Methods, systems, and computer readable media for automatic, repetitive enforcement of a policy rule according to a schedule are disclosed. According to one aspect, a method for automatic, recurrent enforcement of a policy rule includes providing, to a node for enforcing policy rules in a telecommunications network, an automatically recurrent policy rule, the policy rule defining an enforcement activation condition and including an enforcement recurrence attribute; and using, at the node, the enforcement activation condition and the enforcement recurrence attribute to recurrently activate the enforcement of the policy rule according to the enforcement recurrence attribute.
A method of providing QoS to a session from a client to a first network includes providing data packets from the client to be conveyed in a session from the client to a first network, inserting each of the data packets into an encapsulating packet, and transmitting the encapsulating packets through the second network to the first network, forming a tunnel through the second network. The method includes receiving the encapsulating packets at a terminating device in the first network. The terminating device removes the encapsulating headers to recover the data packets. The method includes determining an association between the packet headers of the data packets and the encapsulating headers, identifying data packets requiring QoS, and using the association to identify encapsulating packets corresponding data packets requiring Quality of Service. The method includes applying QoS to the encapsulating packets, corresponding to the session of data packets requiring the QoS, being conveyed through the tunnel.
