c. Sehubungan dengan trafik Speedy yang mempunyai prioritas layanan yang rendah, jika terjadi gangguan di jaringan maka trafik akan dilakukan fast reroute dengan delay yang lebih lama. Akan tetapi, hal ini lebih baik untuk mengurangi packet loss trafik Speedy yang ada di jaringan, dan tentunya tidak akan mempengaruhi kinerja layanan trafik lain, sehingga SLA Service Level Agreement trafik lain tetap terjaga kualitasnya. d. Hasil penelitian ini berperan penting pada pengembangan ilmu pengetahuan terutama pada bidang ilmu rekayasa trafik. Masalah-masalah di jaringan dapat teratasi melalui penerapan rekayasa trafik MPLS dengan DiffServ yang pada akhirnya akan meningkatkan kinerja dan ketahanan jaringan. Hasil akhir yang dicapai yaitu peningkatan kualitas layanan jaringan.

1.7. 5.2. Saran

Untuk penelitian lebih lanjut, hasil yang lebih akurat diharapkan dapat dicapai apabila kurva distribusi hasil pengukuran di lapangan dapat langsung diterapkan di simulator dengan menggunakan pendekatan differensial dan integral. Kurva distribusi yang dianalisis dengan metode differensial dan integral dapat digunakan untuk proyeksi trend peningkatan trafik ke depan. Di samping itu, penelitian lebih lanjut penerapan rekayasa trafik MPLS dengan DiffServ diharapkan dapat menerapkan mekanisme penyeimbangan beban load balancing. Hal ini sangat penting pada beban dimana sebagian saluran jaringan mengalami beban trafik berlebih overutilized, sedangkan sebagian lainnya tidak Universitas Sumatera Utara mengalami beban berlebih atau bahkan beban trafik dibawah beban rata-rata underutilized. Teknologi GMPLS Generalized MPLS merupakan saran penelitian lebih lanjut karena GMPLS hadir sebagai pengembangan kemampuan switching dari MPLS untuk dapat mengakomodasi switching non packet. Dengan demikian fungsi GMPLS bisa diinstal di berbagai perangkat berplatform optik seperti SONET ADM, OXC Optical Cross Connect dan perangkat yang ada dalam sistem DWDM. Hal ini berbeda dengan MPLS, yang hanya didukung terutama oleh router dan switch saja.
