Abstract

A system supporting the daisy chaining of remote optical line terminals.

First claim

The invention claimed is:

1. An access network comprising:
(a) a first optical line terminal capable of receiving digital data and in response providing first transmitted optical digital data to a first plurality of optical network terminals, said first optical line terminal capable of receiving first received optical digital data from said first plurality of optical network terminals and in response providing digital data;
(b) a first routing device associated with said first optical line terminal that receives first digital data and provides a first portion of said first digital data of said received digital data of said first optical line terminal that is provided as said first transmitted optical digital data, and provides a second portion of said of said first digital data to a second routing device;
(c) a second optical line terminal capable of receiving digital data and in response providing second transmitted optical digital data to a second plurality of optical network terminals, said second optical line terminal capable of receiving second received optical digital data from said second plurality of optical network terminals and in response providing digital data;
(d) said second routing device associated with said second optical line terminal that receives said second portion of said of said first digital data as second digital data and provides a first portion of said second digital data of said received digital data of said second optical line terminal that is provided as said second transmitted optical digital data, and provides a second portion of said of said second digital data to another device.

2. The access network of claim 1 further comprising each of said first plurality of optical network terminals capable of receiving said first optical digital data from said first optical line terminal from an optical fiber connection and provide optical digital data to said optical fiber connection to said first optical line terminal.

3. The access network of claim 2 further comprising each of said second plurality of optical network terminals capable of receiving said second optical digital data from said second optical line terminal from an optical fiber connection and provide optical digital data to said optical fiber connection to said second optical line terminal.

4. The access network of claim 1 wherein at least one of said first routing device and said first optical line terminal prioritizes data packets based upon a hierarchical relationship of said first optical line terminal and said second optical line terminal.

5. The access network of claim 1 wherein said first routing device prioritizes data packets between said first optical line terminal and said second optical line terminal.

6. The access network of claim 1 wherein at least one of said first routing device and said first optical line terminal prioritizes data packets based upon a service level agreement associated with each of said data packets.

7. The access network of claim 1 wherein at least one of said first routing device and said first optical line terminal prioritizes data packets based upon a highest service level agreement associated with each of said data packets.

8. The access network of claim 7 wherein said prioritization is based upon a committed information rate of said data packets having an associated said highest service level agreement.

9. The access network of claim 7 wherein said prioritization is based upon a reserved portion of bandwidth for said data packets having an associated said highest service level agreement.

10. The access network of claim 1 wherein (1) at least one of said first routing device and said first optical line terminal and (2) at least one of said second routing device and said second optical line terminal, prioritizes data packets based upon a highest service level agreement associated with each of said data packets from (1) at least one of said first plurality of optical network devices and (2) at least one of said second plurality of optical network devices, with the data packets being temporally synchronized with respect to one another in a non-overlapping manner.
