Abstract: A scheduling platform for scheduling serverless application tasks in persistent memory (PMEM) is provided. A profiler receives application requests from processes of serverless applications. The profiler categorizes the processes as persistent or non-persistent based on the application requests. A read/write batcher creates batches of the persistent requests including the read requests and write requests and assigns the batches to persistent memory banks. A scheduler creates a schedule of the batches to the persistent memory banks in a manner enabling optimization of job completion time.

Abstract: Implementations of the present disclosure relate to resource unit (RU) assignment to combat frequency selective fading. A method comprises determining, at an access point (AP), a plurality of channel qualities of a plurality of resource units (RUs) for a client. The plurality of RUs are configured to be available for communications with a plurality of clients comprising the client. The method further comprises determining, from the plurality of RUs, a target RU for the client based at least in part on the plurality of channel qualities. The target RU is to be used by the client for a following transmission with the AP. A target RU with good channel quality will be assigned to the client, thus the transmission and overall system performance will be enhanced.

Abstract: Systems and methods are provided for discoverability detection of network services. The present disclosure provides for a cloud-based network insight server that collects performance information of a network and a network agent, communicating with the cloud-based network insight server, that monitors discoverability of network services hosted by devices on the network. The network agent receives configuration information from the cloud-based network insight server and transmits discoverability states of the devices to the cloud-based network insight server based on executing a service discovery process through an access point on the network.

Abstract: Examples of performing selective Fine Timing Measurement (FTM) are described. For an FTM scan cycle, a first AP (i.e., an initiator) may determine scanning parameter values of a plurality of second APs (i.e., potential responders) based on previously performed FTM scans. The first AP may determine weights of the plurality of second APs based on the scanning parameter values and select a set of target APs based on the weights. The first AP may then scan the set of target APs for the FTM scan so that the rest of the plurality of second APs are relieved from participating in the FTM scan thereby reducing the performance impact on the rest of the plurality of second APs. After the FTM scan cycle is completed, the first AP may update the weights and select another set of target APs based on the updated weights to perform another FTM scan cycle.

Abstract: One aspect can provide a system and method for configuring a plurality of branch gateway (BGW) devices coupled to a virtual private network concentrator (VPNC). The VPNC negotiates with a respective BGW device a transmission-bandwidth contract; receives, from the BGW device, a request for additional transmission bandwidth; analyzes traffic patterns to identify one or more BGW devices with unused bandwidth; allocates the requested additional transmission bandwidth to the respective BGW device by reducing transmission bandwidth allocated to the identified one or more BGW devices; and transmits contract-update notifications to the BGW devices to allow each BGW device to update a corresponding transmission-bandwidth contract, which comprises increasing the upper bandwidth limit at the respective BGW device while reducing the upper bandwidth limit at the identified BGW devices. In response to expiration of a timer, the VPNC revokes the additional transmission bandwidth allocated to the respective branch gateway device.

Abstract: An apparatus facilitating efficient key refresh in a node is provided. During operation, the apparatus can determine a collective operation initiated by the node. The node can include a processor and can be in a distributed system comprising a plurality of nodes. The collective operation can be performed by a subset of the plurality of nodes in conjunction with each other. The apparatus can generate a new key based on a previous key maintained at the apparatus. Here, a respective key can be used for encrypting an inter-node packet in the distributed system. The apparatus can maintain the new and previous keys for the duration of the collective operation. Either of the new and previous keys can be used for decrypting messages received at the apparatus from other nodes of the distributed system. Upon determining a threshold point of the collective operation, the apparatus can discard the previous key.

Abstract: A piece of networking equipment facilitating efficient congestion management is provided. During operation, the equipment can receive, via a network, a plurality of packets that include portions of a data segment sent from a sender device to a receiver device. The equipment can identify, among the plurality of packets, one or more payload packets comprising payload of the data segment, and at least a header packet comprising header information of the data segment and a header-packet indicator. The equipment can determine whether congestion is detected at the receiver device based on a number of sender devices sending packets to the receiver device via the equipment. Upon determining congestion at the receiver device, the equipment can perform flow trimming by forwarding the header packet to the receiver device and dropping a subset of the one or more payload packets.

Abstract: Some examples relate to firmware updates. In an example, a first core system determines firmware updates to be installed on the first core system and auxiliary systems of a data center. The first core system sends firmware update package generation instructions to a cloud infrastructure comprising data center firmware updates. The first core system downloads a firmware update package from the cloud infrastructure. The first core system updates firmware of the first core system, based on one or more firmware updates in the firmware update package. The first core system receives a request for a specific firmware update from an auxiliary system. Based on the request received from the auxiliary system, the first core system identifies the specific firmware update for the auxiliary system from the firmware update package. The first core system provides the specific firmware update to the auxiliary system.

Abstract: Implementations disclosed herein provide for devices and methods for obtaining parity time (PT) symmetric directional couplers through improved phase tuning, along with separate optical gain and optical loss tuning. The present disclosure integrates phase tuning and optical gain/loss tuning structures into waveguides of directional couplers disclosed herein. In some examples, directional couplers disclosed herein integrate one or more hybrid metal-oxide-semiconductor capacitors (MOSCAPs) formed by a dielectric layer between two semiconductor layers that provide for phase tuning via plasma dispersion and/or carrier accumulation depending on voltage bias polarity, and one or more optically active medium that provide for optical gain or loss tuning depending on voltage bias polarity.

Abstract: Examples provide new roaming test systems for network deployments that can be implemented remotely using a single physical AP. Examples achieve this elegant system by emulating a physical network deployment using a group of VAPs provisioned on the single physical AP (a VAP may refer to a logical or a virtual AP instance on a physical AP). Each VAP of CAP group may be configured to represent a physical AP of the physical network deployment (such a network deployment may be a prospective deployment or, an actual/set-up deployment). Examples can simulate/emulate a wireless client physically moving between physical APs of the network deployment by varying transmission power associated with each VAP as a function of time in a manner that mirrors how a wireless client would perceive transmission power varying for physical APs of the network deployment (represented by the VAPs) as the wireless client moves across the geographical site of the network deployment.
