### 特征比对表格

技术特征描述及公开性判断对比文件原文引用公开性论述
**技术特征A:**《隐含公开》<br>所述系统的特征在于用于客户端所布置的内容块的存储部件(23、S2)和逻辑部件(25a-c、26a-c)被分离到不同的物理主机(6、7、9A、9B)中[p0091] “...the gateway 408 checks whether the requested file is stored in the cache. If the requested is cached the gateway node 408 responds immediately with the requested file 708 but if the file is not cached the gateway selects a source for the requested file...The file 712 is then retrieved from this P2P node, stored within the cache, and then served 708 to the requesting user node 410.”<br><br>[p0085] “Initially user node 410 issues a query 700 which is received by P2P gateway 408.”对比文件公开了P2P网关408,其包含缓存(存储部件)并能够处理P2P协议消息(如接收查询700)。用户节点410发起查询和下载请求,这体现了它运行着P2P客户端逻辑(逻辑部件)。当用户节点410请求文件时,若文件已被缓存在网关408中,则由网关直接提供,这实质上实现了:用户节点410执行P2P搜索和请求的逻辑,而内容块的存储则由物理上分离的网关408来承担。虽然对比文件未使用“分离到不同物理主机”的明确表述,但通过其网络架构图(如图5)和功能描述,本领域技术人员可以合理推断出,为了优化流量,客户端逻辑(位于PC 410)和存储内容(位于网关408的缓存)被分别部署在了不同的物理设备上。这隐含了逻辑部件和存储部件可分离的思想。
**技术特征B:**《直接公开》<br>由此安排所述客户端(1-6)使得中央节点(7)位于外部客户端(2,3,4)与内部客户端(1,5,6)之间的信令路径上[p0021] “The gateway resides at the boundary of a service providers network to facilitate control of traffic from the one network portion that is, for example, the first network portion managed by, say, an ISP and the other network portion, in this example the second network portion, comprising, say, the rest of the world. By routing peer-to-peer messages, preferably all peer-to-peer messages intended for the other network portion, via the gateway...”<br><br>[p0064] “All P2P requests are routed through gateway node 408 and attempts to connect to nodes outside the ISP's network results in connections to the gateway node.”对比文件明确指出,网关节点408位于ISP网络(相当于内部网络)的边界,所有流向外部网络(即“世界的其余部分”)的P2P消息都会被路由经过该网关。这直接描述了网关节点408在物理和逻辑上均位于内部客户端(ISP网络内的节点)和外部客户端(ISP网络外的节点)之间的必经信令路径上,其功能与目标专利中的中央节点(7)一致。
**技术特征C:**《隐含公开》<br>其中所述中央节点(7)主管用于所述内容块的逻辑设施[p0093] “...at step S802 and checks whether it is able to respond from the cache. If gateway 408 is able to respond from the cache it does so at step S804...However if the gateway is unable to respond directly it relays the query to its intended destination at step S806 and then waits to receive a query hit response...The gateway node then checks, at step S810, whether the one or more hash values received at step S808 are in the cache table...”<br><br>[p0096] “At step S900 the gateway node 408 receives a user download (GET) request and at step S902 checks whether the request includes a hash value...Then, at step S908 this procedure checks whether the request is filed within the cache and if so serves the file to the requesting node from the cache (step S910)...”对比文件中的网关408不仅仅是缓存(存储),它还执行复杂的P2P逻辑操作。例如,它接收查询、检查缓存、决定是否自己响应或转发查询、修改查询命中消息、拦截下载请求并从缓存或外部源提供文件。这些行为(查询处理、决策、消息重写、请求拦截和响应)构成了P2P内容共享的核心逻辑。因此,网关408主管了处理内容块请求和分发的逻辑设施,这与目标专利中“中央节点主管逻辑设施”的方案在本质上是相同的。
**技术特征D:**《隐含公开》<br>至少一个内部客户端(1,5,6)主管用于所述内容块的存储设施(S1、S2)[p0086] “If this query includes a hash value for a requested file the gateway may be able to respond immediately with a query hit 702 specifying a location for the file, either in the cache or **in some other location, preferably within the ISP's network**.”