Solutions for enabling lower privilege users (e.g., applications, virtualized computing environment applications such as virtual machines or containers) to perform requests for service (e.g., remote procedure calls) that require higher privilege include: receiving, by a relay service executing at a first privilege level, from an application executing at a lower privilege level, a received request for service. The first privilege level is sufficient for the request, however, the application's privilege level is insufficient. The relay service determines whether the application is authorized to perform the request by comparing the application identity and the request with privilege exception information (e.g., a list of application identities and corresponding requests that are subject to privilege exception). If the application's request is authorized, the relay service relays the request (e.g., as a hypercall) to a destination service at the relay's service own privilege level and then relays the received response back to the application.

Authorizing lower privilege users to invoke privileged calls

Data transfer rates on a network are controlled in conjunction with TCP/IP protocols by limiting the available space in a receive buffer located on the receiver. Limits are generated by either moderating the rate that data is removed from the receive buffer or changing the receive buffer's size. Transfer rates are reduced to decrease the impact large transfers have on other network traffic and to reduce the total number of lost data packets. Reduced rates and priorities can be managed by scheduling systems.

System and method for controlling data transfer rates on a network

A system and method for scheduling transfers of data through a network, the system comprising a transfer module at each node in the network, the transfer module being configured to schedule data transfers according to available resources at each node. In one embodiment, the transfer module includes a scheduling module, a routing module, and an execution module. The scheduling module at each node evaluates a single hop request in view of objectives, such as a deadline, and the available resources at that node, for example transmit bandwidth, receive bandwidth, and storage space, all of which may change as a function of time.
