    摘要： A handle administration system is described in which software agents receive handles to various resources that they can use to obtain the resources. The described embodiments provide multiple states that can be assumed by the handles. An unassigned state is provided in which handles are not assigned to a particular resource, nor can they be dereferenced to obtain pointers to any resources. An assigned state is provided in which handles are assigned to a particular resource and can be dereferenced to obtain a pointer to the resource. A suspended state is provided in which the handles are assigned to a particular resource but cannot be dereferenced to obtain a pointer to that resource.

    摘要： Disclosed are “black-box leases” that protect information consistency and that allow for information sharing in a distributed file system while hiding from a client information about other clients' use of the file system. This information hiding also allows greater concurrency because changes to the file system are permitted as long as they do not affect the leases as observed by the clients. For each data field protected by a black-box lease, a client has a two-value data structure: SelfValue represents the client's intended use of the data field, and OtherValue is an aggregation of the other clients' intended uses of that data field. Knowing only this aggregate OtherValue, but without knowing any specifics of the other clients' usage patterns, the client knows how it may use the data field without adversely affecting the consistency of data in the distributed file system.

    摘要翻译： 公开的是“黑箱租赁”，其保护信息一致性并且允许在分布式文件系统中的信息共享，同时隐藏客户端关于其他客户端使用文件系统的信息。 此信息隐藏还允许更大的并发性，因为只要不影响客户端遵守的租约，就允许对文件系统进行更改。 对于由黑盒租赁保护的每个数据字段，客户端具有两值数据结构：SelfValue表示客户端对数据字段的预期用途，而OtherValue是其他客户端该数据字段的预期用途的聚合。 只知道这个聚合的OtherValue，但是不知道其他客户端的使用模式的任何细节，客户端知道如何使用数据字段，而不会对分布式文件系统中的数据的一致性产生不利影响。

    摘要： Cryptographic protocols and methods of employing the same are described. The described protocols advantageously enable two or more identical encryptable objects that are coded for encryption with different keys to be identified as identical without access to either the unencrypted objects or the keys that are used in the encryption process. Additionally, the protocols enable two or more identical encryptable objects to be processed with different encryption keys, yet be stored in a manner so that the total required storage space is proportional to the space that is required to store a single encryptable object, plus a constant amount for each distinct encryption key. In various embodiments, the encryptable objects comprise files and the cryptographic protocols enable encrypted files to be used in connection with single instance store (SIS) systems.

    摘要翻译： 描述了使用它们的密码协议和方法。 所描述的协议有利地使得被编码用于具有不同密钥的加密的两个或更多个相同的可加密对象被识别为相同，而不访问加密过程中使用的未加密对象或密钥。 另外，这些协议允许使用不同的加密密钥来处理两个或多个相同的可加密对象，但是以一定的方式存储，使得所需的总存储空间与存储单个可加密对象所需的空间成正比，加上常数 每个不同加密密钥的数量。 在各种实施例中，可加密对象包括文件，并且加密协议使加密文件能够与单实例存储（SIS）系统相关联使用。

    摘要： Scalable leases reduce latency and reduce the burden on a server in managing data leases. Instead of processing individual lease requests for clients seeking access to the same data, scalable leases provide for blanket leases that all of the clients can use to access the selected data. Leases may be encrypted or selectively distributed to restrict access to the data. Moreover, distributed data structures may be used to cache leases at identifiable nodes in a network to offload work from the server without all clients in the network having to cache all blanket leases issued. Thresholds for issuing blanket leases may be determined or adjusted by considerations such as demand for the selected data and server workload. Similarly, leases may be renewed on the basis of demand for selected data, conflicting lease requests, and other factors. Scalable leases may be issued for read leases and controlled write leases.

    摘要翻译： 可扩展租赁减少延迟并减少服务器管理数据租赁的负担。 寻求访问相同数据的客户不需要处理单独的租赁请求，而是可扩展租赁提供所有客户端可以使用来访问所选数据的全面租赁。 租赁可以被加密或选择性地分配，以限制对数据的访问。 此外，分布式数据结构可以用于在网络中的可识别节点处缓存租约，以从服务器卸载工作，而不必网络中的所有客户端都必须缓存所有发布的全部租约。 可以通过诸如对所选择的数据和服务器工作负载的需求等考虑来确定或调整用于签发覆盖租赁的阈值。 同样，租赁可以根据对所选数据的需求，相互冲突的租赁请求等因素进行更新。 可租赁租赁可以用于租赁和受控的书面租赁。

    摘要： The claimed subject matter provides a system and/or a method that facilitates optimally and efficiently utilizing an image file format. A server can host an image that is partitioned into two or more tiles, wherein the two or more tiles collectively represent the image in entirety and are defined in at least one image file format. A tile generator can evaluate at least one tile to identify a suitable image file format based upon at least one of a characteristic of such file format or a context of a use for the tile. A browser can utilize the tile in the identified file format in order to render a portion of the image.

    摘要： Partitioned artificial intelligence (AI) for networked gaming. An exemplary system splits the AI into a computationally lightweight server-side component and a computationally intensive client-side component to harness the aggregate computational power of numerous gaming clients. Aggregating resources of many, even thousands of client machines enhances game realism in a manner that would be prohibitively expensive on the central server. The system is tolerant of latency between server and clients. Deterministic and stateless client-side components enable rapid handoff, preemptive migration, and replication of the client-side AI to address problems of client failure and game exploitation. The partitioned AI can support tactical gaming navigation, a challenging task to offload because of sensitivity to latency. The tactical navigation AI calculates influence fields partitioned into server-side and client-side components by means of a Taylor-series approximation.
