    摘要: In one embodiment, a method includes identifying whether there is a first device in a network that is expected to be associated with a discovery protocol but does not have the discovery protocol turned on. The method also includes providing a notification to a management arrangement when the first device is identified. The management arrangement manages the network, and the notification indicates that the first device is expected to be associated with the discovery protocol but does not have the discovery protocol turned on.

    摘要: In one embodiment, a method can include: (i) receiving an incoming probe packet in a network device; (ii) de-encapsulating the incoming probe packet to provide a packet content portion and a drop result portion; (iii) testing the packet content portion against a local access control list (ACL) to determine a local drop result; and (iv) inserting the local drop result and encapsulating an outgoing probe packet.

    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.

    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: 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: Disclosed are systems and methods for persisting management information indexes across multiple network elements. In particular, methods of detecting and curing potential collisions among a peer group of network elements by use of a hashing function can be provided in accordance with embodiments. For example, a method for maintaining persistence across network elements can include: (i) configuring one of the network elements, and providing a configuration string therefrom; (ii) performing a hashing algorithm on the configuration string to provide a hash value; (iii) determining if any collisions exists between the hash value and corresponding values from among a peer group of network elements; and (iv) assigning the hash value as a management table index when no collision is found, or assigning a new value for the management table index when a collision is found.
