Abstract
An interface for an optical node with a plurality of input ports and output ports in SONET/SDH optical network connected to a plurality of virtual concatenation channels has a plurality of input ports for taking Ethernet signals as inputs, and a plurality of output ports for selectively outputting Ethernet frames in the Ethernet signals to the virtual concatenation channels. A method classifies the Ethernet input pipes in a SONET/SDH network with a plurality of virtual concatenation channels, and allocates the classified packets onto the virtual concatenation channels.
Claims27
An interface for an optical node in a SONET/SDH optical network with a plurality of virtual concatenation channels, comprising:
- a plurality of input ports for accepting Ethernet signals and a plurality of output ports for selectively outputting Ethernet frames in said Ethernet signals to said virtual concatenation channels, wherein said virtual concatenation channels are connected to said output ports.
A method for processing a plurality of Ethernet input signals from an optical node in a SONET/SDH network having a plurality of virtual concatenation channels, comprising:
- classifying Ethernet frames in said Ethernet input signals;
- and
- allocating said classified Ethernet frames to said virtual concatenation channels.
A SONET/SDH optical network with a plurality of nodes interconnected to a plurality of Ethernet router/switches, comprising:
- a first of the nodes for receiving a plurality of Ethernet signals from said Ethernet router/switches as inputs;
- means for classifying and mapping Ethernet frames from said Ethernet signals to a plurality of virtual concatenation channels for transmitting on said network;
- a second of the nodes interconnecting with said first node via said virtual concatenation channels for receiving said transmitted signals on said virtual concatenation channels;
- means for processing and mapping said transmitted signals into Ethernet signals for outputting to said Ethernet router/switches.
