摘要： A system and a method dynamically adjusts the quality of service guarantees for virtual servers based upon the resource demands experienced by the virtual servers. Virtual server resource denials are monitored to determine if a virtual server is overloaded based upon the resource denials. Virtual server resources are modified dynamically to respond to the changing resource requirements of each virtual server. Occasionally, a physical host housing a virtual server may not have additional resources to allocate to a virtual server requiring increased resources. In this instance, a virtual server hosted by the overloaded physical host is transferred to another physical host with sufficient resources.

摘要： Communications between network devices on a logical subnet are restricted between devices authorized to communicate with each other, even though other network devices may be present on the subnet. When a network device receives a request to provide it L2 address to a requesting network device, it responds with its L2 address only if the requesting device is authorized to request L2 address. Optionally, a network device only transmits requests for the L2 addresses of other devices if it authorized to do so. The information describing authorized devices maybe store as list of L2 and L3 addresses, which list may be loaded by each network device when starting up. Preferably, authorized devices include routers on the device's logical subnet, to allow the routers to communicate with, and route packets to, the network devices.

摘要： An I/O multiplexing operation involving a cross-domain file descriptor set is intercepted. The cross-domain set is divided into a first subset corresponding to a first file type and a second subset corresponding to a second file type. System calls are initiated in parallel for performing separate I/O multiplexing operations on the first and second subsets of file descriptors. In response to one of the parallel system calls identifying at least one file descriptor ready for communication, the other parallel system call is unblocked. Sets of file descriptors identified as ready for communication by the parallel system calls are combined and returned to a calling process.

摘要： A method facilitates providing appropriate quality of service guarantees to a plurality of virtual hosts on a single physical host computer. A server application program and its child processes service communication requests made to the plurality of virtual hosts. Quality of service parameters associated with the virtual hosts are stored. Communication requests made to a specific one of the virtual hosts are detected. The quality of service parameters associated with the specific virtual host are obtained. Operating system resources are utilized to guarantee, to a child process of the server application program, a quality of service according to the obtained quality of service parameters associated with the virtual host. Communication between the virtual host and the client is allowed to proceed, the communication being managed by the child process.

摘要： Multiple virtual processes are each associated with a unique virtual process identifier. For each virtual process, a separate initialization process is started, from which all other processes included in the virtual process originate. The initialization process is associated with the appropriate virtual process identifier. System calls that create new processes are intercepted, and created processes are associated with the virtual process identifier of the appropriate initialization process. Multiple virtual processes are provided on a single, physical computer system.

摘要： File access rates of processes are regulated according to file type. An association table stores entries associating processes to be regulated with specific access rates for various file types. System calls that access files are intercepted, and a system call wrapper executes. The system call wrapper determines the type of file that is being accessed by the process. The system call wrapper examines the association table in order to determine if the calling process is associated with an access rate for the file type being accessed. If so, the system call wrapper regulates access to the file according to the appropriate rate.

摘要： The methods and systems of the invention enable connectionless-oriented server and client programs operating on processing systems to communicate with connection-oriented routines operating on different processing systems linked to connectionless or connection-oriented networks by establishing connections or communications virtual circuits between such programs. The connectionless-oriented server and client programs may be modified to communicate with a connection manager to establish a virtual circuit before initiating communications with the connection-oriented routines. The invention further utilizes encapsulators and decapsulators to enable communication programs to transfer data packets in a first format on an established virtual circuit over a network transmitting data in a second format.
