A computer system establishes offloaded connections over a network between requestor applications running on client nodes and server applications running on a server node. The connections are established through an aggregated plurality of network resources of the server node. Each of the aggregated plurality of server resources is operable to provide offloaded connections over the network and each is assigned to a unique private IP address. Connect queries are generated on behalf of requesting applications. Each of the connect queries specifies one of the server applications using a first endpoint tuple. The first endpoint tuple includes one of one or more IP addresses identifying the server node publicly on the network and a first port number uniquely identifying the server application. A valid set of bypass endpoint tuples are obtained that are translated from the first endpoint tuple specified in the query. Each tuple of the set includes a different one of the assigned private IP addresses. A connect request is issued over the network that specifies a selected one of the valid set of bypass endpoint tuples as the destination transport address for the connection.

Managing connections through an aggregation of network resources providing offloaded connections between applications over a network

Provided are an apparatus and method for managing related drivers associated with a bus driver. In one embodiment, the apparatus may comprise a physical device object table configured to contain a plurality of entries, a child device associated with each of the plurality of entries, each of the child devices configured to have a name associated therewith, the name configured to provide information about the child device sufficient to allow user environment applications an doperating system drivers to directly access the child device, and a virtual bus driver configured to interface between the child devices and an adapter.

Method and apparatus for managing related drivers associated with a virtual bus driver

Systems, methodologies, media, and other embodiments associated with key-configured topology connection management are described. One exemplary system embodiment includes a logic for mapping a resource to a port through which it can be accessed and a logic for determining whether a requestor will be granted a connection to the machine on which the resource resides based, at least in part, on membership in a key-configured topology. Membership in the key-configured topology may be determined by a connection management logic analyzing a key provided by the requestor in a request related to accessing the resource. The key may be internally generated by a key maintenance logic.

Key-configured topology with connection management

The disclosed embodiments relate to a communication device for use in a node of a system having a plurality of nodes. Each of the plurality of nodes may include network interface controllers ('NICs') and each of the NICs may have a public identifier and a private identifier associated therewith. A first protocol stack may operate according to a first protocol that is associated with the public identifier and a second protocol stack may operate according to a second protocol that is associated with the private identifier. A storage device may associate the public identifier of one or more of the NICs with the first protocol stack and the private identifier of one or more of the NICs with the second protocol stack. Received messages that incorporate the public identifier may be directed to the first protocol stack and messages that incorporate the private identifier may be directed to the second protocol stack.

Method and apparatus for performing connection management with multiple stacks

Systems, methodologies, media, and other embodiments associated with pre-configured topology connection management are described. One exemplary system embodiment includes an interface logic configured to acquire information about a set of client nodes, to pre-configure a subset of the client nodes into a pre-configured topology, and to make available information about the pre-configured topology. The exemplary system may also include a logic for mapping a resource to a port through which it can be accessed and a logic for determining whether a requestor will be granted a connection to the machine on which the resource resides based, at least in part, on membership in the pre-configured topology. Membership in the pre-configured topology may be determined by a connection management logic analyzing a node identifier provided by the requestor in a request related to accessing the resource.

Pre-configured topology with connection management

A computer system aggregates a plurality of network resources of a computer system. The plurality of network resources forms a bypass stack operable to provide offloaded connections to one or more applications available on the computer system. Each of the applications is associated with a first port number. The computer system itself is addressable on the network by a public IP address. The system assigns private IP addresses to uniquely identify each of the plurality of network resources. The system creates a socket for each application by which the application can communicate with the network. The socket is associated with a first endpoint tuple that includes the public IP address and the first port number associated with the application for which the socket is created. The socket is further associated with a set of bypass endpoint tuples that are translated from the first endpoint tuple, each of the set including a different one of the private IP addresses. Each of the bypass endpoint tuples is available to be a transport address to define an offloaded connection to the application through one of the network resources. The created socket can be a listening one at a server node or a connection one at a client node.
