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.

A system and methods for pre-configuring echo cancellers are shown and described. The system includes a storage device for storing one or more settings of the echo cancellation parameters developed during one or more previously established data connections, and an echo canceller for cancelling echo associated with one or more data connections according to echo cancellation parameters, the echo canceller initially configuring the echo cancellation parameters according to settings developed during previous data connections.

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.

Streaming of templates and data records in individual streams using a multistream protocol

A method of aggregating network traffic flows for network traffic elements is described. The traffic elements are characterized by a plurality of characteristics having respective values, where a flow profile is formed by classifying each element into one of a plurality of flows dependent on its characteristic value. The method comprises the steps of obtaining an instantaneous flow profile and aggregating flows from the flow profile having a common value for a characteristic.

Method and apparatus for aggregating network traffic flows

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.

Collecting network traffic information

Lighting apparatus

In one embodiment, a networking device includes logic encoded in one or more tangible media for execution and when executed operable to cause performing receiving a command to collect a unique object identifier that represents a unique management information base (MIB) object; retrieving, in response to receiving the command, a Simple Network Management Protocol (SNMP) MIB variable or table that corresponds to the MIB object; creating an Internet Protocol Flow Information Export (IPFIX) template data structure that includes the object identifier; in which the object identifier is encoded in the IPFIX template data structure as a string that has a variable length; and exporting the encoded object identifier with the variable length string.

Exporting management information base data using IPFIX

A method of monitoring network traffic flows of network traffic elements between locations in a data communications network is disclosed. The method comprises the step of classifying, as a first flow, traffic elements from a first to a second network location sharing a flow characteristic. The method further comprises the steps of classifying, as a second flow, traffic elements from said second to said first network location sharing said flow characteristic correlating said first and second flows.
