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

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

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.
