摘要： The present invention provides a method, system, and computer program product for splicing proxied web requests with callback for subsequent requests. The method comprises: initiating by a proxy a Transmission Control Protocol (TCP) splice between first and second socket connections in order to service a request; and returning control of the first and second socket connections to the proxy in response to a completion event associated with the TCP splice.

摘要： An apparatus and method for an improved bulk read socket call are provided. With the apparatus and method, a new field, so_rcvlen, is added to the socket structure that identifies the bulk read size requested by the user. The kernel of the prior art recv( ) function is also modified so that it sets the so_rcvlen to the size requested by the user prior to the recv( ) function going to sleep and waiting for the full data size requested by the user. A new flag, SP_MSGWAITALL, is also provided in the socket structure. In the TCP input processing, when data is received for a particular socket, the current setting of the SP_MSGWAITALL is checked. If the SP_MSGWAITALL flag is set, it is determined whether the amount of data stored in the socket receive buffer is less than the value of so_rcvlen. If not, the TCP input processing does not wake up the recv( ) thread. However, for every alternate segment, the TCP input processing sends back an acknowledgment (ACK). In the TCP output processing, when the SP_MSGWAITALL flag is set and the amount of data in the socket receive buffer is less than so_rcvlen, the full window is advertised. Once the TCP input processing determines that there is at least an amount of data in the socket receive buffer equal to the value of so_rcvlen, the TCP input processing will wake up the recv( ) thread and the SP_MSGWAITALL flag is reset.
摘要翻译： 提供了一种改进的大容量读取插座呼叫的装置和方法。 使用设备和方法，将新字段so_rcvlen添加到标识用户请求的批量读取大小的套接字结构中。 现有技术recv（）函数的内核也被修改，以便在recv（）函数进入休眠状态并等待用户请求的完整数据大小之前，将so_rcvlen设置为用户请求的大小。 插座结构中还提供了一个新标志SP_MSGWAITALL。 在TCP输入处理中，当为特定套接字收到数据时，将检查SP_MSGWAITALL的当前设置。 如果设置了SP_MSGWAITALL标志，则确定存储在套接字接收缓冲区中的数据量是否小于so_rcvlen的值。 如果没有，TCP输入处理不会唤醒recv（）线程。 然而，对于每个备用段，TCP输入处理发回确认（ACK）。 在TCP输出处理中，当设置了SP_MSGWAITALL标志并且套接字接收缓冲区中的数据量小于so_rcvlen时，将通告完整窗口。 一旦TCP输入处理确定套接字接收缓冲区中至少有一定数量的数据等于so_rcvlen的值，则TCP输入处理将唤醒recv（）线程，并重置SP_MSGWAITALL标志。

摘要： A method for efficiently determining the path maximum transmission unit (MTU) during a handshake between a source host and a target host across a computer network. During the handshake, each router receives the SYN (synchronization) packet transmitted from the source host, and each router updates the value of the path MTU within the SYN packet when the path MTU value is greater than the MTU of the router. When the SYN packet reaches the target host, the target host also updates the value of the path MTU if the value of the path MTU within the SYN packet is greater than that of the target host. With this sequential checking and updating of the path MTU against their MTUs, the combination of the routers en-route and the target host ensures that the final path MTU is equal to or smaller than the smallest MTU of the various components/networks along the path.

摘要： A method, system, and program provide for efficient send socket call handling by a transport layer. A transport layer of a network protocol stack receives a send socket call for data of a specified length from an application layer. Responsive to detecting that there is insufficient memory for a single memory allocation to a buffer in the transport layer for at least the specified length, the transport layer blocks the send socket call. The transport layer only wakes the send socket call upon detection of sufficient memory for the single memory allocation within the buffer of the transport layer for at least the specified length, wherein waking the send socket call triggers a kernel to perform the single memory allocation in the buffer and to write the data to the single memory allocation in a single pass.

摘要： A system and method of responding to a flood attack on a data processing system is disclosed. The present invention mitigates the affects of SYN attacks with false IP addresses by immediately removing the associated embryonic connection from the system upon receiving notification that the IP address in the original SYN request is false. Immediate removal of the connection request will mitigate the effects of the flood attack by not requiring the system to devote resources to servicing a connection request from a false IP address, which could result in denial of service for legitimate clients. Immediate removal of the connection request will mitigate the effects of the flood attack by not requiring the system to devote resources to servicing a connection request from a false IP address, which could result in denial of service for legitimate clients.

摘要： A method, system, and product are described for alleviating router congestion when the router is processing packets transmitted by computer systems having a congestion notification capability. The router marks packets transmitted between a first computer system and a second computer system when the first and second computer systems have the congestion notification capability. The marking indicates that the router is moderately congested. A marked packet is then received by the first computer system. The router then drops packets transmitted by the first computer system when the packets were transmitted subsequent to the receipt of the marked packet.
