摘要： Disclosed is a system, method, and program for caching files retrieved from a server over a network. A computer system receives a request from a requesting computer system for a file maintained on the server. The computer system is capable of communicating with the server via the network. The computer system retrieves the requested file from the server over the network and stores a copy of the requested file in a primary storage. The computer system further returns another copy of the requested file to the requesting computer system. The computer system determines retrieved files to migrate from the primary storage to a secondary storage and migrates the determined retrieved files from the primary storage to the secondary storage. To determine the files to migrate from primary storage to secondary storage, the computer system may determine a distribution of file requests per unit of time according to file size for files maintained in the primary storage and the secondary storage. The computer system then processes the determined distribution and a provided maximum number of file requests per unit of time to determine a minimum file size for migration. Files having a size greater than the minimum file size for migration are migrated from the primary storage device to the secondary storage device.

摘要： Disclose is a system, method, and program for accessing files maintained in a server that is capable of being accessed over a network. A request is received for a file maintained in the server. A determination is then made as to whether a copy of the requested file is stored in a storage system. The system then determines a delay time associated with retrieving the copy of the requested file from the storage system after determining that the storage system includes the copy of the requested file. A determination is then made as to whether the delay time exceeds a maximum delay time. The system retrieves the requested file from the storage system to return to the request after determining that the delay time does not exceed the maximum delay time. Alternatively, the system retrieves the requested file from the server over the network to return to the request after determining that the delay time exceeds the maximum delay time.

摘要： Messages containing non-dictionary and dictionary data objects are quickly exchanged between sending and receiving devices. Data stores of the devices contain a common dictionary cross-referencing each of multiple data objects with a different dictionary index code. Data objects in the dictionary are likely to be frequently exchanged. Prior to transmission of data objects, the sending device searches its dictionary for each data object. Each data object may include text, graphics, program segments, or another type of data object. If the data object appears in the dictionary, the sending device obtains its dictionary index code. Next, the sending device transmits a message representing the data objects to the receiving device. The message includes multiple subparts each corresponding to a different data object. If a data object is not present in the dictionary, its subpart comprises the content of the data object without any dictionary encoding. If a data object is represented in the dictionary, its subpart comprises the data object's index code from the dictionary. Flags included in the message distinguish between dictionary and non-dictionary subparts. The receiving device interprets received messages, reviewing flags in the message to determine which subparts comprise dictionary index codes. Each index code is cross-referenced in the receiving device's dictionary to obtain the unencoded data object, which is provided as an output. Each non-dictionary data object is provided as an output directly.
摘要翻译： 在发送和接收设备之间快速交换包含非字典和字典数据对象的消息。 设备的数据存储包含一个通用字典，其中使用不同的字典索引代码交叉引用多个数据对象中的每一个。 字典中的数据对象可能会频繁更换。 在发送数据对象之前，发送设备在每个数据对象的字典中搜索。 每个数据对象可以包括文本，图形，程序段或另一类型的数据对象。 如果数据对象出现在字典中，则发送设备将获取其字典索引码。 接下来，发送装置向接收装置发送表示数据对象的消息。 该消息包括各自对应于不同数据对象的子部分。 如果数据对象不存在于字典中，则其子部分包含数据对象的内容，而没有任何字典编码。 如果数据对象在字典中被表示，其子部分包括来自字典的数据对象的索引代码。 消息中包含的标志区分字典和非字典子部分。 接收设备解释接收到的消息，查看消息中的标志以确定哪些子部分包括字典索引代码。 每个索引代码在接收设备的字典中被交叉引用，以获得作为输出提供的未编码的数据对象。 每个非字典数据对象作为输出直接提供。

摘要： A server selectively filters and caches internet downloading requests from attached terminals, subsequently resubmitting cached requests appropriately. With the terminals connected to the internet via the server, the server is a focal point for all internet requests. Initially, the server receives a request from an attached terminal to download desired information from the internet. The received request contains a download code, such as a universal resource locator, identifying the desired information. The server determines whether the requested download should proceed based upon information obtained from one or more of sources such as (1) server-related limitations and status, (2) limitations set forth in a user profile, and (3) characteristics of the download itself, obtained from the download code and by tentatively forwarding the request to the internet and inspecting an initial response. The server applies certain criteria to these current conditions. If the criteria are satisfied, the server proceeds to receive the complete response from the internet and then forward the response to the requesting terminal. If the criteria are not satisfied, the current conditions are not appropriate for the user's particular request. In this case, the server caches the download code (if not already cached), sends a message to the internet to abort the request, determines when to resubmit the request in compliance with the criteria, and schedules resubmission of the download code to the internet at the determined time. If conditions warrant, the server may forego resubmission of the request.
