电信运营商单体架构到微服务架构转型设计思路

微服务架构是一种适用于在云中部署应用和服务的组件化架构模式,它提倡将单一应用程序划分成一组小的服务,服务之间互相协调、互相配合,为用户提供最终价值.每个服务运行在其独立的进程中,服务与服务间采用轻量级的通信机制互相沟通.每个服务都围绕着具体业务进行构建,并且能够被独立的部署到生产环境、类生产环境等.另外,应当尽量避免统一的、集中式的服务管理机制,对具体的一个服务而言,应根据业务上下文,选择合适的语言、工具对其进行构建.

Concast: design and implementation of an active network service

Concast is a network layer service that provides many-to-one channels: multiple sources send messages toward one destination, and the network delivers a single “merged” copy to that destination. As we have defined it, the service is generic but the relationship between the sent and received messages can be customized for particular applications. We describe the concast service and show how it can be implemented in a back ward-compatible manner in the Internet. We describe its use to solve a problem that has eluded scalable end-system-only solutions: collecting feedback in multicast applications. Our preliminary analysis of concasting effectiveness shows that it provides significant benefits, even with partial deployment. We argue that concast has the characteristics needed for a programmable service to be widely accepted and deployed in the Internet     

The evolution of multicast: from the MBone to interdomain multicastto Internet2 deployment

Multicast communication-the one-to-many or many-to-many delivery of data-is a hot topic. It is of interest in the research community, among standards groups, and to network service providers. For all the attention multicast has received, there are still issues that have not been completely resolved. One result is that protocols are still evolving, and some standards are not yet finished. From a deployment perspective, the lack of standards has slowed progress, but efforts to deploy multicast as an experimental service are in fact gaining momentum. The question now is how long it will be before multicast becomes a true Internet service. The goal of this article is to describe the past, present, and future of multicast. Starting with the Multicast Backbone (MBone), we describe how the emphasis has been on developing and refining intradomain multicast routing protocols. Starting in the middle to late 1990s, particular emphasis has been placed on developing interdomain multicast routing protocols. We provide a functional overview of the currently deployed solution. The future of multicast may hinge on several research efforts that are working to make the provision of multicast less complex by fundamentally changing the multicast model. We survey these efforts. Finally, attempts are being made to deploy native multicast routing in both Internet2 networks and the commodity Internet. We examine how multicast is being deployed in these networks     

Carrier-grade Ethernet challenges for IPTV deployment

Carrier-grade Ethernet standardization and deployment is gaining momentum due to the ease of deployment, lower cost, and compatibility with existing networks on the access end. When Internet protocol television (IPTV) is deployed using Ethernet as the underlying interconnect fabric infrastructure, meeting fine-grained traffic management (TM) requirements on the service provider side to meet quality of service (QoS), billing, and security features implementation on the user side poses several challenges. Such challenges could be met using the TM features built into network processors (NPs).     

Introducing new Internet services: why and how

Active networks permit applications to inject programs into the nodes of local and, more important, wide area networks. This supports faster service innovation by making it easier to deploy new network services. In this article, we discuss both the potential impact of active network services on applications and how such services can be built and deployed. We explore the impact by suggesting sample uses and arguing how such uses would improve application performance. We explore the design of active networks by presenting a novel architecture, ANTS (active network transport system), that adds extensibility at the network layer and allows for incremental deployment of active nodes within the Internet. In doing so, ANTS tackles the challenges of ensuring that the flexibility offered by active networks does not adversely impact performance or security. Finally, we demonstrate how a new network service may be expressed in ANTS

Infrastructure for Intelligent Automation Services in the Smart Grid

The electricity grid is undergoing a radical transformation from a production-driven to a demand-driven energy delivery platform known as the smart grid. The integration of a large amount of renewable and distributed energy resources, together with new patterns of electricity production, accentuates the need for research in information and communication technologies to control bi-directional energy flows. The European FP7 project: “Energy Demand Aware Open Services for Smart Grid Intelligent Automation” is contributing to this research by providing an intelligent infrastructure for service deployment for the smart grid. The project defines a system architecture that provides interoperability between wireless sensors in home area networks connected over the Internet to a service provider function deployed in a cloud infrastructure. A key component in this infrastructure is the Home Energy Controlling Hub that, on the one hand, provides a platform for monitoring and aggregation of electricity consumption data from devices and appliances and, on the other hand, is the link between the deployed intelligent automation services and the home. To ensure openness and simplicity, the proposed infrastructure is based on the representational state transfer style architecture. This is adopted by implementing the emerging ZigBee IP and Smart Energy Profile 2.0 standards that to a wide extend conform with the Internet Protocol suite and state-of-the art web services development.
