Quality of Service in Telemedicine

Telemedicine is one of the fastest growing fields with several innovations happening in managed health-care. With Internet and its infrastructures playing important role in the success of this field, it is not advisable to run some of the critical applications like high quality audio and video involved in telemedicine without proper quality of service (QoS) built on to the network. This paper focuses on two telemedicine setups that have been implemented on different backbone technologies. The first case discusses a virtual critical care unit that is setup for communication on an asynchronous transfer mode (ATM) backbone and a possible model on how QoS for important traffic streams can be achieved in ATM. The second case discusses a minimal access operation that was remotely conducted on a patient with the help of telerobotics on a multi protocol label switching (MPLS) setup and provides a possible solution for achieving quality of service through MPLS in that scenario.
