The invention relates to a synchronized adaptation of a virtual subset of a telecommunication network (R), referred to as a “network slice”, dedicated to an elementary service of a set of services. A more encompassing service is generally composed of several elementary services to which separate respective slices are dedicated. The telecommunication network (R) comprises a plurality of network slices, and these slices are configured according to a plurality of configuration parameters. In particular, at least one second configuration parameter of at least one second slice dedicated to a second elementary service of a set of services is modified on the basis of at least one modification of a first configuration parameter of a first slice dedicated to a first elementary service of the set of services.

A multi-layer network planning system can determine a set of regenerator sites (“RSs”) that have been found to cover all paths among a set of nodes of an optical layer of a multi-layer network and can determine a set of candidate RSs in the optical layer for use by the links between a set of nodes of an upper layer, wherein each RS can be selected as a candidate RS for the links. The system can determine a binary path matrix for the links between the set of nodes of the upper layer. The system can determine a min-cost matrix that includes a plurality of min-cost paths. The system can determine a best RS from the set of candidate RSs and can move the best RS from the set of candidate RSs into the set of RSs for the links. The system can then update the binary path matrix.

In some implementations, a method is provided. The method includes receiving captured packet traffic, the captured packet traffic including a plurality of packets transmitted over a network. One or more communication patterns for each of one or more levels in a network stack are detected based on metadata of the captured packet traffic, each communication pattern indicating communication between two components in the network. The method further includes generating a topology of the network in view of the one or more communication patterns detected for each of the one or more levels in the network stack.

Systems, methods, and software for auto-scaling Virtualized Network Functions (VNF) in a network. In one embodiment, an adaptive engine stores initial rules for a set of auto-scaling rules. The adaptive engine monitors behavior of the network operator in scaling a VNF in response to events, and generates learned rules for the set of auto-scaling rules based on the behavior of the network operator. The adaptive engine adjusts a sequence of the initial rules and the learned rules in the set of auto-scaling rules. The adaptive engine predicts a future event in the network that will activate scaling of the VNF, and auto-scales the VNF for the network based on the set of auto-scaling rules before occurrence of the future event.

Described are examples for providing a system for managing configuration and policies for a virtualized wide area network (vWAN) support on a wide area network (WAN). The vWAN includes a plurality of virtual network entities associated with geographic locations including the physical computing resources of the WAN and virtual connections between the virtual network entities. The system includes a network safety component for managing configurations and policies of the vWAN on the WAN. The network safety component receives a change to a policy or configuration of the vWAN from an operator of a network connected to the vWAN. The network safety component evaluates a set of safety rules for the operator based on the change and a network state of a physical WAN underlying the vWAN. The network safety component generates an error message in response to at least one of the set of safety rules failing the evaluation.
