Today's telecom operators are facing an increasing need to provide users with dynamic and high-capacity network connectivity services. This is mainly driven by deployment of the FTTx technologies and the emergence of ever more bandwidth demanding, dynamic and heterogeneous e-services such as 3D games, virtual worlds, and network based high quality media applications such as HD and UHD IPTV.As 100 Gbps Ethernet is becoming commercially available, researchers are focusing on 1Tbps transport by investigation solutions for achieving bit rates at 100Gbps and beyond per wavelength channels which can be deployed in a dynamic network environment. A promising solution for transmission of high bit rate at 100Gbps and beyond per channel is optical orthogonal frequency division multiplexing (O-OFDM). It can take advantage of multi-level modulation schemes; enable the efficient compensation of transmission impairments and also adaptation of data rate and transmission format of the transmission channel. This features make the O-OFDM technology an attractive solution for future optical Internet where dynamic bandwidth allocation is requiredThe PATRON proposal combines advantage of multi-level modulations, Optical OFDM multiple Access (O-OFDMA) concept and network elements programmability and proposes an advanced programmable optical transmitter and receiver capable of transmitting different user data with different bit rates and different modulation format in a dynamic O-OFDMA core network. The research novelties of this project are:1- Design and implement a programmable O-OFDMA transmitter and receiver that can be attached to a commercial electronic edge router or optical cross connect and constitute edge or core router of an O-OFDMA network.2-Deployment and adaptation of O-OFDMA technology in core optical networks by proposing a novel transmitter/receiver capable of mapping real time data from metro/access network into high speed subcarriers at different wavelength channels in a core O-OFDMA network3- Core network programmability through on-demand and programmable network partitioning and bandwidth allocation with fine granularity at wavelength and subcarrier level enabled by the proposed transmitter/receiverThe major outcome of this project will be an implementation of a programmable O-OFDMA transmitter and receiver supporting the above functionalities, which will be demonstrated and validated in a lab trial.The outcome of PATRON project can potentially enable network network operators to partition their network to several segments, each with different bandwidth and QoS capability. The partitioning criteria such as bandwidth and QoS can be defined based on user or application requirementsThis proposal aims to open a new field of research for the Principle Investigator (PI) inline with the current activities within High Performance Networking Group (HPNG) in University of Essex. . The outcomes of PATRON will enable the PI to advance the HPNG rich portfolio in two dimensions: 1- high-speed optical transport for future core optical network based on optical OFDM technology and 2- programmable and application-ware optical networking for future Internet based on optical OFDMA technology. It will enable the PI to build his own independent research field by further developing the novel concept of optical core network infrastructure partitioning using O-OFDMA networking technology.

今天的电信运营商面临着为用户提供动态、大容量网络连接服务的日益增长的需求。这主要是由于FTTx技术的部署和更多带宽要求更高、动态和不同种类的电子服务的出现，如3D游戏、虚拟世界和基于网络的高质量媒体应用，如HD和UHD IPTV。随着100 Gbps以太网开始商业化，研究人员正通过调查解决方案将重点放在1Tbps传输上，以实现可在动态网络环境中部署的每波长通道100Gbps及更高的比特率。光正交频分复用(O-ofdm)是一种很有前途的解决方案，可以实现每信道100Gbps以上的高比特率传输。它可以利用多级调制方案；实现传输损伤的有效补偿以及传输信道的数据速率和传输格式的适配。该方案结合了多级调制、光分多址(O-OFDMA)概念和网元可编程性的优点，提出了一种先进的可编程光发射机和接收机，能够在动态的O-OFDMA核心网中以不同的比特率和不同的调制格式传输不同的用户数据。设计并实现了一种可编程的O-OFDMA发射机和接收机，它可以连接到商用的电子边缘路由器或光交叉连接上，构成O-OFDMA网络的边缘路由器或核心路由器。2-O-OFDMA技术在核心光网络中的部署和适配，提出了一种新型的发射机/接收机，能够将来自城域/接入网络的实时数据映射到核心O-OFDMA网络中不同波长信道的高速子载波中。3-核心网络可编程，通过按需和可编程的网络划分和带宽分配，在波长和副载波级实现细粒度的带宽分配拟议的发射机/接收机本项目的主要成果将是实现支持上述功能的可编程O-OFDMA发射机和接收机，这将在实验室试验中得到演示和验证。Patron项目的结果可能使网络运营商能够将其网络划分为几个网段，每个网段具有不同的带宽和服务质量能力。带宽和服务质量等划分标准可以根据用户或应用程序的需求来定义。这项提议旨在为首席调查员(PI)开辟一个新的研究领域，以符合埃塞克斯大学高性能网络小组(HPNG)目前的活动。。PATRON的成果将使PI能够在两个维度上推进HPNG丰富的产品组合：1-基于光OFDM技术的未来核心光网络的高速光传输，以及2-基于光OFDMA技术的未来互联网的可编程和应用软件光网络。通过进一步发展利用O-OFDMA组网技术的光核心网基础设施划分的新概念，使PI能够建立自己的独立研究领域。
