摘要： Disclosed are, inter alia, methods, apparatus, computer-storage media, mechanisms, and means associated with determining and distributing routing paths for nodes in a network. For each route computational node of multiple route computational nodes in a network: a tree of paths between itself and each of multiple nodes in the network is determined. A particular tree of paths is determined for a particular node of these multiple nodes to the other nodes based on at least two of the determined trees of paths for the route computational nodes. The particular node then sends a packet towards a destination based on the particular tree of paths determined for the particular node.

摘要： In a client-server environment, a method and system are disclosed for granting transparency to the compulsory gateway of an IP network versus client applications run by the end-users connected on the IP network. When client applications have to access, on request of the end-users, server applications beyond the compulsory gateway this latter acts on behalf of them to access the requested remote resources eventually, relaying data between client and server applications. This is achieved without requiring any personalization on client end thus, guarantees that since gateway is becoming transparent to client applications all improvements and modifications brought to the IP network actually fully benefit to all end-users.
摘要翻译：在客户机 - 服务器环境中，公开了一种方法和系统，用于向IP网络的强制网关与由IP网络上连接的最终用户运行的客户端应用提供透明度。当客户端应用程序必须根据最终用户的请求访问超出强制网关的服务器应用程序时，后者将代表它们访问最终访问请求的远程资源，并在客户端和服务器应用程序之间中继数据。这样做不需要在客户端进行任何个性化，因此，保证由于网关对客户端应用程序变得透明，所有对IP网络的改进和修改实际上完全有益于所有终端用户。

摘要： Flexible migration from IPv4 to IPv6 is facilitated for the Internet and other data networks employing Internet Protocol. In one implementation, certain IPv4 nodes are enhanced by use of a dual address including a globally significant realm address and a locally significant address used only within a particular realm. This dual IPv4 address may be readily mapped to or from an IPv6 address. The enhancement and address mapping scheme may be used to automatically tunnel IPv6 packets through IPv4 infrastructure and to use enhanced IPv4 nodes to contact IPv6 infrastructure.
摘要翻译：互联网和采用互联网协议的其他数据网络，有助于从IPv4到IPv6的灵活迁移。在一个实现中，某些IPv4节点通过使用双地址来增强，该双重地址包括仅在特定领域内使用的全局有效领域地址和本地有效地址。这个双IPv4地址可以很容易地映射到IPv6地址或从IPv6地址映射。增强和地址映射方案可用于通过IPv4基础设施自动隧道IPv6数据包，并使用增强型IPv4节点来联系IPv6基础架构。

摘要： In one embodiment, a node (e.g., a router) performs reservations for data flows, each on a corresponding selected (reserved) path having adequate reservation availability. Also, the node forwards data from data flows, each over a corresponding selected (forwarded) path having adequate load availability, wherein forwarded paths are decoupled from reserved paths for the data flows.

摘要： According to various aspects of the present invention, a technique is described for improving load balancing of traffic in a data network using source-side related information embedded into the destination IP address field of packets received at a load balancing device. One aspect of the present invention relates to assigning more than one virtual IP address to a server cluster in order to enable different clients to select a virtual cluster address which corresponds to each clients' respective rights and/or profiles, and to use the selected virtual cluster address to access a desired site or service. Another aspect of the present invention relates to a mechanism which allows for load balancing operations to be implemented using source-side information which is embedded into the destination IP address of a packet header. In this way, load balancing decisions may be quickly performed at initial or early stages of a connection flow.

摘要： Methods and apparatus for processing registration requests by a Home Agent supporting Mobile IP are disclosed. A registration request is received from each of a plurality of Mobile Nodes, the registration request specifying a care-of address. A binding is established between each of the plurality of Mobile Nodes and the associated care-of address, each of the plurality of Mobile Nodes being associated with one another. For instance, the plurality of Mobile Nodes may be statically or dynamically assigned the same Home Address. A tunnel is then created between the Home Agent and the care-of address for each of the plurality of Mobile Nodes, thereby enabling a server request to be distributed by the Home Agent to one of the plurality of Mobile Nodes via the associated tunnel. For instance, a server request addressed to the Home Address may be forwarded to one of the Mobile Nodes assigned that Home Address.

摘要： Mobile routers in a tree-based network topology with a single clusterhead in an ad hoc network establish connectivity based on each attached mobile router sending a neighbor advertisement message to an attachment mobile router via a corresponding egress interface. Any neighbor advertisement message received by a mobile router is used to identify specified network prefixes that are reachable via the source of the neighbor advertisement message. Each attached mobile router outputs to its attachment router another neighbor advertisement message that specifies the network prefix used by the mobile router, and the specified network prefixes from its attached mobile routers. The mobile router also identifies peer mobile routers having the same depth, and selectively shares limited routing information with the peer routers, enabling the mobile router to bypass the clusterhead and reach remote prefixes via the peer routers without burdening the tree.

摘要： In one embodiment, a device (e.g., switch or registry) maintains a binding table for all internet protocol (IP) addresses in a particular subnet associated with the device, and in response to receiving a neighbor solicitation (NS) lookup message from a router for a particular address, determines whether the particular address is within the binding table. When the particular address is not within the binding table, the device causes the router to not store the particular address in a neighbor discovery (ND) cache at the router (e.g., by responding to clear the cache, or ignoring to prevent state from being created). In another embodiment, the ND-requesting router ensures that the particular address is not kept in an ND cache at the router in response to the device indicating that the particular address is not within its binding table (e.g., an explicit response to clear, or absence of instruction to store state).
摘要翻译：在一个实施例中，设备（例如，交换机或注册表）维护与设备相关联的特定子网中的所有互联网协议（IP）地址的绑定表，并且响应于从路由器接收到邻居请求（NS）查找消息对于特定地址，确定特定地址是否在绑定表内。当特定地址不在绑定表内时，设备会使路由器不将特定地址存储在路由器的邻居发现（ND）缓存中（例如，通过响应清除缓存或忽略以防止状态为创建）。在另一个实施例中，ND请求路由器确保特定地址不被保留在路由器处的ND高速缓存中，以响应于设备指示特定地址不在其绑定表内（例如，明确的清除响应或没有指令存储状态）。

摘要： Methods and apparatus for processing registration requests by a Home Agent supporting Mobile IP are disclosed. A registration request is received from each of a plurality of Mobile Nodes, the registration request specifying a care-of address, which may be allocated by the Foreign Agent. A binding is established between each of the plurality of Mobile Nodes and the associated care-of address, each of the plurality of Mobile Nodes being associated with one another. For instance, the plurality of Mobile Nodes may be statically or dynamically assigned the same Home Address. A tunnel is then created between the Home Agent and the care-of address for each of the plurality of Mobile Nodes, thereby enabling a server request to be distributed by the Home Agent to one of the plurality of Mobile Nodes or to a cluster of Mobile Nodes (e.g., associated with the care-of address) via the associated tunnel. For instance, a server request addressed to the Home Address may be forwarded directly to one of the Mobile Nodes assigned that Home Address. Alternatively, when an address such as the care-of address is associated with multiple Mobile Nodes, the Foreign Agent may perform a second level of dispatching such that the server request is dispatched to one of the Mobile Nodes in the cluster.
