Abstract:

In order to solve the problem of bandwidth allocation on a single channel and load balancing in a channel group in HFC access networks, we propose a bandwidth allocation scheme based on multi-bid auction. Service agents submit their bids to the edge resource manager who runs the auction. The bandwidth is allocated by the improved multi-bid auction scheme. Multimedia services' QoS is guaranteed by admission control and bandwidth reservation. Load balancing can be achieved by service agents' user assignment scheme. Theoretical analysis and experimental results demonstrate that the proposed approach allocates bandwidth efficiently with little communication overhead and low time complexity. It also balances the load in a channel group.

Key words: HFC access networks, bandwidth allocation, multi-bid auction, load balancing
