The network congestion scenario identifier is an identifier indicating a scenario in which network congestion occurs in a process in which the transmit end transmits data to a receive end, and the transmit end and the receive end are any two hosts in the plurality of hosts. Then, the transmit end adjusts a data sending rate of the transmit end based on the network congestion scenario identifier.

Abstract: Systems and methods are described herein for novel uses and/or improvements for autonomous configuration of network applications on a network. When a request is received for adding a new application to the network, the system may analyze the request and identify which network devices need a change in configuration. The system may also determine, based on the request, what type of changes are needed. The system may then generate one or more commands for each identified network device and transmit those commands to each device for performing automatic network configuration for the application.

Abstract: Techniques are provided for predicting data for precaching and/or recaching at a computer cache of a computer environment. Based on a detected login event of a user, a precache API request can be generated for a type of API data request most often utilized by the user over a predetermined time period. An API gateway may use the precache API request to obtain a corresponding precache API response from a microservice. The precache API response may be stored together at an API gateway cache. Subsequently, when information from an API call substantially matches a cache key corresponding to the precache API response, the precache API response can be provided to the user instead of obtaining the response from the microservice. Additionally, the precache API request may include a recache value that can be used to iteratively obtain up-to-date precache API responses from the microservice.

The mesh network configuration is sent to at least the second device by the first node device based on the mesh node signature list. The first node device routes network traffic data to at least the second device based on the mesh network configuration.

Abstract: A media stream is transmitted from a server device to a client device. The client device (10) transmits set-up request messages (43a), discovery messages (44b) and a play command message (45a). The server receives versions of the set-up request messages 43b), the discovery message (44b) and the play message (45b) with matching identifier in the payloads if the messages. The server device (12) receives the discovery messages (44b) on a predetermined port and stores information recording that the discovery messages (44b) have been received, at least when no corresponding set-up request message 43b has been received before. The server device (12) compares the identifiers from the received set up request message (43b) and the discovery message (44b) according to the information recording reception, at least when the discovery message (44b) has been received before the set-up request message (43b).

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: A media stream sending method provides a live media stream for a client that enters a live broadcast room. A proxy server receives, from a first client, a first live broadcast room request message for requesting to enter the live broadcast room; the proxy server determines a role of the first client based on the first live broadcast room request message; and if the role of the first client is a slave user, the proxy server sends a first live media stream cached in the proxy server to the first client, where the first live media stream is a media stream that is sent by a media server to a second client through the proxy server, and a role of the second client is a master user.
