Computerized aspects monitor listening virtual local area network ports for multicast packets from hypervisor virtual machines that meet a multicast group definition, and retrieve source addresses for original hypervisor sources of detected ones of the multicast packets, bind the retrieved addresses to the multicast packets to generate encapsulated packets, and forward the encapsulated packets as user datagram protocol unicast packets to a destination address of a virtual extensible helper daemon defined for a destination hypervisor of a second virtual local area network. The destination address meets the multicast group definition for the first virtual local area network, and the second virtual local area network is geographically remote from and different from the first virtual local area network, and thus the aspects send the first user datagram protocol unicast packet through an internet protocol router to the designated receiving port.

Multicast helper to link virtual extensible LANs

A mechanism is provided for reducing network load in a software defined network. The mechanism is executed by a virtual machine hypervisor. The mechanism receives a network broadcast request sent by a source virtual machine node; acquires a first destination address in the network broadcast request; and reads a predefined mapping rule of the first destination address and a second destination address. An address of a node in the software defined network is configured by using the predefined mapping rule. The mechanism derives the second destination address corresponding to the first destination address according to the mapping rule. The mechanism responds to the network broadcast request by using the derived second destination address.

Reducing broadcast flooding in a software defined network of a cloud

A method, executed by a computer, for deploying an enterprise application includes configuring a plurality of application nodes for a software defined network using static IP addresses, capturing a plurality of images corresponding to the plurality of application nodes, preparing an application pattern that incorporates the plurality of images, and saving the application pattern for subsequent deployment. In one embodiment, the application is deployed onto a computing environment using the application pattern. The software defined network may be accessible by one or more service IP address. In one embodiment, one or more of the application nodes functions as a cloud computing software platform, such as an infrastructure-as-a-service (IaaS) solution. The software defined network may be an isolated virtual network. A computer program product and computer system corresponding to the methods are also disclosed herein.

Deployment of enterprise applications

A method and apparatus of managing a network connection of a network node comprising a NIC of a first type and a NIC of a second type. The method comprises: creating an interface device in the network node and setting the interface device to exchange data with a bridge connected to the NIC of the first type in response to detection of a failure in the NIC of the first type; determining a secondary node; instructing the secondary node to create and set a corresponding interface device; constructing a data channel between the interface device and the corresponding interface device, such that the data channel is capable of conducting data transmission using a network formed by the NICs of the second type. The apparatus corresponds to the above method.

Managing network connection of a network node

A system for deploying a Service-Oriented Architecture (SOA) deployment environment model and a system for modifying a deployed SOA deployment environment model. In the deploying system, deployment of the SOA deployment environment model is realized by acquiring a task list including tasks for deploying elements of the model, associating the tasks in the task list with the elements, and executing the tasks to deploy the elements of the model. In the modifying system, modification of the SOA deployment environment model is realized by acquiring a task list including tasks for modifying elements of the model, associating the tasks in the task list with the elements, and executing the tasks to modify the elements. Thus, the deployment of the SOA deployment environment model and the modification of the deployed SOA deployment environment model may be realized in a simple and easy-to-implement manner.

There is disclosed a method and system of testing server side objects in a client-server environment. A proxy is created of a first object on a server side on a client side. The proxy invokes a method of the first object on the server side to conduct a test by a test case deployed on the client side. A proxy is created of a second object on the client side by the proxy of the first object by the process of invoking the method of the first object on the server side. The creation of the proxies and objects are performed recursively.
