Abstract: A migration system provides data deduplication for migrating virtual machines across a network. The system maintains a centralized deduplication dictionary storing key-value pairs of identifiers and corresponding virtual machine data mapped to the identifiers, which are transferred as part of a migrating virtual machine. The migration system can store at least a portion of the virtual machine data, in intermediate storage implemented on one or more storage devices. The intermediate storage is queryable using a hash-generated key of the stored data. After an initial transfer of data from a source computing environment to a target computing environment, a requesting computing environment can subsequently initiate a data transfer by first querying the migration system to determine if the target data has already been transferred and stored in intermediate storage.

Abstract: Disclosure is made of methods, apparatus and system for migrating virtual machines (VMs) between source and destination in a computing environment and, more specifically, to replication based migration. VMs migration is controlled so as to manage transferal of data associated with one or more VMs from a source location to a destination location to meet certain user definable or system constraints. Dynamic control and adjustment of system parameters associated with the migration is also disclosed.

Abstract: Aspects of the disclosure are directed to modifying and preserving virtual machine settings at a target computing environment as virtual machine settings change for a migrating virtual machine. The migration system balances matching the most up-to-date settings of the virtual machine in its source environment, with making changes as necessary to the settings of the virtual machine so that the settings are compatible with a target computing environment, updating the settings as needed. The migration system can continuously or periodically monitor changes in source virtual machine settings and/or in the source or target computing environments, and update target virtual machine settings up to the point at which a cut-over operation is performed and migration is complete.

Abstract: Aspects of the disclosure provide for ordering and scheduling operations for migrating virtual machines in parallel. A migration system can provide for ordering and scheduling operations to be performed when only a subset of virtual machines slated for migration can be migrated at a time. Aspects of the disclosure provide for migrating interdependent virtual machines. Interdependent virtual machines may at least partially rely on data generated by applications or services of other virtual machines in the group. A migration system schedules and orders migration cycles to reduce the down time of services implemented by the virtual machines during cut-over operations in the migrations of the virtual machines.

Abstract: A towel holding handle assembly includes a handle bar that can be mounted on a variety of supporting surfaces for use as an operating handle. The handle bar receives two elongate clamping elements within a hollow interior thereof which are accessible through an opening along one side of the handle bar. The clamping elements are biased from a released position in which the first and second clamping elements are spaced apart to receive a portion of a towel inserted therein and a clamped position in which the first and second clamping elements are closer to one to clamp the retain the inserted portion of the towel clamped therein.

Abstract: Performing operations on nodes of distributed computer networks. A request to upgrade a first acceleration node in a computer network is identified. A second acceleration node that is linked to the first acceleration node is identified. A bypass link to the second acceleration node from the first acceleration node is established. The bypass link is configured to transmit new connections received for handling by the first acceleration node to the second acceleration node for handling by the second acceleration node during upgrading of the first acceleration node. Upon establishing the bypass link, the first acceleration node is upgraded in response to identifying the request.

One computer-implemented method includes calculating a direct connection cost for network traffic between two points in a network, the network including one or more nodes of an accelerated application delivery (AccAD) network, calculating an AccAD connection cost for the network traffic between the two points in the network using at least one node of the AccAD network, comparing the calculated direct connection cost and the AccAD connection cost, and determining whether the direct connection cost is greater than the sum of the AccAD connection cost and a minimum cost threshold value.

Abstract: According to some embodiments, a method and apparatus are provided to receive, at a central security manager located on a computer network, first network information from a first network resource associated with a first network perspective and receive, at the central security manager, second network information from a second network resource associated with a first network perspective. The first network information and the second network information are aggregated. A potential attack to the network is determined and a defensive measure is implemented in response to the potential attack to the network.

Abstract: Pre-fetching resources by predicting user actions. Features of multiple users and of multiple client computer systems associated with the multiple users are obtained. From these features, multiple segments are generated, each including a proper subset of the multiple users. Users in the proper subset share a common feature. For a segment, resources that have at least a threshold level of likelihood of being requested by a user included in the segment are pre-fetched, i.e., obtained before the resources have been requested. A client computer system associated with the user in the included segment is identified, and the obtained resources are stored for providing to the user.

Abstract: This disclosure relates to synchronizing dictionaries of acceleration nodes in a computer network. For example, dictionaries of a plurality of acceleration nodes of a client-server network can be synchronized to each include one or more identical data items and data identifier pairs. Synchronization can include transmitting a particular data item, or a combination of a data item and an associated data identifier, to another acceleration node which includes it in its dictionary. A particular acceleration node can, instead of transmitting a data item, transmit an associated data identifier to another acceleration node. As all (or a subset) of the acceleration nodes can have an identical dictionary when employing the methods described herein, the particular acceleration node can use the same dictionary to communicate with all (or the subset of) other acceleration nodes of the computer network.
