An optical network, comprising: an access ring coupling a plurality of gateways and operable to transmit optical signals to and from the gateways, the optical signals comprising multiple wavelengths, each wavelength operable to carry traffic; a local ring coupling one or more add/drop nodes, ADNs, and operable to transmit optical signals between the ADNs; and the one or more ADNs operable to add and drop traffic to and from the optical ring in one or more wavelengths; and at least one gateway is operable to: receive broadcast traffic on the access ring, the broadcast traffic transmitted in one or more wavelengths of the optical signals transmitted on the access ring; forward, on the access ring, a first copy of the broadcast traffic received on the access ring; and forward, to the local ring, a second copy of the broadcast traffic received on the access ring; and receive local traffic originating from one or more of the ADNs on the local ring; forward the local traffic to the access ring; receive, from the local ring, the broadcast traffic forwarded to the local ring by the at least one gateway; and terminate the broadcast traffic received from the local ring. an access ring coupling a plurality of gateways and operable to transmit optical signals to and from the gateways, the optical signals comprising multiple wavelengths, each wavelength operable to carry traffic; a local ring coupling one or more add/drop nodes, ADNs, and operable to transmit optical signals between the ADNs; and the one or more ADNs operable to add and drop traffic to and from the optical ring in one or more wavelengths; and at least one gateway is operable to: receive broadcast traffic on the access ring, the broadcast traffic transmitted in one or more wavelengths of the optical signals transmitted on the access ring; forward, on the access ring, a first copy of the broadcast traffic received on the access ring; and forward, to the local ring, a second copy of the broadcast traffic received on the access ring; and receive local traffic originating from one or more of the ADNs on the local ring; forward the local traffic to the access ring; receive, from the local ring, the broadcast traffic forwarded to the local ring by the at least one gateway; and terminate the broadcast traffic received from the local ring. a local ring coupling one or more add/drop nodes, ADNs, and operable to transmit optical signals between the ADNs; and the one or more ADNs operable to add and drop traffic to and from the optical ring in one or more wavelengths; and at least one gateway is operable to: receive broadcast traffic on the access ring, the broadcast traffic transmitted in one or more wavelengths of the optical signals transmitted on the access ring; forward, on the access ring, a first copy of the broadcast traffic received on the access ring; and forward, to the local ring, a second copy of the broadcast traffic received on the access ring; and receive local traffic originating from one or more of the ADNs on the local ring; forward the local traffic to the access ring; receive, from the local ring, the broadcast traffic forwarded to the local ring by the at least one gateway; and terminate the broadcast traffic received from the local ring. receive broadcast traffic on the access ring, the broadcast traffic transmitted in one or more wavelengths of the optical signals transmitted on the access ring; forward, on the access ring, a first copy of the broadcast traffic received on the access ring; and forward, to the local ring, a second copy of the broadcast traffic received on the access ring; and receive local traffic originating from one or more of the ADNs on the local ring; forward the local traffic to the access ring; receive, from the local ring, the broadcast traffic forwarded to the local ring by the at least one gateway; and terminate the broadcast traffic received from the local ring.
