Abstract
Data communication services have become increasingly critical for service providers, where Network availability must be maintained to guarantee uninterrupted connectivity between customer sites. In service provider environments utilizing Virtual Private Routed Network (VPRN) over Multi Protocol Label Switching (MPLS), gateway router failures can disrupt service operations and degrade customer productivity. To address this issue, this research analyzes the Implementation of the Virtual Router Redundancy Protocol (VRRP) as a failover mechanism on VPRN Networks running on Nokia Service Router OS, with the objective of ensuring continuous communication even during equipment failure. The method used in this study involves designing and simulating an MPLS– VPRN topology using GNS3 and virtual Nokia 7750 SR routers. MPLS-LDP and OSPF were deployed within the backbone, while BGP provided routing connectivity between customer domains. Three operational scenarios were tested— normal condition, failover (master router shutdown), and recovery—by generating ICMP and TCP traffic and measuring Quality of Service (QoS) parameters including throughput, packet loss, delay, and jitter according to ETSI/TIPHON standards. The results demonstrate that VRRP successfully performs automatic gateway switchover and preserves service Quality throughout the failover process with failover times between 1.6 s and 5 s. The throughput remained within 2237.66– 2374.15 Kbps, packet loss remained extremely low at 0.001917–0.002529%, delay ranged from 5.3–7.9 ms, and jitter recorded values between 0.00645–0.01377 ms. Based on TIPHON assessment criteria, all metrics fall under the Excellent category. Therefore, VRRP is proven to be an effective Redundancy mechanism for improving Network resilience and maintaining service performance in MPLSbased VPRN Implementations on Nokia SR OS. Keywords: VRRP, VPRN, MPLS, Nokia SR OS, failover, QoS, throughput, delay, packet loss, jitter Layanan komunikasi data berbasis jaringan menjadi bagian penting dalam operasional penyedia layanan, di mana ketersediaan konektivitas antar-site pelanggan harus tetap terjaga kapan pun. Pada jaringan penyedia layanan dengan arsitektur Virtual Private Routed Network (VPRN) berbasis Multi Protocol Label Switching (MPLS), kegagalan router gateway dapat mengakibatkan gangguan layanan dan berdampak pada produktivitas pelanggan. Untuk mengatasi permasalahan tersebut, penelitian ini menganalisis penerapan protokol redundansi Virtual Router Redundancy Protocol (VRRP) sebagai mekanisme failover pada VPRN berbasis Nokia Service Router OS, dengan tujuan memastikan jalur komunikasi tetap berjalan meskipun terjadi kerusakan perangkat. Metode penelitian dilakukan dengan merancang dan mensimulasikan jaringan MPLS–VPRN menggunakan GNS3 dan router virtual Nokia 7750 SR. Protokol MPLS-LDP dan OSPF digunakan dalam backbone, sedangkan BGP menjadi penghubung layanan pelanggan. Pengujian dilakukan melalui tiga kondisi, yaitu kondisi normal, skenario failover (router master dimatikan), dan skenario pemulihan. Data lalu lintas dikirim menggunakan ICMP dan TCP, dengan pengukuran parameter Quality of Service (QoS) meliputi throughput, packet loss, delay, dan jitter berdasarkan standar ETSI/TIPHON. Hasil penelitian menunjukkan bahwa VRRP melakukan perpindahan gateway secara otomatis dan mampu menjaga kualitas layanan tetap stabil dengan waktu failover 1,6s-5s. Nilai throughput berada pada kisaran 2237,66–2374,15 Kbps, packet loss sangat kecil yaitu 0,001917–0,002529%, delay rata-rata 5,3–7,9 ms, dan jitter hanya 0,00645–0,01377 ms. Berdasarkan standar TIPHON, semua parameter berada pada kategori Sangat Baik, sehingga dapat disimpulkan bahwa penerapan VRRP pada jaringan MPLS-VPRN Nokia SR OS efektif meningkatkan ketahanan jaringan dan meminimalkan dampak kegagalan perangkat.
