摘要： A network device can implement configurable socket aggregation to enable segmentation offload in the network device. In one embodiment, it is determined, at the network device, to create a network socket for an application of the network device to initiate a network connection for the application. Socket aggregation parameters are determined for the network socket associated with the application. The network socket is defined based, at least in part, on the socket aggregation parameters. A plurality of packets received from the application associated with the network socket are aggregated. It is determined, based on said aggregating the plurality of packets, whether at least one aggregation limit associated with the socket aggregation parameters is reached. An aggregate packet is provided to a network adapter of the network device to perform segmentation offload in response to said determining that at least one aggregation limit associated with the socket aggregation parameters is reached.

摘要： A service module that provides for discovery of one or more network interfaces connecting a prospective remote procedure call (RPC) client, facilitates the provision of RPC programs in a network including multi-horned systems. When a request for a network address to an RPC application providing an RPC program is received from the RPC client, the RPC bind daemon discovers from the module, using the client response address, over which interface(s) the client is accessible. The daemon then selects an address of a network path to the RPC application that the prospective client can access and returns the corresponding network address. The service module monitors the network stack for RPC get address requests and builds tables of client address entries with corresponding network interface identifiers. The entries are retired according to an aging policy.

摘要： A method includes receiving a command to migrate a workload partition from a source machine to a target machine. The source machine and the target machine are communicatively coupled to a first subnetwork and a second subnetwork, respectively. The workload partition has a source network address defined by network addressing of the first subnetwork. The method also includes determining a socket connection providing network communication between the workload partition and a host. The method includes notifying the host that the workload partition is migrating from the source machine to the target machine, wherein in response to the notifying the host is on alert to receive, through a network tunnel communication, an identification of a target network address that is assigned to the workload partition after the workload partition is migrated to the target machine. The workload partition is migrated from the source machine to the target machine.

摘要： User space applications can utilize custom network protocol timers. A registration request is received from an application to register a custom timer. Responsive to receiving the registration request, a handle is created. The handle is a pointer to be used by the application to reference the custom timer. The handle is forwarded to the application. When a custom timer is required, a request to use a custom timer is received from an application. The kernel is then requested to start the custom timer. A determination is then made as to whether a receipt confirmation is received from the kernel before expiration of the custom timer.

摘要： A system identifies a network socket on a machine by assigning a non-IP address socket anchor and a port number to the network socket. A socket anchor may comprise a globally unique number. In some embodiments, a socket anchor comprises a number having a preselected number of bits. The number having the preselected number of bits may comprise a selected number associated with the machine concatenated with a number of randomly generated bits. The number of bits of the selected number plus the number of randomly generated bits is equal to the preselected number of bits. In some embodiments, the selected number associated with the machine is a Media Access Control (MAC) address of a network interface associated with the machine.
