Successive approximation register analog to digital converter based phase-locked loop with programmable range
13 Apr 21
Described herein are apparatus and methods for a successive approximation register (SAR) analog-to-digital (ADC) based phase-locked loop (PLL) with programmable range.
Optical protection devices having passive splitter/couplers and built-in interrupters
13 Apr 21
Optical protection devices are provided for protecting client equipment in an optical communication system.
Adaptive network slicing via overlaying decomposition and inheritance
8 Apr 21
Systems and methods include provisioning a default slice having a default subdomain corresponding to a set of resources that are any of physical and virtual components in a network; decomposing the default subdomain into a first set of one or more subdomains, wherein collectively the first set of one or more subdomains include all of the set of resources; provisioning one or more application slices as children from the default slice that inherit capabilities of the default slice; and assigning one or more subdomains from the first set of the one or more subdomains to the respective one or more application slices.
Pre-populating media access control (MAC) address tables in networks where flooding of MAC addresses is blocked
6 Apr 21
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.
Data structures representing models of networking equipment and methods of network management employing thereof
6 Apr 21
A processor-implemented method implemented to model devices in a network utilizing an assembly providing an arbitrary model includes utilizing one or more first models to represent relationships between devices in the network for control and management thereof, wherein the one or more first models are implemented in an associated database of one or more databases each with an associated schema; defining an assembly to implement the arbitrary model different from the first model, wherein the assembly comprises pointers to data instances in the one or more databases; and utilizing the arbitrary model for control and management of the devices in the network, wherein the control and management via the arbitrary model updates the data instances in the one or more databases representing the first model.
