Packet forwarding in simple terms is the forwarding of packets from one node to another from networking point of view. For example, a router or a switch. These networking devices make routing devices with the help of their routing tables and then select an outgoing interface. After that they make some changes in the packet header and push (forward) the packet to the selected interface.
In case you don't know the meaning of packet. Packer is the smallest unit of size in networking. Different networks has different packet size. For example, in ATM Networks the packet size is of 53 Bytes.

What companies offer call forwarding service?
There are several online companies that offer a call forwarding service. These companies include but are not limited to AQL, KBVO, Toil Free Forwarding and Voipfone.
What action will R2 take for a packet that is destined for 192.168.2.0 It will drop the packet?
It will forward the packet to R1
How can be determine if an IPv4 packet is carrying an ICMPv4 packet?
To determine if an IPv4 packet is carrying an ICMPv4 packet, you can examine the packet's Protocol field in the IPv4 header. This field is located at byte 9 of the header and has a value of 1 for ICMPv4 packets. If the Protocol field equals 1, then the payload of the IPv4 packet is an ICMPv4 packet. Additionally, you can further analyze the payload to confirm that it corresponds to an ICMPv4 message format.
What is packet data settings?
Yeah good question WHAT are Packet Data Settings? Hopefully you get a answer.
How do you use the word packet in a sentence?
As she put the packet of rice into the pot the enemy stopped her from enchanting a spell.
Which configuration file makes the changes persist across reboots to disable packet forwarding?
Network Configuration and Management is the configuration file that makes the changes persist across reboots to disable packet forwarding.
What portion of the IP packet does a router use to make forwarding decisions?
buffer
Which two of the following accurately describe the store-and-forward switching method?
Store-and-forward switching is a method used in networking where a switch receives the entire data packet before forwarding it to the appropriate destination. This approach allows the switch to check for errors and determine the best path for the packet, enhancing reliability and efficiency. However, it can introduce latency since the switch must wait to receive the complete packet before making forwarding decisions. Additionally, this method contrasts with cut-through switching, which begins forwarding the packet as soon as the destination address is read.
What is the name of a network layer packet?
A network layer packet is commonly referred to as a "packet" or specifically an "IP packet" when discussing Internet Protocol (IP). At this layer, data is encapsulated into packets for routing across different networks. The network layer is responsible for addressing and forwarding these packets to their destination.
When forwarding a packet which route will the packet select?
First, routing is the process a router performs when making forwarding decisions for each packet arriving at the gateway interface. To forward a packet to a destination network, the router requires a route to that network. If a route to a destination network does not exist on the router, the packet will be forwarded to the default gateway. Now, the destination network can be a number of routers or hops away from the default gateway. If the router has an entry for the network in its routing table, it would only indicate the next-hop router to which the packet is to be forwarded to and not the exact route to the final router. To sum it up, the routing process uses a routing table to map the destination address to the next hop and then forwards the packet to the next-hop address.
What address is used to send packets that are destined for an outside network?
Router uses IP address of destination node to do the direct packet switching..while bridge & switch uses the MAC address to packet forwarding.
Which type of network is most commonly used to implement a message forwarding system using dedicated point-to-point connections?
A packet-switched network
Why each input port in a high speed router stores a shadow copy of the forwarding table?
Each input port in a high-speed router stores a shadow copy of the forwarding table to ensure low-latency packet processing. This allows for quick lookups and decisions on packet forwarding without needing to access a centralized memory resource, which could introduce delays. By having local copies, the router can handle high traffic volumes efficiently while maintaining performance. Additionally, it enhances reliability, as it reduces the risk of bottlenecks or failures in the centralized forwarding table.

What is the difference between routing and forwarding?
routing refers to deciding the route of the packet from one system (a computer) to another system (a computer). It involves many intermediate routers and routing table knowledge.forwarding is a rather simple process of passing a packet from one port/interface to another port /interface. It generally involves one of the routers and routers forwarding table informationThat's what they called call forwarding service in telecommunication.
What is difference between packet switching frame switching and cell switching?
Packet Switching refers to the transfering of the packet from 1 node to the other. Where as Cell Switching ,means the switching of a cell from 1 network to the other. Pls note that Packet and Cells are 2 different forms. Packet itself has header and pay load and but Packets are variable in size unlike cells which are fix. When packets are switched, the Packet Switch is used and that Switch looks for the next hop in its routing or forwarding table but when a cell is switched, ATM switches are used and the cells actually carry the data and the header and travels from 1 ATM switch to the other. The ATM switches donot use the complex method as Packet Switches use.
How can a bridge know whether to forward frames?
How can a bridge know whether to forward frames? Answer: The bridge builds a list of MAC addresses on either side of the bridge. Therefore, it knows which packets should be forwarded to the other side and which should not. In the example of a packet that uses a MAC address not in its table it can err on the side of caution by forwarding the packet.
