摘要： This invention provides methods and apparatus for enabling access to restricted information contained at a semi-trusted web-server. Restricted information is information that is only available to a selected group of authorized clients. A client desiring access to the restricted information authenticates itself with a trusted web-server, and obtains a client credential. The client then contacts the semi-trusted web-server with the credential and obtains access to the restricted content. The restricted information may be encrypted at the semi-trusted web-server, so that the restricted information is secure even if the semi-trusted web-server is not completely secure.

摘要： A method of controlling packet traffic in an IP network of originating, receiving and intermediate nodes to meet performance objectives established by service level agreements. Traffic statistics and performance data such as delay and loss rates relating to traffic flows are collected at intermediate nodes. A control server processes the collected data to determines data flow rates for different priorities of traffic. A static directory node is used to look up inter-node connections and determine initial traffic classes corresponding to those connections. The rates are combined with the initial traffic classes to define codes for encoding the headers of packets to determine their network priority.

摘要： A method, apparatus, article of manufacture and computer product for low-overhead continuous monitoring of network performance in an intranet or Internet topology. Probe packets are sent from ingress access routers where they are received and processed by egress access routers. Probe packets are generated by copying every Nth packet being sent by an ingress access router. In the event an access router does not receive the probe packet, the probe packet is discarded through normal network delivery mechanisms. Network delay is determined by subtracting the time that a probe packet was received with the time stamp enclosed in the probe packet. Round trip time is established by reflecting the probe packet back to the originating access router and computing the round trip time. Bandwidth monitoring is achieved by using the number of probe packets received to estimate the expected amount of network traffic to be received. Fault monitoring is accomplished by comparing the number of probe packets received with the number of actual packets received. When the low overhead mechanisms indicate that network delays or faults exist, a heavy weight monitoring protocol is started between two access routers in question.

摘要： A method, apparatus and system is provided by which two or more cooperating end-users of the Internet and/or other network can dynamically select and use a single Internet or other network service provider (ISP) from among a multitude of ISPs based on the application requirements. The service provider may be selected in a dynamic fashion. This overcomes the problem wherein traditionally most end-users, whether they are individuals or organizations, are connected to the Internet or other network through a single Internet and/or other network service provider. However, users generally may have more than a single connection to the Internet and/or other network. In such cases the routing of traffic over these multiple connections is handled by IP routers based on the routing information that they exchange with their peers. This information is relatively static in nature and is typically based on the state of links that interconnect the different routers. The invention provides a mechanism for the end-user to take advantage of different rates or services that might be provided by competing Internet and/or other network service providers. Furthermore, there are cases where the choice of which provider to use depends on the application. Thus this invention enables cooperating users (or sites of an organization) to dynamically select different providers on an application by application basis.
摘要翻译：提供了一种方法，装置和系统，通过该方法，装置和系统，互联网和/或其他网络的两个或多个合作的最终用户可以基于多个ISP从动态地选择和使用单个互联网或其他网络服务提供商（ISP）应用要求。可以以动态方式选择服务提供商。这克服了传统上大多数终端用户（无论是个人还是组织）通过单个因特网和/或其他网络服务提供商连接到因特网或其他网络的问题。然而，用户通常可以具有多于一个到因特网和/或其他网络的单一连接。在这种情况下，通过这些多个连接的流量路由由IP路由器根据与其对等体交换的路由信息进行处理。该信息本质上是相对静态的，并且通常基于互连不同路由器的链路的状态。本发明提供了一种用于终端用户利用可能由竞争的因特网和/或其他网络服务提供商提供的不同速率或服务的机制。此外，有些情况下，哪个供应商的选择取决于应用程序。因此，本发明使得协作用户（或组织的站点）能够通过应用程序在应用程序上动态地选择不同的提供者。

摘要： A method and apparatus for determining a referring entity for an access request for a node in a network comprises a plurality of nodes, wherein each node is identified by a unique address and each node comprises the capability for including sub-addresses. The method comprises the steps of: receiving a request for an address in the network, the request including a request for a sub-address within the node identified by the address; removing the sub-address from the request; comparing the sub-address received with a list of sub-addresses, each corresponding to a referring entity; and determining the referring entity corresponding to the request for an address based on the comparison.

摘要： The present invention is a directory server for monitoring network access requests, which includes a storage device for storing data items and an identifier associated with a monitoring node for at least a selected data item of the data items; a communication device for transmitting signals to the monitoring node; and a processing device, coupled to the storage device and the communication device. The processing device receives a network access request for the selected data item and, responsive to receipt of the request, automatically transmits a signal notifying the monitoring node of the request via the communication device, thereby enabling the monitoring node, e.g., a third party, to enforce traffic class priorities and access characteristics of the network.

摘要： A method for classifying different pages accessed by a web-browser into different service-levels on a granularity finer than that of the connection. The method augments each edge device with two applications, a Client-Proxy and a Server-Proxy. The Client-Proxy obtains identifying information from the client's request, and the obtain PICS labelling information from a label referee. This information is used to obtain a service level from an LDAP based SLA directory, and this service level information is then imbedded along with a unique identifier for the network operator organization in the HTTP header request which is transferred to the Server-Proxy. The Server-Proxy then strips the header containing the PICS information from the request and forwards the request to the server. When the Server-Proxy gets a response, it uses the PICS information to mark the packets.
