Many overseas fiber isp using IPoE because no overhead like PPPoE. Why in fiber internet in Malaysia still using PPPoE?
Limitation of PPPoE: 1. Overhead, small MTU size 2. Single Threaded, no acceleration, make router CPU work hard 3. Since single thread, induce additional latency when in high speed 4. Prone to disconnect in high speed active sessions 5. Cannot use packet inspection/protection, PPPoE force to run as software, not hardware.
Yes, identify user at ONU side (DHCP Identity) and user simply change router and set WAN as DHCP, is more like Plug n Play, no need to remember Username and Password More important, no unconditional disconnect like PPPoE did, horrible while playing games
Agree on all the downsides you stated but ISPs here use PPPoE because it was the most compatible accounting method that would directly integrate into their existing billing and customer record management systems. In the case of Unifi, TM is paying the price for this decision in the form of constant capacity and hardware upgrades to the PPPoE access concentrator/BRAS as each of these devices need to handle 60-80k concurrent PPPoE sessions per zone on average.
The other reason is security. Security policies such as unicast reverse-path forwarding to prevent IP spoofing is easier to implement when all your customer traffic is isolated within a PPPoE session. IPOE requires all your devices on the access network to be DHCP aware and to filter incoming traffic based on the DHCP lease that was issued to the client device. Your DHCP relays also need to assign IP addresses on a per-subscriber circuit ID basis (see DHCP Option 82) rather than by MAC address to prevent lease exhaustion attacks (remember, if you're not doing CGNAT you're issuing public IPv4 addresses here).
It's also more difficult to achieve all of this when you go with a multi-vendor (Huawei/Alcatel/Fiberhome) and multi-access technology (GPON/VDSL2) deployment.

Understood, plus ISP driven from DSL which is they can use same machine. Year 2020, PPPoE not develop to Hardware Accelerated, beside NAT Hardware Accelerated.
Correct me if I'm wrong. Maxis own infra and DSL fixed network uses IPoE instead.
IPoE is more suitable for ISPs which own the entire network from backend to the last mile especially cable TV networks, non sharing fibre infra and fixed wireless. It trades simplicity and easy management for flexibility. Role example of successful networks in the world that have now adopted IPoE instead of PPPoE for its modernization is NTT West/East Japan which is already embarking on full migration to IPv6 IPoE deployment to all its fibre users.
Having said that unlike Japan, South Korea, Taiwan and Thailand where you can see multiple ISPs serving homes on their own independent networks unlike our failed TM's countrywide wholesale HSBB monopoly, it is not surprising that in these countries you can see multiple fibres owned by different ISPs running in front of your homes offering you cable tv internet, FTTH or massive MIMO fixed wireless on different independent networks.
Malaysian and Singaporean open network build-outs are more westernized than theirs.
The strategy adopted by Japan and China is that it seeks simplicity by unifying all internet services under the IP umbrella(IPTV based cable TV, VoIP, ubiquitous mobile EPC and internet access)
The western approach was to separate multiple services through different approach with different wavelengths, packets and VLAN tagging which makes things further complicated trying to sell sophistication with lesser overheads. The result is a more expensive adoption and much more complicated model.
Over time, we know who is winning between both sides.
Isps in singapore all use IPoE. the authentication is done by ONU SN and PW pair instead, which is not possible in current unifi infrastructure where the same password is shared by ONUs connected to the same port on the OLT.

Unifi assign different ONU Password/SLID for every ONU. you can check your and your neighbour if u want.
Unifi also using IPoE for both of VoBB and HyppTV, only Internet they are using PPPoE
