Network capacity, a key performance index, varies with routing strategies and topology. Homogeneous networks and traffic-aware routing significantly enhance maximum traffic flow capacity.
Area of Science:
- Computer Science
- Network Engineering
- Telecommunications
Background:
- Network capacity is a critical metric for evaluating communication system performance.
- Understanding how network structure and routing influence capacity is essential.
Purpose of the Study:
- To investigate the impact of different routing strategies on network capacity across various topologies.
- To quantify the relationship between network homogeneity and its traffic flow capacity.
Main Methods:
- Simulated network performance under distinct routing protocols.
- Analyzed capacity variations across three different network topologies.
- Evaluated the effect of a novel traffic-aware routing strategy.
Main Results:
- Network capacity is significantly influenced by the underlying network topology.
- Increased network homogeneity correlates with higher traffic flow capacity.
- A traffic-aware routing strategy substantially enhances network capacity.
Conclusions:
- Network topology and routing protocols are key determinants of network capacity.
- Optimizing network structure towards homogeneity and employing traffic-aware routing are effective strategies for capacity enhancement.
