Latency is the time it takes a data packet to travel from point-to-point on the network. Each step your traffic takes through the network will add to its latency. Latency higher than 150 milliseconds (ms) will cause unnatural delays in an audio conversation. On a video call, high latency could create a disconnect between the audio and the video
2019-11-18 · Layer 3 is the IP layer, which carries information about where in the whole network the packet is from and to, not just the current hop. The transmission would go like this: Machine A wants to send a packet to Machine B. Machine A knows Machine B's IP address, so it places that in the layer 3 packet. Network Basics: Following a Packet through the Layers 2020-7-8 · In a computer network, a packet of information flows through seven layers as it travels from one computer to another. The data begins its journey when an end-user application sends data to another network computer. The data enters the network through an Application layer interface, such as SMB. The data then works its way down […] routing - How does a packet travel across multiple routers 2020-5-22 · My understanding of how a TCP/UDP packet would be processed in the example above: Host 2's default gateway is set to 172.16.1.1 (by default somehow?), and it sends a frame to Router 2's eth1 MAC address (obtained through ARP?). The enclosed packet has source 172.16.1.100:portA and destination 192.168.1.100:portX. What is network packet? - Definition from WhatIs.com A packet is the unit of data that is routed between an origin and a destination on the Internet or any other packet-switched network. Network packets are small (around 1.5 KBS for Ethernet packets and 64 KBS for IP packet payloads) amounts of data passed over TCP/IP networks. As an example, e-mails and web pages will make use of network packets to send information back and forth to the user
There are simple rules for a packet flow in a network: If the destination host is present in the same network of the source host then the packet will be delivered directly to the destination host using MAC address. Within a network, the packet will be delivered on the basis of MAC address. MAC address never crosses its broadcast domain.

Then the original packet comes to the VPN-Gateway (probably his router), which encapsulates this original packet into for instance an IPv4-packet where the destination address is the VPN-Gateway (network B) and source address is its own. That way, the packet can travel over the internet to the other VPN-Gateway (network B).

Optional activities are designed to enhance understanding and/or to provide additional practice. How IP Packets are Routed on a Local Area Network If you read through this routing table, you will notice that if a packet's network destination address is anything other than an address defined in the 192.168.0.0/24 subnet, it will be sent to the gateway (line 1) which is 192.168.0.254 and will leave out of the interface with an IP of 192.168.0.1.
