Apr 10, 2018 · This is at the application layer, similar to HTTP. Your XML is sent over a tcp or udp socket which operates at layer 4. TCP/UDP will use IP (layer 3) to transfer data between hosts. Your computer will use Ethernet (layer 2) to talk across a local network. The network card will use a cable (layer 1) to get data from one device to another.

Mar 18, 2010 · Adding to that a layer 2 switch normally does hardware routing. It basically sets up a hardware switch module based on bytes in the ethernet packet for "switching the packets according to route". So it is / can be a LOT more efficient than a …

Jan 13, 2010 · End-to-end is required because not ALL network layers are particularly reliable, and only the end systems know how much reliability is really required. Also, if there is more than one lossy link, only the end systems know which packets really need retransmitted (or corrected for) and end-to-end reliability therefore minimises the extra work to ...

Mar 6, 2015 · Routers: (Layer 3/IP)- It is an electronic device that connects atleast two networks and exchanges packets among them according to the information provided in the headers of these packets and the routing tables.They are designed to join together multiple local area networks (LANs) with a wide area network (WAN).They are smarter than Hub or ...

Aug 25, 2021 · A layer 3 network encompasses the IP configurations as well as the MAC addressing for each node on the network. They often can handle inter-domain routing between vlans and broadcast domains. The main difference between a layer 2 switch and a layer 3 switch is the routing function.

Jan 23, 2015 · So yes, they are talking about limiting the size of your layer 2 network. Remember that broadcasts get sent to everyone on your layer 2 network, so segmenting it with routers or layer 3 capable switches helps keep things flowing. VLANs are one way to achieve this. Also, STP can cause issues when the layer 2 domain is too big.

A network device communicates with another network device. Layer 3 address used for Unicast is IPv4 Class A, Class B, Class C addresses. Layer 2 address is a unicast MAC address. Example: Browse a website, Download file using FTP, Connect to another device using SSH (Secure Shell) etc. 2) IPv4 Multicast One-to-many type of communication. A ...

May 14, 2009 · Spanning tree protocol is a link layer network protocol that ensures a loop-free topology for any bridged LAN. It is based on an algorithm invented by Radia Perlman while working for Digital Equipment Corporation. 1 [2] In the OSI model for computer networking, STP falls under the OSI layer-2.

Data link layer may provide flow control "on the wire". Network layer provides flow control between routers by ICMP. The end terminals usually do not use the network layer barely. IP does not provide flow control. Transport layer, more specifically TCP provides flow control by a backtracking algorithm while UDP does not.
