The ITU G.1050 specification defines a model of an IP network, appropriate for the testing of how streaming media woud behave across the internet. The model is based on a path having 5 segments:
- a local LAN (wired or wireless)
- an access link to the internet
- an internet of arbitrary complexity
- an access link from the internet
- a distant LAN (wired or wireless) The impairments typical of these segments at various service levels are modelled. 8 standard service level behaviours are defined, covering lightly loaded to heavily congested levels. 133 standard sets of link speeds are defined, covering typical wired and wireless LAN, broadband access link, and backbone characteristics.
The G.1050 model is suitable for testing the behaviour of RTP, UDPTL and other streaming protocols for packet loss and jitter behaviour.
