APPARATUS AND METHODS FOR ENABLING RECOVERY IN OPTICAL NETWORKS |
摘要 |
Apparatus for enabling an M:N recovery scheme in an optical network includes a set of N working DSP-enabled optical transceivers/transponders including at least one working DSP-enabled optical transceiver/transponder that uses a first set of transmission parameters and at least one working DSP-enabled optical transceiver/transponder that uses a second set of transmission parameters which is different from the first set of transmission parameters, and a set of M protection DSP-enabled optical transceivers/transponders operable to protect the set of N working DSP-enabled optical transceivers/transponders and including L protection DSP-enabled optical transceivers/transponders, each having a capability of using a set of adjustable transmission parameters enabling it to protect every one of the N working DSP-enabled optical transceivers/transponders, and, when M>L, M−L protection DSP-enabled optical transceivers/transponders, each having a capability of protecting at least one, but not all, of the N working DSP-enabled optical transceivers/transponders. Related network and methods are also disclosed. |

1. Apparatus for enabling an M:N recovery scheme in an optical network, wherein M and N are positive integers and 1≦M<N, the apparatus comprising:
a set of N working digital signal processing (DSP)-enabled optical transceivers/transponders which comprises at least one working DSP-enabled optical transceiver/transponder that uses a first set of transmission parameters and at least one working DSP-enabled optical transceiver/transponder that uses a second set of transmission parameters which is different from the first set of transmission parameters; and a set of M protection DSP-enabled optical transceivers/transponders operable to protect the set of N working DSP-enabled optical transceivers/transponders and comprising L protection DSP-enabled optical transceivers/transponders, each having a capability of using a set of adjustable transmission parameters enabling it to protect every one of the N working DSP-enabled optical transceivers/transponders, and, when M>L, M−L protection DSP-enabled optical transceivers/transponders, each having a capability of protecting at least one, but not all, of the N working DSP-enabled optical transceivers/transponders, wherein L is a positive integer and 1≦L≦M. |
