摘要： A Private Network Access Point (PNAP) packet switched network is provided where two customers connected to the same PNAP exchange traffic through the PNAP without transiting over the backbones of the Internet. In addition, a multi-homed customer connected to the PNAP is provided with access to the PNAP optimized routing table so that the customer will also have the ability to know the best route for a particular destination. In this way, if a multi-homed customer connected to a particular National Service Provider (NSP) to which a destination is also connected, the PNAP customer can use the PNAP information regarding the NSP to send the information to the destination through that commonly connected NSP in the most direct fashion.

摘要： A method and system for pointing a Internet user requesting access to content on a particular web site to one of a plurality of content servers associated with that web site based on one or more cost measurements associated with serving said content. The identification of the web site is mapped to the content servers associated with that web site. The user's IP address is then mapped to a particular content server based on a cost function and the IP address of the selected content server is provided to the user.

摘要： An improvement to the Private Network Access Point (PNAP) packet switched network described in U.S. Pat. No. 6,009,081, where two customers connected to the same PNAP will exchange traffic through the PNAP without transiting over the backbones of the Internet. In addition, a multi-homed customer connected to the PNAP is provided with access to the PNAP optimized routing table so that the customer will also have the ability to know the best route for a particular destination. In this way, if a multi-homed customer connected to the PNAP is directly connected to a particular NSP to which a destination is also connected, the PNAP customer can use the PNAP information regarding the NSP to send the information to the destination through that commonly connected NSP in the most direct fashion.

摘要： A method and system for optimizing routing traffic to a destination when multiple routes are available. A performance monitoring and inference component measures the performance of the available paths to a large set of subnetworks, and uses those measurements to infer the performance of all available paths to an even larger set of subnetworks. A routing optimization component uses a cost function that assigns a cost to a routing table based on information from the performance monitoring and inference component, as well as other path characteristics, and further uses a minimization methodology to find a routing table with a very low cost, as defined by the cost function. A BGP bridge takes the routing table generated by the routing optimization component and communicates that information to the routers using BGP, thereby ensuring that the routers will route traffic in accordance with the routing table.
摘要翻译：一种用于在多个路由可用时优化到目的地的路由流量的方法和系统。性能监视和推理组件测量到大量子网络的可用路径的性能，并使用这些测量来推断所有可用路径到更大子网组的性能。路由优化组件使用成本函数，其基于来自性能监视和推理组件的信息以及其他路径特性为路由表分配成本，并且还使用最小化方法来以非常低的成本找到路由表，由成本函数定义。 BGP桥接器采用路由优化组件生成的路由表，并使用BGP将该信息传递给路由器，从而确保路由器根据路由表路由流量。

摘要： A method for interconnecting P-NAP customers with P-NAP providers and symmetrically routing packets between a P-NAP customer and a destination within a P-NAP provider's backbone across the P-NAP and that provider's backbone or symmetrically routing packets between a P-NAP customer and a destination not currently within a P-NAP provider's backbone across the P-NAP and a pre-defined P-NAP provider's backbone known as the default backbone. The method comprises creating a list of all P-NAP provider AS numbers and a list of all AS numbers which peer at public NAPs but which are not associated with P-NAP providers. For each P-NAP provider, take the union of all provider AS numbers and AS numbers associated with public NAPs and subtracting out AS numbers associated with the current provider. Deny that resulting list of AS numbers on routes as they are received from the current provider to approximate the routes which are deemed to be destined within the current provider's network by tagging these routes with the primary local preference value. For all routes which were denied, attach the secondary local preference value. Set P-NAP provider local preferences causing the P-NAP provider to select direct routing from the P-NAP provider to the P-NAP. Make changes to AS path lengths of routes advertised by the P-NAP to each P-NAP provider to cause providers not directly connected to the P-NAP to use the same preselected P-NAP provider as the P-NAP uses to send to the providers.
摘要翻译：一种将P-NAP客户与P-NAP提供商互连并在P-NAP提供商的骨干网内的P-NAP客户与目的地之间对称地路由数据包的方法，用于P-NAP和该提供商的主干，或者在P- NAP客户和P-NAP提供商目前不在P-NAP中的骨干网和预定义的P-NAP提供商的骨干网，被称为默认骨干网。该方法包括创建所有P-NAP提供商AS号码的列表以及与公共NAP对等但是不与P-NAP提供商相关联的所有AS号码的列表。对于每个P-NAP提供商，采用与公共NAP相关联的所有提供商AS号码和AS号码的并集，并减去与当前提供商相关联的AS号码。拒绝从当前提供商接收到的路由上的AS号的结果列表，以通过使用主本地优先级值标记这些路由来近似在当前提供商的网络内被认为是注定的路由。对于被拒绝的所有路由，请附加辅助本地优先级值。设置P-NAP提供商本地偏好，导致P-NAP提供商选择从P-NAP提供商到P-NAP的直接路由。将由P-NAP发布的路由的AS路径长度更改为每个P-NAP提供商，以使未直接连接到P-NAP的提供商使用与P-NAP用于发送到P-NAP的相同的预选P-NAP提供商提供者
