Title:
METHOD AND SYSTEM FOR BANDWIDTH ALLOCATION IN PASSIVE OPTICAL NETWORK
Document Type and Number:
WIPO Patent Application WO/2010/048792
Kind Code:
A1
Abstract:
The present invention provides a method and a system for bandwidth allocation in passive optical network (PON), the method includes: when Optical Line Terminal (OLT) allocates upstream bandwidth for Optical Network Unit (ONU), the flag of allocation type is carried in upstream bandwidth allocation information to indicate the type of bandwidth allocated for ONU; ONU receives the bandwidth allocation information, and then maintains and uses the corresponding upstream bandwidth according to the flag of allocation type. For bandwidth allocated in fixed bandwidth allocation type, the present invention enables that a new bandwidth allocation will be processed only when previously allocated bandwidth of related T-CONT needs to be changed, alleviating the load of OLT for allocating the upstream bandwidth, reducing the occupation for downstream bandwidth.
