A method is disclosed for transmitting system management requests to computer systems along a network path using a network control protocol, such as RSVP. For example, an originating node may send a single system management request along a path to a destination node using a network control protocol. Each computer system along the network path may analyze the network control protocol message to determine whether the message contains a system management request. If a system management request is found in the message, the computer system may perform the system management function identified in the request, and respond to it.

Performing path-oriented systems management

A method includes receiving a request to provision a path associated with at least a portion of a packet network and determining whether a router is associated with the path in the packet network. The method also includes provisioning a first connection between a first gateway and a second gateway when the router is not associated with the path. The method further includes provisioning a second connection between the first gateway and the router and a third connection between the router and the second gateway when the router is associated with the path. In addition, the method includes at least one of associating and disassociating a first endpoint of the first gateway and a second endpoint of the second gateway with one or more of the connections.

System and method for provisioning connections as a distributed digital cross-connect over a packet network

A method, device, and computer-readable medium are disclosed for automatically activating a probe configured to generate test network traffic in response to evaluating a policy that accounts for aggregated information that describes traffic that was processed by a network device. The method includes storing a policy, and evaluating the policy based at least in part on an item of received aggregated information that describes a set of packets that were processed by the network device and sent or received on a network. The probe is activated at least partially in response to evaluating the policy. The probe generates test packets to emulate one or more applications, services, or devices communicating on the network.

Autonomous performance probing

A system and method provides a managed resource instrumentation application on a network device to instrument a managed network device component. The managed resource instrumentation application includes an application programming interface (API) that is common to two or more management agents that are implemented on the device, the management agents being configured to process network management instructions that are in different respective protocols. The API is common to the management agents, to provide access by the management agents to the managed network device component via the common API.

Application of an embedded instrumentation interface definition language

Methods and apparatus for efficient decentralized information dissemination in a network are discussed herein. The decentralized information dissemination techniques are based on non-deterministic protocols such as gossip-based protocols. An example method for dissemination of information in a network can include: selecting a destination node from a set of neighboring nodes using a gossip-based protocol; transmitting a message to the destination node; and receiving a feedback response from the destination node. The feedback response can include a level of usefulness of the message to the destination node. In addition, each neighboring node in the set can be associated with a selection weight, and the selection weights can be related to a probability of selecting each neighboring node in the set as the destination node using the gossip-based protocol. Upon receiving the feedback response, the method can include adjusting the selection weight of the destination node based on the feedback response.

Methods and apparatus for efficient decentralized information dissemination in a network

Techniques in a data processor for translating an object-oriented data model to a YANG data model are described. In one embodiment, for example, a translator system is described for translating data representing an object-oriented data model construct to a data representing one or more YANG data model statements, the translator system comprises: an object-oriented data model construct identifier for identifying data representing an object-oriented data model construct; an object-oriented data model construct-to-YANG data model statement translator for translating the identified data to translated data representing one or more YANG data model statements; and a storing module for storing the translated data in one or more non-transitory computer-readable media.

Translating an object-oriented data model to a YANG data model

A method is disclosed for managing a network entity that is initiated by the network entity, the method comprising the computer-implemented steps performed at the network entity of monitoring the network entity; periodically evaluating one or more specified conditions at the managed network entity; when one or more of the specified conditions are satisfied, then gathering specified information from the managed network entity, preparing a message that includes the specified information and the specified conditions that were satisfied, and sending the message to a management point.

Method and apparatus providing device-initiated network management

An apparatus is disclosed for creating and storing policy data records comprising data identifying network policy decisions. After a data packet is received, a network policy decision is made based on information in the packet and one or more network policies. A policy data record identifying the network policy decision is created, and the policy data record is stored.

Tracking policy decisions in a network

Techniques for system (syslog) messages are provided. As syslog messages are generated a dual sequence number is maintained for each syslog message. The first sequence number is consistent for each syslog message and represents a total number of syslog messages received. The second sequence number is maintained as a total message count for a specific session for which a syslog message is assigned.

Techniques for sequencing system log messages

In one example embodiment, a system and method are illustrated that includes defining an interface that is independent of a management interface associated with a management agent. This interface is configured to instrument a network device component. The system and method also includes generating an API from the interface. The system and method further includes binding the management agent and the API to implement the management interface associated with the management agent.

In an embodiment, a data processing system comprises a repository configured to store a plurality of event message definitions for error messages, syslog messages, or other notification messages that may be emitted by one or more managed network elements; event annotation logic coupled to the data repository and configured to receive and store one or more annotations to each of the event message definitions, wherein each of the annotations specifies event context information to be collected in the managed network elements when an associated event message occurs; event forensics definitions generator logic coupled to the event annotation logic and configured to generate an event forensics definitions file capable of interpretation by one or more managed network elements and comprising event type identifiers and context information identifiers for context information to be collected, and configured to cause distributing the event forensics definitions file to the one or more managed network elements.
