A Large―Scale NFV―Based Emulation Platform for Smart Identifier Network 　　Abstract Network emulation is significant because of its ability to study network architecture running on real operating system and the whole protocol stack. However， conservatively allocating a physical network equipment for a corresponding emulation network is costly， scale?limited and rigid. In this paper， based on network function virtualization （NFV）， we present a large?scale emulation platform for the Smart Identifier Network （SINET）. We pool and virtualize all hardware resources by lightweight virtualization technology. Controllers and orchestrators are designed to manage emulation and collect monitored SINET emulation results. The controllers are used to implement dynamically synchronously management for large?scale emulation network and link characteristics. The orchestrators are utilized to achieve overload avoidance and green computing with the Xiao’s dynamic resource allocation algorithm. We implement flexibly programmable and dynamically configurable emulation. 中国论文网 /1/viewhtm　　Keywords NFV； SINET； emulation； virtualization； control； orchestration 　　T1 Introduction 　　he current problems of the Internet are a natural consequence of its architecture， which was designed to address the simple data communication needs 40 years ago [1]. The basic requirement of the Internet at that time was merely forwarding data packets among limited trust hosts. With the growth of the Internet， enormous technological innovations in both the application and network layers have emerged， which gives rise to new requirements from the architecture， such as support for trust， security， mobility and low energy consumption. However， the Internet was never designed to meet these requirements. To help evolve the Internet， there are enormous patches made for the current Internet architecture， such as Transport Layer Security （TLS）， Content Delivery Network （CDN） and Network Address Translation （NAT）.
