    <dct:description>&lt;p&gt;Commonly regulators and Internet service providers (ISPs) monitor and publish the offered quality of service (QoS) to improve broadband Internet QoS focusing on transparency and customer empowerment. This is aimed mainly to create competition between ISPs and provide freedom of choice on best operators for customers which is mainly crucial in multi-operators environment. Some of the researches done on differentiated customer traffic to improve QoS mainly used metrics throughput, delay &amp;amp; packet loss only. While others use hardware QoS measurement approach which is expensive than the software and challenging. Moreover other researches on operators and regulators tried to improve QoS based only on performance measurement which does not show the E2E QoS. Whereas in ET, the sole operator of Ethiopia, fixed wireless broadband Internet (FWBBI) is provided in traditional or similar/ equitable manners that is based on best efforts. Despite various customer traffics require variable QoS requirements, some traffics require guaranteed bandwidth such as business critical data applications and others like real time interactive application services such as Voice over Internet (VoIP) and video conferencing are highly sensitive to delay, jitter and packet loss. Hence best effort service offering does not guarantee business critical data applications and user satisfaction&lt;/p&gt;</dct:description>
