Management of Networks with End-to-End Differentiated Service QoS Capabilities

Offering QoS on TCP/IP networks is the object of intense research. New applications, such as telemedicine, distance learning, videoconference and others can only be implemented on environments that ensure QoS for the existing services. Usually, routers are the network resources that undergo changes in order to implement it - hosts have little or no influence. This paper presents an implementation of QoS structures offered directly from the host. It also presents a marking process that is run on the end systems and can be remotely managed via SNMP. A signaling application is also described in order to allow QoS requests to inherited applications that do not perceive QoS service on the networks.