<br><br>[p0090] “...the gateway selects a source for the requested file using the source table of data store 608...The file 712 is then retrieved from this P2P node, stored within the cache, and then served 708 to the requesting user node 410.”对比文件明确指出,请求的文件可以位于ISP网络内的“其他位置”,并且网关可以从其他P2P节点(这些节点通常运行在内部客户端上)检索文件。这隐含了内部网络中的用户节点(内部客户端)可以作为文件内容的存储提供者。例如,一个内部客户端PC可以共享文件,其存储设施(硬盘)主管着内容块。当其他客户端请求该内容时,网关可以从这个内部客户端下载。这与内部客户端主管存储设施的特征相符。
**技术特征E:**《直接公开》<br>所述中央节点(7)中的部件适用于从第一请求内部客户端(1)接收对内容块的请求(41)[p0085] “Initially user node 410 issues a query 700 which is received by P2P gateway 408.”<br><br>[p0093] “Thus at step S800 the gateway 408 receives a P2P query...”对比文件明确记载了P2P网关408接收来自用户节点410的P2P查询消息。该用户节点410位于ISP网络内部,即为“内部客户端”。查询消息即为对内容(文件)的请求。因此,网关中包含用于接收内部客户端请求的部件。
**技术特征F:**《直接公开》<br>在所请求的内容的处置中转发(42)适用于外部客户端(2)的所接收的请求的部件[p0093] “However if the gateway is unable to respond directly it **relays the query to its intended destination** at step S806...”<br><br>[p0064] “All P2P requests are routed through gateway node 408 and attempts to connect to **nodes outside the ISP's network** results in connections to the gateway node.”对比文件公开了当网关408无法从缓存响应时,它会将查询消息“中继到其预期目的地”。由于所有去往ISP外部节点的流量都经过网关,因此这个“预期目的地”通常就是外部客户端。这直接描述了网关接收内部客户端的请求,并将其转发给外部客户端的功能。
**技术特征G:**《直接公开》<br>所述中央节点(7)中的部件适用于从所述外部客户端(2)接收所请求的内容块[p0093] “...then waits to receive a query hit response including one or more file hash values at step S808.”<br><br>[p0086] “...query is relayed...to a remote P2P node...a query hit 704 in response to query 700 is relayed back to P2P gateway 408.”对比文件公开了网关在转发查询后,会从远程P2P节点(外部客户端)接收一个查询命中响应。随后,在图9的流程中,网关会基于此向外部源发起GET请求并下载文件([p0091]的“The file 712 is then retrieved from this P2P node”)。这个过程直接表明网关具备从外部客户端接收所请求内容块的能力和部件。
**技术特征H:**《直接公开》<br>所述中央节点中的部件适用于转发(44)所述块到所述第一请求内部客户端(1)[p0091] “The file 712 is then retrieved from this P2P node, stored within the cache, and **then served 708 to the requesting user node 410**.”<br><br>[p0096] “...if so **serves the file to the requesting node from the cache** (step S910)...”对比文件明确公开了网关408在获取文件(无论是从外部节点获取还是从缓存中获取)后,会将其“提供给请求的用户节点410”。该用户节点410是发起最初请求的内部客户端。这直接对应于将内容块转发给第一请求内部客户端的功能。
**技术特征I:**《隐含公开》<br>所述中央节点(7)中的部件适用于转发(46)所述内容块到所述内部客户端(5,6)的至少一个所主管的存储设施(S2)[p0091] “The file 712 is then retrieved from this P2P node, **stored within the cache**, and then served 708 to the requesting user node 410.”对比文件公开了网关从外部节点下载文件后,会将其“存储在缓存中”。这个缓存可以看作是网关自身主管的一个存储设施。但更广义地看,对比文件提到文件源可以是“在ISP网络内的其他位置”([p0086]),这表明网络内存在多个由内部客户端主管的存储设施。网关通过其“源表”(Source Table)管理这些位置,暗示了网关可以将热门内容主动推送或复制到这些边缘存储设施,以优化后续请求。虽然对比文件未明确描述“主动转发到特定内部客户端主管的存储设施”这一信令步骤,但其缓存管理和多源选择的机制,为本领域技术人员提供了推断出此方案的基础,即为了实现更优的流量管理,网关可以将内容块传输并存储到网络边缘某个选定的内部节点(即其主管的存储设施)中。
**技术特征J:**《隐含公开》<br>所述系统还包括[p0095] “Figure 9 shows a flow diagram of a procedure for handling a user download request received from a node such as user node 410.”技术特征J是一个引子,其本身不包含技术内容,而是引出后续的特征K和L。对比文件中存在处理用户下载请求的完整流程(图9及其描述),该流程的开始自然包含了“系统还包括”进行后续判断和处理的部件这一概念。
