firstly we are Viettel corporate which is the greatest telco in VN. Our products span military and civilian equipment. In terms of that, our branch company, Viettel High Tech, is responsible for designing the Online charging system, which is the heart of telco services. Every usage action of customers is reflected in charging requests, which are around 100 million accounts and result in nearly 100k transactions per second peak.
this leads us to the class of mesh problem that can be linear scalable to give the end user the same response time at a large system scale.in terms of ¡°the heart¡±, we are a core system that is behind many overlay infrastructure systems, therefore our product is set under very strict SLA and KPI.
More specifically, to achieve the ability to support 5G categories, the OCS needs to deliver latency that obeys the URLLC standard.
URLLC is a hard-to-archive KPI in 5G for software components, especially on the way to the cloud, where everything needs to be generalized and more slowly.
This urges us to renovate our lib connection underlying the core services app to deliver end-to-end acceptable latency at scale.
