OPNFV Summit 2015

While little discussed, there is a solid case in placing some VNFs at the edge of the network, but this notion implies a distributed model that VNFs were not originally created to address. One of the problems in placing VNFs at the network edge is that the edge equipment may be very cost sensitive and in many cases, consumer grade.

These consumer-grade devices cannot support a virtual container such as a KVM because of the huge memory requirements of an additional OS. A Docker container has been proposed and implemented with great success.
