    摘要： A method implemented for network function placement is disclosed. The method optimizes network function placement for each traffic flow, to minimize the overall inter-pod traffic volume. For each traffic flow going through a data center, the method initiates a pod list. The network functions of the traffic flow is sorted in a descending order by resource demanded. Then one network function is selected one at a time according to the descending order. For each network function, the pods in the pod list is sorted in an ascending order by resource available in each pod. The method selects a first pod for the network function when possible. When no pod in the pod list has enough resource for the network function, the method adds a pod with the most available resource from a pod pool to the pod list, and selects the added pod for the network function.

    摘要： According to one embodiment, a method in a cloud infrastructure for multi-level threshold service level agreement (SLA) violation mitigation. The method includes generating a model for an engineered feature (eF); determining thresholds T1, T2, and a maximum threshold Tε for the eF based on the model; estimating a value of the eF based on metrics; responsive to determining that the value of the eF exceeds Tε, modifying the values of T1 and T2 and modifying the estimation frequency and sending to a cloud orchestrator a message indicating that an SLA violation of type Tε has occurred.

    摘要： Exemplary methods include receiving requests comprising of monitoring zones (MZs), each MZ to be allocated a pair of probes in a network, wherein each MZ is associated with a rule identifying a condition for when its probes are to be updated, and wherein each probe in the network is associated with a rule identifying a condition of when it is updated. The methods include determining whether previously allocated pairs of probes in the network can serve as probes for one or more MZs in the requests, wherein a previously allocated pair of probes can serve as probes for a MZ if a rule associated with the MZ is similar to rules associated with the previously allocated pair of probes. The methods include for each MZ that can be served by a previously allocated pair of probes, sending information identifying the MZ and the previously allocated pair of probes.
