    • Disclosed herein are apparatus, methods and computer program products for using access point availability information in a wireless communications system. In aspects of the method performed at an access point in a wireless communications system, the access point generates a message indicating the level of availability of the access point; and transmits the message. In aspects of the method performed at user equipment in a wireless communications system, the user equipment receives messages from access points in the wireless communications system, the messages containing access point availability information indicating the respective levels of availability of the access points available for selection by the user equipment; and selects an access point in dependence on the access point availability information. In variants, the user equipment may perform additional steps to determine whether a current or contemplated operating mode requires selection of an access point be made in dependence on access point availability information associated with the access point. Only if the current or contemplated operating mode provides a quality of service that is dependent on level of availability of an access point will the access point availability information be consulted when selecting an access point.

    • A method for encapsulation of labeled datagrams over serial communications links, and a method for extracting the datagrams on the receiving end of the link. The encapsulation method includes adding a label and a label error correction to the front of a datagram, the label error correction being derived using the label and adding a cyclic redundancy check at a trailing end of the datagram, the cyclic redundancy check being derived using the datagram. The end of a packet encapsulating the datagram with a label, a label error correction field and a cyclic redundancy check field is identified by analyzing incoming bits for a packet until a pattern of bits is detected that matches a number of previous bits of the packet coded with a predetermined coding formula and identifying the end of the packet based upon the detection of the match and the predetermined coding formula. The end of the current frame may be identified by coding incoming bits according to the cyclic redundancy check polynomial to produce a calculated cyclic redundancy check until the calculated cyclic redundancy check matches the cyclic redundancy check field. In addition, or alternatively, the end of the previous frame may be identified by coding incoming bits according to the label error correction polynomial to produce a calculated label error correction until the label error correction matches the label error correction field.
    • 用于通过串行通信链路封装标记的数据报的方法,以及用于在链路的接收端上提取数据报的方法。 封装方法包括向数据报的前端添加标签和标签纠错,使用标签导出标签错误校正,并在数据报的尾端添加循环冗余校验,循环冗余校验使用 数据报 通过分析用于分组的输入比特来识别包含具有标签的数据报的分组的结束,标签纠错字段和循环冗余校验字段,直到检测到与编码的分组的先前比特数匹配的比特模式 具有预定的编码公式,并且基于匹配的检测和预定编码公式来识别分组的结束。 当前帧的结束可以通过根据循环冗余校验多项式对输入位进行编码来识别,以产生计算的循环冗余校验,直到所计算的循环冗余校验与循环冗余校验字段相匹配。 此外,或者替代地,可以通过根据标签误差校正多项式对输入位进行编码来识别前一帧的结尾,以产生计算的标签误差校正,直到标签误差校正与标签误差校正字段匹配。

    • A method, system, peers and computer programs determine validity of path information corresponding to a transmission path between a monitoring peer and a monitored peer in a data communication network. The monitoring peer monitors unsolicited data received from the monitored peer via the reverse transmission path identified by the path information and further monitors any data sent to the monitored peer using the path information. Validity tests are performed by the monitoring peer for the path information to restore complete confidence in its validity in a way where the rate of testing is proportional to the rate of receiving unsolicited data from the monitored peer and to the rate of sending data to the monitored peer. The monitoring peer invalidates the path information if the validity test fails.
    • 方法,系统,对等体和计算机程序确定对应于数据通信网络中的监视对等体和被监视对等体之间的传输路径的路径信息的有效性。 监视对等体通过由路径信息标识的反向传输路径监视从受监视对等体接收到的未经请求的数据,并使用路径信息进一步监视发送到被监视对等体的任何数据。 监控对等体对路径信息执行有效性测试,以恢复其有效性的完全置信度,其方式是测试速率与接收受监视对等体的非请求数据的速率成比例,并将数据发送到监视的 同行 如果有效性测试失败,则监视对等体将使路径信息无效。
