Abstract: A method, apparatus and computer program product for reducing the data transmitted over an external communication link using the TCP protocol from a first application resident in a first computer and to a second application resident in a second computer. The method, apparatus and computer program product include establishing a first virtual socket in the first computer in response to each connection request by the first application for receiving request data originated by the first application. A first real socket in the first computer and a second real socket in the second computer are established to connect the first computer to the second computer over the external communication link and are maintained until the request data has been provided to the second application. In the second computer a second virtual socket is established for each connection request by the first application wherein the second virtual socket corresponds to a first virtual socket established in the first computer in response to a connection request by the first application. Request data associated with a first virtual socket is multiplexed onto the first real socket and transmitted over the external communication link utilizing the TCP protocol. The multiplexed request data is received from the external communication link by the second real socket and demultiplexed. The demultiplexed request data is provided to the corresponding second virtual socket which provides the request data to the second application.

Abstract: A service, requested by a server system 205, 206, is defined as nodes in a service model 211 in a management engine system 201. Each node defines the type of resource required for that node as an abstract method. The management engine 209 find resource manager systems 202, 203, which implement the resource, by searching a service provider catalogue 210. The management engine requests the resource manager to provide its application programming interface (API). The management engine overrides the abstract interface in the node with the interface of the selected resource manager to provide the specific resource. The resources may be data storage, application programs, computing resources, networking components or middleware.

Abstract: A video distribution management system utilizes a shared video library and a wide area network to deliver video files to local caches on the local area networks serving a subset of local viewing stations. A combination of direct local cache access, scheduled future local cache access and speed match distribution of video files makes the overall system both efficient and economical. In particular, a locally stored preface of a video file can be immediately viewed on the local area network while the balance of the video file is transmitted from the remote video library.

Abstract: A single non-privileged instruction copies a page of data from a source virtual address to a destination virtual address, regardless of which of plural electronic storage media contain the page locations, and without the intervention of any supervisory program when media and virtual addressing have been previously determined for the locations of the subject pages. The instruction is not required to specify which of the plural media it will use, does not require its user to know what backing media it will access, does not require main storage (MS) to be one of its backing media, and allows different types of physical addressing to be used by the different backing media. The instruction can lock any page for use in an MP. No physical direction of data movement is provided within the non-privileged machine instruction, which only designates virtual direction of movement. The separation of virtual direction from physical direction is done by avoiding instruction control over selection of electronic media. The non-privileged instruction can nevertheless express a preference for obtaining a copy of the destination page in an electronic medium in which the content of the page can be processed by further instructions. Also, the instruction can cause invocation of a privileged control program to avoid the need for a following condition code test instruction. A privileged instruction is also provided to wait for the completion of the unprivileged instruction and to invalidate a non-MS medium page whether it is unlocked or locked, either correctly or incorrectly.
