Hi Joel, 

Thanks for your comment. 

Actually the word "such" in that sentence refers to a set of candidate technologies in the underlay, TSN and FlexE are just two examples. We could rephrase that sentence to make it clear. How about: 

"The usage of such type of underlying technologies... "?

Best regards,
Jie
