摘要： A method, system, and program for redirecting client connection requests among sockets providing a same service are provided. An application requests multiple sockets from a kernel. In addition, the application generates a socket call option to bind the sockets to a particular port number and passes a list of the sockets to the kernel, where the list indicates that the sockets will all provide access to server systems providing the same service. In response, the kernel sets up the sockets, bound to the same port, and set to reference one another. Then, when a connection request is received for a first socket in the list with a queue that is full, the kernel redirects the connection request to a second socket in the list with available queue space. Thus, rather than drop the connection request from the first socket when it lacks available queue space, the connection request is redirected to another socket providing access to the same service.

摘要： A method, system, and program for accessing data processing systems behind a NAT enabled network are provided. According to one aspect of the present invention, a NAT data processing system is located behind a NAT enabled network with a NAT device as a gateway to the NAT enabled network. A client system located outside the NAT enabled network queries the NAT device for the address of the NAT data processing system located behind the NAT enabled network. The query is automatically routed through the NAT device to a DNS server. The DNS server then returns an address for the NAT data processing system and source routing for the NAT device. The NAT device forwards the address and source routing to the client system. Then, the client system sends packets to the NAT data processing system at the address with source routing through the NAT device, such that the NAT data processing system behind the NAT enabled network is directly accessed by the client system from outside the NAT enabled network.

摘要： A method, system, and program for monitoring thread usage to dynamically control a thread pool are provided. An application running on the server system invokes a listener thread on a listener socket for receiving client requests at the server system and passing the client requests to one of multiple threads waiting in a thread pool. Additionally, the application sends an ioctl call in blocking mode on the listener thread. A TCP layer within the server system detects the listener thread in blocking mode and monitors a thread count of at least one of a number of incoming requests waiting to be processed and a number of said plurality of threads remaining idle in the thread pool over a sample period. Once the TCP layer detects a thread usage event, the ioctl call is returned indicating the thread usage event with the thread count, such that a number of threads in the thread pool may be dynamically adjusted to handle the thread count.

摘要： A communication system which facilitates distribution of electronic communications for a user account includes an emergency auto-reply agent that scans each received communication addressed to the user account for a particular communication sent from at least one emergency address specified for the user account separate from the address of the user account. Responsive to the communication system detecting the particular communication sent from one of the emergency addresses, the emergency auto-reply agent parses the content of the particular communication to detect whether the particular communication comprises a required password. Responsive to detecting the required password within the content of the particular communication, the emergency auto-reply agent directs the communication system to compose and send auto-reply communications from the user account in reply to received communications addressed to the user account.
