Abstract
A method implemented in a network for placing services in a SDN system is disclosed. The network contains a plurality of network devices managed by a SDN controller and offers a set of services to subscribers. Subsets of the set of services are included in ordered service chains for subscribers. The method starts with determining a list of bandwidth consumption entities of a service for each service, where each bandwidth consumption entity is based on one or more chains of services. Then a weight of each service is calculated based on the list of bandwidth consumption entities of the service and a service with the highest weight within a group of services that have not been placed in the SDN system is selected. The selected service is then placed at a network device based at least partially on calculating bandwidth impacts to the SDN system by the service.
