High Availability Network Address Translation

A computing environment, such as a cloud computing environment, may include nodes performing NAT for a plurality of workloads. An active node performs NAT for the workloads, including maintaining a NAT table. The active node may create sub-interfaces for the workloads and function as a DHCP server. The NAT table and sub-interfaces may be recreated on a standby node. Upon detecting failure, a routing table is updated to direct workloads to connect to the standby node and traffic may continue to be processed by the standby node without disrupting network or application sessions.

Failover system and method replicating client message to backup server from primary server

A failover system, server, method, and computer readable medium are provided. The system includes a primary server for communicating with a client machine and a backup server. The primary server includes a primary session manager, a primary dispatcher a primary order processing engine and a primary verification engine. The method involves receiving an input message, obtaining deterministic information, processing the input message and replicating the input message along with the deterministic information.

Distributed failover for multi-tenant server farms based on load times of replicated tenants
09798634 · 2017-10-24 · ·

A failover manager may be configured to determine a plurality of tenants executable on a server of a plurality of servers, each tenant being a virtual machine executable on the server in communication with at least one corresponding user. The failover manager may include a replicated tenant placement selector configured to dispatch a first replicated tenant for a first tenant of the plurality of tenants to a first standby server of the plurality of servers, and configured to dispatch a second replicated tenant for a second tenant of the plurality of tenants to a second standby server of the plurality of servers. The failover manager also may include a replicated tenant loader configured to activate, based on a failure of the server, the first replicated tenant on the first standby server to replace the first tenant, and the second replicated tenant on the second standby server to replace the second tenant.

Access point controller failover system

An access point IHS group controller failover system includes a first access point IHS group controller that controls a first access point IHS group that includes plurality of access point IHSs. Following a failure of the first access point IHS group controller, the first access point IHS broadcasts a first access point IHS identifier to a first subset of the plurality of access point IHSs. The first access point IHS then registers the first subset of the plurality of access point IHSs as members of a second access point IHS group, and controls at least some functions of the second access point IHS group. When the first access point IHS detects activity from the first access point IHS group controller, it instructs the first subset of the plurality of access point IHSs in the second access point IHS group to reconnect to the first access point IHS group controller.

Communicating health status when a management console is unavailable for a server in a mirror storage environment

Provided are a computer program product, system, and method for communicating health status when a management console is unavailable for a server in a mirror storage environment. A determination at a first server is made that a management console is unavailable over the console network. The first server determines a health status at the first server and the first storage in response to determining that the management console cannot be reached over the console network. The health status indicates whether there are errors or no errors at the first server and the first storage. The first server transmits the determined health status to the second server over a mirroring network mirroring data between the first storage and a second storage managed by the second server. The determined health status is forwarded to an administrator.

Adaptive Session Reliability over Multiple Transports
20170339258 · 2017-11-23 ·

Methods, systems, and computer-readable media for providing reliable switching between different transport protocols (e.g., TCP and UDP) are presented herein. In some embodiments, a computing platform may stop transmission over a transport protocol. Subsequently, the computing platform may synchronize buffers between a client and a host. For example, the buffer may include acknowledgments for undelivered reliable packets between the client and the host. Next, the computing platform may resume transmission over a different transport protocol. In some embodiments, when establishing an initial connection between a client and a host, connections may be attempted in parallel over multiple transport protocols. After a connection over a first transport protocol is established, if a connection is later established over a second transport protocol, the connection may be transitioned to the second transport protocol. Also, ticketing semantics may be preserved in the switch between the different transport protocols.

SYSTEMS AND METHODS FOR CONNECTION CREATION
20170303070 · 2017-10-19 ·

A method for wireless communication by an advertising Bluetooth (BT) device is described. The method includes detecting an energy level that indicates a corrupt connection request sent by a remote BT device. The method also includes determining that there is a failed connection attempt based on the corrupt connection request. The method further includes performing connectable advertising at a faster rate to allow the remote BT device to reconnect quickly.

SYSTEM THAT SAVES DATA, SERVER, AND METHOD
20170302807 · 2017-10-19 ·

An object of the present invention is to provide a system capable of preventing data from being lost even in the case where upload of the data has failed and of preventing saved data from being deleted without a user knowing it. The present invention is a system that saves data in a storage server and the system includes: a determination unit configured to determine whether or not upload of the data to the storage server has succeeded; a saving unit configured to temporarily save the data in the case where the upload has failed; a notification unit configured to notify a user of that the temporarily saved data exists in the case where the saving unit temporarily saves the data; a retry unit configured to try reupload of the temporarily saved data to the storage server; and a deletion unit configured to delete the temporarily saved data in the case where the reupload has succeeded.

DUAL SERVER BASED STORAGE CONTROLLERS WITH DISTRIBUTED STORAGE OF EACH SERVER DATA IN DIFFERENT CLOUDS
20170302507 · 2017-10-19 ·

A storage controller comprising a first server and a second server is maintained. Data of the first server is stored in a first storage cloud, and data of the second server is stored in a second storage cloud. In response to a failure of the second server, the first server performs operations of the second server by using the stored data of the first server in the first storage cloud.

MOBILE MEDICINE COMMUNICATION PLATFORM AND METHODS AND USES THEREOF

Telemedicine systems and methods are described. In a telemedicine system operable to communicate with a remote operations center, communications can be transmitted/received using a transceiver having an antenna. The antenna can include first and second di-pole antenna elements, the first di-pole antenna element being vertically polarized and the second di-pole antenna element being horizontally polarized. A controller of the system can establish, using the transceiver, a telemedicine session with the operations center using a Transport Morphing Protocol (TMP), the TMP being an acknowledgement-based user datagram protocol. The controller can also mask one or more transient network degradations to increase resiliency of the telemedicine session. The telemedicine system can include a 2D and 3D carotid Doppler and transcranial Doppler and/or other diagnostic devices, and provides for real-time connectivity and communication between medical personnel in an emergency vehicle and a receiving hospital for immediate diagnosis and treatment to a patient in need.
