Techniques are described for managing the execution of programs on multiple computing systems, such as on virtual machine nodes executing on the computing systems. A program execution service may in some situations provide the multiple computing systems and manage the program execution on behalf of multiple customers or other users, including to select appropriate computing systems to execute one or more instances of a program for a user, such as based in part on configuration information specified by the user. The described techniques may further include managing communications between multiple intercommunicating computing nodes in some situations.

Techniques are described for managing communications between multiple intercommunicating computing nodes, such as multiple virtual machine nodes hosted on one or more physical computing machines or systems. In some situations, users may specify groups of computing nodes and optionally associated access policies for use in the managing of the communications for those groups, such as by specifying which source nodes are allowed to transmit data to particular destinations nodes. In addition, determinations of whether initiated data transmissions from source nodes to destination nodes are authorized may be dynamically negotiated for and recorded for later use in automatically authorizing future such data transmissions without negotiation.

An information processing apparatus includes a processor. The processor assigns priority levels to respective logics arranged in a chain graph. Each logic is activated by an input event to generate an output event. The processor allocates tokens to the logics based on the priority levels. The processor estimates, for each of the logics, a total number of generated output events to obtain an expected amount of tokens corresponding to the total number. The processor compares, for each of the logics, the expected amount of tokens to an amount of the allocated tokens to determine whether each of the logics has a surplus or a shortage in the allocated tokens. The processor adjusts a frequency of activating each of logics having the shortage. The processor calculates a total amount of the surplus. The processor reallocates the total amount of the surplus to the logics having the shortage.

Methods, non-transitory machine readable media, and network stack analysis devices that generate optimized preferred provider organization (PPO) network stacks are disclosed. With this technology, electronic transactions are applied to each of a first plurality of network stacks to determine a cost reduction value for each of the first network stacks. Each of the first network stacks includes an ordered subset of networks. The first network stacks are resampled based on the determined cost reduction values. A determination is made when one or more convergence criteria are met by the resampled first network stacks. When the determination indicates that the convergence criteria are not met by the resampled first network stacks, one or more of the first network stacks are modified based on genetic crossover or mutation operation(s) to generate a second plurality of network stacks. The application, resampling, and determination are then repeated for the second network stacks.

Techniques are described for managing communications between multiple intercommunicating computing nodes, such as multiple virtual machine nodes hosted on one or more physical computing machines or systems. In some situations, users may specify groups of computing nodes and optionally associated access policies for use in the managing of the communications for those groups, such as by specifying which source nodes are allowed to transmit data to particular destinations nodes. In addition, determinations of whether initiated data transmissions from source nodes to destination nodes are authorized may be dynamically negotiated for and recorded for later use in automatically authorizing future such data transmissions without negotiation.

Methods for implementing different pricing configurations by a server system are disclosed. The server system provides an application programming interface (API) for one or more network operators and receives, from a network operator via the API, a first request for a pricing configuration for network access for one or more internet protocol (IP) addresses hosted by the network operator. The server system retrieves the pricing configuration and provides a response to the first request to the network operator via the API that includes the pricing configuration.
