摘要： System and method for maintenance and examination of timers for a computer system having connections in a networking system. Timer values in a connection table each indicate a timeout for a timer for a connection, where each connection has multiple timers, and one of the timer values is written to a global timer array for each connection such that the global timer array can be scanned to determine when timeouts occur for active connections. Sparse restart of a timer includes restarting the timer if data is communicated with a connected computer before the timeout occurs and after a predetermined time interval after timer start, and not restarting the timer if data is communicated before the timeout occurs and within the predetermined interval after timer start.

摘要： A method, computer program product and system for processing TCP/IP packets. A TCP protocol stack may store a payload of a received TCP/IP packet in a data fragment list. The TCP protocol stack may further read the header of the received packet to extract a value used to index into a table storing a list of transport control blocks (TCBs). The TCP protocol stack may further perform a lock and a read operation on the TCB indexed in the table. The TCP protocol stack may further transmit the payload to the TCP application without requiring the application to perform a lock, read, write or unlock operation on the indexed TCB since the TCP protocol stack and the TCP application are operating on the same thread. By the TCP application foregoing the lock, read, write and unlock operations on the TCB, there is a reduction in the number of memory accesses.

摘要： A method and system for authenticating a mobile network node in a Wireless Local Area Network (WLAN), wherein the mobile network node requests access to the WLAN at an access point. Within a closed first network region, before authentication all network protocol layers up to the Layer 3 protocol layer are set up. An authenticator based on Extensible Authentication Protocol (EAP) is generated on the Web server as a captive portal and the Layer 3 protocol layer between the authenticator and the mobile network node including an EAP peer is extended bidirectionally by a defined bit sequence. In case of an access request, the Web server transmits an authentication stimulus to the mobile node by encoding an EAP message request and transmitting it in the Layer 3 protocol layer by the defined bit sequence. The mobile node decodes the EAP message request and transmits, in the Layer 3 protocol layer, by the defined bit sequence, an encoded EAP response message to the authenticator, the EAP response message includes authentication data of the mobile network node. The Web server decodes the EAP response message from the bit sequence, transmits it to an AAA server including an EAP server by an authentication inquiry. On the basis of an authentication response by the AAA Server, access is enabled to a second network region for use by the mobile network node by a Network Access Server.

摘要： Described is a method for managing flow of protocol information in a node of a hierarchical network in which the protocol information is communicated between network nodes in topology state elements. The method comprises checking topology state elements generated by the node to identify protocol information encapsulated therein, and selectively allowing transmittal of the topology state elements from the node to lower levels of the network based on the protocol information identified.

摘要： Described is a method and system for processing data packets of a data stream in a communication system. The data packets are processed depending on a feature of the header of a data packet in a faster path or in a slower path. To avoid a disorder by the different processing paths, the fast processed data packets are stored in a memory. The stored fast processed data packets are output after all slowly processed data packets which before the processing were in order before the fast data packets have been put to the output. In this way, the processed data packets are in the same order as prior to the processing.
