Hitless service in a variable rate optical transponder

摘要

Methods and systems for variable rate control include determining a new communications rate in response to measured data traffic patterns. A receive change message is transmitted to a receiver that triggers the receiver to wait for an end of transmission (EoT) message and to set a new communications rate. A transmit change message is transmitted to a transmitter that triggers the transmitter to send the EoT message to the receiver, to set the new communications rate, and to send a start of transmission (SoT) message to the receiver before resuming data communications.

主权项

1. A receiver, comprising:
a variable rate transponder that provides data communications at a configurable rate; and a hitless service provisioning (HSP) module configured to set a new communications rate of the variable rate transponder in response to the receipt of an end of transmission (EoT) message and to trigger a resumption of communications at the new rate in response to the receipt of a start of transmission (SoT) message, wherein the transponder receives a training pattern prior to receipt of the SoT message to train for a connection resumption; wherein the HSP module is further configured to set the new communications rate based on received instructions from a centralized controller and receive the instructions prior to reception of the EoT message.
