摘要： The invention discloses a method for calling video communication service by video communication terminal. The method comprises the steps of: (a) a first video communication terminal launches a call to a multipoint control unit (MCU) and sends an conference information needed for convening a conference to the MCU through an In-Band channel established between both sides; (b) the MCU convenes the conference according to the conference information received. The invention also discloses a message data form for transferring information through an In-Band channel in a video communication service. The message data form comprises: a data starting mark field, a data type field, a data length field, a field for no less than one piece of sub-information, a data ending mark field and a cyclic redundancy check field.

摘要： A tangible medium embodying instructions usable by a computer system to protect a plurality of guest virtual machines (VMs), which execute via virtualization software on a common host platform, from malicious code is described. A scan engine is configured to scan data for malicious code and determine a result of the scanning, wherein the result indicates whether malicious code is present in the data. A driver portion is configured for installation in an operating system of a target VM, which is one of the guest VMs. The driver portion intercepts an access request to a file, that originates within the target VM. The driver portion communicates information identifying a location of the data to be scanned by the scan engine without sending a copy of the data to the scan engine. The scan engine executes within the virtualization layer outside a context of the target VM.
