Abstract
A system and a method of dynamic bandwidth allocation in the passive optical network comprising a SDN controller (112) to switch a first subscriber of the subscriber group (102) from a first passive optical network (PON) port to a second PON port at the OLT (116) when a first bandwidth availability at the first PON port is less than a predefined bandwidth and a second bandwidth availability at the second PON port is more than the predefined bandwidth. In particular, the predefined bandwidth is a required bandwidth by the first subscriber.
Claims14
A system (100) of dynamic bandwidth allocation in the passive optical network, wherein the system (100) comprising a subscriber group (102), an optical network unit (ONU) (104), a software-defined network (SDN) controller (112) and an optical line terminal (OLT) (116),
- wherein the SDN controller (112) operably configured to:
- switch a first subscriber of the subscriber group (102) from a first passive optical network (PON) port to a second PON port at the OLT (116) when a first bandwidth availability at the first PON port is less than a predefined bandwidth and a second bandwidth availability at the second PON port is more than the predefined bandwidth,
- wherein the predefined bandwidth is a required bandwidth by the first subscriber.
A method for dynamic bandwidth allocation in a passive optical network, wherein the method comprising:
- switching, by a software-defined network controller (112), a first subscriber from a first passive optical network (PON) port to a second PON port at an optical line terminal (OLT) (116) when a first bandwidth availability at the first PON port is less than a predefined bandwidth and a second bandwidth availability at the second PON port is more than the predefined bandwidth, and
- wherein the predefined bandwidth is a required bandwidth by the first subscriber.
