A new transport protocol s= hould help

 

- to alleviate, if not to = eliminate, the routing scalability problem,

 

-  to phase out NAT t= o eliminate processing delay caused by unnecessary middleboxes, and<= /p>

 

- to make more efficient u= tilization of abundant IPv6 addresses.


A new transport protocol called F= SP is proposed:

https://datatracker.ietf.org/doc/dra= ft-gao-flexible-session-protocol/


Detailed motivations of designing FSP is= explained in https://datatracker.ietf.org/doc/draft-gao-fsp-motivations/


In short, FSP is a connect= ion-oriented transport layer provides mobility, multi-homing and multi-path= support by introducing the concept of 'upper layer thread ID' (ULTID), whi= ch was firstly suggested in "Fuzzy-layering and its suggestion" (https://mailarchive.ietf.org/arch/msg/ietf/u-6i-= 6f-Etuvh80-SUuRbSCDTwg).

 

An integrity check code (I= CC) field associated with the ULTID is designed in the FSP header to protec= t authenticity and optionally privacy of the FSP packet. An FSP packet is a= ssumed to originate from the same source if the ICC value associated with certain destination ULTID passes validati= on, regardless of the source or destination address in the underlying layer= .

 

The ULTID is assigned roug= hly the same semantics with Security Parameter Index (SPI) in MOBIKE [RFC45= 55]. Either the weak key or the shared secret key is indexed by the source = or destination ULTID in the local context of the sender or the receiver, respectively.

 

FSP facilitates secret key= installation by introducing the concept of transmit transaction. Mechanism= of transmit transaction also provides the session-connection synchronizati= on service to the upper layer.



FSP effectively separates the identifier role and= routing locator role of the IPv6 address. The identifier role is localized= while the routing locator role is kept global. By supporting mobility and = multihoming at the transport layer it alleviates the routing scalability problem caused by supporting mobilit= y and multihoming at the network layer.


When implemented over IPv6 abundance of IPv6 addr= esses makes NAT obsolete. However FSP over UDP is still friendly to NAT.


FSP eliminates the concept of 'port number'<= /span>. Instead it proposes to take use of the lower 32 bits of the 128-bit IPv6 a= ddress as the 'upper layer thread ID'. It could considerably enhance alloca= tion efficiency of the IPv6 address space.
