Abstract: Techniques are described for providing managed computer networks, such as for managed virtual computer networks overlaid on one or more other underlying computer networks. In some situations, the techniques include facilitating replication of a primary computing node that is actively participating in a managed computer network, such as by maintaining one or more other computing nodes in the managed computer network as replicas, and using such replica computing nodes in various manners. For example, a particular managed virtual computer network may span multiple broadcast domains of an underlying computer network, and a particular primary computing node and a corresponding remote replica computing node of the managed virtual computer network may be implemented in distinct broadcast domains of the underlying computer network, with the replica computing node being used to transparently replace the primary computing node in the virtual computer network if the primary computing node becomes unavailable.

Abstract: Generation of customized response messages is described. According to the method, an incoming communication request is received and a relationship between an initiator of the communication request and a recipient of the communication request is determined. Based on a number of calendars for the recipient, an availability of the recipient is determined. When the recipient is unavailable, a customized response message is generated. The customized response message 1) is based on the relationship between the initiator and the recipient and 2) indicates an estimated response time for the recipient based on the availability of the recipient.

Abstract: A network switch includes switch circuitry and multiple ports. The ports are configured to communicate with a communication network. The switch circuitry is configured to receive via the ports multiple packets, which are destined to a destination network node and which specify attributes used by the destination network node as cache keys for on-demand fetching of context items into a cache memory of the destination network node, to control a rate of fetching the context items into the cache memory at the destination network node, by ordering the received packets in a sequence, based on the attributes of the respective packets, using an ordering criterion that aims to place packets that access a common context item in proximity to one another in the sequence, and to forward the received packets to the destination network node, via the ports, in accordance with the ordered sequence.

Abstract: Some embodiments of the invention provide a novel architecture for capturing contextual attributes on host computers that execute one or more machines and for consuming the captured contextual attributes to perform services on the host computers. The machines are virtual machines (VMs) in some embodiments, containers in other embodiments, or a mix of both VMs and containers in still other embodiments. Some embodiments execute a guest-introspection (GI) agent on each machine from which contextual attributes need to be captured. In addition to executing one or more machines on each host computer, these embodiments also execute a context engine and one or more attribute-based service engines on each host computer. One of these service engines is a load balancer. Through the GI agents of the machines on a host, the context engine of that host in some embodiments collects contextual attributes associated with network events and/or process events on the machines.

An on-demand service broker provisions IaaS resources at service instance creating time. The service broker provides a catalog listing one or more service plans, each service plan corresponds to a set of available resources. A user device selects a respective service plan that matches specific needs of an application that consumes the resources. The service broker generates a deployment manifest based on the selected service plan. The service broker then submits the deployment manifest to a deployment system. The deployment system provisions the resources to the service instance according to the manifest generated by the service broker.

The terminal can comprise: a management unit which manages first synchronization information for identifying the at least one type of file among multiple files stored in the terminal; a transmitting and receiving unit which receives second synchronization information for identifying the at least one type of file stored in the server when the transmitting and receiving unit is connected through the server and the network; and a determination unit which determines whether synchronization is required between the terminal and the server by comparing the first synchronization information and the second synchronization information.

Abstract: A distributed data store may provide continuous backup for data stored in the distributed data store. Updates to data may be replicated amongst storage nodes according to a peer-to-peer replication scheme. A backup node may participate in the peer-to-peer replication scheme to identify additional updates to be applied to a backup version of the data in a separate data store. The backup node may obtain the updates according to the peer-to-peer replication scheme and update the backup version of the data. In some embodiments, configuration changes to the data in the distributed data store may be detected via the peer-to-peer replication scheme such that a backup node can adapt performance of backup operations in conformity with the configuration change.

Abstract: The transmission of data on computer networks according to one or more policies is disclosed.

Multiple network interfaces may be installed on a server to enable transmission of data from the single server according a number of discrete configuration settings implicated by the various policies. The multiple network interfaces may correspond to separate physical components, with each component configured independently to implement a feature of a policy. The multiple network interfaces may also correspond to a single physical component that exposes multiple network interfaces, both to the network and to the server on which it is installed.

Abstract: Data surveillance techniques are presented for the detection of security issues, especially of the kind where privileged data may be stolen by steganographic, data manipulation or any form of exfiltration attempts. Such attempts may be made by rogue users or admins from the inside of a network, or from outside hackers who are able to intrude into the network and impersonate themselves as legitimate users. The system and methods use a triangulation process whereby analytical results pertaining to data protocol, user-behavior and packet content are combined to establish a baseline for the data. Subsequent incoming data is then scored and compared against the baseline to detect any security anomalies. A centroid representing the normal population of the data packets is identified. The design allows establishing the context of various events of interest in the organization, thus enabling dynamic management of security policies.

Abstract: Technologies are described to increase a data limit for a user by introducing additional archive mailboxes as the original archive fills up or subsequently added archive mailboxes fill up. Thus, a user's data limit may be effectively removed through the use of additional archive mailboxes. In some examples, the additional mailboxes may be integrated into the architecture of the communication application such that their use is transparent to the user and/or an administrator of the communication application or associated service through the use of an application programming interface (API) that exposes a single multivalued strongly typed collection instead of dealing with multiple attributes and extending the schema every time a new type needs to be added. A mailbox locations attribute may act as the main storage of serialized mailbox locations and a mailbox identifier attribute may be used for indexing.

Upon detecting an operation initiated by the end user from a target terminal, the computer server determines primary target information to be pushed to the target terminal in accordance with the operation information and information of the end user. The computer server then acquires push control information for the primary target information, the push control information including push parameter information, related secondary target information and combined push frequency control information. Next, the computer server acquires push records of the primary and related secondary target information, respectively, according to the push parameter information.
