One of the latest trends attacking Internet security is the
increasing prevalence of Denial of Service (DoS) attacks. DoS
attacks target system and/or network resources and seek to
prevent valid access by consuming resources. Internet Service
Providers (ISPs) need to be equipped and ready to assist in
tracing these attacks with tools and procedures in place before
the occurrence of a DoS attack. This paper proposes a proactive
inter-network communication method to integrate existing
tracing mechanisms across ISP boundaries to identify the source(s)
of an attack. The various methods implemented to trace attacks must
be coordinated both on the ISPs network as well as provide a
communication mechanism across network borders. It is imperative
that ISPs have quick communication methods defined to enable
neighboring ISPs to assist in tracking a security incident across
the Internet. This proposal makes use of current tracing practices
for traffic and performance management, which could be extended
for DoS incident handling. Policy guidelines for handling these
incidents are recommended and can be used by Internet Service
Providers (ISPs) and extended to their clients in conjunction with
the technical recommendations.

NOTE: The mail server at ietf.org can return the document in
MIME-encoded form by using the "mpack" utility. To use this
feature, insert the command "ENCODING mime" before the "FILE"
command. To decode the response(s), you will need "munpack" or
a MIME-compliant mail reader. Different MIME-compliant mail readers
exhibit different behavior, especially when dealing with
"multipart" MIME messages (i.e. documents which have been split
up into multiple messages), so check your local documentation on
how to manipulate these messages.
Below is the data which will enable a MIME compliant mail reader