**技术特征K:**《隐含公开》<br>所述中央节点(7)中的部件适用于做出存储判定(45)[p0090] “...if the file is not cached the gateway selects a source for the requested file...The file 712 is then retrieved from this P2P node, **stored within the cache**, and then served 708...”<br><br>[p0096] “Then, at step S908 this procedure checks whether the request is filed within the cache and **if not**...at step S920, the gateway connects to the identified source and downloads the requested file, **saving it in the cache**...”对比文件公开了网关在收到下载请求时,会检查文件是否在缓存中。若不在,网关会从外部源下载文件,并将其“保存在缓存中”。这个“检查-下载-保存”的过程,本质上是一个隐式的存储判定:即“当前请求的文件,值得在本地缓存中保存一份副本”。虽然未明确描述一个独立的、基于阈值的判定模块,但其作为缓存系统的必然组成部分,隐含了存在这样一个判定逻辑来决定是否对通过网关的内容执行存储操作。
**技术特征L:**《隐含公开》<br>所述存储判定适用于将对于所述内容块的请求速率考虑在内[p0097] “It will be appreciated that even when the gateway node is unable to read the network search traffic...where the download request includes a hash value a file may be served to the requester from the cache to **significantly reduce at least download traffic on the P2P network**.”缓存技术的核心目的是将频繁访问的热门内容存储在本地,以减少重复下载的流量。对比文件明确指出其缓存功能是为了“显著减少P2P网络上的下载流量”。一个缓存要有效减少流量,其存储判定逻辑必然倾向于存储那些请求频率高(即请求速率高)的流行内容。垃圾收集机制(如[0082]提到的“time value to provide a timeout for deleting old files”)也暗示了访问频率是保留/删除判定的关键因素。因此,该特征被隐含公开。
**技术特征M:**《隐含公开》<br>所述系统还包括[p0095] “Figure 9 shows a flow diagram of a procedure for handling a user download request...”技术特征M是一个引子,其本身不包含技术内容,而是引出后续的特征N、O、P。对比文件中存在处理来自其他内部客户端请求的完整流程,该流程的开始自然包含了“系统还包括”处理后续请求的部件这一概念。
**技术特征N:**《直接公开》<br>所述中央节点(7)中的部件从第二请求内部客户端(5)接收对所述内容块的请求(47)[p0085] “Initially user node 410 issues a query 700 which is received by P2P gateway 408.”<br><br>[p0095] “Figure 9 shows a flow diagram of a procedure for handling a user download request received from a node such as user node 410.”对比文件描述了网关接收和处理来自用户节点的查询和下载请求的通用流程。虽然未用“第一”、“第二”来区分客户端,但该流程明确适用于任何发出请求的用户节点。因此,当系统中存在另一个内部客户端(第二请求内部客户端)对同一内容块发起请求时,网关同样会接收到该请求,这直接公开了接收来自其他客户端请求的部件。
**技术特征O:**《直接公开》<br>所述中央节点(7)中的部件指示(48)拥有所请求的块的存储设施(S2)输送所存储的内容[p0086] “If this query includes a hash value for a requested file the gateway may be able to respond immediately with a query hit 702 **specifying a location for the file, either in the cache or in some other location, preferably within the ISP's network**.”对比文件指出网关可以通过查询命中消息,为请求者指定一个文件位置,该位置可以是ISP网络内的“其他位置”。当这个“其他位置”是一个由内部客户端主管的存储设施时,网关发送一个指定该位置的查询命中消息,其效果等同于指示该存储设施向请求客户端输送内容。网关通过信令(查询命中)来调度内容分发,直接实现了“指示拥有块的存储设施输送内容”的功能。
**技术特征P:**《直接公开》<br>所述存储设施(S2)中的部件将所述内容输送(49)到所述第二请求客户端(5)[p0086] “...a location for the file, either in the cache or **in some other location, preferably within the ISP's network**.”<br><br>[p0064] “This facilitates a high level of interconnectivity within the ISP's network...”对比文件公开了内容可以来源于ISP网络内的“其他位置”(例如其他内部客户端)。当请求者(第二请求客户端)收到网关发送的查询命中,其中指明了这个“其他位置”后,P2P协议的下一步即是请求者直接向该位置发起HTTP GET请求以下载文件。该“其他位置”(作为存储设施)响应此请求并将内容输送给请求客户端,是P2P文件共享的标准流程。对比文件描述的架构支持并促进了这种内部互联,因此该特征被直接公开。
**技术特征Q:**《隐含公开》<br>由此所述客户端(1-6)以树结构来安排[p0007] “More sophisticated P2P networks may include "supernodes" or "ultrapeers" each with a plurality of "leaf' nodes...”