“…Kualitas layanan (QoS) ialah sekumpulan teknologi yang bekerja pada jaringan untuk menjamin kemampuannya dalam melaksanakan aplikasi serta lalu lintas prioritas besar secara andal dalam kapasitas jaringan yang terbatas. Teknologi QoS mencapai hal ini dengan menyediakan penindakan yang berbeda dengan serta alokasi kapasitas buat aliran tertentu dalam lalu lintas jaringan, dalam menajemen jaringan terdapat sebagian parameter kuantitatif khususnya, delay, packet loss, troughpu, jitter serta Bandwitch yang mempunyai ikatan erat dengan kinerja jaringan QoS [4].…”

“…Meskipun kualitas layanan (QoS) telah diselidiki dan diimplementasikan pada jaringan TCP/IP dan pusat data [3], mekanismenya sebagian besar masih belum dijelajahi dalam konteks jaringan HPC. Pekerjaan kami adalah salah satu studi awal untuk menyelidiki peran kelas lalu lintas QoS dalam mengurangi variabilitas kinerja disebabkan oleh terputusnya komunikasi dalam jaringan hierarkis yang sekarang popular [4].…”

The Internet network during a pandemic as it is today is the main actor in all aspects. For example, obtaining information, economics, offices, education, and many more. On September 20, 2021, the City of Padang Panjang is included in the Level 3 area, sourced from the circular letter of the Minister of Home Affairs number 44 of 2021 concerning the implementation of restrictions on community activities at level 4, level 3, level 2, and level 1. level 3. 50% of the total number of employees in an office must be WFH (Work From Home) where employees continue to work as usual but stay at home. Then in the field of education 50% of students and teachers carry out online learning or lectures. From the explanation above, it has been illustrated how important a network is today. Employees can continue to work only from home by relying on the Internet Network. Students and students can still get an education even if they don't go to school and campus. And the Internet network plays a big role in that. Padang Panjang City currently has a Smart City program

“…QoS use in HPC networks is limited. Others have used QoS to prioritize traffic at the job level [18], [19] in simulated systems. We previously presented the first empirical investigation of QoS and its impact on network contention on a real HPC system [20], which showed a reduction in overall throughput, unlike the simulated approaches.…”

Jobs on most high-performance computing (HPC) systems share the network with other concurrently executing jobs. Network sharing leads to contention that can severely degrade performance. This article investigates the use of Quality of Service (QoS) mechanisms to reduce the negative impacts of network contention. QoS allows users to manage resource sharing between network flows and to provide bandwidth guarantees to specific flows. Our results show that careful use of QoS reduces the impact of network contention for specific jobs, resulting in up to a 40% performance improvement. In some cases, it completely eliminates the impact of contention. It achieves these improvements with limited negative impact to other jobs; any job that experiences performance loss typically degrades less than 5%, and often much less. Our approach can help ensure that HPC machines maintain high levels of throughput as per-node compute power continues to increase faster than network bandwidth.

“…Current interconnection networks carry not only traffic of applications such as backup or file transfer protocols, which does not require service differences, but also traffic from others like real-time protocols [9], MPI communications or traffic from users with different privilege levels in the system [10]. Therefore, QoS has become the focus of much discussion and research during the last decades [11,12]. A sign of this interest is the inclusion of support aimed to provide QoS on interconnection networks such as GE, IB and also OPA.…”

New hierarchical crossbar switch architectures, such as Omni-Path (OPA) and Cray X2, have appeared to improve packet latency, reduce overall cost and increase fault tolerance of the high-performance interconnection networks in supercomputing and data center systems. These and other interconnect technologies (Infiniband or 40/100 Gigabit Ethernet) include support to provide quality of service (QoS) to the applications. In this paper, we show how this QoS support can be enabled to achieve bandwidth and/or latency differentiation in Omni-Path interconnection networks, as a representative case of hierarchical switches. To do that, three different table-based schedulers are used. We include the description of these schedulers and a comparative study by using the results obtained when we evaluate them with Hiperion, a simulation tool that implements an OPA model.
