This paper presents the elements of a framework enabling scalable service deployment over programmable heterogeneous networks. For ease of service deployment it is expected that network management tools will require participation of the network itself in order to be able to scale to a very large number of network elements with widely varying programmability levels. The type of services considered is very broad, ranging from routing services involving selected nodes of a network to end-to-end services spanning the entire network. The underlying hierarchical structure and the representation of capabilities used by the mechanism to deploy new services into a network automatically, are presented. The algorithmic structure of the mechanism described is then illustrated by several examples showing its applicability and complexity.
Keywords: Automated service deployment, programmable networks, network management.
