Patent ID: 8849112

Claim:
A network comprising: a first node; a second node configured to transmit data traffic to the first node; a third node; a fourth node configured to transmit at least some of the data traffic to the first node via the second node; and a fifth node configured to transmit at least some of the data traffic to the first node via the second node, wherein in response to a request for allocating additional bandwidth capacity associated with one or more specified wavelengths to accommodate the data traffic being transmitted from the second node to the first node, an asymmetrical and dynamic routing system (ADRS) is configured with a first means for enabling the allocation of the requested additional bandwidth capacity associated with the one or more specified wavelengths from the second node to the first node; wherein if the allocation of the requested additional bandwidth capacity associated with the one or more specified wavelengths cannot be enabled from the second node to the first node, the ADRS is further configured with a second means for enabling the allocation of the requested additional bandwidth capacity associated with the one or more specified wavelengths from the second node to the third node and then to the first node, wherein the second node is reconfigured to transmit the data traffic to the first node via the third node; wherein if the allocation of the requested additional bandwidth capacity associated with the one or more specified wavelengths cannot be enabled from the second node to the third node and then to the first node, the ADRS is further configured with a third means for: enabling the allocation of at least some of the requested additional bandwidth capacity associated with the one or more specified wavelengths from the fourth node to the third node, wherein the fourth node is reconfigured to transmit at least some of the data traffic to the first node via the third node; enabling the allocation of at least some of the requested additional bandwidth capacity associated with the one or more specified wavelengths from the fifth node to the third, wherein the fifth node is reconfigured to transmit at least some of the data traffic to the first node via the third node; and enabling the allocation of the requested additional bandwidth capacity associated with the one or more specified wavelengths from the third node to the first node.
