When an IPv4/v6 dual stack terminal communicating via TCP on IPv6 fails to promptly switch over to IPv4 after the ICMPv6 fails due to a soft error, the problem should be resolved at the prior stage server rather than on the complicated terminal. The server at a stage prior to the terminal receives TCP packets from the terminal to find the TCP connection status on the terminal. When the terminal connection status is SYN-SENT or SYN-RECEIVED, and the server receives an unaddressed soft error such as ICMPv6 “Destination Unreachable: no route to destination (ICMP type=1: code 0)” for that terminal, the server rewrites the ICMPv6 contents as a hard error such as “Destination Unreachable: communication with destination administratively prohibited (ICMP type=1: code 1)” and sends it the terminal.
Slotted aloha congestion control
A slotted Aloha communication system is provided according to one embodiment of the invention. The system may include a hub and a plurality of RCSTs. According to one embodiment, congestion control may occur at the RCST based in part on the number of segments received at the hub, the number of retransmission segments received at the hub and the number of successful collision retransmission segments received at the hub. The hub may communicate information regarding received segments. Congestion control may include calculating a transmission probably, performing a skewed probability measure with a probability equal to the transmission probability. If the results of the probability measure is positive the RCST may transmit or retransmit a segment within a first time prior, if the probability measure is negative then the RCST waits a set time period and reperforms the skewed probability measure.
Backoff procedure for post downlink SDMA operation
Certain aspects of the present disclosure relate to a technique for decreasing a probability of post-backoff collisions that occur during uplink transmissions from multiple user stations (STAs) following completion of downlink transmission from an access point to the STAs.
Method and apparatus for processing media stream queues based on control
A control-based method for processing media stream queues includes: a multimedia control entity processes the talk burst request queues corresponding to different media types when the conditions of triggering processing of different talk bursts are satisfied; and the multimedia control entity sends the assigned talk burst to the corresponding multimedia session terminal. The present invention also provides a corresponding apparatus. By processing the media stream queues, the present invention ensures talk bursts of multiple correlated media types to be assigned in a session.
