A control and monitoring system orders a service chain&#x2014;an order of data flow through a plurality of network nodes&#x2014;based on network node identifiers. The control and monitoring system provide a policy to networking nodes in order to enforce the order of the service chain. In some embodiments, features are implemented to improve the availability of service chains. Such features include load-balancing, fail-over, traffic engineering, and automated deployment of virtualized network functions at various stages of a service chain, among others.

Highly available service chains for network services

A restricted transmogrifying driver platform is described herein. In one or more implementations, a platform is provided that enables a restricted execution environment for virtual private network (VPN) drivers and other transmogrifying drivers. The platform may be implemented as an operating system component that exposes an interface through which drivers may register with the platform and be invoked to perform functions supported by the platform. The restricted execution environment places one or more restrictions upon transmogrifying drivers that operate via the platform. For instance, execution may occur in user mode on a per-user basis and within a sandbox. Further, the platform causes associated drivers to run as background processes with relatively low privileges. Further, the platform may suspend the drivers and control operations of the driver by scheduling of background tasks. Accordingly, exposure of the transmogrifying drivers to the system is controlled and limited through the platform.
