Systems, methods and articles of manufacture are disclosed for identifying and resolving port conflicts during application deployment. The port conflicts may be identified based on application documentation and active port information. The port conflicts may be resolved by identifying an available port and providing information about the available port to a conflicting application. The port conflicts may also be resolved by identifying an available IP address and providing a port on the available IP address to a conflicting application. Further, if conflicting applications allow port sharing, the port conflicts may be resolved by providing port sharing information to the conflicting applications.

Automatic port conflict resolution during application deployment

Systems, methods and articles of manufacture are disclosed for configuring a network device on a private network. A network device broadcasts a status message to the private network. The network device receives a request from a client and sends a response. The network device and the client establish a direct message route wherein one or more network configuration settings are exchanged between the client computer and the network device.

Network device configuration

Systems, methods and articles of manufacture are disclosed for resolving hostnames on a private network with a public Internet server. One embodiment of the invention provides for a public Internet server configured to generate a private network ID when a new private network is identified, wherein the private network ID is a unique reference to all nodes within a private network and wherein the private network is comprised of one or more private DNS servers. The public internet server stores the private network ID and an IP address for at least one or more private DNS servers on the private network and sends, upon request, the private network ID to at least one of the private DNS servers.

Resolving hostnames on a private network with a public internet server

Systems, methods and articles of manufacture are disclosed for resolving hostnames on a private network with a distributed DNS server configuration. One embodiment of the invention provides for a client resolver configured to communicate with a distributed network of servers. The client resolver receives a hostname query and determines if the hostname query is of the type single label hostname or fully qualified hostname. If the hostname query received is of the type fully qualified hostname, the client resolver routes the hostname query to a server with a longest matching domain suffix. If the hostname query received is of the type single label hostname the client resolver generates one or more new fully qualified hostnames and routes the hostname query to each server on the private network.

TCP/IP host name resolution on a private network

Method, apparatus and article of manufacture for acquiring a buffer after data from a remote sender (e.g., client) has been received by a local machine (e.g., server). Because the client data has already been received when the buffer is acquired, the buffer may be sized exactly to the size of the client data. In general, the buffer may be caller supplied or system supplied.

Determining on demand right size buffering within a socket server implementation

Systems methods and computer products for reclaiming resident buffers on demand. Exemplary embodiments include systems and methods for reclaiming resident buffers, including allocating a buffer, determining that the buffer allocation pushes the buffer pool below a reclaim threshold, marking an oldest in-use buffer to be reclaimed, determining that all messages referencing the buffer have been queued, allocating a new buffer and performing a swap of the oldest in-use buffer and the new buffer, performing a free message block operation and updating a message block by updating a set of read and write pointers to point to the new buffer.

Reclaiming resident buffers when a reclaim threshold has been exceeded by swapping the oldest in use buffer and a new buffer, and referencing the new buffer via an updated set of read and write pointers

Method for determining on demand right size buffering within a socket server implementation

Method, apparatus and article of manufacture for continuous modes for both asynchronous accepts and asynchronous receives. A single asynchronous accept is performed on a listening socket and a single asynchronous receive is performed on each connected socket. The continuous mode inputs result in queuing data structures on a pending queue. The contents of the pending data structures on the pending queue are copied to completion queues, while the pending data structures remain on the pending queue.

Method for continuous I/O request processing in an asynchronous environment

Apparatus, methods and articles of manufacture for handling messages in a client-server environment. In general, computers of a client-server environment are configured with sockets to facilitate network communications. A socket of at least one of the computers is configured to recognize a format of a message to be received from another computer, whereby the socket is configured to handle receiving the message without invoking the application until the message is completely received. In general, the message may be formatted with a length field or terminating characters. In one embodiment, the socket utilizes a record definition to recognize the message format.
