【摘要】：现有网络设备支持的协议体系庞大,导致网络系统高度复杂,这不仅限制了网络技术的发展,也无法满足当前云计算、大数据和服务器虚拟化等应用需求.社会经济的驱动、信息通信技术的发展、硬件成本的降低以及开放资源的兴起,不仅使得网络系统向高度动态及灵活的方向发展,而且也意味着新的网络服务商进入信息技术市场的门槛降低,新兴的商业模式及合作竞争模式即将形成.然而,现实的各类网络系统变得越来越复杂,相应的工程复杂性或社会复杂性越来越高,以及网络系统的多领域、动态性和不可预测性等特性,使得网络系统成为一个巨大的复杂系统,很难对改善网络问题的方案事先进行较为全面和准确的评估和修正.为此,将平行系统理论引入到网络系统.平行网络(parallel networks)作为一种最新网络架构,通过人工网络与实际网络的实时信息传递及相互优化,以及对网络系统控制面、转发面和应用层功能进行重新定义抽象,使得网络管理软件可编程,实现对不同层次需求、不同服务内涵的网络进行实时的决策指导及行为优化,从而满足用户不断变化的网络服务需求.
[Abstract]:The huge protocol system supported by the existing network devices leads to the high complexity of the network system, which not only limits the development of network technology, but also can not meet the current needs of cloud computing, big data and server virtualization and other applications. The drive of social economy, the development of information and communication technology, the reduction of hardware cost and the rise of open resources not only make the network system develop in a highly dynamic and flexible direction. It also means that the threshold for new network service providers to enter the information technology market will be lowered, and a new business model and cooperative competition mode will soon be formed. However, all kinds of network systems are becoming more and more complex, the corresponding engineering complexity or social complexity is becoming higher and higher, and the multi-domain, dynamic and unpredictable characteristics of the network system. It makes the network system become a huge complex system, and it is difficult to evaluate and correct the scheme to improve the network problem in advance. Therefore, parallel system theory is introduced into network system. Parallel network (parallel networks), as a new network architecture, redefines and abstracts the functions of network control surface, forwarding surface and application layer through real-time information transmission and mutual optimization between artificial network and real network. The network management software can be programmed to realize the real-time decision guidance and behavior optimization for the network with different levels of requirements and different service connotations, so as to meet the changing network service requirements of users.
