A processor of a network computing device may determine a latency metric and a transaction volume metric for a network application, determine an autoscaling cost based on the determined latency metric and transaction volume metric, allocate to the network application computing resources based on the determined autoscaling cost, and provide the allocated computing resources to the network application.

Abstract: Techniques are described for enabling resources within a cloud computing system to interact with each other. In certain embodiments, a base identifier assigned to a first resource is extended by mapping the base identifier onto a second identifier assigned to a logical resource that is built upon the first resource. This allows the first resource to have two identities, one identity indicating what the first resource is (e.g., a particular compute instance) and another identity indicating the purpose of the first resource (e.g., operating as a database for a particular tenancy). Consequently, the first resource may be provided with access privileges different from those associated with the base identifier. For example, the first resource may access another resource in the tenancy using the second identifier, but may have no access to the other resource using the base identifier.

The method determines whether the route conditions are satisfied. The method performs the actions specified in the BGP wide community container on the multiple route attributes when the one or more route conditions are satisfied.

Further, the techniques may include using short timestamps to determine delay measurements associated with sending a packet through a network. In various examples, the techniques described above and herein may be used with each other to optimize network path tracing and delay measurement techniques.

Abstract: Systems and methods are disclosed herein for media quality selection of media assets based on internet service provider data usage limits. One disclosed technique herein discusses receiving a data usage limit from an internet service provider. The data usage limit includes maximum data usage for particular user account data. A media asset is selected from a media streaming server that includes a plurality of qualities having respective data sizes (e.g., for video quality—4K, 1080p, etc.) A determination is made whether a selected data size from a selected quality of the plurality of qualities of the selected media asset exceeds remaining data of the received data usage limit. If so, a request is transmitted to the to the media streaming server to retrieve the selected media asset with a quality having a data size smaller than the respective data size.

Abstract: A control server receives probe data from a plurality of data centers indicating measured latencies with a first IP address associated with an origin server. The control server sums the measured latencies of a first data center having a lowest measured latency and a second data center. When the sum is below a threshold value, the control server determines the IP address to be an anycast IP address and selects a proper subset of the plurality of data centers as proxying data centers for other data centers in the plurality of data centers. When the sum is not below the threshold value, the control server determines the IP address to not be an anycast IP address and selects the first data center having the lowest measure latencies as the proxying data center for other data centers in the plurality of data centers.

Abstract: A device may provide path data identifying a primary path and one or more alternate paths for segment routing traffic in the network, and may receive performance data indicating a performance degradation in the primary path. The device may determine that the performance data satisfies a first threshold, and may request, based on the performance data satisfying the first threshold, alternate path performance data. The device may receive the alternate path performance data based on the request, and may compare the alternate path performance data for the one or more alternate paths. The device may select a particular alternate path, of the one or more alternate paths, based on comparing the alternate path performance data for the one or more alternate paths, and may trigger, based on the performance data satisfying a second threshold, a failover of the traffic from the primary path and to the particular alternate path.

Abstract: Systems, devices, and methods are provided for transmitting and retransmitting data. A first message transmitted by a sender computing entity to a receiver computing entity over a first port may exercise a first network path whereas a second message transmitted over a second port may exercise a second network path. A system (e.g., sender computing entity) may determine network reliability metrics for a plurality of network paths. If a system detects data loss (e.g., packet loss) on a first port, a second port may be selected based on network reliability metrics for retransmission of the lost data. A port may for example, be selected for retransmission based on the following criteria: (1) the port has the longest consecutive duration without packet loss and (2) the port has received an acknowledgement for a packet that was sent more recently than the initial transmission of the lost packet.

Abstract: A method for aggregating and regulating messages in a network that has a plurality of pairs of nodes and two transmitting/receiving devices communicating via a bidirectional channel. The method is implemented by each of the transmitting/receiving devices. Each received message may be segmented into packets of a predefined size, and each packet may be allocated to a queue that depends on the origin, the destination, and the priority of the message. One or more frames may then be created, and packets of the queues may be inserted into the frames. Frames may then be sent via the bidirectional channel over a predefined time interval, the number of frames sent over the time interval being dependent on the maximum throughput of the channel and on the useful throughput in each of the transport directions of the channel.
