    摘要: An apparatus and method for collecting network traffic information is arranged to receive network traffic elements including one or more key fields having respective key field values. The apparatus and method further classify received network traffic elements into one of a plurality of flows dependent on the key field value of one or more key fields defined by a flow profile. The method and apparatus are further configurable to vary the flow profile, create a flow record and export the flow record to a collecting node.

    摘要: A method is provided in one example embodiment and includes receiving a plurality of packets and generating a data record that is based on information associated with the packets. The data record includes a synchronized time window field that defines a time boundary at which data aggregation associated with the data record is stopped, where the synchronized time window field remains constant as the data aggregation associated with the data record occurs. In other embodiments, the method includes creating a new cache entry for new packets arriving at a network element, where the new cache entry is created in response to a value of the synchronized time window field changing. The synchronized time window field can include a window size attribute that defines how long the synchronized time window remains unchanged.

    摘要: In one embodiment, a method includes determining a first template defining a data format for one or more first data records and a second template defining a data format for one or more second data records. The template may be needed to decode the information included in an associated data record. The first template is sent on a first stream of a multi-stream protocol in an ordered fashion, such as SCTP. The one or more first data records are also sent on the first stream in an ordered fashion and include first flow information for data sent through a network device. A second template is sent on a second stream using the multi-stream protocol in an ordered fashion. One or more second data records are sent on the second stream including second flow information for data sent through the network device.

    摘要: A method for generating a traffic matrix is provided that includes receiving a first set of data from a first provider edge element and a second set of data from a second provider edge element, the first and second sets of data including border gateway protocol (BGP) next hop information. The first and second sets of data may then be aggregated. Information that is associated with one or more customer network elements is then filtered out in order to produce a traffic matrix.
