A management capability is provided for a virtual computing platform. In one example, this platform allows interconnected physical resources such as processors, memory, network interfaces and storage interfaces to be abstracted and mapped to virtual resources (e.g., virtual mainframes, virtual partitions). Virtual resources contained in a virtual partition can be assembled into virtual servers that execute a guest operating system (e.g., Linux). In one example, the abstraction is unique in that any resource is available to any virtual server regardless of the physical boundaries that separate the resources. For example, any number of physical processors or any amount of physical memory can be used by a virtual server even if these resources span different nodes. A virtual computing platform is provided that allows for the creation, deletion, modification, control (e.g., start, stop, suspend, resume) and status (i.e., events) of the virtual servers which execute on the virtual computing platform and the management capability provides controls for these functions. In a particular example, such a platform allows the number and type of virtual resources consumed by a virtual server to be scaled up or down when the virtual server is running. For instance, an administrator may scale a virtual server manually or may define one or more policies that automatically scale a virtual server. Further, using the management API, a virtual server can monitor itself and can scale itself up or down depending on its need for processing, memory and I / O resources. For example, a virtual server may monitor its CPU utilization and invoke controls through the management API to allocate a new processor for itself when its utilization exceeds a specific threshold. Conversely, a virtual server may scale down its processor count when its utilization falls. Policies can be used to execute one or more management controls. More specifically, a management capability is provided that allows policies to be defined using management object's properties, events and / or method results. A management policy may also incorporate external data (e.g., an external event) in its definition. A policy may be triggered, causing the management server or other computing entity to execute an action. An action may utilize one or more management controls. In addition, an action may access external capabilities such as sending notification e-mail or sending a text message to a telephone paging system. Further, management capability controls may be executed using a discrete transaction referred to as a “job.” A series of management controls may be assembled into a job using one or management interfaces. Errors that occur when a job is executed may cause the job to be rolled back, allowing affected virtual servers to return to their original state.

The present disclosure controls the network and manages resources for managing network assets through in a network-based supply chain framework. Network assets are available to network users. One user may submit information reguarding potential for growth, the capacity, or the technological level of one of the network assets. Another user may submit similar information about another network asset. Based on the information from the users, the system may determine the optimal set of network assets. When network events about the assets are recieved, the events can be filtered, correlated and isolated. These events can then be translated into a standard object form for facilitating the determination of the problem causing the network event.

Performing data management operations on replicated data in a computer network. Log entries are generated for data management operations of an application executing on a source system. Consistency point entries are used to indicate a time of a known good, or recoverable, state of the application. A destination system is configured to process a copy of the log and consistency point entries to replicate data in a replication volume, the replicated data being a copy of the application data on the source system. When the replicated data represents a known good state of the application, as determined by the consistency point entries, the destination system(s) may perform a storage operation (e.g., snapshot, backup) to copy the replicated data and to logically associate the copied data with a time information (e.g., time stamp) indicative of the source system time when the application was in the known good state.

Described herein is a system for executing distributed transactions. A coordinator and one or more participants cooperate to execute a distributed transaction, the distributed transaction including for each participant a transaction executed by the participant. To manage the transaction, the coordinator and the participant communicate over a network using, for example, a stateless protocol. Before each participant commits the transaction, the participants determine that the coordinator has committed the transaction. The coordinator commits the transaction after receiving acknowledgment from all the participants that they will commit the transaction. To determine whether the coordinator has committed the transaction, a participant transmits a message to the coordinator to acknowledge that it will commit the distributed transaction. The participant commits its respective transaction if it receives an acknowledgement from the coordinator. For the particular transaction being executed by a participant, the participant prevents other transactions from modifying a data item affected by the particular transaction. The participant will prevent such modifications until termination criteria for the particular transaction is satisfied, in which case the participant terminates the transaction.

A method and system for detecting anomalous action within a computer network is provided herein. The method starts with collecting raw data from at least one probe sensor that is associated with at least one router, switch or at least one server which are part of the computer network. Next, the raw data is being parsed and analyzed and meta-data is created from the raw data. Computer network actions are being identified based on existing knowledge about network protocols. The meta-data is associated with entities by analyzing the identified network actions and correlating between different computer network actions. Finally, creating at least one statistical model of the respective computer network said model including network actions' behavior pattern and online or batch detection of anomalous network actions associated with entities based on the statistical models.

A client-server architecture includes a plurality of clients and a plurality of servers. Information resources are replicated among the servers. According to one aspect, the invention includes an intermediary device called a "depot" sitting transparently between a client and a pool of servers which have the replicated information resources. The depot dynamically distributes multiple sessions contained in a client request among the servers. This architecture realizes a good granular scaleability of servers, and improved server throughput with a good response time. Multiple depots also realize robustness.

A network caching system for streamed applications provides for the caching of streamed applications within a computer network that are accessible by client systems within the network. Clients request streamed application file pages from other client systems, proxy servers, and application servers as each streamed application file is stored in a cache and used. Streamed application file page requests are broadcast to other clients using a multicast packet. Proxy servers are provided in the network that store a select set of streamed application file pages and respond to client requests by sending a response packet containing the requested streamed application file page if the streamed application file page is stored on the proxy server. Streamed application servers store all of the streamed application file pages. Clients try to send requests to streamed application servers as a last resort. Clients can concurrently send requests to other clients, to a proxy server, and to a streamed application server. Clients measure the response time to the clients requests placing a positive weighting on the more responsive request path and sending subsequent requests to the more positively weighted request path first.

Use of a centralized control architecture in a network. Policy declaration, routing computation, and permission checks are managed by a logically centralized controller. By default, hosts on the network can only route to the network controller. Hosts and users must first authenticate themselves with the controller before they can request access to the network resources. The controller uses the first packet of each flow for connection setup. When a packet arrives at the controller, the controller decides whether the flow represented by that packet should be allowed. The switches use a simple flow table to forward packets under the direction of the controller. When a packet arrives that is not in the flow table, it is forwarded to the controller, along with information about which port the packet arrived on. When a packet arrives that is in the flow table, it is forwarded according to the controller's directive.

A suspicious activity capture system can comprise a tap configured to copy network data from a communication network, and a controller coupled to the tap. The controller is coupled to the tap and is configured to receive the copy of the network data from the tap, analyze the copy of the network data with a heuristic to flag the network data as suspicious, and simulate transmission of the network data to a destination device.

A method and system for selecting a network to establish a connection to from a set of available network includes a network database providing historical information about each of the networks and sends the database information to end user terminals. The end user terminals monitor real-time performance information about each of the available networks and can send this information to the network database. The end user terminals also include network connection policy information which can be used to make the selection decision. The end user terminal determines a network quality score for each available network as a function of the historical information from the network database, the real-time performance information about each available network and the network connection policy information. The end user terminal can select the available network as a function of the network quality score, for example, selecting the available network with the highest network quality score.
