Quality of service for multicasting using NICE
Marc Brogle, Sebastian Barthlomé, Torsten Ingo Braun · 2010
To distribute data from one sender to multiple receivers efficiently and concurrently, multicasting is one of the most appropriate mech-anisms. Application Layer Multicast (ALM), often also referred to as Overlay Multicast, has been introduced to overcome the limita-tions of IP Multicast. The OM-QoS (Quality of Service for Over-lay Multicast) framework aims to enable QoS for different ALM protocols. We applied the OM-QoS mechanisms to the Overlay Multicast protocol NICE and performed evaluations in QoS envi-ronments using resource reservations and measurement based QoS. Our evaluations show that we can support the QoS requirements of all paths in the multicast tree, while introducing an acceptable over-head in terms of delay.
