In one embodiment, a network functions virtualization infrastructure can be managed in a decentralized fashion. A front end can receive a request to provision a virtualized network function. The front end can create service descriptors for the request according to the virtualized network function, the service descriptors comprising a hierarchy of information elements organized based on distributed back-end agents operable to provision and manage the virtualized network function. The front end can store the service descriptors in a distributed data store.

Systems and methods for triggering service activation include starting a vCPE instance in response to a request for a service, instantiating a service container for the requested service and starting the service in the service container, installing a fast path entry for the service container in a local bridge table, detecting an idle timeout of the service and labeling the local bridge table entry for the corresponding service container as inactive, notifying a cloud services manager that the service container is inactive, and removing the service container.

In one embodiment, a logical packet switching device has its switching fabric extended between multiple physical devices, such as, but not limited to, over one or more networks (e.g., over tunnel(s), point-to-point link(s), and/or public and/or private L2 or L3 network(s)). In particular, one embodiment extends the switching fabric between multiple different physical devices by effectively merging, at least from the perspective of ingress and/or egress line cards, a switching fabric in each of these multiple different physical devices. In this regard, an ingress lookup operation in a first physical device of one embodiment produces information which is used by the switching fabric in a different physical device to forward a packet to the appropriate egress line card in the different physical device. Further, one embodiment includes line cards which can be used to both extend the switching fabric as well as communicate with packet switching and other devices that are independent of the logical packet switching device.
