摘要： Methods, systems, and products are provided for tunneling IPv6 packets. Embodiments include receiving, by an origin IPv6 border router from an origin IPv6 host, an IPv6 packet having an IPv6 destination address; receiving, by an origin IPv6 border router from an origin IPv6 host, an IPv4 address for a destination IPv6 border router retrieved from a data structure associating IPv6 destination addresses with IPv4 addresses for destination IPv6 border routers; encapsulating, by the origin IPv6 border router, the IPv6 packet in an IPv4 packet; and sending the encapsulated packet to a destination IPv6 border router at the IPv4 address. In many embodiments, encapsulating, by the origin IPv6 border router, the IPv6 packet in an IPv4 packet is carried out by adding an IPv4 header to the IPv6 packet.

摘要： A receiving host in a TCP/IP network sends an acknowledgment indicating a received data packet is corrupt. The sending host will begin transmitting with a new field set in the IP header called a check-TCP-checksum bit, thereby requesting that all routers in the TCP/IP network perform a checksum on the entire received packet. Routers in the TCP/IP network will perform a complete checksum on an entire packet with the check-TCP-checksum bit set, and not just on the IP header. The routers continuously monitor the ratio of corrupt packets received on a particular port that fail the entire packet checksum to the total number of packets received on that port. If the ratio of corrupt-to-received packets exceeds a corruption threshold, the router assumes that the associated link is causing data corruption and issues a routing update indicating that the link is bad and should be avoided. Once the retransmission rate between the sender and receiver drops below a threshold level, the bad link has been detected and avoided within the TCP/IP network and the check-TCP-checksum option in the IP header is no longer set in data packets transmitted to the receiver host.
摘要翻译： TCP / IP网络中的接收主机发送指示接收到的数据包已损坏的确认。发送主机将开始使用称为检查TCP校验和位的IP报头中设置的新字段进行发送，从而请求TCP / IP网络中的所有路由器对整个接收到的数据包执行校验和。 TCP / IP网络中的路由器将对整个数据包执行完整的校验和，同时检查TCP-checksum位，而不仅仅是在IP报头上。路由器连续监视在特定端口上接收的损坏数据包的总数与在该端口上接收的数据包的总数之间的比例。如果损坏的数据包的比例超过了破坏阈值，则路由器假设相关联的链路导致数据损坏，并发出路由更新，指示链路不良，应该避免。一旦发送方和接收方之间的重传速率下降到阈值以下，就会在TCP / IP网络内检测并避免不良链路，并且IP报头中的check-TCP-checksum选项不再被设置在发送到接收主机。

摘要： A method for enabling multi-tuple TCP sockets within a computer network is disclosed. All possible connection paths between a first computer and a second computer are initially determined. Then, tuple information of all the possible connection paths are stored in a respective socket of the first and second computers as multi-tuple information. Next, one of the possible connection paths is designated as a preferred path and the remaining possible connection paths are designated as alternate paths. Finally, data packets are transmitted via the preferred path after a TCP connection has been established between the first and second computers on the preferred path.

摘要： In a method comprising an embodiment of the invention, an original application initially binds to a port, and selects or designates a confidential key, which usefully may be a conventional cookie. The invention also sets a socket option, referred to by way of example, as SO_SECURE_REUSEPORT. The confidential key, together with the port number, is then registered with the operating system of a host associated with the port. In order for another application to subsequently bind to the port, such application must provide the operating system with a key that is identical to the confidential key. In one useful embodiment of the invention, a first application binds a socket to a particular port associated with the host. A specified key is registered with the operating system, and a second application is allowed to bind to the particular port only if the second application can furnish the operating system with a key that matches the specified key.
摘要翻译：在包括本发明的实施例的方法中，原始应用程序最初绑定到端口，并且选择或指定可有可能是传统cookie的机密密钥。本发明还将作为示例引用的套接字选项设置为SO_SECURE_REUSEPORT。然后将密钥与端口号一起注册到与端口相关联的主机的操作系统。为了使另一个应用程序随后绑定到端口，这样的应用程序必须向操作系统提供与机密密钥相同的密钥。在本发明的一个有用的实施例中，第一应用将套接字绑定到与主机相关联的特定端口。指定的密钥被注册到操作系统，并且仅当第二应用可以向操作系统提供与指定密钥匹配的密钥时，允许第二应用绑定到特定端口。

摘要： A method and system for providing subgroup conversation during a teleconference enables side conversations during a virtual meeting. A passcode is used by parties to join the subgroup conversation, so that privacy of the subgroup is maintained. Alternatively, an administrator may set up subgroups and either join or invite members, who may toggle between the main teleconference and a subgroup teleconference using a standardized user input. The system may be implemented in any telephone network and across telephone networks such as public switched telephone networks (PSTNs), wireless networks, voice over Internet protocol networks and/or private branch exchanges (PBXs).

摘要： A system and method for forwarding URL's to one or more recipients using a Wireless Access Protocol (WAP) network is provided. A mobile user views web pages on his WAP enabled wireless device, such as a mobile telephone or PDA. When the mobile user locates a web page that he prefers to view later or wants to send to another user, the mobile user invokes redirect software which composes a redirect request that includes one or more redirect entries. Each redirect entry corresponds to a redirect address and a URL. When the user finishes with selecting one or more redirect addresses, the mobile device sends the redirect request to a WAP gateway. The WAP gateway receives the redirect requests and forwards the redirect entries to the corresponding redirect addresses over a computer network, such as the Internet.

摘要： DHCP lease negotiation is performed in advance of a specified time when the IP address is needed. The client sends a DHCP discover message with an advance lease option indicating a future time when an IP address is needed. The DHCP server reserves an IP address available at the requested time for the requesting client and sends a DHCP acknowledgment of the reservation. Thereafter, the client sends a DHCP discover message requesting the reserved IP address, and the DHCP server assigns it to the client at the scheduled time.

摘要： The present invention provides a method and apparatus for multicast tunneling for mobile devices. The method comprises receiving a multicast packet directed to a plurality of mobile nodes, the mobile nodes being associated with a home subnet and identifying if any of the plurality of the mobile nodes are coupled to a subnet other than the home subnet, wherein each of the identified mobile nodes has an associated transmission path through which that mobile node can be reached. The method further provides that in response to determining that at least some of the mobile nodes are coupled to the subnet other than the home subnet, determining which of the identified mobile nodes has a common next hop in their associated transmission path and generating a packet including at least a portion of the multicast packet and including in the packet a list of mobile nodes that have the common next hop. The method further provides for transmitting the generated packet to the common next hop.

摘要： A method for addressing a workload partition is provided in the illustrative embodiments. A packet of data directed to the WPAR and including a combined address is received at a software stack. A determination is made whether the combined address includes an identifier that is reserved. If the identifier is not reserved, the identifier is used to identify the WPAR in the data processing system and the packet is sent to the WPAR. The software stack is an application configured to enable data communication using a protocol of the packet, and is modified to detect, recognize, and process the combined address for routing the packet to the WPAR. The combined address may be logically formed using an identifier associated with the data processing system and an identifier associated with the WPAR, which may be located in different portions of the packet.
