This document updates TIA-1039 protocol which provides a Quality
\nof Service (QoS) signaling standard for use within IPv4 and IPv6
\nnetwork-layer protocols. It also adds a security capability which
\nallows authentication of the sender to greatly increase the network
\nsecurity. The TIA-1039A signaling scheme is designed to work
\n"in-band", and requires hardware or microcode support in the
\nparticipating network elements. To accomplish this, the QoS is
\nsetup in real time across the network without a separate, outof-
\nband, software signaling structure like Reservation Protocol
\n(RSVP). The resource "request" and the "response" messages for TCP
\nare incorporated into the initial packets in the actual data flow,
\nallowing the QoS requirements to be setup in parallel with the
\ninitial network traversal from sender to receiver and back. This
\nsignaling scheme can be used to set the rate, burst tolerance,
\npreference priority, and delay priority.<\/p>\n
TIA-1039 was introduced into the ITU many years ago and is now
\nprogressing as Q.Flowstatesig. However, the marking of signaling
\npackets with a DCSP code has been rejected as creating a potential
\nincompatibility with other IP systems. In order to avoid any impact
\non current IP practices, the revised approach is to encapsulate all
\npackets with a GRE protocol packet header using a IEEE assigned
\nEthertype code, making the TIA-1039A traffic all appear as a new
\nprotocol. An Ethertype code (0x22EF) has been obtained for the
\nrevised protocol. As all the packets are now unique to this
\nprotocol, signaling can easily be marked with no conflict with
\nother IP traffic. Also, since TIA-1039 has been extensively tested
\nunder two DARPA programs, there are other simplifications and some
\nchanges to avoid possible error conditions. Lastly, this version
\nhas a new addition; the addition of a security structure to allow
\nsecure authentication of the sender. The network uses this to
\nobtain the current maximum priority allocated to the sender, and
\nthe receiver may also obtain certain limited information about the
\nsender. This addition allows the new protocol to be safely used for
\nEmergency Services to give priority to designated personal during
\nan Emergency. It also is designed to support a wide priority range
\nfor use in a military network. It is designed to provide a new,
\nmuch higher level of network security where it is used.<\/p>\n
The QoS defined within this signaling structure can support four
\ngeneral types of service. The first is a fully guaranteed rate
\nservice flow, which implies no oversubscription of network
\nresources. The second is a maximum rate service flow, which allows
\nsome oversubscription but virtually no packet loss. The third is a
\nvariable rate service flow, where available rate is combined with a
\nminimum rate guarantee. The fourth is an available rate service
\nflow, one that can jumpstart the Transmission Control Protocol
\n(TCP) to the highest rate the network can support, eliminating
\nslow-start problems. In the available rate service case the
\ncapacity available based on network congestion is fed back to the
\nsender very rapidly at all times. This will help to differentiate
\ncongestion problems from channel errors (measured in bit error
\nrates), permitting the sender to then optimize his packet error
\ncontrol without confusing it with congestion. For premium services
\nlike voice and video maximum rate service sets up a low delay, low
\nloss path with a minimal of effort.<\/p>\n
This version of TIA-1039A adds a new capability to improve
\nnetwork security through session authentication. Security against
\ncyber crime has thus far been mainly focused on the computer but
\nthis battle is being lost; more software holes are found each month
\nthan can be patched. This goal of this new capability is to have
\nthe network help in this battle by authenticating the user and the
\ncomputers attached. The session authentication is optional and the
\nattributes of ones identity which are provided to the network or
\nthe receiver are under the sender's control. However, legal
\ninvestigation of a cyber crime may have access to the user's
\nidentity and transaction history, thus allowing, finally, the
\nability to track down and stop most all cyber crime.<\/p>\n","protected":false},"excerpt":{"rendered":"
