Methods and systems for time sensitive networks
A packet based switched multimedia network which consolidates networking of high throughput, time sensitive data, and control streams, with Ethernet data networking over home span. The multimedia network may support in parallel, over the same home span cabling infrastructure, high quality networking including time sensitive data streams, such as HDMI, USB, and Ethernet, transparent network attachment for legacy devices, multi stream, and low power modes.
1. A method for translating and conveying control channels between first and second legacy end-devices supporting first and second different legacy control formats respectively, the method comprising:
discovering, by a network, the first and second legacy end-devices supporting the first and second legacy control formats, respectively;
discovering, by the network, a third legacy end-device;
wherein the network is not a mere point-to-point connection, and supports at least two different connectivity combinations between the first, second, and third legacy end-devices;
spoofing, by the network, a first network view for the first legacy end-device to enable the first legacy end-device to communicate with both the second and third legacy end-devices over the network using the first legacy control format;
spoofing, by the network, a second network view for the second legacy end-device to enable the second legacy end-device to communicate with both the first and third legacy end-devices over the network using the second legacy control format; and
after receiving an indication that the first legacy end-device selected the second legacy end-device, converting a first legacy message generated by the first legacy end-device to a network message, conveying the network message over the network, and converting the network message to a second legacy message before forwarding it to the second legacy end-device; wherein the first legacy message, the second legacy message and the network message are different.
2. The method of claim 1 , further comprising waiting for an indication of the first legacy end-device to select the second legacy end-device.
3. The method of claim 2 , further comprising generating a session over the network between the first and second legacy end-devices.
4. The method of claim 3 , wherein the session includes resource allocation.
5. The method of claim 4 , wherein the resource allocation includes guaranteed bandwidth.
6. The method of claim 4 , wherein the resource allocation sets a maximum number of interfering streams.
7. The method of claim 1 , wherein the network message is a Multimedia Network Control and Management Protocol (HD-CMP) messages.
8. A method for translating and conveying control channels between at least three legacy end-devices supporting at least two different legacy control formats, the method comprising:
discovering by a network, first, second, and third legacy end-devices coupled to the network, wherein the network is not a mere point-to-point connection and supports at least two different connectivity combinations between the first, second, and third legacy end-devices coupled to the network;
spoofing, by the network, network views for the first, second, and third legacy end-devices to enable the first, second, and third legacy end-devices to communicate with each other over the network using their legacy control formats; wherein the legacy control formats of the first and second legacy end-devices are different;
receiving a selection indication between the first and second legacy end-devices coupled to the network;
determining that the network is able to guarantee required resources needed to connect between the first and second legacy end-devices;
generating a session over the network between the first and second legacy end-devices;
allocating the resources needed for the session; and
after receiving an indication that the first legacy end-device selected the second legacy end-device, converting a first legacy message generated by the first legacy end-device to a network message, conveying the network message over the network, and converting the network message to a second legacy message before forwarding it to the second legacy end-device; wherein the first legacy message, the second legacy message and the network message are different.
9. The method of claim 8 , further comprising transmitting the selection indication from the first legacy end-device to the second legacy end-device, over the network, by converting the legacy format of the first legacy end-device to the format supported by the network, and then converting the network supported format to the format supported by the second legacy end-device.
10. The method of claim 8 , wherein the network message is a Multimedia Network Control and Management Protocol (HD-CMP) messages.
11. A network comprising:
a network adaptor configured to utilize first and second different legacy control formats to communicate with first and second legacy end-devices, respectively, in order to discover the first and second legacy end-devices;
the network adaptor further communicates with a third legacy end-device, utilizing a legacy control format appropriate to the third legacy end-device, in order to discover the third legacy end-device;
wherein the network is not a mere point-to-point connection, and supports at least two different connectivity combinations between the first, second, and third legacy end-devices;
a first spoofing adaptor configured to utilize a first network view for the first legacy end-device in order to enable the first legacy end-device to communicate with both the second and third legacy end-devices over the network using the first legacy control format; wherein the first network view comprises addresses appropriate to the first legacy control format;
a second spoofing adaptor configured to utilize a second network view for the second legacy end-device in order to enable the second legacy end-device to communicate with both the first and third legacy end-devices over the network using the second legacy control format; wherein the second network view comprises addresses appropriate to the second legacy control format; and
after receiving an indication that the first legacy end-device selected the second legacy end-device, converting a first legacy message generated by the first legacy end-device to a network message, conveying the network message over the network, and converting the network message to a second legacy message before forwarding it to the second legacy end-device; wherein the first legacy message, the second legacy message and the network message are different.
12. The network of claim 11 , wherein the network message is a Multimedia Network Control and Management Protocol (HD-CMP) message.
13. The network of claim 12 , wherein after receiving the indication the network generates a session over the network between the first and second legacy end-devices.
14. The network of claim 13 , wherein the network sets a maximum number of interfering streams for the session between the first legacy end-device and the second legacy end-device.
15. The network of claim 13 , wherein the network sets a guarantee bandwidth for the session between the first legacy end-device and the second legacy end-device.
16. The network of claim 15 , wherein the network utilizes the guaranteed bandwidth in order to set a maximum number of interfering streams.
