Systems and methods include receiving Interior Gateway Protocol (IGP) messages from one or more network elements in a network; extracting timing information from any of the IGP messages where the timing information includes timing reference for a given network element for any of frequency, phase, and time; and storing the timing information. The steps can further include one of displaying a Graphical User Interface of the network including an operational timing trail for any of frequency, phase, and time; and displaying the timing information for the one or more network elements via a Command Line Interface (CLI).

Network timing topology discovery and visualization using interior gateway protocols

Systems and methods for analyzing power or energy consumption parameters measured at each of a plurality of nodes or Network Elements (NEs) of a network are provided. A system, according to one implementation, includes a processing device and a memory device configured to store computer logic. The computer logic, for example, may be configured to enable the processing device to receive a power consumption value corresponding to an amount of energy expended at each of a plurality of NEs in a network. Also, the computer logic may be configured to enable the processing device to calculate a cumulative power consumption total from the power consumption values associated with the NEs arranged along a path in the network.

Calculating cumulative power consumption along a path in a network

Systems and methods include, in a node having a plurality of Media Access Control (MAC) addresses with a source MAC address for an application and with the node connected to Network Termination Equipment (NTE) having flooding disabled, configuring the node to periodically send a packet to the NTE with the source MAC address for the application to pre-populate a forwarding database in the NTE; and transmitting the packet to the NTE periodically such that the NTE receives the packet and installs the source MAC address in its forwarding database for reachability thereto despite the disabled flooding. The plurality of Media Access Control (MAC) addresses can include a chassis MAC address and the source MAC address for the application. The packet can be a no-operation packet which requires no processing by the NTE except installation of the source MAC address for the application.

Systems and methods include, for a plurality of services operating on a plurality of network elements in a network, determining attributes for one or more events that periodically occur; and providing a configuration based on the determined attributes to the plurality of network elements for configuring the associated network elements, wherein the configuration controls and coordinates when actions associated with the one or more events occur, across the plurality of network elements and across one or more protocol layers.

Coordinated and scheduled standards-based intervals in network elements

Systems and methods of coordinating and scheduling intervals in a network element in a network include configuring one or more attributes of a plurality of timer-based events at the network element, wherein the plurality of timer-based events include protocol-based actions which are performed responsive to expiry of an associated timer, and wherein the one or more attributes define when the protocol-based actions occur; operating one or more services at one or more protocols; and performing associated protocol-based actions based on the one or more attributes and based on expiry of the associated timer.

Clock synchronization in a network includes receiving, by a slave network device from a master network device via at least a intervening network device, a timing packet comprising a transmission timestamp and a residence time. The transmission timestamp is based on a master clock of the master network device. The residence time corresponds to a delay of the timing packet traversing the intervening device. Clock synchronization in a network further includes generating, by the slave network device in response to receiving the timing packet, a receiving timestamp based on a slave clock of the slave network device, and generating, based at least on the transmission timestamp, the residence time, and the receiving timestamp, a time difference between the master clock and the slave clock. Clock synchronization in a network further includes synchronizing, based at least on the time difference, the master clock and the slave clock.
