Why can't we use dynamic routing algorithm?

What is hot potato routing?

A form of routing in which the nodes of a network have no buffer to store packets in before they are moved on to their final predetermined destination. In normal routing situations, when multiple packets contend for a single outgoing channel, packets that are not buffered are dropped to avoid congestion. But in hot potato routing, each packet that is routed is constantly transferred until it reaches its final destination because the individual communication links can not support more than one packet at a time. The packet is bounced around like a "hot potato," sometimes moving further away from its destination because it has to keep moving through the network. This technique allows multiple packets to reach their destinations without being dropped. This is in contrast to "store and forward" routing where the network allows temporary storage at intermediate locations. Hot potato routing has applications in optical networks where messages made from light can not be stored in any medium.

Deflection routing, also known as hot potato routing, is a routing strategy for networks based on packet switching which can reduce the need of buffering packets. Every packet has preferred outputs along which it wants to leave the router, and when possible a packet is sent along one of these outputs. However, two or more packets may want to leave along the same output (which is referred to as a contention among packets) , and then only one of the packets may be sent along the link, while the others are sent along available outputs, even though the other links are not preferred by the packets (because, for instance, those links do not yield shortest paths).

Depending on the rate of incoming packets and the capacity of the outgoing links, deflection routing can work without any packet buffering. Of course, it is always possible to simply drop packets in a network with a best effort delivery strategy.

What is delta routing?

Bhumi said: (Sep 15, 2012)  
The Delta routing protocol is based on the idea that when congestion is detected in PPN ,packets should be forwarded through VPN tunel around congestion rather than simply dropped. Diverting traffic in this way leads to lower packet drop rates.

What is flooding routing?

Puja Havile said: (Aug 25, 2014)  
Flooding routing is based on the idea that when packet arrives to the router, it simply creates multiple copies of that packet to send to a multiple links connected to it. Each router does the same, as a result there are so many copies of the same packet on the network. This creates Flood like situation, is nothing but flooding routing.

Potato Routing is also called as Deflection Routing. Hot Potato routing is the routing technique enabling packet routing without storing them in buffers.

The Hot Potato routing technique continuously transfers data until the packet reaches the destination without the packets having to wait or stored in the buffer.

Hot-potato routing is the practice of passing traffic off to another autonomous system as quickly as possible, thus using their network for wide-area transit.
