The present disclosure generally relates to managing redundancy capacity in a region having a plurality of active availability zones. For individual regions, a load balancing component can implement a redundancy validation routine that includes a non-uniform distribution of load for a set of active availability zones such that one availability zone receives an increase in traffic corresponding to the likely increase that would be experienced in response to an availability zone failure. The network service can perform automatic remediation.

In response to receipt of a notification from a third service, a scaling policy specified by a customer of a computing resource service provider to be associated with the notification is obtained, with the scaling policy including a set of parameters that includes an identity of a resource of a second service of the computing resource service provider. As a result of processing the scaling policy in accordance with the set of parameters, a request is submitted to a second service to scale the resource, and output is provided that indicates whether the scaling request has been fulfilled.

Embodiments of the present invention address deficiencies of the art in respect to audio stream management in an audio conferencing server and provide a method, system and computer program product for balancing audio server loadability and audio server scalability based upon monitored resource consumption. In an embodiment of the invention, a method for balancing audio server loadability and audio server scalability based upon monitored resource consumption can be provided. The method can include monitoring computing conditions in an audio conferencing server receiving encoded audio packets from coupled Internet Protocol (IP) audio clients and routing the encoded audio packets as audio streams to the IP audio clients, and responsive to detecting deteriorating computing conditions in the audio conferencing server, reducing a number of the audio streams forwarded to the IP audio clients by the audio conferencing server.

The invention relates to an architecture that facilitates assigning and load balancing of rooms assigned to at least one server. In an illustrative embodiment, the method comprises retrieving a current number of assigned rooms to each server, retrieving a current number of unassigned rooms, determining a current server weight for each of at least a subset of the at least one server within the at least two distribution groups, determining a total server weight, and calculating the number of rooms to load for at least a given one of the at least one server based at least in part on the number of unassigned rooms, total server weight, and current server weight of the given one of the at least one server.

A time-based adjustable load balancing method and device is provided, which, by acquiring and recording at least one timed task including an execution time period and a load balancing method to be executed in the execution time period, implements creation of different load balancing methods based on definition of multiple time periods, and executes a corresponding load balancing method in an execution time period. Further, it is determined whether a current time enters an execution time period of one timed task, and if yes, the load balancing method corresponding to the timed task is acquired, and load balancing between multiple servers is processed based on the corresponding load balancing method, until the execution time period corresponding to the timed task ends, thereby implementing flexible configuration of a user. The load balancing method meeting the user requirement is flexibly applied to complicated user scenarios, thereby enhancing applicability of the load balancing.

A network element in a data center includes a plurality of servers and a switch. The switch includes a plurality of physical ports, a packet-forwarding table, and an application program interface (API) for modifying a packet-forwarding behavior of the switch. The packet-forwarding table determines a packet-traffic distribution across the servers by mapping packet traffic arriving at the switch to the plurality of ports. Each port of the plurality of physical ports is in communication with one of the servers. The network element further includes means for determining in real time the packet-traffic distribution across the servers, and means for dynamically changing the packet-traffic distribution across the servers in response to the determined packet-traffic distribution by modifying the packet-forwarding behavior of the switch through the API of the switch.

A system includes a policy repository configured to store a plurality of plurality of media-centric policies. A media policy decision point receives media session data corresponding to one of the plurality of media sessions; determines a plurality of media-specific and non-media specific attributes, based on the media session data; and evaluates a plurality of media-centric policies to determine a proper subset of the plurality of media-centric policies that apply to the one of the plurality of media sessions. A media policy enforcement point enforces the proper subset of the plurality of media-centric policies to control the one of the plurality of media sessions.

An overlay content distribution network provides a consistent interface to enable the storage and retrieval of digital content at multiple storage providers (210). An allocator component (140) instantiates and destroys location and/or provider specific agent processes (240) which transfer digital content to and from the storage providers (210). Encoding agent processes (250) are geographically located near the storage providers (210) at which the content is to be stored. Content may be stored in a manner which guarantees content availability, each storage provider (210) being periodically probed by a Quality of Service (QoS) probes distributed within the network.

Disclosed is a system for servers to redirect client requests to other servers in order to distribute client traffic among the servers. A client is assigned to a server although the client may be unaware of that assignment. When the client accesses a server, a server possibly identified to the client by a name service, the server checks the client's assignment. If the client is not assigned to this server, then in some scenarios this server redirects the client to its assigned server. The client responds by sending its request to the assigned server. In other scenarios, the first server accessed by the client proxies the client's traffic to the assigned server. A database is kept of client-to-server assignments. If the present load distribution is less than ideal (e.g., clients are assigned to an unavailable server), then the assignment database is updated to reflect how the load should be distributed.

Techniques for dynamic configuration of a load balancer in a virtual network environment are described. In one example embodiment, load balancing rules are configured using virtual machine (VM) inventory objects. The configured load balancing rules are then transformed by replacing the VM inventory objects in the configured load balancing rules with associated Internet protocol (IP) addresses using an IP address management (IPAM) table or a network address translation (NAT) table. The transformed load balancing rules are then sent to the load balancer for load balancing network traffic between a plurality of VMs running on one or more host computing systems in one or more computing networks.
