Which WAN connectivity technology is optimal for edge computing compared to others and why?
A.
Due to high bandwidth, separation and security, and proximity to the data center network, DWDM is the optimal WAN technology for edge computing compared to 4G/5G connectivity, which offers native separation and security with close proximity to the data center.
B.
Due to low latency, high bandwidth, and closest proximity to the user, 4G/5G connectivity is the optimal WAN technology for edge computing compared to L3 VPN MPLS connectivity, which offers native separation and security with close proximity to the data center.
C.
Due to low cost, high bandwidth, low latency, and closest proximity to the edge of the network, Mero Ethernet is the optimal WAN technology for edge computing compared to MPLS, which offers native separation and security with close proximity to the data center.
D.
Due to low latency, high bandwidth, and closest proximity to the user, L3 VPN MPLS connectivity is the optimal WAN technology for edge computing compared to 4G/5G connectivity, which offers native separation and security with close proximity to the data center.
IMO the answers are confusing, but the question is clear, what is the best WAN technology for Edge Computing. Meaning closest to the user.
The answers, focus on the 1st statement. Proximity to the data center, is not relevant in edge computing, which eliminates A.
The 2nd statement of B, C and D, specifically the term Security. I believe that would eliminate answers C and D, because of VPN. Leaving us with B.
Make any sense?
I think it's B:
Edge computing aims to bring computing resources closer to the end-users, improving latency and overall user experience. 4G/5G connectivity offers low latency, high bandwidth, and is closer to the users, making it an optimal choice for edge computing. Although L3 VPN MPLS connectivity provides separation and security, it may not offer the same low latency and close proximity to the user as 4G/5G connectivity.
I think A is correct answer .
B cant be cause 4G/5G has latency
C cant be cause its says metro compare to MPLS - MPLS is topology in wan/wan service and not a technology of wan.there isnt wan technology call MPLS .
D cant be cause L3VPN MPLS isnt wan technology - it is a topology of wan .
so i think A correct .
4G/5G has low/medium bw and medium latency, so it cannot be.
Metro Eth. has medium cost and medium/high bw, so I would also discard it.
Then, bw DWDM and MPLS I have doubts... MPLS closer to the user? Maybe, until CE router. And DWDM to the DC devices? Could be, it is related to interconnect DCs or CPDs. I don't know exactly bw this two, any help? Thanks
Edge computing == needs to be closer to user
A==> DWDM (for longer distances an overkill) vs 4g (no native separation-Internet traffic)
D ==> MPLS (an overkill as well) vs 4g (no native separation-Internet traffic)
