    <subfield code="a">&lt;p&gt;The need for timely delivery of real time and mission-critical applications has led to a high demand&lt;br&gt;
for end-to-end QoS guarantees. Service providers, including Ethio telecom, have deployed&lt;br&gt;
mobile backhaul in addition to IP core network with separate MPLS domains for each&lt;br&gt;
network. Internal network topology of one domain and its policy implementations are proprietary&lt;br&gt;
information and inter-domain routing must be done without detailed knowledge of the entire&lt;br&gt;
network topology, policies and performance of the other domains. Lacks of global coordination&lt;br&gt;
between policies used in different domains, limitations of BGP for implementing end-toend&lt;br&gt;
QoS in inter-domain routing and its slow convergence during network failure are major&lt;br&gt;
challenges of the current inter-domain routing architecture&lt;/p&gt;</subfield>
