Tesla has a not-so-secret plan to replace a fundamental-but-flawed building 
block of the Internet  Musk's Exascale DOJO supercomputer will use TTPoE 
instead of the universal TCP and wants the world to embrace it

Description:
Tesla wants to replace TCP with its own Tesla Transport Protocol over 
Ethernet (TTPoE) designed for its DOJO supercomputer.

FULL STORY
======================================================================

Tesla is looking to replace the widely-used Transmission Control Protocol 
(TCP) with its own offering. 

The company says Tesla Transport Protocol over Ethernet (TTPoE) is designed 
to support high-speed, low-latency communication, especially in environments 
where reliable data transfer is essential. 

TTPoE, integral to Teslas DOJO supercomputer, is optimized for the specific 
demands of Teslas systems, but Elon Musks firm is promoting it as a potential 
new standard for broader use beyond its own operations. UltraEthernet 
Consortium 

TTPoE is executed entirely in hardware and aids efficient data transmission 
across Ethernet networks without requiring special switches, instead using 
standard Layer 2 transport. Unlike lossless RDMA networks, TTPoE anticipates 
packet loss and includes mechanisms to retry transmissions, making it 
distinct from traditional protocols like TCP or UDP. 

TTPoE offers enhanced security features, such as encryption and 
authentication, to protect data integrity. This makes it particularly useful 
in automotive and industrial applications where managing large data sets 
securely and efficiently is essential. 

The protocol also supports scalability, allowing it to meet the growing data 
demands of modern electric vehicles, including those needed for autonomous 
driving and over-the-air updates. 

The latest information about TTPoE comes from ServeTheHome , which reported 
on Teslas presentation at the Hot Chips 2024 symposium in Stanford, 
California. Tesla shared details about TTPoEs architecture and suggested that 
TTPoE could offer lower one-way write latency over switches, including 
NVLink. It also announced its participation in the UltraEthernet Consortium 
(UEC).

Patrick Kennedy noted, This is one of those interesting talks, but at some 
point it would be cool if this was used beyond just DOJO. It feels like a lot 
of lifting to do making custom NICs, custom protocols, and so forth for a 
system and not trying to benefit from economies of scale. It was cool to see 
that Tesla is bringing this to the UltraEthernet Consortium. More from
