IPC Code(s): G02B6/02
CPC Code(s): G02B6/02076
Abstract: embodiments herein describe an electro-optic waveguide having a multi-mode multi-pass phase shifter (mmps) tuner, one or more two-mode bragg gratings, and one or more selective evanescent couplers. an input signal having a fundamental mode is reflected by the one or more bragg gratings and tuned by the mmps tuner. in this manner, the electro-optic waveguide isolates the higher order modes of the input signal. the one or more selective evanescent couplers capture an output signal having the highest order mode and reduces the mode of the output signal to the fundamental mode.

Abstract: techniques for combining the functionality of fabric interconnects and switches (e.g., top-of-rack (tor) switches) into one network entity, thereby reducing the number of devices in a fabric and complexity of communications in the fabric. by collapsing fi and tor switch functionality into one network entity, server traffic may be directly forwarded by the tor switch and an entire tier is now eliminated from the topology hierarchy which may improve the control, data, and management plane. further, this disclosure describes techniques for dynamically managing the number of gateway proxies running on one or more computer clusters based on a number of managed switch domains.

Abstract: techniques for mitigating network failures (e.g., sla violations, service degradations, network outages, etc.) based on output(s) from a predictive network system. the techniques may include determining that a failure is predicted to occur in a network and determining a correlation between the failure and a previous failure that occurred in the network. in examples, the correlation may be determined using a machine-learned model. the techniques may also include determining, based at least in part on the correlation, a condition contributing to the failure. in this way, prior to occurrence of the failure, a parameter associated with the network may be altered based at least in part on the condition to mitigate or otherwise prevent the failure.

Abstract: devices, systems, methods, and processes for sustainably deploying serverless functions across the globe are described herein. often, when considering sustainability options for cloud-based service providers that can accept and operate serverless functions from various sources, the power source type can be considered. in many cases, solar-powered power sources can be desired, but is only available during the day. thus, it may be desirable to consider where the location of a cloud-based service provider is located in relation to the daylight time. thus, various data related to the power being utilized to power the cloud-based service provider location can be determined and utilized when comparing potential locations to deploy serverless functions. in some cases, a sustainability score can be generated based on this sustainability data and a sustainability profile that can be compared against other locations to determine the most suitable cloud-based service provider to deploy the serverless function onto.

CPC Code(s): H04L47/2483
Abstract: a port extender provides individual flow control for ports multiplexed from a network device. the port extender is configured to multiplex a network device port across the front panel ports on the port extender. the port extender also determines that an input buffer for the network device port is overloaded, and generates a priority-based flow control (pfc) frame identifying that the network device port is congested. the port extender sends the pfc frame via the network device port to the network device. the pfc frame causes the network device coupled to the network device port to discontinue sending data for transmission from the plurality of ports on the port extender.

IPC Code(s): H04L47/36
CPC Code(s): H04L47/36
Abstract: techniques are described for detecting a change in path maximum transfer unit (pmtu) in a network and initiating a pmtu discovery process. a bidirectional forwarding detection (bfd) data packet is generated having enhanced headers configured to record a largest packet sent value and a largest packet received value. the bfd data packet is sent from a first network device (such as a first router) to a second network device (such as a second router). a largest packet sent value and a largest packet received value are each recorded in the bfd data packet. if the largest data packet sent value is larger than the largest data packet received value, then a determination can be made that a path change has resulted in a reduction in pmtu which has resulted in either a data packet being fragmented, a data packet being dropped or both. a pmtu discovery can then be performed.

CPC Code(s): H04L47/822
Abstract: devices, systems, methods, and processes for sustainably operating a plurality of network planes via de-energization and re-energization is described herein. in many network configurations, a plurality of planes exist that allow for more modular connections in a network fabric. often, these planes are configured such that each plane is not directly connected to another plane. because of this, various embodiments described herein can evaluate network conditions and determine if there are conditions suitable to de-energize a plane by either directing the plane to enter a lower-power mode, by shutting off the plane, or disconnecting the available power. this de-energization period can be for a period of time or can occur until a triggering event is detected that indicates that the plane should be re-energized. these determinations can be done based on current traffic trends or historical conditions. they may also be heuristic-based or generated via one or more machine-learning processes.
