摘要： Methods and apparatus for supporting broadcast traffic in Mobile IP are disclosed. When a Mobile Node registers via a Foreign Agent supporting Mobile IP, the Foreign Agent receives a registration request from a Mobile Node and sends the registration request to a Home Agent. A registration reply received from the Home Agent has a network mask extension including a network mask associated with the home address of the Mobile Node. The Foreign Agent then sends the registration reply to the Mobile Node. Alternatively, the Mobile Node may register via a collocated care-of address, in which case the registration reply is received directly from the Home Agent. Once the Mobile Node has obtained its network mask, it may send packets such as broadcast packets, as well as roam to its Home Agent. Additionally, in accordance with various embodiments, the Foreign Agent duplicates broadcast packets for transmission to Mobile Nodes, rather than receiving the duplicated packets from the Home Agent. In this manner, broadcast traffic in a Mobile IP environment is optimized.
摘要翻译：公开了支持移动IP广播流量的方法和装置。当移动节点通过支持移动IP的外部代理注册时，外部代理从移动节点接收注册请求，并将注册请求发送到归属代理。从归属代理接收到的注册答复具有包括与移动节点的归属地址相关联的网络掩码的网络掩码扩展。然后，外部代理将注册答复发送到移动节点。或者，移动节点可以通过并置的转交地址进行注册，在这种情况下，直接从归属代理接收注册回复。一旦移动节点获得了网络掩码，它可能会发送数据包，如广播数据包，以及漫游到其归属代理。此外，根据各种实施例，外部代理复制用于传输到移动节点的广播分组，而不是从归属代理接收重复分组。以这种方式，移动IP环境中的广播流量被优化。

摘要： Methods and apparatus are disclosed for storing tree data structures among and within multiple memory channels, which may be of particular use with, but not limited to tree bitmap data structures. A subtree (or entire tree) typically includes one or more leaf arrays and multiple tree arrays. One or more leaf arrays are typically stored in a first set of memory channels of N+1 sets of memory channels, the N+1 sets of memory channels including N sets of memory channels plus the first set of memory channels. Each of N contiguous levels of the multiple tree arrays are stored in a different one of said N sets of memory channels, wherein each of the multiple tree arrays at a same level of said N contiguous levels is stored in the same memory channel set of said N sets of memory channels. A memory channel for storing a particular level is typically assigned based on one or more current occupancy levels of the memory channels.

摘要： A technique is described for facilitating block level access operations to be performed at a remote volume via a wide area network (WAN). The block level access operations may be initiated by at least one host which is a member of a local area network (LAN). The LAN includes a block cache mechanism configured or designed to cache block data in accordance with a block level protocol. A block level access request is received from a host on the LAN. In response to the block level access request, a portion of block data may be cached in the block cache mechanism using a block level protocol. In at least one implementation, portions of block data in the block cache mechanism may be identified as “dirty” data which has not yet been stored in the remote volume. Block level write operations may be performed over the WAN to cause the identified dirty data in the block cache mechanism to be stored at the remote volume.
摘要翻译：描述了一种用于促进通过广域网（WAN）在远程卷执行块级访问操作的技术。块级访问操作可以由至少一个作为局域网（LAN）成员的主机发起。 LAN包括被配置或设计为根据块级协议来缓存块数据的块高速缓存机制。从LAN上的主机接收到块级访问请求。响应于块级访问请求，块数据的一部分可以使用块级协议来缓存在块高速缓存机制中。在至少一个实现中，块高速缓存机构中的块数据的部分可以被识别为尚未存储在远程卷中的“脏”数据。可以通过WAN执行块级写入操作，以使块缓存机制中识别的脏数据存储在远程卷中。

摘要： Disclosed are methods, computer program products, apparatus, and systems for sending and receiving uniform serial bus (“USB”) messages between a host computer and a USB device over a data network, using a USB server in communication with the data network and the host computer, and a USB client in communication with the data network and the USB device. An association is established between the USB server and the USB client. The USB server receives a first USB message from the host computer. The first USB message is translated to a format suitable for sending over the data network, and sent as a first network message from the USB server to the USB client over the data network. The USB server receives a second network message from the USB client over the data network, and translates the second network message to a USB format. At the USB server, the translated second network message is provided as a second USB message for the host computer.

摘要： Methods and apparatus for enabling a Mobile Node supporting mobile IP to roam without an assigned IP address and receive lookups indicating that a Corresponding Node wants to send information to the Mobile Node are disclosed. A name lookup may be sent from a Corresponding Node to a Home Agent that has previously registered the Mobile Node. The name lookup may be sent through an intermediate device, including a Domain Name Server, such that the intermediate device contacts the Home Agent. During the name lookup process, an IP address is allocated to the Mobile Node and a data path is established between the Home Agent and the Mobile Node via a Foreign Agent. When the lookup is completed successfully, the Home Agent sends the IP address allocated to the Mobile Node in the name lookup process to the device requesting the lookup. The IP address of the Mobile Node may then be used by the Corresponding Node to “push” information to the Mobile Node.
摘要翻译：公开了一种使支持移动IP的移动节点在没有分配的IP地址的情况下漫游并且接收指示相应节点想要向移动节点发送信息的查找的方法和装置。名称查找可以从对应节点发送到先前注册了移动节点的归属代理。名称查找可以通过包括域名服务器在内的中间设备发送，使得中间设备联系归属代理。在名称查找过程中，将IP地址分配给移动节点，并且通过外部代理在归属代理和移动节点之间建立数据路径。当查询成功完成时，归属代理将名称查找过程中分配给移动节点的IP地址发送到请求查找的设备。移动节点的IP地址然后可以被对应节点用来将信息“推送”到移动节点。

摘要： Methods and devices are provided for establishing a VPN tunnel for a user whose IP address is not known in advance (a “road warrior”). The road warrior first initiates a secure authentication session with a security gateway. In some such implementations, the road warrior provides a username/password pair that the security gateway compares to a database of usernames that have been authorized to initiate a VPN tunnel. After authenticating the road warrior, the security gateway then determines the IP address of the road warrior, then makes a correlation between the IP address, user, and a shared secret allocated to the road warrior. If the road warrior uses the proper shared secret in connection with a request to establish a VPN tunnel, the security gateway will establish the VPN tunnel.

摘要： Methods and devices are provided for implementing flow control coordination in a gateway between a TCP/IP network and a second network. The second network may be any type of network, including another TCP/IP network. In some implementations, the throughput of the TCP/IP network is controlled by modifying the round trip time observed by a TCP connection. In other implementations, the throughput of the TCP/IP network is controlled by modifying the size of the TCP window.

摘要： Methods and devices are provided for implementing a dual mode firewall. Some implementations provide a firewall in a network device that acts as a bridge for layer 2 traffic and acts as a router for layer 3 traffic. In some implementations, a determination of whether to act as a bridge or a router for a packet is based on the configuration of the interface handling the packet. In some implementations, the network device inspects a destination of each packet to determine whether to act as a bridge or a router for that packet. The firewall screens both the layer 2 and the layer 3 traffic according to policies implemented in the firewall.
