Patent ID: 8189471

Claim:
A method for mapping a service flow to a service transmission channel, comprising: A. configuring an Optical Network Terminal (ONT) with message characteristic configuration parameters; B. mapping the service flow to a specified service transmission channel when it isdetermined that the service flow matches the configured message characteristic configuration parameters after the service flow is received by the ONT; wherein the step of mapping the service flow to the specified service transmission channel comprises: mapping first data from a first user or user network interface to a first queue of a first transmission container (T-CONT) via a first Giga-bit Passive Optical Network Encapsulation Method PORT (GEM PORT); mapping a first control message from the first user or user network interface to a second queue of the first T-CONT via a second GEM PORT, wherein the second queue has a higher priority than the first queue and has no data being mapped thereto, wherein the first control message includes at least one type of an Internet Group Management Protocol (IGMP) control message, a PPP protocol on Ethernet (PPPoE) control message, a Dynamic Host Configuration Protocol (DHCP) control message and a Session Initiation Protocol (SIP) control message.
