摘要： An information object repository is configured to resolve a network layer anycast address to a network layer unicast address in response to a request for an information object at the network layer anycast address. The information object repository may be further configured to resolve the network layer anycast address by transmitting a request for the network layer unicast address and awaiting a response thereto, and, in some cases, to return a failure message to a source of the request for the information object if the response to the request for the network layer unicast address is not received within a timeout period. Preferably, the request for the network layer unicast address is a single IP packet that includes the network layer anycast address. Similarly, the request for the network layer unicast address is preferably a single IP packet that includes the network layer unicast address. The response to the request for the network layer unicast address may be returned by a host having the network layer unicast address, or another network node configured to do so.

摘要： Various information object repository selection procedures for determining which of a number of information object repositories should service a request for the information object include a direct cache selection process, a redirect cache selection process, a remote DNS cache selection process, or a local DNS cache selection process. Different combinations of these procedures may also be used. For example different combination may be used depending on the type of content being requested. The direct cache selection process may be used for information objects that will be immediately loaded without user action, while any of the redirect cache selection process, the remote DNS cache selection process and/or the local DNS cache selection process may be used for information objects that will be loaded only after some user action.

摘要： A request for an information object at an address identified by a uniform resource locator (URL) is received; and the URL is mapped to a corresponding unicast address for the information object. Thereafter, the unicast address for the information object may be used as an anycast address.

摘要： A set of access control labels is assigned to each of a number of users of a caching infrastructure in a network. The labels are used in specifying access control lists for content of the users. Requests for the content are referred to selected information object repositories of the caching infrastructure without regard as to whether the content is actually stored at the information object repositories; and access to the content is controlled according to access lists developed according to the access control labels. Access to the content may be controlled by comparing information included in uniform resource locators (URLs) to the access control lists. Such information may be one or more digital signatures, for example, which identify one or more of: the source of the requests, and an owner of an information object being requested. The access control lists are preferably maintained corresponding to the access control labels, which may be hierarchical in nature. Each of the information object repositories of the caching infrastructure may store a copy of each of the access control lists. Access to content is denied if a request therefor is not authorized, otherwise, the content is returned to a requester thereof.

Requests for the content are referred to selected information object repositories of the caching infrastructure without regard as to whether the content is actually stored at the information object repositories; and access to the content is controlled according to access lists developed according to the access control labels. Access to the content may be controlled by comparing information included in uniform resource locators (URLs) to the access control lists.

The access control lists are preferably maintained corresponding to the access control labels, which may be hierarchical in nature. Each of the information object repositories of the caching infrastructure may store a copy of each of the access control lists. Access to content is denied if a request therefore is not authorized, otherwise, the content is returned to a requestor thereof.
摘要翻译：一组访问控制标签被分配给网络中的缓存基础设施的多个用户中的每一个。这些标签用于指定用户内容的访问控制列表。对内容的请求被引用到高速缓存基础设施的选定的信息对象库，而不考虑内容实际上是否存储在信息对象存储库中; 并且根据访问控制标签开发的访问列表来控制对内容的访问。可以通过将统一资源定位符（URL）中包括的信息与访问控制列表进行比较来控制对内容的访问。这样的信息可以是一个或多个数字签名，例如，其识别请求的来源和被请求的信息对象的所有者之一或多个。访问控制列表优选地对应于访问控制标签来维护，访问控制标签本质上可以是分层的。缓存基础设施的每个信息对象存储库可以存储每个访问控制列表的副本。如果请求因此未被授权而拒绝对内容的访问，否则将内容返回给其请求者。

摘要翻译：信息对象存储库被配置为响应于对网络层任播地址处的信息对象的请求，将网络层任播地址解析为网络层单播地址。信息对象库可以被进一步配置为通过发送对网络层单播地址的请求并等待对其的响应来解析网络层任播地址，并且在某些情况下，将故障消息返回到请求的源信息对象如果在超时时间段内没有收到对网络层单播地址请求的响应。优选地，对网络层单播地址的请求是包括网络层任播地址的单个IP分组。类似地，网络层单播地址的请求优选地是包括网络层单播地址的单个IP分组。对网络层单播地址的请求的响应可以由具有网络层单播地址的主机或被配置为这样做的另一网络节点返回。
