A method provides for the dynamic traffic prioritization in a communication network. The method electronically monitors traffic in a communication network and determines when traffic exceeds configured thresholds on the links of the communication network. Thus, the method determines a link which is potentially about to be congested in the communication network. The method categorizes the traffic on this link by an end system attached to one end of the potentially congested link into a plurality of priority categories using application layer parameters. Using a re-direct capability of the end system, the method re-directs at least one of the pluralities of priority categories of traffic to an alternate Internet Protocol address. The method uses preconfigured Quality of Service mechanisms on the provider edge router attached to the other end of the potentially congested link to guarantee a predetermined amount of bandwidth capacity of the link to traffic destined to the alternate Internet Protocol address.

Method and system for dynamic traffic prioritization

A method, network, and computer program product are provided for traffic flow quality of service. A quality of service priority table is received for services defined by a user at the network, and the quality of service priority table includes quality of service levels for the services. Traffic flows are determined to correspond to packets being communicated over the network for the user. The traffic flows are mapped to services. The traffic flows are mapped to the quality of service levels for the services. The quality of service levels are assigned to the traffic flows as assigned quality of service levels corresponding to the services. Each of the traffic flows is routed over the network according to its assigned quality of service levels, respectively.

Method, network, and computer product for flow based quality of service

A method includes sending a first redirect instruction to a first client in response to a first session request received at a service address, and establishing a first session with the first client in response to a second session request received at the first redirect address indicated by the first redirect instruction. Additionally, the method includes determining a first service interval has passed, and sending a second redirect instruction to a second client in response to a third session request received at the service address after the first service interval has passed. The method still further includes establishing a second session with the second client in response to the fourth session request received at the second redirect address indicated by the second redirect instruction after the first service interval has passed, and rejecting the fifth session request received from a third client at the first redirect address after the first service interval has passed.
