According to one or more embodiments, a computer implemented method includes receiving, by an operating system of a computer server, a request to execute an instance of a computer application. The method further includes deploying a virtual container for the instance of the computer application, the virtual container is allocated a dynamic virtual interne protocol address (DVIPA). The method further includes instantiating an application instance of the computer application in the virtual container. The method further includes, based on a determination that the computer application is a non-native application for the operating system, creating for the virtual container, a virtual network interface card (NIC) that translates network communication between the application instance and a physical NIC of the computer server. The method further includes selecting, by the virtual NIC, a communication protocol stack, from multiple communication protocol stacks, to bind the application instance for transferring the network communication.

Associating virtual IP address of virtual server with appropriate operating system in server cluster

A method, system and computer-usable medium are disclosed for performing a network traffic combination operation. With the network traffic combination operation, a plurality of input queues are defined by an operating system for an adapter based upon workload type (e.g., as determined by a transport layer). Additionally, the operating system defines each input queue to match a virtual memory architecture of the transport layer (e.g., one input queue is defined as 31 bit and other input queue is defined as 64 bit). When data is received off the wire as inbound data from a physical NIC, the network adapter associates the inbound data with the appropriate memory type. Thus, data copies are eliminated and memory consumption and associated storage management operations are reduced for the smaller bit architecture communications while allowing the operating system to continue executing in a larger bit architecture configuration.

Efficient means of combining network traffic for 64Bit and 31 bit workloads

Efficient means of combining network traffic for 64Bit and 31Bit workloads

A method, computer program product, and device are provided for transparent separation of traffic. A communication interface is configured to transmit and receive traffic over a network. A stack is configured to dynamically identify the traffic as interactive traffic and non-interactive traffic. When the stack identifies the non-interactive traffic, the stack is configured to move the non-interactive traffic to a non-interactive queue.

Transparent quality of service

An improved technique is disclosed for routing data across multiple topology subnets, and for improving the connectivity between nodes in multiple topology subnets, by using a common connection network. A new type of virtual node, referred to herein as a 'global' virtual routing node or 'GVRN', is defined to represent connectivity to an underlying network that may extend beyond the boundaries of the topology subnets in the end-to-end path. This underlying network is also referred to as a &#x201c;common connection network&#x201d; or a &#x201c;global connection network&#x201d;. The present invention also defines novel techniques with which border nodes pass routing information between networks to convey connectivity to the GVRN. In many cases, use of GVRNs will result in shorter end-to-end data transmission paths.

Efficient connectivity between multiple topology subnets via common connection network

Methods, systems (apparatus) and computer program products are provided that control the data rate through a communications adapter having at least one guaranteed bandwidth connection through the communications adapter. The control of the data rate may be accomplished by assigning to guaranteed bandwidth connections, a maximum threshold value proportional to the amount of data to be transmitted through the communications adapter in a time interval to satisfy the guaranteed bandwidth of the connection. Guaranteed bandwidth connections are then limited to this amount of data in a time interval. Furthermore, an outbound data threshold for data sent tot he adapter and a total data threshold for data to or from the adapter may be established and best efforts data not sent to the adapter if either of these thresholds are exceeded within the time interval.

Methods, systems and computer program products for controlling data flow

Methods, systems (apparatus) and computer program products that control the data rate through a communications adapter having at least one guaranteed bandwidth connection through the communications adapter are provided. The data rate is controlled by assigning to the guaranteed bandwidth connection, a maximum threshold value proportional to the amount of data to be transmitted through the communications adapter in a time interval to satisfy the guaranteed bandwidth of the connection. The amount of data transmitted through the communications adapter for the guaranteed bandwidth connection is then counted so as to provide a connection data count associated with the guaranteed bandwidth. Data transmitted for the communications adapter associated with the guaranteed bandwidth connection is not transmitted to the communications adapter if transmission of the data would cause the connection data count to exceed the maximum threshold value assigned to the guaranteed bandwidth connection. The connection data count is then reset after expiration of the time interval.
