摘要： A method, apparatus, and computer instructions for reactivating an existing connection to a remote data processing system. A data packet is created using a previously acknowledged sequence number for the connection. The sequence number is used to uniquely number data bytes sent in a connection, such as a TCP connection. With this sequence number, devices and components, such as routers and fire walls will forward the packet to the destination. A special data sequence, such as a MAC address of the remote data processing system repeated a selected number of times, is placed in the data packet. This special data sequence causes the remote data processing system to wake up from a sleep mode when received by the remote data processing system. The data packet is sent to the remote data processing system using the existing connection. The use of a subnet directed broadcast is avoided. Thus, problems associated with routing wake up packets are avoided.

摘要： Administering acknowledgment messages (‘ACKs’) in the Transmission Control Protocol (“TCP”) that include establishing a TCP connection between a sender and a receiver, receiving by the receiver one or more TCP messages from the sender, and transmitting an ACK from the receiver to the sender only when necessary. Administering ACKs in TCP according to embodiments of the present invention may include measuring by the sender a round trip time for transmission of TCP messages between the sender and the receiver and transmitting to the receiver a data-bearing TCP message once per round trip time. Establishing a TCP connection between a sender and a receiver may include measuring by the receiver a round trip time for transmission of TCP messages between the receiver and the sender. Transmitting an ACK only when necessary may include transmitting an ACK when no message from the sender arrives at the receiver for two round trip times.

摘要： A system, apparatus and method of improving network data traffic between interconnected high-speed switches are provided. As is well known, when a packet of data is longer than a path maximum transmission unit (PMTU), the packet will be fragmented. In the case of the invention, the packet is fragmented by a transmitting router connected to a high-speed switch. When a receiving router, which is also connected to an high-speed switch, begins to receive the fragments, it will check to see whether its sub-network may handle data of a substantially longer length than the length of the fragments. If so, the receiving router will collect the fragments, reassemble them into the original packet and transmit the reassembled packet to its destination.

摘要： A method, system, and program for redirecting client connection requests among sockets providing a same service are provided. An application requests multiple sockets from a kernel. In addition, the application generates a socket call option to bind the sockets to a particular port number and passes a list of the sockets to the kernel, where the list indicates that the sockets will all provide access to server systems providing the same service. In response, the kernel sets up the sockets, bound to the same port, and set to reference one another. Then, when a connection request is received for a first socket in the list with a queue that is full, the kernel redirects the connection request to a second socket in the list with available queue space. Thus, rather than drop the connection request from the first socket when it lacks available queue space, the connection request is redirected to another socket providing access to the same service.

摘要翻译： 提供了一种用于在提供相同服务的套接字之间重定向客户端连接请求的方法，系统和程序。 应用程序从内核请求多个套接字。 此外，应用程序还会生成套接字调用选项，将套接字绑定到特定端口号，并将套接字列表传递给内核，其中列表指示套接字将提供对提供相同服务的服务器系统的访问。 作为响应，内核设置了绑定到相同端口的套​​接字，并设置为引用彼此。 然后，当对于队列已满的列表中的第一个套接字接收到连接请求时，内核将连接请求重定向到列表中具有可用队列空间的第二个套接字。 因此，当连接请求缺少可用的队列空间时，而不是从第一个套接字中删除连接请求，则将连接请求重定向到提供对同一服务的访问的另一个套接字。

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： 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.
