PON System Configuration

The PON system configurations include: Authentication Mode.

Local authentication or remote authentication.

Lport binding.

SLA synchronization.

VLAN ID Base.

ONU authentication timeout (for remote authentication).

System MAC Address Table aging time.

PON Configuration Authentication

Local vs. Remote authentication.

Establishes the difference between authenticatingresources with information available at the OLT itself, orthe need to access a remote server that contains extendedinformation on the subscriber and its services.

telnet@hostname(config-t)# show pon-sys

PON system global parameters:

local sla authentication = enabled

local sla sync with radius server = disabled

local logical port strict binding = enabled

Enable/disable SLA synchronization.

pon-sys sla-synchronization {enabled |

Enable/disable Lport binding with ONU MAC address.

pon-sys lport-strict-binding {enabled|disabled}

Set the VLAN ID Base.

pon-sys vlan-id-base {2-750 | 1262-3839}


8/57


PON System ConfigurationLocal Authentication

Local Authentication uses the ONUs MAC address toauthentication its belonging to the network, or no

authentication at all.

ONU Logical Port (Lport) Assignment.

Each individual ONU is assigned to one of the PON port's

64 logical ports (Lports).

When lport-binding is enabled, the OLT system uses a

binding table that sets a mapping relationship between

ONU MAC addresses and individual Lports.

When lport-binding is disabled, the OLT assigns the

ONU the lowest available lport number.


9/579UTStarcom Confidential

PON System ConfigurationLocal Authentication

ONU Registration Process:1. OLT assigns the ONU a Logical Link ID (LLID).

2. Pre-configured lport number is obtained from the binding

table.

3. This lport number is assigned to the ONU.

4. VLAN ID and other attributes are assigned to the ONU.

Upon successful completion of the registration, each

ONU connected to an individual PON port is assigned aunique Lport number.

Dynamic Bandwidth Allocation (DBA)

Dynamic Bandwidth Allocation (DBA) is essential for anefficient GEPON network.

Allows for performance of over-subscription on the PON.

Upstream Traffic. Upstream rate control for traffic from the ONU to the OLT

is set by Dynamic Bandwidth Allocation (DBA).

Downstream Traffic.

DBA Cycle (Upstream)

DBA algorithm is cycle based. A grant cycle is a period of pre-calculated bandwidth

allocation.

Calculation done based on the collected ONU's requests

from the previous cycle and SLA to allocate bandwidth toONUs for the next cycle.

SLA defines the minimum bandwidth, maximum bandwidth

and maximum burst size for each ONU.

ONU Policy Configuration


55/57



Each PON port supports two policy types: Downlink Policy: Controls downstream bandwidth.

p2p-Stream Policy: Control bandwidth between ONUs.

When in p2p-access mode, ONUs can communicate with

other ONUs.

Downstream Policy

Downstream Policy. Priority of downstream

forwarding: They are high-

priority-frames and short-

frames.

Maximum bandwidth: Theconfigurable range is

0..1000Mbps and

0..1000000kbps.

Max-burst-size: When

there is traffic jam, systemwill guarantee that max-

burst-size data will not get

lost.
