Difference Between Flooding and Broadcasting

Routing is the process of choosing the paths to be used to send network traffic and sending packets along the selected sub-network. Flooding and broadcast are two routing algorithms used in computer networks today. In case of Flooding all incoming packets are sent for each outgoing edge. By transmitting means every device in the network receives a packet.

What is Flooding?

Flooding is an algorithm which sends routing to all incoming packets for each outgoing edge. Because of how this routing algorithm works, a packet is delivered with surety (if it can be delivered). But multiple copies  of the same packet may also reach the destination. It agrees that the flooding of the algorithm finds and uses the shortest path to send packets because it uses naturally every path in the network. There is no complexity in routing algorithm; it is very easy to perform. Obviously, there are few disadvantages of the algorithm also flooding. Because of the fact that packets are sent by means of an outgoing link, the frequency band is wasted. As a result an overflow can really degrade the integrity of a computer network. Unless precautions such as hop count or time to live is taken, copies can run double in the network constantly. One precaution must ask the nodes to track each package through the package and ensure that this happens only once. Another precaution is called a selective flooding. The nodes are able to send packets in the correct direction only. Usenet and P2P (peer-to-peer) flooding systems are used. In addition, routing protocols such as OSPF, DVMRP and ad hoc wireless networks use flooding.

What is broadcasting?

The broadcasting is a method used in computer networking, which ensures that each device in the network receive a (broadcasted) packet. Broadcasting can have an impact on the performance in a negative way, not every network technology supports the broadcasting. The relay and X.25 framing does not support broadcasting and there is no such thing as internet wide   of the entire Internet. It is primarily used in LANs (Local Area Networks, especially Ethernet and token ring) and is rarely used in larger networks such as WANs (wide area networks). Even IPv6 (the successor to IPv4) does not support broadcasting. IPv6 only offers supports  to Multicasting, which is similar ‘to one to many’ routing methodology that sends packets to all the nodes that have joined a specific multicast group. Possession of all the address of an Ethernet packet in both IPv4 indicates that the packet will be transmitted. In addition, a special value in IEEE 802.2 control field is used in the ring to indicate the symbolic issue. A disadvantage of the show has is that it can be used to DoS (Denial of Service) attacks. For example, an attacker can send requests tingling false using the address of the victim’s computer as the source address. Then all the nodes in the network will meet the request of the victim’s computer because of a failure of the entire network.

What is the difference between the Flooding and Broadcasting?

Sending a packet to all hosts concurrently is broadcasting. But the flooding does not send packets to all hosts concurrently. The packets will lastly reach all nodes in the network due to flooding. Flooding can send the same packet along the same link multiple times, but the program sends a packet along a link at most once. Several copies of the same package can reach nodes in the flooding, whilst the matter does not cause this problem. Unlike broadcasting, the show is done by specifying a special address on the packets.
