The Broadband Photonics project (BBP) under the Freeband consortium of projects looks into the design of an extended access network. The network is a photonic network which can be dynamically reconfigured to distribute bandwidth in an optimised manner. This paper presents linear programming based formulations to calculate implementation of bandwidth redistribution in the network.

Passive Optical Networks (PONs) are a preferred architecture for distribution of bandwidth in the access network. The BSIK Freeband Broadband Photonics Project (BBP) looks at the design of a flexible DWDM PON which can be used to increase the bandwidth provided to the user. We present a control and management scheme for such a network which operates with the IEEE Ethernet Passive Optical Network (EPON) protocol. The design emphasis is on implementing such a scheme with a cost effective and practical approach.

The paper discusses the merits of having a reconfigurable access network. The network is viewed as a stack of logical PONs in which bandwidth can be redistributed on an inter-PON scale. The redistribution allows for optimal distribution of bandwidth to the end user.
