    abstract =  {This document defines a new Traffic Selector (TS) Type for Internet Key Exchange version 2 to add support for negotiating Mandatory Access Control (MAC) security labels as a traffic selector of the Security Policy Database (SPD). Security Labels for IPsec are also known as "Labeled IPsec". The new TS type is TS\_SECLABEL, which consists of a variable length opaque field specifying the security label. This document updates the IKEv2 TS negotiation specified in RFC 7296 Section 2.9.},
