User-controlled optical networks have flexibility of composing application-specific transport networks and using network resources from different suppliers. Each user independently owns and manages some network resources. A group of users can compose application-specific transport networks. The end-to-end connections between the users in the group are established in a fully distributed, peer-to-peer manner. There is no centralized network management authority to coordinate such end-to-end connection establishment. The management architecture of peer-to-peer optical networks is dramatically different than the existing centralized optical network management architectures.     This research is to explore the potentials of peer-to-peer technologies in the context of optical network management. Our research goal is to explore the technologies that enable to search optical network resources in a peer-to-peer manner, just as searching for music files. By taking into account the special requirements and characteristics of optical networks, we will customerize the existing peer-to-peer technologies for the management of peer-to-peer optical networks. Such technologies include discovery of group members, search of available network resources offered by group members, communications between group members, granting and receiving the resource management privileges, etc.     We plan to compare the economics and availability of peer-to-peer optical networks with those of carrier managed optical networks. By economics analysis of peer-to-peer optical networks, we want to reveal the benefits of user centric network management, when they take advantage of the diversity and competitions between carriers. The availability of peer-to-peer optical networks is different than that in a single carrier network. Although individual network resource may not be highly available, peer-to-peer optical networks enjoy massive redundancy of similar network resources and therefore potentially offer highly available services. We plan to analyze the availability of peer-to-peer optical networks using a new measurement.

用户控制的光网络可以灵活地组成特定应用的传输网络并使用不同供应商的网络资源。每个用户独立拥有和管理一些网络资源。一组用户可以组成特定于应用的传输网络。组内用户之间的端到端连接以完全分布式、点对点的方式建立。没有集中的网络管理机构来协调这种端到端连接的建立。对等光网络的管理架构与现有的集中式光网络管理架构有很大不同。     本研究旨在探索点对点技术在光网络管理背景下的潜力。我们的研究目标是探索能够以点对点方式搜索光网络资源的技术，就像搜索音乐文件一样。考虑到光网络的特殊要求和特点，我们将定制现有的点对点技术来管理点对点光网络。这些技术包括发现组成员、搜索组成员提供的可用网络资源、组成员之间的通信、授予和接收资源管理权限等。我们计划将点对点光网络与运营商管理的光网络的经济性和可用性进行比较。通过对点对点光网络的经济学分析，我们希望揭示以用户为中心的网络管理在利用运营商之间的多样性和竞争时所带来的好处。对等光网络的可用性与单运营商网络中的可用性不同。尽管单个网络资源可能不是高度可用的，但对等光网络享有类似网络资源的大量冗余，因此有可能提供高度可用的服务。我们计划使用新的测量方法来分析点对点光网络的可用性。
