If the number of incoming clients requests exceeds the number of processes in a server class, the TP Monitor may dynamically start new ones and this is called Load balancing.
when to or more routes has same matrics to the same n/w load balancing is done i e packets send to destination using all paths which have same matrics .all routing protocols support 4 by default but upto 6 and ospf support multiple path load balancing
If router recive multiple path with the same administrative distance and cost to a destination in this case load-balancing will be accur. In the case of load-blancing router use the round dropping packets.
Distributing processing and communications activity evenly across a computer network so that no single device is overwhelmed. Load balancing is especially important for networks where it's difficult to predict the number of requests that will be issued to a server. Busy Web sites typically employ two or more Web servers in a load balancing scheme. If one server starts to get swamped requests are forwarded to another server with more capacity. Load balancing can also refer to the communications channels themselves
