QoSME: Toward QoS management and guarantees

QoS (Quality of Service) is an emergent necessitate of next generation Internet, and has been widely investigated by the computer and communication community. QoSME (Quality of Service Management Environment) is presented in this paper as a general solution of end application QoS management and guarantees. Some related research works briefed firstly demonstrate that delivering QoS to end applications easily is highly demanded. QoSME architecture employs the current prevailing network protocols and technologies (e.g., IP and ATM), and incur; a QoS environment that interfaces end applications with underlying QoS provisioning services and manages application QoS through monitoring real-time network performances. The QoSME system model is deployed with its system components including QoSockets (the socket-like runtime environment), QoS MIBs (Management Information Bases), SNMP (Simple Network Management Protocol) agents and APIs (Application Programming Interfaces). Two typical QoS-demanding multimedia applications built using QoSME are introduced. Finally, some conclusions and future works are presented.
