    • A method and a device of service migration in an automatically switched optical network are disclosed in the present invention, and the method includes: when receiving a migration indication message, a migration node sending an cross information checking request to a transmission plane (S101); when receiving a cross information checking success message, the migration node performing a slot resource migration (S102); and the migration node determining whether it is the destination node of the present service migration, if it is determined to be yes, an cross connection migration is performed directly, otherwise, the cross connection migration is performed after the indication signaling, which is sent by a downstream node and carries a cross connection migration scene, is received (S103). The present invention improves the reliability of the migration from PC to SPC, and further ensures the reliability of the migration by a strict state control and state refresh mechanism.
    • 本发明公开了一种自动交换光网络中业务迁移的方法和装置,该方法包括:接收迁移指示消息时,向发送平面发送交叉信息检查请求的移动节点(S101); 当接收到交叉信息检查成功消息时,迁移节点执行时隙资源迁移(S102); 并且迁移节点确定当前服务迁移的目的地节点是否被确定为是,直接执行交叉连接迁移,否则,在指示信令之后执行交叉连接迁移,该指示信令由 接收下游节点并携带交叉连接迁移场景(S103)。 本发明提高了从PC到SPC的迁移的可靠性,并通过严格的状态控制和状态刷新机制进一步保证了迁移的可靠性。

    • Disclosed herein are representative embodiments for performing entropy coding or decoding using a counter-based scheme. In one exemplary embodiment disclosed herein, a first codeword is received from compressed digital media data. The first codeword is decoded into a first digital media data value by referencing a codeword table that associates the first codeword with the first digital media data value and a second codeword with a second digital media data value. A counter for counting occurrences of the first digital media data value is incremented. The value of the first counter is compared with the value of a second counter that counts occurrences of a second digital media data value. If the value of the first counter and the value of the second counter are equal (or greater than or equal), the codeword table is updated to swap codewords between the first and second digital media values.
    • 这里公开了用于使用基于计数器的方案执行熵编码或解码的代表性实施例。 在本文公开的一个示例性实施例中,从压缩数字媒体数据接收第一码字。 通过参考将第一码字与第一数字媒体数据值相关联的码字表和第二数字媒体数据值的第二码字,将第一码字解码为第一数字媒体数据值。 用于计数第一数字媒体数据值的出现的计数器增加。 将第一计数器的值与计数第二数字媒体数据值的出现的第二计数器的值进行比较。 如果第一计数器的值和第二计数器的值相等(或大于或等于),则更新代码字表以交换第一和第二数字媒体值之间的码字。
