Abstract

This article focuses on safe runtime adaptation of point-to-point-based network services in programmable networks. These services consist of tightly coupled distributed components that must cooperate to implement a network service. Preserving network integrity during the addition, replacement, or removal of these services requires coordinated adaptation of the protocol stacks accommodating the service components. The NeCoMan middleware addresses this problem. The novelty of this middleware is its ability to customize the adaptation process, taking into account the properties of the network services that are involved as well as the reconfiguration semantics.
