Fundamentally, public services must be of high quality so as to satisfy the wants and needs of the beneficiaries. But it’s worrisome to discover that in Uganda, public services provided are of poor quality due to unethical behaviors and wanting leadership. The purpose of this study is to show that transformational leadership can advance ethical culture to spur provision of quality services. A r...

Constraint-based routing is an invaluable part of a full-fledged Quality of Service architecture. Unfortunately, QoS routing with multiple additive constraints is known to be a NP-complete problem. Hence, accurate constraint-based routing algorithms with a fast running time are scarce, perhaps even non-existent. The need for such algorithms has resulted in the proposal of numerous heuristics an...

Workflow management systems (WfMSs) have been used to support various types of business processes for more than a decade now. In ecommerce processes, suppliers and customers define a binding agreement or contract between the two parties, specifying quality of service (QoS) items such as products or services to be delivered, deadlines, quality of products, and cost of service. Management of such...

The device for providing consolidation of preferential resource quality of service constraints specified by a source user and adestination user in a communication network has two quality of service translators receiving preferential resource constraintsinput from the source and destination users respectively. The translators translate input QOS requirements, for each of thesourc...

The article covers the two most important architectures for providing Quality of Service at the network and transport layer, the Integrated Services (IntServ) and the Differentiated Services (DiffServ) architecture, both proposed by the Internet Engineering Task Force (IETF). It describes the basic characteristics of each architecture, provides a comparison between them and outlines the current...

2. Latency. Latency, also known as delay, is a measure of the time it takes to traverse the network, including going through any intermediate routers. It represents the elapsed time between a sending node sending a packet and receiving node receiving that packet. For example, on my system, a local loopback (sending a packet back to the same machine) gives me a latency of 0.043 ms (milliseconds)...
