Abstract
A signal processing method and device of multi-protocol switching network are provided, which belong to the field of network communication. The method enables time division multiplexed (TDM) frames to be transmitted in a form of sub cell information through de-interleaving and slicing processes of the TDM frames. The method and device can switch TDM frames and packets uniformly with a flexible processing manner and low cost, so as to better support the network to evolve from TDM to All IP.
Claims11
A method for signal processing on a multi-protocol switching network, comprising:
- uniformly slicing time division multiplexed (TDM) frames and packet data into data using a sub cell as a base unit, wherein the TDM frames and packet data use STM-1 as a unit;
- loading egress port information of a switch matrix of the multi-protocol switching network into a header of the sub cell;
- switching the data using the sub cell as the base unit;
- reverse slicing the switched data into TDM frames and packet data;
- and
- sending the TDM frames and packet data.
A signal processing device of a multi-protocol switching network, comprising:
- a slicing unit, configured to uniformly slice TDM frames and packet data into data using a sub cell as a base unit, wherein the TDM frames and the packet data use STM-1 as a unit;
- a loading unit, configured to load egress port information of a switch matrix of the multi-protocol switching network into a header of the sub cell;
- a switching unit, configured to switch the data using the sub cell as the base unit;
- and
- a reverse slicing unit, configured to reverse slice the switched data into TDM frames and packet data and then send the TDM frames and the packet data.
