Consequently, a SIP REFER-Issuer generating a REFER request with multiple REFER-Targets SHOULD include the "norefersub" option-tag in a Require header field and

This document describes the conventions for using several Elliptic Curve cryptographic algorithms with the Cryptographic Message Syntax (CMS) encrypted key package content

Specifically, it includes conventions necessary to implement Elliptic Curve Diffie-Hellman (ECDH) with EnvelopedData and Elliptic Curve Digital Signature Algorithm (ECDSA)

If a downstream router receives multiple ECMP Redirects sent by different upstream routers, it SHOULD use the Preference, Metric, or other fields as specified below as

Any adversary that controls routers legitimately, or that can assume control of a router, is assumed to be able to effect the types of attacks described below.. Note that
