Abstract:

&nbsp;&nbsp;&nbsp;This&nbsp;draft&nbsp;proposes&nbsp;a&nbsp;service&nbsp;affinity&nbsp;solution&nbsp;between&nbsp;client&nbsp;and
&nbsp;&nbsp;&nbsp;server&nbsp;based&nbsp;on&nbsp;Transport&nbsp;Layer&nbsp;Security&nbsp;(TLS).&nbsp;&nbsp;An&nbsp;extension&nbsp;to
&nbsp;&nbsp;&nbsp;Transport&nbsp;Layer&nbsp;Security&nbsp;(TLS)&nbsp;1.3&nbsp;to&nbsp;enable&nbsp;session&nbsp;migration.&nbsp;&nbsp;This
&nbsp;&nbsp;&nbsp;mechanism&nbsp;is&nbsp;designed&nbsp;for&nbsp;network&nbsp;architectures,&nbsp;particularly&nbsp;for
&nbsp;&nbsp;&nbsp;multi-homed&nbsp;servers&nbsp;that&nbsp;possess&nbsp;multiple&nbsp;network&nbsp;interfaces&nbsp;and&nbsp;IP
&nbsp;&nbsp;&nbsp;addresses.

&nbsp;&nbsp;&nbsp;This&nbsp;document&nbsp;also&nbsp;introduces&nbsp;a&nbsp;Reliable&nbsp;Framing&nbsp;Layer&nbsp;that&nbsp;operates
&nbsp;&nbsp;&nbsp;above&nbsp;the&nbsp;TLS&nbsp;record&nbsp;layer&nbsp;to&nbsp;provide&nbsp;message&nbsp;framing,&nbsp;sequence
&nbsp;&nbsp;&nbsp;numbering,&nbsp;acknowledgment&nbsp;tracking,&nbsp;and&nbsp;automatic&nbsp;retransmission.
&nbsp;&nbsp;&nbsp;The&nbsp;Framing&nbsp;Layer&nbsp;ensures&nbsp;zero&nbsp;application&nbsp;data&nbsp;loss&nbsp;during&nbsp;TLS
&nbsp;&nbsp;&nbsp;session&nbsp;migration&nbsp;by&nbsp;buffering&nbsp;unacknowledged&nbsp;data&nbsp;frames&nbsp;and
&nbsp;&nbsp;&nbsp;retransmitting&nbsp;them&nbsp;to&nbsp;the&nbsp;new&nbsp;server&nbsp;endpoint&nbsp;after&nbsp;migration
&nbsp;&nbsp;&nbsp;completes.
