Which osi layer facilitates the routing of packets over an IP network?
Network
Which network layer protocol is responsible for routing packets on the network?
The network layer is the layer that is responsible for routing packets on the network. This is the layer in which Internet protocol operates. In the seven layer OSI model, the network layer is the third layer from the bottom.
Where is the routing?
It is the process of forwarding packets in a network so that it reaches its intended destinations. To perform routing there are numbers of routing algorithm .

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.
Which layer of the OSI can route packets to eliminate problems like network congestion?
If you are talking strictly about routing, then layer 3 (the Network layer). There are some routing protocols, usually known as link-state routing protocols that are aware of network congestion problems and can re-route as necessary. Network congestion is not restricted to routing alone, however. At layer 4 (Transport Layer) there is a facility known as flow control, which can pause a sending network if the receiving network is too busy to accommodate all the packets.
What happens when the packets are too big?
When packets are too big for a network to handle, they may be fragmented into smaller packets for transmission. If fragmentation is not possible, the packets may be dropped, leading to data loss and requiring retransmission. This can result in increased latency and reduced overall network performance. Additionally, oversized packets can cause congestion and inefficiencies in network routing and processing.
What is packet routing?
Packet routing is the process of selecting paths in a network along which to send network packets. Routers use routing tables and protocols to determine the best path for data packets to travel from the source to the destination across interconnected networks. This involves analyzing various factors such as network congestion, path reliability, and the shortest distance. Effective packet routing ensures efficient data transmission and minimizes latency and packet loss.
How many types of routing?
There are primarily three types of routing: static routing, dynamic routing, and default routing. Static routing involves manually setting routes in the routing table, while dynamic routing uses protocols (like RIP, OSPF, or BGP) to automatically adjust routes based on network changes. Default routing is a simplified method that directs packets to a predefined route when no specific route is available. Each type serves different network needs and complexities.
What are the types of protocols?
routing protocol: helps to find the best path to transfer the packets from one network to diffrent network example: rip: routing information protocol igrp, ospf...... routed protocol: helps to carry the packets to the destination. example: smtp : transfer the mails ftp : transfer the files.
What is the purpose of a simple routing table in a computer network?
A simple routing table in a computer network is used to determine the best path for data packets to travel from one network device to another. It helps the network devices efficiently route and deliver data to their intended destinations.
What is the advantage of dynamic routing?
The router needs a routing table, to know where to send IP packets. The purpose of dynamic routing is to update the routing tables automatically. This means you need much less configuration, and the network dynamically adjusts to topology changes (for example, a router is added, or a cable has a bad connection).
