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： 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： Responsive to detecting a need for a mobile device to transfer out of a first network, requests are sent from the mobile device to a communication endpoint in mSCTP. The first request is to stop transmissions to a first address of said mobile device. The second request is to add an intermediary address of a mobility support service designated for receiving any communications already in transmission when the first request is sent. The communication link for the mobile device is then transitioned from the current address at the first network to a second address at a second network. The first network and the second network are non-intersecting networks. The mobile device then indicates to the mobility support service that the handover from the first network to the second network is complete. The mobility support service responds to the completion by sending a third request in mSCTP to the communication endpoint to continue communication with the mobile client at the second address.

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： TCP congestion avoidance is implemented upon retransmission of a packet and is reverted back to the original congestion state upon receipt of an early acknowledgement (ACK), indicating reordering of packets, thereby eliminating a needless restriction on TCP bandwidth. Upon receiving an ACK to a retransmitted packet, it is determined if the ACK resulted from receipt of the original reordered packet or the retransmitted packet, based on the arrival time of the ACK at the sender. If the round-trip-time (RTT) for the retransmitted packet is much lower than the average or current calculated RTT for the network link between sender and receiver, then the retransmission occurred as a result of a reordering event, and the congestion window is restored back to its value prior to the retransmission, thereby permitting the network link to continue operating at its original increased throughput.
摘要翻译： TCP拥塞避免在分组重传时实现，并且在接收到指示重新排序分组的早期确认（ACK）时被恢复到原始拥塞状态，从而消除对TCP带宽的不必要的限制。在向重传的分组接收到ACK时，基于ACK在发送方的到达时间确定ACK是否从接收到原始重新排序的分组或重传分组而产生。如果重发分组的往返时间（RTT）远低于发送方和接收方之间的网络链路的平均或当前计算的RTT，则重新发送作为重排序事件的结果，拥塞窗口为在重传之前恢复其值，从而允许网络链路以其原始增加的吞吐量继续运行。
