Patent number: 8717873Abstract: Described embodiments provide an IP-aware modem, such as for use in an IP-aware facsimile machine, operable with an IP packet network. The IP-aware modem has voice-band data engine that receives packets from the packet network, converts data in the packets to PCM samples, stores the samples as PCM sample frames in a buffer for further processing by the modem, and determines for each PCM sample frame whether or not during the conversion one or more packets were missing. An equalizer or timing recovery element in the modem adapts using the PCM sample frames and suspends the adaptation for the time period of each PCM sample frame converted without the one or more missing packets. Similarly, searches of the PCM sample frames for certain modem synchronization signals are skipped when, during the search, the searched PCM sample frame was converted without the one or more missing packets.Type: GrantFiled: May 25, 2012Date of Patent: May 6, 2014Assignee: LSI CorporationInventors: Ximing Chen, Herbert B.

When a packet is transferred from the IPv6 network to the IPv4 network, the translator assigns any of previously prepared IPv4 addresses to an IPv6 address stored in a source storing field of the IPv6 packet. The assigned address is stored in a source storing field of an IPv4 packet. A packet translation unit assigns the foregoing IPv6 address to an IPv4 address stored in a destination storing field of the IPv4 packet, when a packet is transferred from the IPv4 network to the IPv6 network, and stores this address in a destination storing field of the IPv6 packet.Type: GrantFiled: May 11, 2011Date of Patent: November 12, 2013Assignee: Hitachi, Ltd.Inventors: Shinichi Hamamoto, Ken Watanabe, Kazuaki Tsuchiya, Naoya Ikeda

In one aspect, a data transmission structure comprises a consolidated poll and one or more frames transmitted in accordance with the consolidated poll. In another aspect, a Time Division Duplexing (TDD) data transmission structure comprises a pilot, a consolidated poll, and zero or more access point to remote station frames in accordance with the consolidated poll. In one aspect, frames are transmitted sequentially with no or substantially reduced interframe spacing. In another aspect, a guard interframe spacing may be introduced between frames transmitted from different sources, or with substantially different power levels. In another aspect, a single preamble is transmitted in association with one or more frames. In another aspect, a block acknowledgement is transmitted subsequent to the transmission of one or more sequential frames.Type: ApplicationFiled: June 18, 2013Publication date: October 31, 2013Inventors: Sanjiv Nanda, Arnaud Meylan, Jay Rodney Walton

Publication number: 20130279519Abstract: A method for message transmission comprises: receiving a forward message sent from an internal network device to an external network; transmitting the forward message after replacing the source address of the forward message with a public network IP address; receiving a reverse message sent from the external network to the internal network device; and transmitting the reverse message after replacing the destination public network IP address of the reverse message, which is sent from the external network to the internal network device, with a private network IP address of the internal network device. With the method, the NAT device can support more users, and thus the number of NAT devices is reduced and synchronization can be achieved between the internal network device and the NAT device when the NAT device aging occurs.Type: ApplicationFiled: May 24, 2013Publication date: October 24, 2013Inventors: Xushan Lu, Qian Zhou, Jun Peng, Ting Zou

Patent number: 8547998Abstract: The present invention relates to tunneling an IPv6 packet through an IPIv4 network. In using a tunneling method upon transmitting an IPv6 packet in an IP network, when destination nodes desired to be communicated are located within the same IPv6 prefix network, IPv6 prefix information is added for the management of a tunnel entry. Hence, tunneling information on terminals located within the same IPv6 prefix network can be managed as one tunnel entry. Accordingly, the time consumed when retrieving a tunnel entry can be reduced.Type: GrantFiled: October 10, 2008Date of Patent: October 1, 2013Assignee: Electronics and Telecommunications Research InstituteInventors: Seong Moon, Sung Back Hong, Ho Yong Ryu, Sun Cheul Kim, Pyung Koo Park, Ho Sun Yoon, Young Soo Shin
