Abstract

A method is provided for ensuring that specific traffic flows are adequately prioritized in a public packet communication network even when the network is heavily congested. Per-flow QoS capability is added to VPN tunnels. Connection requests are routed through a specific port in an access provider's network to designated VPN gateway. Deep packet inspection is performed on traffic through the port in an attempt to determine whether the connection request was accepted. If the connection request was accepted, the traffic flows associated with that session may be given a specific priority of QoS level when transiting a packet access network.
