Abstract
An SDN controller configures a network element as a service edge. The SDN controller configures a service flow associated with a service to receive a required service treatment. The SDN controller configures an entry point to add routing tags on a set of packets associated with the service. The set of packets are routed in accordance with the routing tags. The required service treatment is applied at the service edge and the tags are removed from the set of packets, which are then forwarded to the network.
Claims20
A method comprising:
- requesting a service;
- configuring with an SDN controller a network element as a service edge;
- configuring a service flow associated with the service to receive a required service treatment;
- dynamically configuring with the SDN controller a service entry point to add a routing tag in each packet of a plurality of packets associated with the service so that each packet goes through a specified route to the service edge;
- applying the required service treatment at the service edge;
- and
- forwarding each of the plurality of packets to a network.
A system comprising:
- a processor;
- a storage device;
- an SDN controller;
- a network element;
- the storage device including instructions which when executed by the processor cause the system to perform operations comprising:
- requesting a service;
- configuring with the SDN controller a network element as a service edge;
- configuring a service flow associated with the service to receive a required service treatment;
- dynamically configuring with the SDN controller a service entry point to add a routing tag in each packet of a plurality of packets associated with the service so that each packet goes through a specified route to the service edge;
- applying the required service treatment at the service edge;
- and
- forwarding each of the plurality of packets to a network.
A computer-readable, non-transitory medium storing a program that causes a computer to execute a method comprising:
- requesting a service;
- configuring with an SDN controller a network element as a service edge;
- configuring a service flow associated with the service to receive a required service treatment;
- dynamically configuring with the SDN controller a service entry point to add a routing tag in each packet of a plurality of packets associated with the service so that each packet goes through a specified route to the service edge;
- applying the required service treatment at the service edge;
- and
- forwarding each of the plurality of packets to a network.
