    摘要： Techniques are disclosed for load balancing based on call length in networks such as those networks handling telephony applications. By way of example, one method for directing requests associated with calls to servers in a system comprised of a network routing calls between at least one caller and at least one receiver wherein the network comprises a load balancer sending requests to a plurality of servers comprises the following steps. A first request of a call is received. A server s1 is selected to receive the request based on an estimated duration of the call. Another method for directing requests associated with calls to servers in a system comprised of a network routing calls between at least one caller and at least one receiver wherein the network comprises a load balancer sending requests to a plurality of servers comprises the following steps. Information is maintained regarding load assigned to a plurality of servers. A first request of a call is received. A server s1 is selected to receive the request based on the maintained information. The request is sent to server s1. The information regarding load is updated based on an estimated length of the call.

    摘要： A management system and method for a virtualized environment includes a computer entity having a usage limitation based on an entitlement. A resource manager, using a processor and programmed on and executed from a memory storage device, is configured to manage resources in a virtualized environment. An entitlement-usage module is coupled to the resource manager and is configured to track entitlement-related constraints in accordance with changes in the virtualized environment to permit the resource manager to make allocation decisions which include the entitlement-related constraints to ensure that the usage limitation is met for the computer entity.

    摘要： Provides control of the workload, flow control, and concurrency control of a computer system through the use of only external performance monitors. Data collected by external performance monitors are used to build a simple, black box model of the computer system, comprising two resources: a virtual bottleneck resource and a delay resource representing all non-bottleneck resources combined. The service times of the two resource types are two parameters of the black box model. The two parameters are evaluated based on historical data collected by the external performance monitors. The workload capacity that avoids saturation of the bottleneck resource is then determined and used as a control variable by a flow controller to limit the workload on the computer system. The workload may include a mix of traffic classes. In such a case, data is collected, parameters are evaluated and control variables are determined for each of the traffic classes.

    摘要： Techniques are disclosed for load balancing in networks such as those networks handling telephony applications. By way of example, a method for directing requests associated with calls to servers in a system comprised of a network routing calls between a plurality of nodes wherein a node participates in a call as a caller or a receiver and wherein a load balancer sends requests associated with calls to a plurality of servers comprises the following steps. A request associated with a node belonging to a group including a plurality of nodes is received. A server is selected to receive the request. A subsequent request is received. A determination is made whether or not the subsequent request is associated with a node belonging to the group. The subsequent request is sent to the server based on determining that the subsequent request is associated with a node belonging to the group. By way of another example, a method for balancing requests among servers in a client server environment wherein a load balancer sends requests associated with a client to a plurality of servers comprises the following steps. Information is maintained regarding a weighted number of requests assigned to each server. The load balancer receives a request from a client. A server s1 is selected to receive the request by examining the maintained information and identifying a server with a least weighted number of requests assigned thereto. The load balancer sends the request to server s1 and increments a weighted number of requests assigned to server s1 in the maintained information. In response to receiving a notification from server s1 that the request has completed, a weighted number of requests assigned to server s1 is decremented in the maintained information.
