Abstract
A programming method and a programming apparatus for a core routing and switching system are provided. The method includes: obtaining a number of routing nodes and a number of resource types in each routing node in the core routing and switching system; judging whether a first requirement for resources in the routing nodes is changed to a second requirement; judging whether resources in a first routing node group corresponding to the first requirement meet the second requirement if the first requirement is changed; searching for a plurality of second routing node groups with resources meeting the second requirement if the resources in the first routing node group do not meet the second requirement; calculating a plurality of migration overheads corresponding to the plurality of second routing node groups; selecting a second routing node group corresponding to a smallest migration overhead from the plurality of second routing node groups.
