    摘要: In one embodiment, a method includes obtaining a first packet that has a first payload. The first payload identifies a first path between endpoints traversed by the first packet, and identifying information associated with a first node associated with the first path traversed by the first packet. The identifying information includes an arrival time that identifies approximately when the first packet arrived at the first node and a leaving time that identifies approximately when the first packet left the first node. A first service level agreement (SLA) parameter of the first path is determined by analyzing the arrival time and the leaving time, comparing the first SLA parameter with a second SLA parameter associated with a second path traversed by a second probe packet, and selecting the first path for sending packets if the first SLA parameter indicates a higher SLA level than indicated by the second SLA parameter.

    摘要: Particular embodiments provide a virtual responder that can be contacted by any number of senders. When a sender wants to perform a measurement test with a real responder, the sender sends a control message to a virtual responder. The virtual responder is configured to determine a real responder based on real responder selection metrics. The virtual responder may poll the real responders at certain times to receive the real responder selection metrics. The virtual responder then selects a real responder from a plurality of real responders based on the real responder's selection metrics. The virtual responder then sends contact information for the selected real responder to the sender device. This allows the sender device to contact the selected real responder to perform the measurement test with a real responder.

    摘要: A method of persisting SNMP (Simple Network Management Protocol) variable values associated with SNMP object IDs for an SNMP managed network element across network element reloads comprises implementing a generic persist operation at the network element; and defining, in conjunction with the generic persist operation, at least one object ID for which a value is to be persisted.

    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: 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.
