Abstract:
Recently, Broadband Convergence Network (BcN), a Korean version of Next Generation Network (NGN), was introduced to guarantee pre-defined QoS for high speed multimedia service. The BcN is considering charging users for premium services. For the BcN to be successfully diffused, however, a practical traffic engineering (TE) tool is required because the BcN is composed of many kinds of subnetworks, and real time feedback (traffic control) would be mandatory for the premium service. In the paper, a new TE scheme for BcN, Rule Based Capture(RBC)/User Satisfaction Parameter(USP), is proposed to resolve the latent problems of the BcN TE. The USP is designed to be admitted by many BcN subnetworks as a common intermediate description of service quality instead of conventional QoS parameters. The RBC is introduced to settle the real time TE issue against the vast accumulation of traffic monitoring data. The pilot RBC/USP is implemented on the Linux platform and its performance is investigated.
We found that the average traffic log size is reduced to 0.058% for FTP, and 2.39% for streaming service by using the RBC/USP.
