WebApr 21, 2013 · Network layer protocol supervises the transmission of packets from a source machine to a destination. Data is broken down into packets, or datagrams, up to 64 kb long before it is transmitted, with a stamp of destination IP address, and forwarded to the network gateway. A gateway can be router to interconnect networks. Share Improve this … WebIP will then look at the packet header to see the protocol number, and it will send the packet payload to the correct transport protocol (TCP, UDP, etc.). The transport protocol will then send the datagram payload to the application registered to it (TCP and UDP use ports for this, other transport protocols may do something else).

Routing algorithms within each node establish a route to the next node by the use of metrics such as hop count, delay, bandwidth, etc. There is no formal call setup and this procedure resembles a postal system. shark tank curtain rod holder

"WebFeb 5, 2024 · 9. it seems that routers decapsulate the frame on arrival, and encapsulate the packet in a frame in order to send it. Yes. A router must strip off the layer-2 frame in order to get to the layer-3 packet. The router then routes the packet to the next interface toward the destination, based on the layer-3 destination address. " - How do packets travel in datagram networks
