Abstract

Embodiments are directed towards managing communication over a network with a packet traffic management device that performs delayed proxy action. The PTMD includes a buffer for buffering network traffic. Also, the PTMD includes proxy data paths and standard data paths. Network policies associated with the network flows may be determined using the buffered data. If a determined network policy includes proxy policy rules it is a proxy network policy. Then the network flows are associated with a proxy data path. If the buffer is exhausted, the network flow is associated with a standard data path before a policy is determined. Otherwise, if the network policy includes only standard policy rules, the network flows are moved to a standard data path. After the network flow is associated with a data path, the network traffic may be communicated until it is closed or otherwise terminated.

Dependent claims

A method for managing communication over a network with a traffic management device (TMD) that is operative to perform actions, comprising:

buffering network traffic from one or more network flows on the TMD, wherein the TMD includes a proxy data path and a standard data path for communicating the network traffic to an endpoint, wherein an amount of the buffering is in part based on one or more types of the network traffic;
determining one or more network policies that is associated with the one or more network flows based on a portion or more of the buffered data;
employing the one or more network policies that include one or more proxy policy rules associated with a subscriber to select the proxy data path for association with those network flows associated with the subscriber;
employing the one or more network policies that include just one or more standard policy rules to automatically select the standard data path for the one or more network flows that are unassociated with the subscriber;
employing the one or more network policies that include policy rules for the one or more network flows that are unassociated with the subscriber and exceed an available amount of buffering to automatically select the proxy path for association with these one or more network flows;
and
automatically communicating the network traffic from the one or more network flows on the network to the endpoint over the selected one of the proxy data path or the standard data path until the one or more network flows is terminated.

4 more elements

determining one or more network policies that is associated with the one or more network flows based on a portion or more of the buffered data;
employing the one or more network policies that include one or more proxy policy rules associated with a subscriber to select the proxy data path for association with those network flows associated with the subscriber;
employing the one or more network policies that include just one or more standard policy rules to automatically select the standard data path for the one or more network flows that are unassociated with the subscriber;
employing the one or more network policies that include policy rules for the one or more network flows that are unassociated with the subscriber and exceed an available amount of buffering to automatically select the proxy path for association with these one or more network flows;
and
automatically communicating the network traffic from the one or more network flows on the network to the endpoint over the selected one of the proxy data path or the standard data path until the one or more network flows is terminated.
