摘要： Each network node having at least one destination-oriented link toward a directed acyclic graph (DAG) destination can receive a corresponding set of path performance metrics via the destination-oriented link. The set of path performance metrics, initiated by the DAG destination outputting initial link metrics on each of its source-connecting links, identifies aggregate link metrics for a corresponding path to the DAG destination via the corresponding destination-oriented link. The network node outputs a corresponding updated set of path performance metrics on each of its source-connecting links based on the received set of path performance metrics and the corresponding link metric for the corresponding source-connecting link. Hence, each network node in the DAG can assess the performance of each connected path to the DAG destination, and forward a data packet via a selected destination-oriented link based on the corresponding path performance metrics and forwarding policies for the forwarded data packet.

摘要： A network includes network nodes and a gateway. Each network node has a corresponding unique in-site IPv6 address for communication within a prescribed site, each in-site IPv6 address having a first IPv6 address prefix that is not advertised outside of the prescribed site. Network nodes can obtain from within the prescribed site a unique extra-site IPv6 address for mobile or extra-site communications. The extra-site IPv6 address has a second IPv6 address prefix, distinct from the first IPv6 address prefix, advertised by the gateway to the prescribed site and the wide area network. The gateway establishes a secure connection (e.g., tunnel) with each corresponding IPv6 node using its corresponding extra-site IPv6 address, and creates a corresponding binding cache entry specifying the corresponding extra-site IPv6 address and in-site IPv6 address. Hence, the gateway provides wide area network access while maintaining secrecy of the in-site IPv6 addresses.

摘要： The invention allows a system to prevent robots from browsing a Web site beyond a welcome page. When an initial request from an undefined originator is received Web site responds to it with a welcome page including at least one trap. Then, on receiving further requests from the undefined originator Web site can check whether a trap is used or not. If not used the undefined originator is assumed to be a human being and is authorized to go on. If a trap is however used the undefined originator is assumed to be a robot in which case site access is further denied. The invention prevents Web site contents from being investigated by robots while not requiring users to have to log on.

摘要： A method and system are disclosed for dynamically assigning, on a Local Area Network, through a mediator, a plurality of active routers to a plurality of hosts so as to handle hosts data packets destined to remote users not connected on the LAN. Because hosts know only the address of the mediator they must first go through it for being assigned a particular router. When receiving the first request, mediator selects one router among those of the routers that are active and informs the host which may then forward the first packet and all subsequent ones to the selected router. The same is done for each host connected on the LAN. After which mediator is free to reassess the router to host assignment any time if significant changes are observed such as the failure of a router, the removing or the addition of a router to the pool of routers or a drastic modification of the host generated traffic.
摘要翻译：公开了一种用于在局域网上通过中介器将多个活动路由器动态地分配给多个主机以便处理去往未连接在LAN上的远程用户的主机数据分组的方法和系统。因为主机只知道调解员的地址，所以他们必须首先通过它来分配一个特定的路由器。当接收到第一个请求时，调解员在有效的路由器中选择一个路由器，然后通知主机，然后可以将第一个数据包和所有后续数据转发到所选的路由器。对于连接在LAN上的每个主机也是这样。之后，如果观察到重大变化（例如路由器故障），路由器删除或添加到路由器池或主机生成的流量的剧烈修改，则可以随时重新评估路由器来主机分配。

摘要： In one embodiment, a particular device (e.g., switch) receives a neighbor discovery (ND) message from a non-trusted non-switch device, the ND message having an associated address, and creates a corresponding binding entry for the address in a temporary tentative state without forwarding the ND message. In addition, the switch then generates and forwards a first duplicate address detection (DAD) message on behalf of the non-trusted non-switch device. In response to receiving a second DAD message from a non-owner device, the switch may either drop the second DAD message when a corresponding second address of the second DAD message is stored as a tentative-state entry, or else forward the second DAD message to a corresponding owner device of the second address for neighbor advertisement (NA) defense when the second address is not stored as a tentative-state entry.

摘要： Packets may be forwarded between realms employing private unregistered addresses without the use of network address translation and/or application level gateways. Nodes within privately addressed realms are identified by a combination of their locally significant address and a globally significant realm address. The globally significant addresses are reserved in all realms for use as realm identifiers or inter-realm routing. To send a packet to a node within a distinct private realm, the packet is given an inner IP header designating the locally significant destination IP address of the target node within the remote realm and an encapsulation IP header indicating the globally significant address advertised by the gateway of the target node's realm. The globally significant address is used for forwarding outside the realm of the destination node. Once the packet reaches the destination realm, the locally significant address is used for forwarding.
