摘要： An object cache stores objects in a cyclic buffer to provide highly efficient creation of cache entries. The cache efficiently manages storage of a large number of small objects because the cache does not write objects into a file system as individual files, rather the cache utilizes cyclical buffers in which to store objects as they are added to the cache. Because of the use of a cyclic buffer, the high-overhead process of purging cache entries never needs to be performed. Cache entries are automatically purged as they are overwritten when the cyclic buffer becomes full and the input pointer wraps around from the end of a cyclic buffer to the beginning of a cyclic buffer. Additionally, in the event of a system crash or disk subsystem malfunction, inspect and repair time is independent of the size of the cache, as opposed to conventional file systems in which the time is proportional to the size of the file system.
摘要翻译：对象缓存将对象存储在循环缓冲区中以提供高效创建缓存条目。高速缓存有效地管理大量小对象的存储，因为高速缓存不将对象作为单个文件写入文件系统，而是缓存使用循环缓冲区来存储被添加到高速缓存中的对象。由于使用循环缓冲区，因此不需要执行清除高速缓存条目的高开销过程。当循环缓冲器变满并且输入指针从循环缓冲器结束循环到循环缓冲器的开始时，缓存条目被自动清除，因为它们被重写。另外，在系统崩溃或磁盘子系统发生故障的情况下，检查和修复时间与缓存的大小无关，与传统的文件系统相比，文件系统的时间与文件系统的大小成正比。

摘要： The present invention includes a method and apparatus for registering devices in a computer network. Initially, for an unregistered device, the network establishes a unregistered enabled packet filter. The unregistered enabled packet filter discards all IP packets that originate at the unregistered device, except IP packets addressed to a registration server. IP packets sent to the registration server allow a user to authenticate the unregistered device. Subsequently, the network replaces the unregistered enabled packet filter with a registered enable packet filter. The registered enabled packet filter allows the device to send packets to a login server within the computer network. Subsequently, if the user fails to pay subscription fees (of for other applicable reason) the registered enabled packet filter may be replaced with a registered disabled packet filter to prevent the device from sending packets to the network. Devices used in attacks against the network may be assigned unregistered disabled packet filter to prevent their use in subsequent attacks.
摘要翻译：本发明包括用于在计算机网络中登记设备的方法和装置。最初，对于未注册的设备，网络建立未注册启用的包过滤器。未注册启用的分组过滤器将丢弃源自未注册设备的所有IP数据包，但IP地址为注册服务器的数据包。发送到注册服务器的IP数据包允许用户对未注册的设备进行身份验证。随后，网络用已注册的启用包过滤器替换未注册启用的包过滤器。注册启用的包过滤器允许设备将数据包发送到计算机网络内的登录服务器。随后，如果用户没有支付订阅费用（对于其他适用的原因），则可以用注册的禁用分组过滤器替换已注册的分组过滤器，以防止设备向网络发送分组。用于攻击网络的设备可能被分配未注册的禁用包过滤器，以防止其在随后的攻击中使用。

摘要： A data structure for dynamically associating a service dependent representation with a servant object at run time is used in a distributed object computing system that incorporates subcontracts. Subcontracts supply different functionalities to objects. The data structure exists before run time, and is used at run time to perform the dynamic association. An arrangement also exists at run time. The structure comprises a service representation class representing a single subcontract, a servant base class associated with servant objects created at run time, and a linking mechanism to form a run time link between the server rep class and a servant object at run time. The server rep class provides functionality unique to a subcontract. At run time, servant objects are instantiated from the servant base class or a more derived class. The servant object uses the functionality provided by a subcontract by way of the linking mechanism. An arrangement exists at run time for dynamically linking a servant object to a subcontract. Included are a servant object, a server rep object, and a pointer from the servant object to the server rep object. Methods and apparatus allow a servant object itself to initiate calls to deactivate itself, to determine remaining references to itself, to revoke itself, and to get an object reference for itself. A method creates a servant object that includes the above data structures and ability to call these functions.

摘要： A method of remotely executing a computer process between a parent computer initiating the process and a child computer executing the process. In one embodiment the process includes a step of associating objects with representations having specific object bindings dependent on the site of process of execution. The same representation has a first object binding if the process is executed on the parent computer, and a second object binding if the process is executed on the child computer. The set of objects associated with these location dependent representations may include objects resident at both the parent and child computers. Additional objects may be associated with a second set of representations having object bindings dependent upon the network site of process execution to accommodate remote process executions across two or more computer networks. In an alternative embodiment, objects are associated with multiple representations in an ordered merge directory. Some of the representations within said multiple representations are also dependent on the site of remote process execution. Processes may then access objects resident at a site of process execution, or access objects resident at sites proximate the site of remote process execution.

摘要： Methods and apparatus in an object oriented programming environment for invocation of objects with interface inheritance. An object reference using mtables contains two parts, more specifically, a pointer to the data for an object and a pointer to the methods on the object. The methods on the object are represented by a collection of mtables. An mtable for a given interface consists of pointers to mtables for inherited interfaces and pointers to functions implementing the operations declared in the interface. An mtable pointer in an object reference points to an mtable for an apparent interface of the object reference. Mtables for any inherited interfaces are reached by indirection from the mtables for the apparent interface.

