Improving Network Utilization Using Dynamic Allocation Adjustment Algorithm
Manisha Sunil Bhende, D. B. Gothwal, Nitin Patil · 2009
When you design networks that transport voice over packet, frame, or cell infrastructures, it is important to understand and account for the delay components in the network. If you account correctly for all potential delays, it ensures that overall network performance is acceptable. Delay guarantees are critical to real-time applications. To ensure the end-to-end delay guarantee of a flow, the previous approaches usually statically divide the end-to-end delay requirement into per-hop delay requirements. However, such static resource allocations may cause unbalanced usage in a network, limit the total number of sessions that can be accommodated, and result in low network utilization. To address this issue, we propose a dynamic allocation adjustment (DAA) approach to evenly spread traffic over flow paths and related links, and improve the system utilization.It is useful for unicast and multicast or symmetric and asymmetric Topology DAA is able to significantly increase the total number of flows admitted; it reduces the average link reservations, decreases the total resource usage per flow, and balances link loads.
