A system and method of forming proxy server pools is provided. The method comprises several steps, such as requesting a pool to execute the user's request and retrieving an initial group. The system checks the service history of an initial group, including whether any of the proxy servers in an initial group are exclusive to existing pools. The exclusive proxy servers in an initial group with eligible proxy servers are replaced when needed and new proxy server pools are formed. The system also records the service history of proxy servers and pools before and after the pools are created. The method can also involve predicting the pool health in relation with the thresholds foreseen and replacing the proxy servers below the threshold.

Novel tools and techniques are provided for implementing intent-based orchestration using network parsimony trees. In various embodiments, in response to receiving a request for network services that comprises desired characteristics and performance parameters for the requested network services without information regarding specific hardware, hardware type, location, or network, a computing system might generate a request-based parsimony tree based on the desired characteristics and performance parameters. The computing system might access, from a datastore, a plurality of network-based parsimony trees that are each generated based on measured network metrics, might compare the request-based parsimony tree with each of one or more network-based parsimony trees to determine a fitness score for each network-based parsimony tree, and might identify a best-fit network-based parsimony tree based on the fitness scores. The computing system might identify and might allocate network resources based on the identified best-fit network-based parsimony tree, for providing the requested network services.

A method for communication session management by a session controller is described. Usage data associated with a video communication session is received for data stream handlers of a first network topology, which handle data streams of the video communication session at a first time. The first network topology includes a plurality of client devices and at least a first media server. A second network topology is determined based on the usage data to handle the data streams when a network parameter and/or an application parameter reaches a corresponding update threshold. Data stream handlers of the second network topology include at least a second media server. The data stream handlers of the second network topology are configured to handle the data streams at a second time, including instructing the first media server to offload at least some of the data streams to the second media server.

Techniques for dynamically cloning application infrastructures are provided. In one embodiment, a computer system can monitor one or more metrics pertaining to an infrastructure for an application at a first site. If the one or more metrics exceed or fall below one or more corresponding thresholds, the computer system can clone the infrastructure at a second site distinct from the first site, thereby enabling the application to be hosted at the second site.

The present disclosure discloses a method for preheating a resource file, and a central management system, and relates to the field of network communication technology. The method includes: according to historical bandwidth data of a target intermediate node, determining a bandwidth off-peak period of the target intermediate node; during the bandwidth off-peak period of the target intermediate node, pre-caching the resource file on an edge node corresponding to the target intermediate node.

A logical grouping of subgroups of server clusters forms a failover super-cluster. A logical grouping of groups of servers provides high availability by, upon failure of an entire group (site), failing over an entire subgroup to a different subgroup. Yet within each subgroup local failovers continue to maintain application high availability during instances in which the site remains operational.

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.