摘要： A method and apparatus for performing client-sensitive DNS translations includes the steps of receiving a translation request by a DNS server. The DNS server examines the translation request to determine if a record exists within the DNS server that associates the symbolic name included in the translation request with an IP record. If such a record exists, the IP address is returned as the translation. If not, the DNS server determines whether reflective client-sensitive translation is required. In the affirmative case, the request is reflected to back to the client where client-sensitive translation is performed and returned to the DNS server. If client-sensitive translation is not required, the DNS server determines whether non-reflective client-sensitive translation is required. If so, the requested translation is forwarded to a special DNS server, along with information that identifies the client system requesting translation. The special DNS server then performs the requested translation and returns the translation to the DNS server. When client-sensitive translation is not required, the DNS server performs iterative or recursive DNS translation.
摘要翻译：用于执行客户敏感DNS转换的方法和装置包括以下步骤：由DNS服务器接收转换请求。 DNS服务器检查翻译请求，以确定DNS服务器中是否存在将翻译请求中包含的符号名称与IP记录相关联的记录。如果存在这样的记录，则返回IP地址作为翻译。如果不是，DNS服务器确定是否需要反映客户敏感的翻译。在肯定的情况下，请求反映到客户端敏感翻译的客户端，并将其返回给DNS服务器。如果不需要客户敏感的翻译，则DNS服务器确定是否需要不反映客户敏感的翻译。如果是这样，请求的翻译将转发到特殊的DNS服务器，以及标识客户端系统请求翻译的信息。然后，特殊DNS服务器执行所请求的翻译，并将翻译返回给DNS服务器。当不需要客户敏感的翻译时，DNS服务器执行迭代或递归的DNS翻译。

摘要： Data structures, methods and devices for reducing computing overhead by utilizing different invocation paths for same process and different process invocations in a distributed client/server based computing system are disclosed. In one aspect of the invention, calls to a servant that do not share the same process as the requesting client are routed through a transport layer, and calls to servants that do share the same process as the requesting client are passed directly to the servant, thereby bypassing the transport layer. In another aspect of the invention, distinct remote and local method tables are provided to facilitate intelligent routing of requests. In still another aspect of the invention, the appropriate method table for an object reference is intelligently selected based upon the location of the identified object.

摘要： An embodiment of the present invention provides an efficient and robust way to facilitate interoperability between two or more processes which were initially written to execute on top of two different operating systems but instead execute on top of a third operating system. Typically, the preferred embodiment begins by launching a parent process which was initially written to execute on top of a first operating system. The preferred embodiment then obtains a context object that implements a naming graph for the parent process. The context object includes bindings between a given set of names and an associated set of objects that are specific to the first operating system. At some point during execution of the parent process, the parent process spawns a child process which was initially written to execute on top of a second operating system. Next, the parent process instantiates a copy of its context object. The parent process then performs a context merge operation which ensures that object names used by the second process are interpreted relative to a context object associated with the second operating system before (or in lieu of) being interpreted relative to the context object for the first operating system. Once the context merge operation is complete, the new context object is passed to the child process and execution of the second process begins. System calls initiated by the child process will therefore be interpreted relative to the name space for the second operating system. In this way two processes which were initially written to execute on top of two different operating systems can interoperate while executing on top of yet a third operating system.
摘要翻译：本发明的一个实施例提供了一种有效和鲁棒的方式，以促进两个或多个进程之间的互操作性，这两个或多个进程最初被写入在两个不同操作系统之上执行，而是在第三操作系统之上执行。通常，优选实施例开始于最初写入以在第一操作系统之上执行的父进程。然后，优选实施例获得实现父进程的命名图的上下文对象。上下文对象包括给定的一组名称和特定于第一个操作系统的关联的一组对象之间的绑定。在父进程执行期间的某个时刻，父进程产生一个子进程，该进程最初被写入以执行第二个操作系统的顶部。接下来，父进程实例化其上下文对象的副本。然后，父进程执行上下文合并操作，确保第二进程使用的对象名称相对于与第二操作系统关联的上下文对象相对于第一操作（或代替）相对于上下文对象进行解释系统。上下文合并操作完成后，将新的上下文对象传递给子进程，并开始执行第二个进程。因此，子进程启动的系统调用将相对于第二个操作系统的名称空间来解释。以这种方式，最初写入两个不同操作系统之上执行的两个进程可以在执行第三个操作系统之前进行互操作。

摘要： A caching server that provides faster access times for independently operating network elements. The caching server initiates information transfer and holds the requested information in its memory, instead of caching information transfer in response to user requests. The caching server preloads information from another server into its memory based on a set of predetermined criteria. Such preloading preferably occurs during low usage time, such as nighttime. The information source determines which information is described in the catalog in accordance with one of a second set of predetermined criteria. For example, the catalog may be organized according to size and the information source will organize the catalog by file size. The caching server preloads as many often-used files as will fit in its cache memory

摘要： A transparent proxy server is implemented by directing particular client packets to a proxy server that handles communications between the client and an origin server. When a client sends a packet to an origin server, a router transparently redirects the packet to the proxy server by storing the proxy server address in the destination field and the origin server address in the record route options field. The proxy server sends connection setup requests to the origin server and forwards acknowledgement packets to the client. For other requests, the proxy server determines whether the requested information is stored in the proxy server cache. If so, the information is retrieved from the cache; if not, the information is retrieved from the origin server. All acknowledgement and information packets are sent to the client with the origin server address in the source field, making it appear that the origin server sent the packets.
