Due to the increasing popularity of smartphones and tablets, mobile apps are becoming the preferred portals for users to access various network services in both residential and enterprise environments. Predominantly using generic HTTP or HTTPS protocols, traffic from different mobile apps is largely indistinguishable. This loss of visibility into mobile app(More)
MAPPER is a system for enforcing user-specific policies based on the availability of access nodes that support the capability to dynamically load and execute processing modules on the data path. This work leverages a network access node that, after authenticating a connecting user, loads a set of lightweight virtual machines that process traffic terminated(More)
This work shows how the performance of a network function can be estimated with an error margin that is small enough to properly support orchestration of network functions virtualization (NFV) platforms. Being able to estimate the performance of a virtualized network function (VNF) on execution hardware of various types enables its optimal placement, while(More)
Virtual Network Functions (VNFs) are often implemented using virtual machines (VMs) because they provide an isolated environment compatible with classical cloud computing technologies. Unfortunately, VMs are demanding in terms of required resources and therefore are not suitable for resource-constrained devices such as residential CPEs. However, such(More)
Virtual Network Functions (VNFs) are often realized using virtual machines (VMs) because they provide an isolated environment compatible with classical cloud computing technologies. However, VMs are demanding in terms of required resources (CPU and memory) and therefore not suitable for low-cost devices like residential gateways. Such equipment often runs a(More)
