Today's telecom services have rather high expectations for quality of service (QoS), especially as internet applications become increasingly sensitive to time and delays. Because they are real-time, the crucial nature of certain of these applications is more noticeable. These provide challenges to network operators and service providers; since they are required to not only deliver these services to users, but also to ensure the requirements for Quality of Service (QoS).rnThe majority of service providers and network operators run their networks using MPLS technology and label distribution protocols, which are complex to install, maintain, and troubleshoot. The IETF is standardizing an SR paradigm that is manageable and implemented on MPLS and is based on a simple control plane. SRTE implements the SR protocol and establishes a tunnel using TE constraints. In SR Policy, the Head-end learns multiple candidate paths from one or more segment lists, but only one path is instantiated in RIB/FIB. As a result, SR policy for TE is an effective method for engineering the packet path at the ingress router, and it is continually improving and enabling unprecedented control, as well as successfully leveraging the benefits of SR technology, which enhances more QoS requirements.rnThis research presents a comparative analysis of SRTE with SR in terms of average latency, jitter, and packet loss, and finds that SRTE has a 33% reduction in latency, a 7.3% reduction in packet loss, and a 15% reduction in jitter. Concerning the above attributes, the conclusion of the investigation revealed that SRTE appeared to be more capable in the optimization of traffic in Core Networks when implemented by service providers and network operators, based on the comparative results of network performance.
