Abstract: In a Computer Telephony Integration environment, to reduce the risk of inadvertent or fraudulent registration of the association of a user's computer terminal with the wrong telephone, i.e. one other than the telephone adjacent to the computer terminal or the user's mobile telephone, a host computer instructs the user via a screen display to call a particular extension of a CTI-enabled communications switching system. When a call to that extension is detected, the communications switching system reports this to the host computer which stores a set of at least one characteristics of the calling telephone terminal including a unique terminal identifier. The user is then provided with a second telephone number via the computer terminal associated with the telephone terminal which was detected as having dialled the first number.

Abstract: Multicast information contained in a request from an IP TV set top box for video content to an IGMP manager is passed to an SA processor to perform a lookup of an SA table. A result of the lookup is the frequency of the downstream legacy channel over which the requested content is being delivered from an edge QAM device. The SA processor instructs a legacy QAM tuner to tune the determined frequency. The IGMP manager selects packets corresponding to the request content based on a program identifier that is associated with the multicast address in the SA table. As selected packets are received by the IGMP manager, multicast address information is placed into them, and they are passed on from the manager to the IP TV set top box. The IP TV set top box receives the requested content packets based on the multicast address.

Abstract: A re-sequencing system offloads the cycle intensive task of re-sequencing TCP packets from host memory using a partial offload engine to re-sequence out-of-sequence data packets. However, as opposed to re-ordering the actual data packets, no actual data copy is needed. Instead, packet descriptors associated with each data packet are generated, and it is the packet descriptors that are re-sequenced. The data packets themselves are temporarily stored in packet buffers while the packet descriptors are sorted into sequence. The re-sequencing system preferably re-sequences a data stream of TCP data packets received from an ethernet network. The re-sequencing system is implemented within a computing device, preferably a personal computer or a server.

Abstract: There are disclosed a method and apparatus for reordering sequenced data packets. An expiration time is calculated for each received data packet.

The next data packet is output if available. If the next data packet is not available, a true expiration time is determined for the unavailable next data packet. If the unavailable next data packet fails to arrive before a current time is greater than the expiration time of the unavailable data packet, the unavailable next data packet is considered lost.
