US 2017/0244570 A1 · MULTICAST SWITCHING SYSTEM

Abstract

As compared to the conventional method, a non-blocking multicast switching system is provided in which the number of switches to be operated can be reduced and the path switching can be quick. A multicast switching system with an input stage, a middle stage, and an output stage, including a plurality of input switch elements of receiving/transmitting streams from input sources/to the middle stage, a plurality of middle switch elements of receiving/transmitting streams from the input switch elements/to the output stage, the plurality of middle switch elements being grouped into a plurality of groups and a plurality of output switch elements of receiving/outputting streams from the middle switch elements/to output destinations, wherein the input switch elements transmit the streams to each of the plurality of groups.

Dependent claims

A multicast switching system with an input stage, a middle stage, and an output stage, comprising:

a plurality of input switch elements which are provided at the input stage, configured to receive streams from input sources, and transmit the received streams to the middle stage;
a plurality of middle switch elements which are provided at the middle stage, configured to receive the streams transmitted from the plurality of input switch elements, and transmit the received streams to the output stage, the plurality of middle switch elements being grouped into a plurality of groups;
and
a plurality of output switch elements which are provided at the output stage, configured to receive streams transmitted from one or more of the plurality of middle switch elements, and output the received streams to output destinations,
wherein the plurality of input switch elements are configured to transmit the received streams to each of the plurality of groups.

A bidirectional-transmission multicast switching system with an input-output stage and a middle stage, comprising:

a plurality of input-output switch elements which are provided at the input-output stage, configured to receive streams from input sources, and transmit the received streams to the middle stage;
and
a plurality of middle switch elements which are provided at the middle stage, configured to receive the streams transmitted from the plurality of input-output switch elements, and transmit the received streams to the input-output stage, the plurality of middle switch elements being grouped into a plurality of groups,
wherein the plurality of input-output switch elements are configured to receive streams transmitted from one or more of the plurality of middle switch elements, and output the received streams to output destinations, and
the plurality of input-output switch elements are configured to transmit the streams received from the input sources to each of the plurality of groups.
