Abstract
A transmission system is provided which multiplexes and transmits synchronous data and asynchronous data, while maintaining the communication quality required of synchronous data and of asynchronous data respectively. A tag having information used to identify the data as synchronous data or as asynchronous data is added to both synchronous data and to asynchronous data. Tags added to each data item are extracted, and based on the information contained in the tag, each data item is identified as synchronous data or as asynchronous data, and synchronous data is transferred to a time-division switch, while asynchronous data is transferred to a packet switch.
Claims7
A transmission system receiving, from a node on a transmission path, multiplexed data in which synchronous data and asynchronous data are multiplexed and unified as either frames of synchronous data or as frames of asynchronous data, comprising:
- a first switch switching synchronous data;
- a second switch switching asynchronous data;
- and
- a distribution control unit extracting tags added to the data, identifying the data as synchronous data or as asynchronous data based on information included in tags to identify whether the data is synchronous data or asynchronous data, transferring synchronous data to said first switch, and transferring asynchronous data to said second switch.
A transmission system receiving from a node on a transmission path multiplexed data in which synchronous data and asynchronous data are multiplexed and unified as frames of the asynchronous data, comprising:
- a packet switch switching asynchronous data;
- and
- a straight-through processing unit extracting tags added to separated data, transmitting first data which is synchronous data and is not addressed to said packet switch to the node of said transmission path, and transferring second data other than said first data to said switch based on information to identify whether the data is synchronous data or asynchronous data and destination information included in tags.
