In certain embodiments, a network edge device comprises a memory storage, a networking component configured to communicate with a mobile device and a database comprising application attributes, and a processor. The processor, in certain embodiments, is located within the network edge device and is operable to receive application traffic from the mobile device (the application traffic being associated with an application), classify the application traffic by associating the application traffic with an application ID, and send a query comprising the application ID to the database comprising application attributes. In addition, the processor, in certain embodiments, is operable to receive a response, from the database comprising application attributes, comprising one or more application attributes associated with the application, wherein the response is based in part on the application ID, and to enforce a policy based in part on the application attribute.

Application classification and management

In certain embodiments, a method comprises forming a cluster of peered network devices comprising a plurality of three or more peered network devices and a plurality of control information connections between pairs of the peered network devices. The method further comprises classifying a connection by associating the connection with an application, wherein a first peered network device associated with the cluster classifies the connection based at least in part on sequential payload packets associated with the connection, at least some of which the first device receives from other peered network devices associated with the cluster. The method also comprises sending control information over one of the control information connections between the first peered network device and a second peered network device associated with the cluster, wherein the control information comprises information regarding the classification of the connection.

Network device clusters

A machine has a bus, an input port connected to the bus to receive inbound network traffic, an output port connected to the bus to convey outbound network traffic and a processor complex connected to the bus. The processor complex is configured as a pipeline with individual processor cores assigned individual network traffic processing tasks. The pipeline includes a first set of processor cores to construct network traffic trees characterizing the inbound network traffic and the outbound network traffic. Each network traffic tree characterizes traffic type and traffic rate. A second set of processor cores enforces network traffic policies utilizing the network traffic trees. The network traffic policies apply traffic rate control by traffic type for the inbound network traffic and the outbound network traffic.
