Why The IP -based Real -Time Media Network # 8 © ALC NetworX GmbH 2018 Vision: a platform -independent content exchange technology Requirements: • scalable • fast • shareable • flexible • reliable • routable • non -proprietary • based on standards 2008 The IP -based Real -Time Media Network # 10 © ALC NetworX GmbH 2018 Audio over IP Audio over Ethernet AVB Media streaming ACIP RTP Layer 1 Layer 2 Layer 3 Livewire Dante A -Net MADI AES50 TCP UDP unicast multicast CobraNet EtherSound Confusion Market Evaluation Technology Assessment  IP! The IP -based Real -Time Media Network # 11 © ALC NetworX GmbH 2018 Why IP -based Networking? • General advantages of networking: Reliability, flexibility, versatility, accessibility, scalability, cost advantage, maintenance efficiency, … • Availability: IP -capable network equipment and infrastructure readily available and widely deployed • Based on standards: IP standard protocols (the "internet protocols") are widely supported (e.g. RTP/RTCP, RTSP, IGMP, SDP, DHCP, DNS etc.) • Routing capability: content can be routed across campus networks and WAN connections without technology change • Convergence: PCs can participate on the network without dedicated hardware • Future -proof: IP -based services are growing into all areas of communication The IP -based Real -Time Media Network # 12 © ALC NetworX GmbH 2018 Audio over IP Audio over Ethernet AVB Media streaming ACIP RTP Layer 1 Layer 2 Layer 3 Livewire Dante A -Net MADI AES50 TCP UDP unicast multicast CobraNet EtherSound Confusion Market Evaluation Technology Assessment Take or Make?  IP!
