A network arrangement that employs a cache having copies distributed among a plurality of different locations. The cache stores state information for a session with any of the server devices so that it is accessible to at least one other server device. Using this arrangement, when a client device switches from a connection with a first server device to a connection with a second server device, the second server device can retrieve state information from the cache corresponding to the session between the client device and the first server device. The second server device can then use the retrieved state information to accept a session with the client device.

A method for generating network function (NF) set load information aware NF discovery responses includes, at an NF repository function (NRF), receiving NFUpdate messages from producer NF instances. The method further includes collecting or generating, from the NFUpdate messages, NF set load information for NF sets of which the producer NF instances are members. The method further includes receiving, from a consumer NF, an NF discovery request. The method further includes generating, using query parameters in the NF discovery request, an NF discovery response including NF profiles of producer NF instances corresponding to the query and, including, in the NF discovery response, NF set load information for NF sets of producer NF instances whose NF profiles are included in the NF discovery response. The method further includes forwarding the NF discovery response including the NF set load information to the consumer NF.

Examples of a method for brokering remote servers are described herein. In some examples, performance data is received from a plurality of remote servers, where the performance data indicates rendering performance of a foreground application executed by at least one of the remote servers and streamed from at least one of the remote servers over a remote desktop connection. An indication of a selected application is received from a client. The client is directed to at least one of the remote servers based on the performance data and the selected application.

In an example embodiment, a specialized architecture is utilized in conjunction with a message broker to enable asynchronous communications. The specialized architecture provides central components within each data center to enable the communication, and also is able to segregate functionality across different microservice landscapes. A message broker alone may not be sharable across data centers for various technical reasons, such as security concerns, latency, or other technical constraints. Topic names may be utilized by the message broker to ensure delivery of the message to the correct microservice in the other data center.

Network traffic flows can be processed by routers, switches, or service nodes. Service nodes may be ASICs that can provide the functionality of a switch or a router. Service nodes can be configured in a circular replication chain, thereby providing benefits such as high reliability. The service nodes can implement methods that include receiving a first packet that includes a source address in a source address field and that includes a destination address in a destination address field. The first packet can be routed to a selected service node that is in the replication chain that includes a plurality of service nodes that are configured for chain replication of a service state information. A service node configured for NAT or some other service can use the first packet to produce a translated packet that can be transmitted toward a destination indicated by the destination address.

Techniques described herein relate to a method for managing workflows. The method may include obtaining, from a client, by a registration manager associated with accelerator pools, a request to perform a portion of a workflow using accelerators; identifying a minimum quantity and a maximum quantity of accelerators associated with the request; identifying a storage to store data associated with the portion of the workflow; identifying an accelerator pool of the accelerator pools that includes at least the maximum quantity of accelerators; establishing a connection between the client, the storage, and accelerators of the accelerator pool to perform the portion of the workflow; and initiating the performance of the portion of the workflow using the storage, the client, and the accelerators of the accelerator pool.

The disclosure provides an approach for seamless hand-off of data traffic in public cloud environments. Techniques are provided for activating an edge services gateway (ESG) virtual computing instance (VCI) on a new host. Prior to activating the ESG VCI on the new host, an underlay routing table is reprogrammed to associate a first IP address of a first tunnel endpoint (TEP) with a first network interface of an old host and to associate a second IP address of a second TEP with a second network interface of the new host. The routing table associates a third IP address of the ESG VCI with the first network interface. After activating the ESG VCI, a packet having as a destination address the third IP address is received at the first network interface and is encapsulated, by the first TEP, with an outer header having as a destination address the second IP address.

This disclosure describes techniques and mechanisms for providing hybrid cloud services for enterprise fabric. The techniques include enhancing an on-demand protocol (e.g., such as LISP) and allowing simplified security and/or firewall service insertion for datacenter servers providing those services. Accordingly, the techniques described herein provide hybrid cloud services that work in disaggregated, distributed, and consistent way, while avoiding complex datacenter network devices (e.g., such running overlay on TOR), replacing and moving the functionality to on demand protocol enabled servers, which intelligently receive the required mappings as well as registers and publishes the service information to intelligently interact with the network.

The present disclosure relates to systems, non-transitory computer-readable media, and methods for improving the efficiency and flexibility of implementing computer devices by intelligently generating a metric blocklist based on predicted utilization of digital metrics and deploying the metric blocklist at one or more computing devices to limit digital metric requests to distributed databases. In particular, in one or more embodiments, the disclosed systems monitor historical digital metric utilization and apply a prediction model to generate a metric blocklist of digital metrics that are not likely to be utilized by one or more metric requesting devices of a distributed computing system. The disclosed systems can deploy the metric blocklist to computing devices of a distributed computing system to efficiently limit digital requests, processing resources, bandwidth consumption, and storage load with regard to utilization of metric storage devices (e.g., time-series databases).

A method for exchanging data between several field devices includes: implementing an exchange of data between a requesting field device and a responding field device using a publish-subscribe principle; subscribing the responding field device to request messages whose message titles include a specification of a field device identifier of the responding field device; subscribing the requesting field device to response messages whose message titles include a request identifier known to the requesting field device; the requesting field device publishing a request message to a data broker, the message title of the request message including the request identifier and the specification; the responding field device receiving the request message, evaluating the request message, and publishing a corresponding response message to the data broker, the message title of the response message including the request identifier; and the requesting field device receiving the response message based on the subscription to the response message.
