Sarah Bailey talks network evolution with Dom Robinson, Co-Founder and Director, id3as.
Sarah Bailey: How will mobile networks evolve to support mobile video?
Dom Robinson: eMBMS (LTE Broadcast) will deepen the relationship between traditional broadcasters and mobile operators as they start to scale live linear delivery. As these models develop we will see a greater update of VOD services as a follow through.
What is the role of edge computing in video delivery?
Increasingly it will help offload core workflow tasks, but at the moment a round of redevelopment needs to occur. The operators/carrier CDNs will probably lead the way with the future architecture since they are less committed than the pure plays, while those pure play CDN providers will watch and gradually ape the carriers in an attempt to avoid he balkanisation of their market into each carrier CDN.
eMBMS and DOCSIS 3.1 are going to increase edge expectations, and this will require well architected CDN with deep integration with the access networks – deeper than is currently offered.
What will be the impact of virtualisation and the integrated data plane of content delivery networks?
SDN/NFV are coming. If you still think the CDN is a dedicated HTTP chunk delivery service and that is that then you miss the diversification of the end user devices – if you want to remain agile and service the clients as they demand/remain relevant you need to orchestrate properly.
You can use techniques such as id3as does (Erlang) and build proprietary, highly efficient models, or you can join the standards track and focus on interoperability with other networks – even if there is a LONG way to go until SDN/ NFV really scales in the way proprietary models can.
However, one thing you cannot do is stand still.
What is the future of content delivery in the cloud?
The cloud is an economic term for services that scale down (with costs) rather than remaining costly. Under-utilised content traffic often ebbs and flows and if you can outsource the infrastructure it will often lead to economic benefits during the ebbs. However there are still strong arguments for operating your own virtual hosting or even ‘real’ hosting for 24/7 non-volatile services.
Either way, as content providers seek to reach ever more active audiences the demand for all types of service models is only increasing.
Dom Robinson is a confirmed keynote at Content Delivery World (6th – 7th October 2015)
