An apparatus or corresponding method of managing Plain Old Telephone Service (POTS) lines in a Passive Optical Network (PON) to prevent an alarm system from generating an alarm during a software upgrade or maintenance of an Optical Network Terminal (ONT), Optical Line Terminal (OLT), or PON while maintaining the effectiveness of the alarm system. The ONT may store data related to a POTS line in nonvolatile memory. The ONT may activate the POTS line based on the data from the nonvolatile memory in an event of interruption in communications with an OLT prior to reestablishing communications with the OLT. The interruption in communications may be caused by an ONT reboot to complete an installation of a software upgrade. The ONT may energize the POTS line with a voltage in response to activating the POTS line to prevent the alarm system from generating the alarm.

In view of the foregoing, the present invention provides a unified software framework or architecture for distributed coordination of wireless devices and radios, referred to as Layer 2.5 Software MAC (or ‘SoftMAC’), which resides between the standard 802.11 MAC layer (Layer 2) and IP layer (Layer 3) to regulate and control the amount of traffic (both real-time and “best effort”) delivered to 802.11 MAC DCF interfaces. The software based design can be ported to different OS platforms and systems and is capable of handling new hardware interfaces and MAC mechanisms (e.g., 802.11e) with only a software upgrade. The invention thus provides a natural way to make end systems support coordination of different radios of device(s), achieving better performance. Advantages of the 2.5 layer software MAC in accordance with the invention include: (a) there are no hardware constraints; (b) heterogeneous wireless/radio support is provided at the 2.5 layer; and (c) an evolutionary and extensible solution with the ability to support future wireless MAC/PHY chip combinations.

A system and method for providing autonomous and remote vehicle maintenance and repair. The system employs an on-board diagnosis and prognosis module that monitors one or more vehicle buses to identify trouble codes and other information indicating a vehicle problem. The on-board module causes a telematic device on the vehicle to broadcast a message including a problem code that identifies the problem the vehicle is having. A remote repair center may receive the message and may identify a software upgrade patch associated with the problem that can be transmitted to the vehicle to upgrade its software to correct the problem. Also, the message may be received by another vehicle that is part of a broadcast network that has previously received the software upgrade patch to fix a problem on that vehicle, where the receiving vehicle may transmit the software upgrade patch to the vehicle having the problem.

A system and a method for installing software upgrades in a distributed computer system with no downtime. In a distributed computer system with cluster architecture, a number of service requests are redirected from a first instance of the cluster to a second instance of the cluster for execution. An execution in progress of a service request is also redirected from the first instance of the cluster to the second instance of the cluster. The execution in progress proceeds from a state that is saved on a public store by the first instance of the cluster. A software patch is applied to one or more software components running on an application server node of the first instance of the cluster. A number of service requests are redirected from the second instance of the cluster to the first instance of the cluster for execution. An execution in progress of a service request is also redirected from the second instance of the cluster to the upgraded first instance of the cluster. The execution in progress proceeds from a state that is saved on the public store by the second instance of the cluster. The software patch is applies on the one or more software components running on an application server node of the second instance of the cluster. A number of new service requests are directed to the upgraded second instance of the cluster for processing.

A method of operation includes the steps determining whether a version of operating software stored in the at least one mobile device is a current version of the operating software, and wirelessly updating the operating software stored in the at least one mobile device if it is determined that the operating software stored in the at least one mobile device is not the current version.

A method and system are provided for conducting a cluster software version upgrade in a fault tolerant and highly available manner. There are two phases to the upgrade. The first phase is an upgrade of the software binaries of each individual member of the cluster, while remaining cluster members remain online. Completion of the first phase is a pre-requisite to entry into the second phase. Upon completion of the first phase, a coordinated cluster transition is performed during which the cluster coordination component performs any required upgrade to its own protocols and data structures and drives all other software components through the component specific upgrade. After all software components complete their upgrades and any required data conversion, the cluster software upgrade is complete. A shared version control record is provided to manage transition of the cluster members through the cluster software component upgrade.

The automated software upgrade utility allows a customer, product supplier or software vendor to upgrade the operating system, firmware, applications and data files on any product regardless of the product type and characteristics. This upgrade process can be invoked from a remote location or via interaction directly with the target device.

When updating a running program in a system that uses a one-to-one backup program, fault-tolerance is lost while the backup program is itself being updated. To overcome this temporary loss of an available backup program, the number of backup copies of a software process is temporarily and dynamically increased during the software upgrade. The extra backup software processes may run on an unused processing unit or may run as an extra software process on a processing unit which is already performing a task. The technique may be applied to communication line cards.

Methods and systems are provided for conducting maintenance such as software upgrades in components and nodes within a computer network while maintaining the functionality of the computer network in accordance with prescribed performance parameters. A balance is achieved between the rate of performing a desired system upgrade and the necessary performance parameters by empirically determining anticipated system loads and selecting the maximum number of components that can be upgraded simultaneously while meeting the anticipated loads. Provisions are made for the staggering of components through the upgrade process and for the return of components to active service in the computer network in response to unanticipated load spikes. Validation of successful upgrades is also provided.

The invention provides a software update system and a method. The software update method provided by the invention comprises the following steps: an update strategy module sets an update strategy according to information of a query version management module; the update strategy module checks whether the current version of a client is in line with the update strategy or not after the client logs in a server and returns a check result to the client; the client starts an update execution module to initiate the software update when being in line with the update strategy; and the update execution module downloads an update software package from the server and executes the update. When a fault occurs, the update software package is replaced by a fault repair package, and the software update method can be utilized for realizing the fault repair. The software update process and the fault maintenance process can become simpler and more controllable by setting the update strategy through the software update system and/or the method, and the practical effects are very significant.

A software upgrade tool and procedure provide uninterrupted operation of a replication system during an upgrade of software components of the system. The replication system includes one or more user systems coupled to one or more target storage systems over a communications network, such as a computer network. Illustratively, each user system is embodied as a replication client, while each target storage system is embodied as a replication server. In addition, the replication system includes a management system embodied as a management server that manages configuration of the system, including during upgrade of the software components of the replication system. To that end, the software upgrade tool cooperates with the management server to query the configuration of “old” versions of the software components and to manage upgrades of those components to “new” versions of software. According to the invention, the upgrade tool and procedure enable both the old and new versions of the software components to run concurrently on the replication client and replication server, as well as the management server.
