Abstract
A gateway exchange node according to a first embodiment of the present invention is disclosed. The gateway exchange node includes an exchange area network (XAN) xswitch. The gateway exchange node includes a wide area network (WAN) wavelength switch coupled to the XAN xswitch.
Claims22
A gateway exchange node, comprising:
- an exchange area network (XAN) xswitch;
- and
- a wide area network (WAN) wavelength switch coupled to the XAN xswitch, the xswitch supports service switching at a sub-wavelength granularity for a network element in an XAN.
A network, comprising:
- a first gateway exchange node having an exchange area network (XAN) xswitch and a wide area network (WAN) wavelength switch;
- and
- a network operations center (NOC) coupled to the gateway exchange node, the xswitch supports service switching at a sub-wavelength granularity for a network element in an XAN.
A gateway exchange node, comprising:
- an exchange area network (XAN) xswitch;
- a wide area network (WAN) wavelength switch;
- a digital crossconnect system (DCS);
- a data switch;
- a voice switch;
- and
- an internet protocol (IP) switch router, the xswitch supports service switching at a sub-wavelength granularity for at least one of the DCS, the data switch and the voice switch in an XAN.
