Resource Allocation Algorithms

Definition

Resource allocation algorithms are computational methods designed to efficiently distribute limited resources among various tasks or processes in a network. These algorithms are crucial in optimizing the performance of networks by ensuring that bandwidth, processing power, and storage are allocated in a way that meets the demands of applications while minimizing waste. In the context of network management and operations, they enable dynamic and intelligent distribution of resources, which enhances overall network efficiency and responsiveness.
