EPON system and method for setting up bandwidth therein
First Claim
1. An Ethernet passive optical network (EPON) system, comprising:
- at least one optical network unit (ONU) for transmitting a registration request message containing information about a set second bandwidth to an optical line termination (OLT) when a discovery gate message according to a multi point control protocol (MPCP) is received;
wherein the OLT registers said at least one ONU therein according to information about a set first bandwidth and the information about the second bandwidth contained in the registration request message received from said at least one ONU.

Abstract
In an Ethernet passive optical network (EPON) system and a method for setting up a bandwidth therein, the EPON system comprises at least one optical network unit (ONU) for transmitting to an optical line termination (OLT) a registration request message containing information about a set second bandwidth when a discovery gate message according to a multi point control protocol (MPCP) is received. The OLT registers the ONU therein according to information about a set first bandwidth and the information about the second bandwidth contained in the registration request message received from the ONU. The EPON system registers only the ONU having an optimum bandwidth in a network environment where the OLT and the ONU have different bandwidths from each other.

8. An EPON system, comprising:
-
an OLT for broadcasting a discovery gate message containing information about a set first bandwidth; and at least one ONU for recognizing the information about the first bandwidth contained in the discovery gate message received from the OLT, for comparing information about a set second bandwidth to the information about the first bandwidth, for transmitting a registration request message when the information about the first bandwidth is identical to the information about the second bandwidth, and for not registering in the OLT when the information about the first bandwidth width is not identical to the information about the second bandwidth. - View Dependent Claims (9, 10, 11)

12. A method for setting up a bandwidth in an EPON system which includes at least one ONU and an OLT, the method comprising the steps of:
-
at said at least one ONU, transmitting to the OLT a registration request message containing information about a second bandwidth set to said at least one ONU when a discovery gate message according to an MPCP is received; at the OLT, comparing the information about the second bandwidth contained in the registration request message to information about a first bandwidth set to the OLT; and at the OLT, registering said at least one ONU therein and transmitting a registration message when the first bandwidth is identical to the second bandwidth. - View Dependent Claims (13, 14, 15, 16)

17. A method for setting up a bandwidth in an EPON system which includes at least one ONU and an OLT, the method comprising the steps of:
-
at the OLT, broadcasting a discovery gate message containing information about a first bandwidth set to the OLT; at said at least one ONU, identifying the information about the first bandwidth from the discovery gate message; and at said at least one ONU, transmitting a registration request message to the OLT when information about a second bandwidth set to said at least one ONU is identical to the information about the first bandwidth. - View Dependent Claims (18, 19)
