGP.
Now, the next protocol that we're going to see is this one they point to point protocol over Ethernet.
Now, Point-to-point protocol over Ethernet is an extension of PGP.
Its purpose is to encapsulate the frames within the Ethernet frames, the need for people.
E was born out of the need to deal with the massive increase in high speed Internet connections.
Now service providers offering customers high speed access using asymmetric digital subscriber line
that is DSL or cable modems needed a Ofay to offer authentication and encryption services of point-to-point
protocol.
Remote authentication diron user service radius, which we are going to see in upcoming lecture's is
something I'll get into it a little later in this section is a radius is used to manage PBB or reconnections.
Make sure you remember the sentence.
The next is independent computing architecture.
I see now independent computing architecture is a protocol which was designed by Citrix Systems to provide
communication between these servers and the clients.
The most common application that uses I.C.E. is systems districts.
Winfree, which administers can use to set up Windows application on a Windows based server and then
allow the clients with virtually any operating system to access those applications.
Client computers running Linux, Unix or Marquises can access Windows based applications using the ICC
protocol.
Now, connections like these, which I just told you, tend to be slow because of the huge amount of
translation that is required to enable the client and the server to communicate with each other properly.
The next protocol is secure socket cell.
That is SSX.
You have heard this protocol when it comes to ethical hacking or, you know, networking earlier.
Secure Cell is a network protocol that is designed as an alternative to command based utilities such
as Tenet.
Now, Telnet is a protocol that transmits requests and responses in clear text and hence provides no
security, whereas the search creates a secure channel between the devices and provides confidentiality
and integrity of the data transmission.
As the search uses public key cryptography to authenticate the remote computer and allow the remote
computer to authenticate the user if necessary.
Now, this publicly is placed on any computer that must allow access to the owner of the matching private
key, which is kept secret, obviously, and the private key is never transferred to the network during
authentication.
So just make sure that Secich is an alternative to Tenet and it is more secure.
The next and the last remote access service protocol that we are going to see is, Vincey, that is
virtual network computing, virtual network computing.
The ANC is a remote desktop sharing system that uses the remote frame buffer protocol.
Now, Vincey includes Yansi Server, that is a software which runs on the machine sharing its screen.
Then the client, that is a machine that receives the shared screen and the B and C protocol, which
is a type of Pardeep remote or Ixtapa protocol.
Now, one big difference between VMC and our DP is that VSC sends raw pixel data, which does make it
work on any desktop type, whereas RTP sends graphic primitives on higher level commands for the screen
transfer process.
Well, this was it for the other protocols we have seen or as we have seen already, B, we have seen
PBB Point-to-point over Ethernet.
I see a secure shell and virtual network computing for your exam or any network based exam or clearing
interviews.
You just have to remember these protocols and you will come out with flying colors.
That is it.
I will see you in the next lecture.
