Abstract
A method of controlling traffic, particularly, a method of setting and executing a traffic control policy in which a time condition is additionally combined is provided. At any specific step of a network that executes a time-based policy, an execution time point of the time-based policy can be determined. Further, a network service provider can provide various application services to a network user using a time-based policy.
Claims6
A method of determining an execution time point of a time-based policy that controls traffic, the method comprising:
- determining, by a policy server (PS) to which the policy is set, whether an execution time point of the policy arrives;
- continuing, if an execution time point of the policy does not arrive, to determine an execution time point of the policy;
- and
- transmitting, if an execution time point of the policy arrives, the policy to a policy management system (PMS), wherein the PMS is connected to policy execution equipment (PEE) that executes the policy, and wherein the execution time point reflects a time condition that is provided independently from the traffic,
- wherein the time-based policy is set based on tuple information that is included in a packet from the traffic and the time condition by the policy server.
A method of determining an execution time point of a time-based policy that controls traffic, the method comprising:
- downloading, by a policy management system (PMS) that is connected to a policy execution equipment (PEE) that executes the policy, the policy;
- storing the policy at a database that is included in the PMS;
- determining whether an execution time point of the policy arrives;
- continuing, if an execution time point of the policy does not arrive, to determine an execution time point of the policy,
- wherein the execution time point reflects a time condition that is provided independently from the traffic,
- wherein the time-based policy is set based on tuple information that is included in a packet from the traffic and the time condition by a policy server.
