[@dhivyapriya9803]

Sir, Awesome explanation once again!! I am following the book Data Communication and NEtworking by Forouzan . After seeing this video, I understood why routers deals with first 3 layers. No words to express about your explanation skill. May god bless you!

I searched many videos and finally found this one! Really well explained 👍

[@sabitkondakc9147]

Amazing Lectures, thanks to Neso Academy and compassionate people in the field I want to add more on Addressing : due to the fact that it's a connectionless service IP address is retrieved by DNS server, so that before making it to a router browser asks for the IP address via DNS server corresponding to the domain name.

[@abhishekmaurya9503]

But i have a question: How do routers/intermediary devices know whom to send packets that will lead to destination??? Which algorithm is used???

[@sabitkondakc9147]

@@abhishekmaurya9503 it's a really long story, I can't explain it from scratch but I may give you a pinch of it to make things a bit more clear. Your PC -> ISP -> Intermediary Devices -> Destination Server things get a lot complex in intermediary devices, protocols being used in between; QUIC(google invention alternative to TCP), UDP, FTP, SSL, TLS exc. the info passing through intermediary devices have a header and tail part, they are used for routing, there are bunch of algorithms being used for that , they simply guess where the info moves next according to header + IP + bandwidth + congestion other factors, it's a track between your public IP and the IP of website you request an answer. IP with subnet mask speaks for itself, frames can be routed according to subnet masks it's one part of whole story. Algorithm checks header+IP with subnet mask + exc. decides where to jump next. Think it as a graph data structure with nodes attained by specific IPs , it has a location protocol where a machine may guess last destination just by looking numbers I mentioned above. I hope this made it a bit more clear for you, take care of yourself.

[@AmiraUlmasova]

Bro just for the sake of clarification, process does not operate on a specific port, maybe protocol that is used by process usually operates on some specific port. If you start a process and process uses let's say tcp socket on some port let's say 4000 it doesn't mean that process assigned port 4000, it means that process uses socket that operates through port 4000 and you create a lot of sockets with different ports but that wouldn't mean that port is assigned to the process. Great explanation thanks for info😊

[@Damariobros]

Something that still confuses me is, how does Router 1 figure out that sending it down T/99 is the correct path, and not send it through X/44? Does it ask all the routers around it or something? What happens when there are more routers along the way than that, does it just tell them to pass the question down until an answer is gotten? How does that work?

[@AmiraUlmasova]

Router has Routing table that holds several entries and it starts looking the destination IP address from there. If there is no match, it sends packet to configured 0.0.0.0 router that is usually ISP router to figure out from there. If there is matching entry than router changes packet destination MAC address to the MAC address of the next hop router and sends it, if there are several matchings than in its Routing table router has specific field called Metric that represents the amount of hops till destination host and chooses the best route from there. There are much more to consider but this is simplified overall of the process

Sir, how would the incoming and the outgoing MAC address of the router may differ, or in the same way for any computer, does MAC address changes for incoming packets and outgoing packets? I've loved your explanation sir! Awesome❤

[@muhammadshahzaman7499]

basically mac address never chang. and if receiver becomes sender than only place of mac address change but mac address remain same.

sir just one confusion. when the packet is being transmitted from sender to receiver how does the router 1 knows that the packet should be transmitted in the direction of router 2? what if the router 2 has another connection to router 3 that leads to some other network? How does the router 1 decides whether to route the packet towards router 2 or router 3 in that case?

[@faressalem98]

Thanks for the video, why does each router have two IP and MAC addresses? Did you assume that it uses two different ports (LAN and Wireless for example) so each port has its own MAC address? if this is the case, does each port has its own IP address as well?

[@paranjay4776]

The short answer is: Yes. a router must have more than one interface (with an IP address per interface) , ex. LAN port has private ip address and WAN port has public ip address to send and receive packets

Very good.

[@DolaLado]

[@seanknight9808]

Yes, very good explanation. But I am confused about one thing-at about 8 min in the video, you said the first router as a MAC address at the first interface as well as an IP address. And it had another IP and MAC add at the exit interface. How can a router have two IP and MAC addresses?

If routers have n interfaces, n ip addresses and n Mac addresses
