摘要
目前的传输网络虚拟化解决方案主要依靠VLAN (Virtual Local Area network)和VPN (Virtual Private network)技术,实现逻辑上的隔离连接,实现数据流量隔离。然而,在公共基础设施之上共存的VLAN/ vpn可能会竞争相同的物理资源,并导致性能下降,特别是在拥塞的情况下。本文介绍了Flex-Ethernet (Flex-E),并研究了它作为候选接口解决方案的使用,以促进传输网络中的“硬”切片。这项研究揭示了Flex-E如何与新开发的技术(如分段路由(SR))一起,在严格的性能保证下实现动态路径分配。并阐述了标准化的差距和开放的挑战。
Towards Slicing for Transport Networks: The Case of Flex-Ethernet in 5G
Current solutions for network virtualization in the transport network relies on Virtual Local Area Network (VLAN) and Virtual Private Network (VPN) technologies, which facilitate logically isolated connectivity, providing data traffic seperation. However, co-existing VLAN/VPNs on top of a common infrastructure may compete for the same physical resources and introduce performance degradation, especially in case of congestion. This paper introduces Flex-Ethernet (Flex-E) and investigates its use as candidate interface solution for facilitating “hard” slicing in transport networks. This study sheds light on how Flex-E together with newly developed techniques like Segment Routing (SR), can enable a dynamic path allocation with strict performance guarantees. The standardization gaps and open challenges are also elaborated.
