The difference between flooding and broadcasting

Floods vs. broadcasting

Routing involves choosing the paths to use to send network traffic and sending packets along the selected subnet. Flooding and Broadcast are two routing algorithms used today in computer networks. Flooding sends all incoming packets through each outgoing edge. Broadcasting means that each device on the network will receive a packet.

What is a flood?

Flooding is a very simple routing algorithm that sends all incoming packets through each outgoing edge. Due to the operation of this routing algorithm, it is guaranteed that a packet will be delivered (if it can be delivered). But it is possible that several copies of the same package reach the destination. It is guaranteed that the flood algorithm finds and uses the shortest path for sending packets because it naturally uses all the paths in the network. There is no complexity in this routing algorithm; it's very easy to implement. Of course, the flood algorithm also has some drawbacks. As packets are sent by each outgoing link, bandwidth is obviously wasted. This means that a flood can actually degrade the reliability of a computer network. Unless necessary precautions such as number of hops or lifetime are taken, duplicate copies may circulate in the network without interruption. One of the possible precautions consists in asking the nodes to follow each packet which crosses it and to make sure that a packet crosses it only once. Another precaution is called selective flooding. During selective flooding, nodes can transmit packets only in the (approximately) correct direction. Usenet and p2p (peer-to-peer) systems use flooding. In addition, routing protocols such as OSPF, DVMRP and ad-hoc wireless networks use saturation.

What is broadcasting ??

Broadcasting is a method used in computer networks, which guarantees that each device on the network will receive a packet (broadcast). Since broadcasting can have a negative impact on performance, not all network technologies support it. X.25 and frame relay do not support broadcasting, and Internet broadcasting does not exist. It is mainly used in local networks (local area networks, mainly Ethernet and Token Ring), and is rarely used in large networks such as wide area networks (WAN). Even IPv6 (successor to IPv4) does not support broadcasting. IPv6 only supports multi-casting, which is similar to the one-to-many routing methodology that sends packets to all nodes that have joined a specific multicast group. Having all of them in the address of an Ethernet and IPv4 packet indicates that the packet will be broadcast. On the other hand, a special value in the IEEE 802.2 control field is used in Token Ring to indicate the broadcast. One of the drawbacks of broadcasting is that it can be used for denial of service attacks. For example, an attacker can send false ping requests using the source address of the victim computer. Then all nodes on this network will respond to this request from the victim computer, which will cause the entire network to fail. address of an Ethernet and IPv4 packet indicates that the packet will be broadcast.

What is the difference between flooding and broadcasting?

Sending a package to all hosts at the same time constitutes a broadcast. But flooding does not send packets simultaneously to all hosts. Packets would eventually reach all nodes on the network due to the flooding. Flooding can send the same packet multiple times over the same link, but broadcast sends a packet along a link at most once. Multiple copies of the same package can reach flooded nodes, but broadcasting does not pose this problem. Unlike flooding, broadcasting is done by specifying a special broadcast address on the packets.
