New TCP Enhancements Coming in Windows 10 Anniversary

These new concepts for TCP communication shouldn’t cause too much headache for current network infrastructure, but for anyone working with technology in a business environment, you should be aware that there are several enhancements coming with the August update for Windows 10 that’ll you might need to deal with.

Microsoft lays out the enhancements and changes in a blog post that introduces the new features and provides descriptions for each.

The 5 new features are:

  1. TCP Fast Open (TFO) for zero RTT TCP connection setup. IETF RFC 7413
  2. Initial Congestion Window 10 (ICW10) by default for faster TCP slow start
  3. TCP Recent ACKnowledgment (RACK) for better loss recovery (experimental IETF draft)
  4. Tail Loss Probe (TLP) for better Retransmit TimeOut response (experimental IETF draft)
  5. TCP LEDBAT for background connections IETF RFC 6817

The new features are intended to help improve overall network communications for Windows 10 clients. To get a handle on how these will shape the network of the future, read: Announcing: New Transport Advancements in the Anniversary Update for Windows 10 and Windows Server 2016
