Analysis of SRv6 Deterministic Network Scenarios

Conceptualization of Deterministic Networking (DN), has developed as the central paradigm of the contemporary architecture of the network, which proposes precise Quality of Service (QoS) that adheres to the requirements of high precision applications, which include not only telemedicine surgeries and autonomous driving but also industrial automation. In this context, SRv6 Deterministic Networking arises as a transformational technology essentially using Segment Routing over IPv6 (SRv6) in computation of end-to-end paths custom-built for specific service requirements hence ensuring strictest Service Level Agreement (SLA) compliance. This paper proposes a hierarchical-based end-to-end deterministic networking scheme to heterogeneous scenarios using SRv6 technology. Each of the heterogeneous network domains is abstracted as separate objects, through utilization of that novel scheme, and at the same time, makes it associated with a parent controller to carry out intra-domain management. Emerging controllers collect information in details about different topologies and also SLA metrics present inside the network thus helping to make a decision during path computation and allocation of resources. The scheme is then tested for its efficacy on the CENI test network in a laboratory setting. Testing generates strong statistics, which reveal that the performance of the network latency addition is below 100 milliseconds, network reliability is at 99.999%, and the capacity to support a network bandwidth of more than 100 gigabits per second. Specifically, the scheme achieves remarkable performance from the Yangtze River Delta region to the Beijing-Tianjin-Hebei regional network, with latency within 100 milliseconds and jitter under 10 milliseconds, effectively meeting the stringent real-time demands of diverse applications. This paper proposes an alternative to bridge the heterogeneous networks with SRv6 Deterministic Networking that allow provision of source-to-destination and destination-to-source paths in a reliable way so as to strictly guarantee SLAs. The proposed scheme made possible through laboratory testing would not only advance the state-of-the-art in DN but also stands a promising approach to addressing the evolving needs of the modern network infrastructures.
