摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing configurations of telecommunications nodes. In one aspect, a system includes a file server; a subtending device coupled to the file server, and a telecommunications node coupled to the subtending device. The subtending device can include one or more line cards that connect one or more telecommunications nodes to a network. The telecommunications device receives, from the file server and based on provisioning information provided by the subtending device, an auto-config file for the telecommunications node and parses the auto-config file to identify a first filename of a unit-specific configuration file. A wildcard value in the first filename is replaced with a unit-specific identifier, and a unit-specific configuration file is requested from the file server. One or more parameters of the telecommunications node are configured based on a response to the request.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing device firmware. In one aspect, a system includes a file server; a subtending device coupled to the file server, and a telecommunications node coupled to the subtending device. The subtending device can include one or more line cards that connect one or more telecommunications nodes to a network. The telecommunications node receives, from the subtending device, a group name and replaces a wildcard in a firmware filename to derive a first network path of firmware files. The telecommunications node installs the firmware files and subsequently receives an updated group name. The telecommunications node replaces the wildcard with the updated group name to derive an updated path, and obtains different firmware files from the updated path. The firmware installed on the telecommunications node is managed based on the first firmware and the different firmware.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for communication resilience in a Ring Network Topology. In some aspects, a top Ethernet node, implemented in a Ring Network Topology (“RNT”) that includes multiple additional Ethernet nodes, receives downstream traffic having a virtual local area network (“VLAN”) service address. The top Ethernet node can determine that the downstream traffic is destined for a given device serviced by a given Ethernet node, from among the multiple additional Ethernet nodes, that terminates a given Ethernet Ring Protection Switching (“ELPS”) group. The top Ethernet node can determine a given VLAN subnetwork that has been mapped to the given ELPS group, and transmit the downstream traffic through the RNT using the given VLAN subnetwork.

摘要： Methods and systems for high speed failover in a network are provided. To provide faster Type C GPON redundancy failover, the disclosure herein describes the use of G.8031 1:1 ELPS in a single ended application to ensure path integrity through the network. Single ended 1:1 ELPS means that a network device is configured with 1:1 ELPS and switches paths in the event of disruption of the working communication path without the other underlying transport entities having knowledge of either the ELPS protocol or state machine. ELPS (Ethernet Linear Protection Switching, ITU G.8031) is a standardized method for protection switching between two point-to-point paths through a network, however its application here is quite novel. During a failure on the working path, traffic will switch over to the protection path. Type C PON protection provides a fully redundant path between the OLT and the ONU (2 separate PONs).

摘要： Methods and apparatus for communicating synchronous digital signals through an asynchronous domain are disclosed. In one aspect a method includes receiving a first synchronous digital signal of a first domain, wherein the first synchronous digital signal is generated by a first device for communication to a second device; encapsulating the first synchronous digital signal of the first domain into a first asynchronous packet of a second domain; and transmitting the first asynchronous packet to an asynchronous network of the second domain.

摘要： Methods, systems, and apparatus for selecting frame loss measures are disclosed. In one aspect, a Synthetic Loss Measurement (SLM) report for a given interval for a network managed entity that includes at least two network nodes is received. A Loss Measurement Message (LMM) report for a given interval for the network managed entity is received. For the given interval and from the SLM and LMM reports, a reporting measurement for the network managed entity is selected based, at least in part, on a frame rate of data transmitted over the network managed entity during the given interval or an occurrence of a specified network event during the given interval. Frame loss information for the given interval for the network managed entity based on the selected reporting measurement is reported.

摘要： Methods and systems for resilient network communication are provided. In one aspect, a network includes multiple West NEs, spine elements, and East NEs. Each element has multiple physical communication interfaces. A working communication path connects the West NE to the East NE through a spine element. A protection communication path connects that West NE to that East NE through a different spine element. The working and protection communication paths terminate at the West NE and East NE at maintenance end points. A protection group is formed of the working communication path and the protection communication path. The protection group maintains a state designating an active path and a standby path. Maintenance groups at the spine elements monitor continuity messaging for their associated maintenance end points to determine network health. Faults between the West NEs and East NEs are detected through RDI and CCM.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for managing configurations of telecommunications nodes. In one aspect, a system includes a file server; a subtending device coupled to the file server, and a telecommunications node coupled to the subtending device. The subtending device can include one or more line cards that connect one or more telecommunications nodes to a network. The telecommunications device receives, from the file server and based on provisioning information provided by the subtending device, a first configuration file and replaces a wildcard value in the first filename with a unit-specific identifier. A unit-specific configuration file is requested from the file server, and used to configure the node. A change is detected to the configuration, and an updated unit-specific configuration file is posted to the file server using the first filename.
