To provide streaming services with high quality and low latency, service providers maintain a quantity of points of presence (PoPs), several data centers and a backbone network for stream ingesting, transcoding and distribution.

Data centers host the resources to provide computationally intensive business, like video transcoding. After that, content will be distributed to PoPs or CDNs, or saved in local or remote storage. A typical streaming data center is designed to separate the storage and business network, which hold different unicast or multicast traffic. Asterfusion CX-N series switches based on Marvell ASIC with low latency and sufficient bandwidth can build both storage and business network with Leaf-Spine architecture.

Backbone network can be a WAN or MPLS-based network, usually without multicast capabilities. Large scale NAT capacity is needed in the gateway to realize unicast NAT, multicast NAT, or multicast-to-unicast NAT, which is also called multicast service reflection. Asterfusion X-T series switches with P4 programmable capability provide the possibility to meet different demands on border gateways.
