Techniques are provided for a high availability solution (e.g., a network attached storage (NAS) solution) with address preservation during switchover. A first virtual machine is deployed into a first domain and a second virtual machine is deployed into a second domain of a computing environment. The first and second virtual machines are configured as a node pair for providing clients with access to data stored within an aggregate comprising one or more storage structures within shared storage of the computing environment. A load balancer is utilized to manage logical interfaces used by clients to access the virtual machines. During switchover, the load balancer preserves an IP address used to mount and access a data share of the aggregate used by a client.

Approaches, techniques, and mechanisms are disclosed for efficiently buffering data units within a network device. A traffic manager or other network device component receives Transport Data Units (“TDUs”), which are sub-portions of Protocol Data Units (“PDUs”). Rather than buffer an entire TDU together, the component divides the TDU into multiple Storage Data Units (“SDUs”) that can fit in SDU buffer entries within physical memory banks. A TDU-to-SDU Mapping (“TSM”) memory stores TSM lists that indicate which SDU entries store SDUs for a given TDU. Physical memory banks in which the SDUs are stored may be grouped together into logical SDU banks that are accessed together as if a single bank. The TSM memory may include a number of distinct TSM banks, with each logical SDU bank having a corresponding TSM bank. Techniques for maintaining inter-packet and intra-packet linking data compatible with such buffers are also disclosed.

In accordance with an embodiment, described herein is a system and method for providing a partition file system in a multitenant application server environment. The system enables application server components to work with partition-specific files for a given partition, instead of or in addition to domain-wide counterpart files. The system also allows the location of some or all of a partition-specific storage to be specified by higher levels of the software stack. In accordance with an embodiment, also described herein is a system and method for resource overriding in a multitenant application server environment, which provides a means for administrators to customize, at a resource group level, resources that are defined in a resource group template referenced by a partition, and to override resource definitions for particular partitions.

A method, apparatus and system for transferring data from an apparatus called multi-protocol gateway in a network seamlessly that operates using a particular protocol, to another device that is either in the same network or outside operating in a totally different protocol is described. Today, to accomplish this requires external units, one per technology. For example, for supporting both WiFi and WiMAX devices today, we would require a WiFi access point, a WiMAX base station and a router. We provide plug-ins that would handle multiple protocols within the same gateway, to cater to devices that operate in those protocols. The apparatus translates between various protocols in the back end making it inexpensive and portable. The unit is scalable, grows with technology, and acts as a gateway to a local network. The device can be configured to address Quality of Service, Priority between technologies and fault- tolerance through management layer.

A Virtual Endpoint and a method therein for enabling end-to-end connectivity between a wireless communication network and a wired communication network are disclosed. A Virtual Endpoint is implemented in the wireless communication network and certain user and control plane features used in the wired communication network are implemented in the VEP. The VEP maps data traffic between a device in the wireless communication network and a device in the wired communication network based on Quality-of-Service (QoS) and performs required actions defined by the features used in the wired communication network.

A method, computer program product, and computer system for determining, by a computing device, a service instance count for each of a plurality of services to be executed on a plurality of host devices. A similarity between the plurality of services may be determined. A host instance count for the plurality of host devices may be determined based upon, at least in part, the similarity between the plurality of services. Each service instance may be allocated to a respective host device for execution based upon, at least in part, the similarity between the plurality of services, the service instance count, and the host service count.

This application discloses a resource indication method, and a related device and system. The method includes: generating resource indication information, where the resource indication information is used to indicate a reference signal resource allocated to a terminal device in a reference signal resource group in which the terminal device is located among a plurality of reference signal resource groups; and sending the resource indication information. According to the foregoing solution, flexibility of configuring the reference signal resource can be improved, so that better resource sharing is implemented and resource overheads are reduced.

Example methods and systems for intent-based network virtualization design are disclosed. One example may comprise: obtaining configuration information and traffic information associated with multiple virtualized computing instances, processing the configuration information and traffic information to identify network connectivity intents and mapping the network connectivity intents to a logical network topology template. Based on a first switching intent, a first group may be assigned to a first logical network domain and the logical network topology template configured to include a first logical switching element. Based on a second switching intent, a second group may be assigned to a second logical network domain and the logical network topology template configured to include a second logical switching element. Based on a routing intent, the logical network topology template may be configured to include a logical routing element.

Techniques are provided for load balancing for IP failover. A backend address of a first node is identified as a routing destination to which a request is to be routed by a load balancer based upon a load balancer rule mapping a frontend address, specified by the request as a request destination, to the backend address of the first node. The request is routed to a primary network interface of the first node using the backend address. The first node has a loopback interface with an address matching the frontend address for routing the request to a destination data structure based upon the request maintaining the frontend address as the request destination. Health probes are used by the load balancer for detecting a failure of the first node in order to failover to routing requests to a second backend address of a second node.
