摘要： An approach to duplicating network traffic is described. In one approach, a method of creating multiple copies of network traffic is detailed. The method involves receiving network traffic, producing a duplicate copy of the network traffic, and forwarding the duplicate copy to a monitoring port. The monitoring port forwards copies to a number of indicated ports.

摘要： Measures for configuring a network aggregation device in a network. First routing data for a plurality of internet protocol (IP) flows configured on at least one edge device of a service provider network is identified. The edge device is located towards the service provider network from the network aggregation device. At least one utility metric for at least one IP flow in the identified plurality of IP flows is calculated. The at least one utility metric is calculated at least in part on the basis of one or more destination IP addresses associated with the at least one IP flow. A subset of IP flows from the identified plurality of IP flows is selected at least in part on the basis of the calculated at least one utility metric. Second routing data for the selected subset of IP flows is configured on the network aggregation device.

摘要： Methods implemented in an electronic device are disclosed for dynamically collecting traffic flow in a SDN system. For each of a plurality of sets of traffic flows, the method causes a monitor to be configured to collect traffic statistics. The monitors are instructed to collect traffic statistics, and the traffic statistics are received. For each monitor, the method determines if the received traffic statistics are within a set of acceptable limits or not, wherein the set of acceptable limits includes one or more of an upper bound and a lower bound. For each of the sets of traffic flows of which the received traffic statistics were determined outside of the acceptable limits, the method causes a change of increase or decrease of collection of the traffic statistics of the traffic flows.

摘要： A system to detect anomalies in internet protocol (IP) flows uses a set of machine-learning (ML) rules that can be applied in real time at the IP flow level. A communication network has a large number of routers that can be equipped with flow monitoring capability. A flow collector collects flow data from the routers throughout the communication network and provides them to a flow classifier. At the same time, a limited number of locations in the network monitor data packets and generate alerts based on packet data properties. The packet alerts and the flow data are provided to a machine learning system that detects correlations between the packet-based alerts and the flow data to thereby generate a series of flow-level alerts. These rules are provided to the flow time classifier. Over time, the new packet alerts and flow data are used to provide updated rules generated by the machine learning system.

摘要： Systems and methods to support intra-application flow prioritization are disclosed herein. User equipment (UE) may be configured to communicatively couple to an Evolved Universal Terrestrial Radio Access Network (E-UTRAN) Node B (eNB). The eNB may transmit packets from the UE to an evolved packet core (EPC), which may transmit schedule packets to an application function (AF) via a network. The AF may provide classification information and prioritization information for a plurality of intra-application flows transmitted between the AF and the UE. The EPC may classify uplink and/or downlink traffic into the intra-application flows and mark and/or schedule the traffic based on the prioritization information. Absolute and/or modular length, payload values, and/or packet type may be used to classify the traffic into the intra-application flows.

摘要： A telecommunication system uses a dynamic bandwidth allocation (DBA) algorithm based on current load conditions for controlling transmissions to a plurality of access modules of an access node in order to achieve a fair allocation of network bandwidth at the access node. As an example, access modules at an access node communicate via a control channel with dynamic bandwidth allocation (DBA) logic that receives load information from each of the access modules. Using such load information, the DBA logic dynamically controls the upstream data rates so that a fair allocation of network bandwidth is achieved across all of the access modules. Specifically, the data rates are controlled such that packet flows for services of the same class achieve the same or similar performance (e.g., average data rate) regardless of which access module is receiving each respective packet flow.
摘要翻译：电信系统使用基于当前负载条件的动态带宽分配（DBA）算法来控制到接入节点的多个接入模块的传输，以便在接入节点实现网络带宽的公平分配。作为示例，访问节点处的访问模块通过控制信道与从每个访问模块接收负载信息的动态带宽分配（DBA）逻辑进行通信。使用这样的负载信息，DBA逻辑动态地控制上行数据速率，以便在所有访问模块之间实现公平的网络带宽分配。具体地，数据速率被控制，使得对于相同类的服务的分组流实现相同或相似的性能（例如，平均数据速率），而不管哪个接入模块正在接收每个相应的分组流。