<br><br>[p0064] “This facilitates a high level of interconnectivity within the ISP's network and a small number of fixed connections...crossing the expensive ISP boundary.”对比文件提到了具有“超级节点”和“叶节点”的分层P2P网络结构,这本身就是一种树状拓扑。此外,对比文件描述的网关节点作为连接内部网络和外部网络的唯一通道,所有内部节点都通过它与外部通信,形成了一种以网关为根(或父节点),内部客户端为叶子的星型或树型逻辑结构。这种安排隐含了客户端之间以树结构进行组织的可能性。
**技术特征R:**《隐含公开》<br>所述中央节点(7)是对于所述树中外部客户端(2,3,4)的常规节点[p0064] “...a small number of fixed connections, for example eight, **crossing the expensive ISP boundary 406**.”<br><br>[p0023] “In the preferred embodiment the gateway comprises **an active peer-to-peer node** of the peer-to-peer network.”对比文件指出网关是一个“活跃的P2P节点”。当它通过几条固定的连接与外部网络中的节点通信时,对于这些外部节点而言,网关408就像一个普通的对等体(常规节点),与它们交互、查询、下载文件。网关并不需要对外表现为一个特殊的控制节点,而是以标准P2P协议参与网络。这隐含了网关在外部客户端视角下,扮演着一个常规节点的角色。
**技术特征S:**《隐含公开》<br>也是对于所述树中内部客户端(1,5,6)的父节点[p0064] “All P2P requests are routed through gateway node 408 and attempts to connect to nodes outside the ISP's network results in connections to the gateway node. This facilitates a high level of interconnectivity within the ISP's network...”<br><br>[p0034] “...the gateway may respond to the message.”对比文件公开了所有内部客户端发往外部网络的P2P请求都流经网关,并且网关可以直接响应这些请求。在逻辑拓扑上,网关成为了内部客户端访问外部P2P资源的唯一代理和上级节点。内部客户端不直接与外部节点交互,而是通过网关进行,这种集中式的转发和代理关系,使得网关在功能上充当了所有内部客户端的“父节点”。
**技术特征T:**《直接公开》<br>由此所述中央节点(7)位于运营商网络的边缘处[p0021] “The gateway **resides at the boundary** of a service providers network...”<br><br>[p0064] “...gateway node 408 comprising an active node on the network which acts as a gatekeeper **at the edge of the ISP's network** 402.”对比文件多处使用“boundary(边界)”和“at the edge of the ISP's network(在ISP网络边缘)”来描述网关节点408的位置,这与“位于运营商网络的边缘处”的特征完全相符,构成直接公开。
**技术特征U:**《直接公开》<br>由此所述内部客户端(1,5,6)可经所述运营商网络来访问[p0078] “...a plurality of computers 410, typically personal computers are coupled via a network 412 to a router 414, network 412 and router 414 typically comprising part of an ISP's network infrastructure.”<br><br>[p0060] “...nodes **within a network 402 managed by a service provider**...”对比文件明确指出用户节点(如PC 410)通过ISP的网络基础设施(如网络412)连接。这些节点被描述为“在服务提供商管理的网络内”。这表明内部客户端属于并可通过该运营商网络进行访问。
**技术特征V:**《直接公开》<br>所述外部客户端(2,3,4)可经所述运营商网络外的网络来访问[p0060] “...others of which are located **elsewhere in the Internet 404**.”<br><br>[p0064] “All P2P requests are routed through gateway node 408 and attempts to connect to **nodes outside the ISP's network** results in connections to the gateway node.”对比文件将非ISP网络的部分称为“Internet 404”或“ISP网络外的节点”,并明确指出网关管理与这些外部网络的连接。这表明外部客户端存在于运营商网络之外,并通过外部网络(如互联网)进行访问。
**技术特征W:**《隐含公开》<br>其中所述中央节点(7)是运营商控制的实体[p0064] “The effect of introducing a gateway node 408...which acts as a gatekeeper at the edge of the ISP's network 402.”<br><br>[p0075] “...the gateway node also stores data based upon the search traffic...This enables it to build up a database...This information may then be used for intelligent routing and caching...”对比文件中的网关节点408被部署在ISP网络的边缘,执行流量管理、缓存、内容过滤等策略,其目的是为了降低ISP的网络成本。这些复杂的、服务于网络整体利益的功能(如“智能路由和缓存”)通常需要由网络管理者(即运营商)来部署和控制,而不是由终端用户随意设置的。因此,其性质隐含了它是一个运营商控制的实体,而非普通的用户节点。
