“…Their analytical results show that diversity coding and network coding can be more cost-efficient, i.e., they require about 5-20% less reserved bandwidth. The delay impact of 1+1 path protection in MPLS networks has been investigated in [17]. McGettrick et.…”

1+1 protection is a method to secure traffic between two nodes against failures in between. The sending node duplicates the traffic and forwards it over two disjoint paths. The receiving node assures that only a single copy of the traffic is further forwarded to its destination. In contrast to other protection schemes, this method prevents almost any packet loss in case of failures. 1+1 protection is usually applied on the optical layer, on Ethernet, or on MPLS. In this work we propose the application of 1+1 for P4-based IP networks. We define an 1+1 protection header for that purpose. We describe the behavior of sending and receiving nodes and provide a P4-based implementation for the Behavioral Model version 2 (bmv2) software switch and the hardware switch Tofino Edgecore Wedge 100BF-32X. We illustrate how to secure traffic, e.g. individual TCP flows, on the Internet with this approach. Finally, we present performance results showing that the P4-based implementation efficiently works on the Tofino Edgecore Wedge 100BF-32X.

A strong power dispatching communication network with high speed becomes the premise of the establishment of a reliable Wide Area Monitoring System (WAMS). Signal transmission of Phasor Measurement Unit (PMU) is taken into account in different collective layers in this paper. The time delay modes based on Multi-Protocol Label Switching-Virtual Private Network (MPLS VPN) and point-to-point 2M link illustrate that the time delay of the former is better than the latter. Building the VPN network under MPLS can provide quality of service and ensure the stable transmission of real-time signal through traffic engineering, differentiated services and the protection function in MPLS layer with virtual route. The time delay character of "1+1" protection on the MPLS layer is also analyzed in this paper.
