OREANDA-NEWS. June 09, 2011. NEC Corporation (NEC; TSE: 6701) announced today that domestic sales activities for its "Virtual PC Center 4.0" (VPCC 4.0), an enhanced version of the company's existing Virtual Desktop thin-client system, will begin on June 30, 2011.

The VPCC 4.0 enables a wide variety of terminals to access its Virtual Desktop through web browsers (*1) without installing special connection modules. It also features optimized architecture and operations, including a "Session Management Function" (Connection Broker) that strengthens transmissions between virtual desktops and terminals, as well as improved user-friendliness.

Furthermore, the VPCC 4.0 features a newly developed linking function through the XenDesktop(R) from Citrix(R), and enables virtual desktops to be accessed using either the RDP (*2) or ICA (*3) connection protocol. As a result, users may conveniently select the protocol that is most suitable to their working environment.

 Key features of the Virtual PC Center 4.0 include the following:
1) Access expanded to a wider variety of terminals

 A strengthened "Session Management Function" enables users to access a virtual desktop through a web browser, even when using terminals that aren't internally equipped with specialized connection modules. Therefore, the VPCC 4.0 system widely expands the selection of terminals that can access a virtual desktop, including NEC's Android(TM) based Cloud Communicators, and supports a wide variety of market needs, including the demands of telecommuting.
2) Strengthened transmissions between virtual desktops and terminals

 Supports both the RDP and ICA connection protocols for accessing virtual desktops. As a result, users can easily switch between an RDP connection when using the high-speed network of an office or an ICA connection when visiting off-site facilities. Existing users of VPCC may also utilize this function (*4).
3) Functions for efficient use of storage disk capacity

 Strengthening of the "Differential.Clone Function" (*5) which shares the overlapping portions of the OS used on virtual desktops and application disk images and efficiently deletes data by automatically determining the priority for differential data to be deleted based on the volume of differential data and production period. This improves overall system performance by making efficient use of storage disk capacity and reducing data volume.
4) Functions that facilitate system construction

 Implementation of functions that control virtual networks defined on virtualization platforms, which eliminates the need for recognizing the relationships between each virtual desktop and a virtual network during the time of system construction and relieves the burden of system architects.

 In recent years, greater attention has been drawn to the need for business continuity and disaster prevention measures which capitalize on thin client systems that provide access to desktop environments regardless of the location. These latest developments respond to this need by enabling users to continue working from remote locations, including their homes and distant offices, when they are unable to reach their usual workplace.

Looking forward, NEC aims to continue leveraging its VPCC thin client systems, both domestically and abroad, as part of strengthening "Client Integration Solutions," business continuity plans, security measures and reducing TCO.
*1)  Supports Internet Explorer7 and Internet Explorer8
*2) Remote Desktop Protocol (RDP)  Image transmission protocol from Microsoft
*3) Independent Computing Architecture (ICA)  Image transmission protocol from Citrix
*4)  Scheduled to be available in August 2011
*5) Differential.Clone Function:  The Differential.Clone function deletes the necessary disk capacity for virtual PCs that are managed by the "Master Image" and "Differential Data" by only maintaining the capacity for differential data of individual virtual PCs in a storage environment.
