Internet traffic engineering is defined as that aspect of
Internet network
engineering dealing with the issue of performance evaluation and performance optimization of operational
IP networks
The Internet protocol suite, commonly known as TCP/IP, is a framework for organizing the set of communication protocols used in the Internet and similar computer networks according to functional criteria. The foundational protocols in the sui ...
. Traffic engineering encompasses the application of technology and scientific principles to the measurement, characterization, modeling, and control of Internet traffic

Enhancing the performance of an operational
network, at both traffic and resource levels, are major objectives of Internet engineering. This is accomplished by addressing traffic performance requirements, while utilizing network economically and reliably. Traffic oriented performance includes
packet transfer delay
Packet may refer to:
* A small container or pouch
** Packet (container), a small single use container
** Cigarette packet
** Sugar packet
* Network packet, a formatted unit of data carried by a packet-mode computer network
* Packet radio, a form ...
,
packet delay variation,
packet loss, and
throughput.
An important objective of Internet traffic engineering is to facilitate reliable network operations
FC-2702 This can be done by providing mechanisms that network integrity and by embracing policies emphasizing survivability. This results in a minimization of the network to service outages arising from errors, faults and failures occurring within the infrastructure.
The Internet exists in order to transfer information from nodes to
destination node
Destination may refer to:
Music
*Destination (group), a disco studio group from New York
* ''Destination'' (Eloy album), 1992
* ''Destination'' (FictionJunction Yuuka album), 2005
* ''Destination'' (Ronan Keating album), 2002
* ''Destination'' (EP ...
s. Accordingly, one of the most crucial functions performed by the Internet is the routing of traffic
ingress node
Ingress may refer to:
Science and technology
* Ingress (signal leakage), the passage of an outside signal into a coaxial cable
* Ingress filtering, a computer network packet filtering technique
* Ingress protection rating, a protection level t ...

egress nodes.
Ultimately, it is the performance of the network as seen by network services that is truly paramount. This crucial function should be considered throughout the development of engineering mechanisms and policies. The characteristics visible to end users are the emergent properties of the network, which are characteristics of the network when viewed as a whole. A goal of the service provider, therefore, is to enhance the properties of the network while taking economic considerations into account.
The importance of the above observation regarding the properties of networks is that special care must be taken when choosing network performance metrics to optimize. Optimizing the wrong metrics may achieve certain local objectives, but may have repercussions elsewhere.
