摘要： Exemplary methods for performing distributed data aggregation include receiving Internet Protocol (IP) traffic from only a first portion of the network. The methods further include utilizing a big data tool to generate a summary of the IP traffic from the first portion of the network, wherein a summary of IP traffic from a second portion of the network is generated by a second network device utilizing its local big data tool. The methods include sending the summary of the IP traffic of the first portion of the network to the third network device, causing the third network device to utilize its local big data tool to generate a summary of the IP traffic of the first and second portion of the network based on the summaries received from the first and second network devices, thereby allowing the IP traffic in the network to be characterized in a distributed manner.

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： Methods and apparatus for determining recommended geographic server locations for online social networks by attempting to minimize user-server latency and inter-user communications latency. In an embodiment, geographic and relationship information for a plurality of users is acquired. The plurality of users may belong to one or more networks. The acquired information is transformed into a graph. A first plurality of clusters is generated with a first clustering algorithm. A second plurality of clusters is generated by iteratively examining pairs of the first plurality clusters, and swapping nodes between the examined clusters if it will reduce a total cut weight of the graph and locate each pair of nodes within a defined maximum distance from the centroid of the target cluster. In an embodiment, a method uses a joint analysis approach based upon characteristics of a plurality of existing networks.

摘要： A method for placing services at network devices is disclosed. A network contains a plurality of network devices and the network offers a set of services to subscribers. Each subscriber of the network utilizes a subset of the set of service, where an order of the services is not predefined. The method starts with ordering the services from the most utilized service to the least utilized, and selects services from the most utilized to the least utilized. For each service, a network device is selected so that placing the service adds a least sum of additional delay based on services already placed in the network, and a path for each subscriber utilizing the service is updated to include the service, where the path is an ordered chain of services, and where the service is inserted in the path to result in minimum addition to delay to the subscriber.

摘要： A method is implemented in a network element that functions as one of a plurality of controllers for one of a plurality of areas of a split architecture network. The controller provides a control plane for the area of the split architecture network where the controller is remote from a plurality of switches providing a data plane for the area of split architecture network. The controller facilitates optimized routing across the plurality of areas of the split architecture network by providing limited intra-area link cost data to other controllers of other areas of the split architecture network and to traditional routers of a network including the split architecture network. The limited intra-area link cost data provides costs of each possible shortest path traversal of the area of the controller without providing all internal link cost data.
