摘要： A packet information field format (Fig. 4) is disclosed which facilitates packet buffer memory overflow control. Generation of the information field is such that like bits from samples representing a corresponding communication channel from a plurality of frames are grouped together. In a specific embodiment (Fig. 2), the bits from the communication channel samples are arranged in groups (via 202) including the most significant bits to the least significant bits. The packet header also includes a field which can have an indication therein of whether bits can be dropped from the packet and an indication of whether bits have already been dropped from the packet.

摘要： Buffer memory (1104) overflow control is realized by controlling (via 1102, 1105, 1110, 1111, 1112) the amount of packet data being inputted to the buffer memory (1104) in response to the amount of packet data stored in the buffer memory. Depending on the type of coding being employed and the amount of data stored in the buffer memory, one or more groups of bits are controllably dropped from the packet information field being inputted into the buffer memory (1104).

摘要： Unwanted distortion in signals being reconstructed from packets is substantially eliminated by employing a virtual sequence packet numbering scheme in conjunction with a time stamp value. A virtual sequence number which accompanies the packet identifies (via 1906) the location of the packet in an information spurt. If the packet is the initial packet in the information spurt, the time stamp value is used (via 1907, 1909, 1910, 1911, 1903) to "build out" the delay experienced by the packet to a fixed overall value. Subsequent packets in the information spurt are concatenated to the information spurt. A packet following one or more lost packets is also identified by the packet virual sequence number and is also treated as an initial packet.

摘要： Delay that a packet experiences in a network node is measured by employing a single local time signal in the node, and by separating a time stamp update function into a network node entry time stamp function and a network node exit time stamp function. The node entry time stamp function is to generate (via 208) a packet originate time value referenced to the local time signal value upon the packet entering the node. This packet originate time value is inserted (via 208) into a packet header time stamp field to be transported through the node. The node exit time stamp function is to generate an updated time stamp value (via 1109) from the packet originate time value from the header time stamp field and the local time signal value upon the packet exiting the node. The updated time stamp value is inserted (via 1106,1107) into the packet header time stamp field in place of the packet originate time value.
摘要翻译：通过在节点中采用单个本地时间信号来测量分组在网络节点中经历的延迟，并且通过将时间戳更新功能分离成网络节点入口时间戳功能和网络节点退出时间戳功能来测量。节点进入时间戳功能是在分组进入节点时生成（通过208）参考本地时间信号值的分组发起时间值。该包起始时间值被插入（通过208）到要通过节点传送的包头时间戳字段。节点退出时间戳功能是根据来自报头时间戳字段的分组发起时间值和离开节点的分组的本地时间信号值来生成更新的时间戳值（经由1109）。将更新的时间标记值（通过1106,1107）插入到包头时间戳字段中，而不是分组发起时间值。
