Answer;
-Northbound APIs
Communication between SDN controllers and routers is governed by Northbound APIs.
Explanation;
-The northbound application programming interface (API) on an SDN controller enables applications and orchestration systems to program the network and request services from it.
-Northbound APIs can enable network functions like path computation, loop avoidance, routing and security. The northbound APIs can also used to facilitate innovation and enable efficient orchestration and automation of the network to align with the needs of different applications via SDN network programmability.
Notice that independently, the prey population goes up, if the predator's population is low. One interpretation is that there are not enough predators to really make a dent in the prey's population. But as the prey's population increases, they become easier targets for the predators since there are so many. As predators feed on prey, the predator's population increases (more food, can sustain a bigger population) and the prey's population decreases. As less and less prey are available to hunt, the predator's population also decreases.
Note that it need not be this cyclical, the trend can go to an equilibrium point where the populations do not fluctuate all that much.
the predator eats the prey limiting them to not overly grow. And the prey do not overly grow limiting the predators population to not overly grow as well. hope that helps
It has been known that the greatest cause of muscle atrophy is lack of physical activity, that contributes to your muscle to waste away. This can possibly happen when you accidentally injured yourself or might have a certain disease that makes it for you difficult or to move your body as well.
