ADWISER: An integrated approach for Internet access bandwidth and performance management of an enterprise network

We present a centralized integrated approach, ADWISER, for (i) managing an Internet access link bandwidth, and (ii) for enhancing the performance of an IEEE 802.11 WLAN. Our single-box approach is an extension to our previous work ([1] & [2]), where we focused on meeting TCP performance objectives over WLANs. In this work, we present a novel cascaded packet scheduling algorithm to address the issue of unfair share of wireless channel between competing high speed LAN-WLAN flows and the Internet-WLAN flows. We demonstrate several ADWISER features which highlight our single-box solution in providing policy based Internet bandwidth management, and giving performance guarantees to both LAN and WLAN users of an enterprise.
