摘要： We have realized that for a connection over a large data network, such as an Internet connection that couples a web access device to a terminal server connected to a applications server, delays associated with the process of downloading large data files over such a connection, occur primarily in the leg of the connection that couples the applications server to a terminal server while little congestion is typically observed in the leg of the connection that couples the Internet access device to the terminal server. The aforementioned delay is reduced by establishing a separate connection from the applications server to the Point Of Presence server outside or independently of the backbone of the large data network thereby allowing users to receive enhanced grade of service for file transfer operations.

摘要： In order to reduce the delay and/or loss of packets caused by the transmission through a large number of routers on the Internet, a direct connection is established between a client (or its proxy) and a server if the client (or its proxy) and the server are connected to the same alternative subnetwork. Control management information, including the type of subnetwork to which each is connected, as well as the address of the client (or its proxy) and the server are transmitted to the other on the Internet in an optional HTTP header field. After receipt of the addressing information, a direct connection is established on the alternative subnetwork between the client (or its proxy) and the server for purposes of streaming information from the server to the client.

摘要翻译：我们已经意识到，对于通过将网络访问设备耦合到连接到应用服务器的终端服务器的大型数据网络的连接，发生与通过这样的连接下载大数据文件的过程相关的延迟主要是在将应用服务器耦合到终端服务器的连接中，通常在将因特网接入设备耦合到终端服务器的连接中通常观察到拥塞很少。通过在大数据网络的骨干网之外或独立于大数据网络的骨干网建立与应用服务器到存在点服务器的单独连接来减少上述延迟，从而允许用户接收用于文件传输操作的增强等级的服务。

摘要： On the Internet, different caches may contain copies of objects that have been copied from originating servers when they were accessed by users. Interconnected caches may have different objects stored thereon that might at some time be requested by a client terminal that is connected to a cache other than the one on which the object is stored. Rather than awaiting a request for a particular object and then querying each neighbor cache to determine whether a copy of the requested object is stored thereon, and then downloading the requested object if it is found, information about the contents of the neighbor caches is exchanged between these caches so that when a request for an object is received, the object can be retrieved from the cache in which it is stored. In the altemative, the object may be retrieved from the originating server if, for example, the object stored in a cache is stale based on the date and time it was last modified in the cache.
摘要翻译：在互联网上，不同的缓存可能包含当用户访问时从源服务器复制的对象的副本。互连缓存可以具有存储在其上的不同对象，其可能在某时被被连接到除了存储对象的缓存之外的高速缓存的客户终端请求。而不是等待对特定对象的请求，然后查询每个邻居缓存以确定所请求对象的副本是否被存储在其上，然后下载所请求的对象（如果被发现），则关于邻居缓存的内容的信息在这些缓存使得当接收到对象的请求时，可以从存储对象的高速缓存中检索该对象。在替代方案中，如果例如基于上次在缓存中修改的日期和时间，存储在高速缓存中的对象陈旧，则可以从始发服务器检索对象。

摘要： On the Internet (106), rather than retrieving a frequently requested Web object from its originating server (105) in response to a request from a client terminal (101, 102), the object rather can be retrieved from a cache (103) within the Internet Access Service Provider (IASP) (104), which connects the client terminal to the Internet. What is stored in the cache may, however, not be the most recent version of the object. Distinct from providing the Web object itself, information about changes to the object is provided by the server in response to a cache request that is asynchronous to a request from a client for the object. Such information about changes to an object includes the date and time when the object was last modified, the byte size of the modified object, and information on the type of content of the object. After receiving this information about changes to an object, the cache may then request that a copy of the object be downloaded to it.
摘要翻译：在互联网（106）上，响应于来自客户终端（101,102）的请求，不是从其起始服务器（105）检索经常请求的Web对象，而是可以从内部的高速缓存（103）检索对象互联网接入服务提供商（IASP）（104），其将客户终端连接到因特网。但是，缓存中存储的内容可能不是对象的最新版本。提供Web对象本身不同，服务器提供有关对象更改的信息，以响应与客户端对该对象的请求异步的缓存请求。关于对对象的更改的这种信息包括对象被上次修改的日期和时间，修改对象的字节大小以及关于对象的内容类型的信息。在接收到有关对象的更改的信息之后，缓存可以请求将对象的副本下载到其上。
