Description
Summary:NeCoMan middleware customizes dynamic adaptation of point-to-point-based network services in programmable networks, taking into account the properties of the network services involved as well as the reconfiguration semantics. This article focuses on safe runtime adaptation of point-to-point-based network services in programmable networks. Many network services such as compression, fragmentation, reliability, and encryption conform to a point-to-point-based distributed-service model. This model represents a pair of tightly coupled components (not necessarily situated on neighboring nodes) that must cooperate to offer a distributed service. To prevent the runtime addition, replacement, or removal of these network services from jeopardizing a programmable network's correct functioning, the network programmer must coordinate the adaptation of the protocol stacks accommodating the service components.
