A method and system provide information by which a host machine on which a virtual machine is running can be determined via a messaging channel between the virtual machines running on the host machine and the host machine. The virtual machine can then determine whether or not it should be executing. In order for the virtual machine to determine whether it can execute, it will need to know information about the host machine on which it will be running. Similarly, a virtual machine can determine whether it has been exposed to any viruses or whether a particular update has been run by knowing the host machines on which it has been run.

Method and system for determining a host machine by a virtual machine

A method and system provide tracking of a virtual machine by compiling information on the virtual machines in a network and sending the information to an administrative console. The administrative console can then determine the status of the virtual machines in the network. The administrative console can also establish a lineage of a virtual machine and the migration of a virtual machine from one host machine to another host machine. A virtual machine unique identifier assigned to each virtual machine by the system can be modified and used to track each virtual machine and associated host machine. A status can then be determined of the virtual machines, where the status can be a new virtual machine, a previously discovered virtual machine, a duplicated virtual machine, or a cloned virtual machine.

Tracking a virtual machine

A method and system provide security for a communication network and for one or more nodes within the network. Software can be distributed throughout the network from a centralized location or administrative console. The software can be made resident in the kernel of the operating system of a receiving node. The software can provide an observation functionality, an analysis functionality, a reporting functionality and a remediation functionality or some subset of those functionalities.

Method and system for cloaked observation and remediation of software attacks

Methods for managing a virtual machine wherein an administration console (AC) () transmits a query to a virtualization server (). The virtualization serverincludes at least one virtual machine (VM) (). AC () receives, in response to the query, identification of a VM () and establishes an authenticated communications link with a proxy machine () adapted for communicating with the VM (). AC () transmits over the authenticated communications link to proxy machine () the identification of the VM () and performs a management function with respect to the VM ().

Method for managing a virtual machine

To address the resources of the switch fabric, one embodiment of the invention provides a system and method for measuring the bandwidth of a switch fabric in addition to measuring the bandwidth in the line cards. The measured bandwidth is compared to the requirements of a routing request received in a controller. If the measured bandwidth of all resources, including the switch fabric, are sufficient to route data traffic in accordance with a predetermined SLA, then the controller reserves bandwidth in the switch fabric as well as in the line cards. Data can then be classified and queued in the line cards, and switched in the switch fabric, in accordance with the bandwidth reservations. Competing data traffic cannot rob the bandwidth in the switch fabric from the data having a bandwidth reservation. Thus, latency is controlled, and a predetermined QoS is met.

System and method for provisioning a quality of service within a switch fabric

An approach is provided for providing quality of service reservations in a packet-based radio communication network is disclosed. Connection information including connection rate is extracted from a dataflow from an application requesting connection-oriented service. A request message is sent to a proxy for establishing a connection based on the connection information over the network, wherein the proxy configures a classification rule based on flow criteria from the request message and accordingly initiates establishment of the connection over the network to a destination terminal. A confirmation that the connection can be established is selectively received according to the connection information, wherein the dataflow satisfying the flow criteria from the application is transported over the established connection to the destination terminal. This approach as particular applicability to shared capacity systems, such as a satellite communication system.

Proxy architecture for providing quality of service(QoS) reservations

The invention provides a proxy driver in the control plane of a router or switch providing a centralized Application Program Interface (API) between a switching application and multiple device drivers in the router chassis. Another embodiment of the invention provides a centralized method for enforcing a topology in the control plane of a router. Another embodiment of the invention provides a centralized method in the control plane for the discovery of resources, for example, as cards are added or removed from the router chassis.
