### Week 10,11,12 : Mid Term and Projects Break
:::info
Mid Term Test preparation break, also a lot of projects needed to be finished for my upcoming competition and my academic life. There are also some personal problems that require my attention. No worries, I still have high spirits for TEEP 2021, and for sure i will keep up after the break is over.

### Week 15-17 : Dive Deep Into E2 Manager
:::info
E2 Manager is arguably the most important component of Near RT-RIC. There are a lot of components in E2 Manager that each has its own functions. The purpose of week 15-17 study is to make a simple dictionary of each functions associated with E2 Manager.

Goals :
1. To further understand workflow of each RIC Component
2. To further understand the meaning behind Routing Table generated to/from E2 Manager
