Chapter 1, Traffic Engineering Overview, provides a functional description of the four major components of traffic engineering, as well as the various methods of calculating and configuring label-switched paths LSPs.!
A VPN applicafions an extension of a private network that uses. About This Manual xix. This chapter discusses the following topics: Packet Forwarding Based on Label Swapping The packet forwarding process at each router is based on the concept of label swapping.
Administrative attributes required to coniguration traffic traversing the proposed LSP such as bandwidth requirements, maximum hop count, and administrative policy requirements that are obtained from user configuration As CSPF considers each candidate node and link for a new LSP, it either accepts or rejects a specific path component based on resource availability or whether selecting the component violates user policy constraints.

Munos product includes memory allocation software developed by Mark Moraes, copyright,University of Toronto. This information is provided in the text of the statement application. All specifications are subject to change without notice.
Online calculation takes resource constraints into account and calculates one LSP at a time. Meanwhile, the IGP continues its operation without modification, performing the traditional shortest-path calculation based on information contained in the router s link-state database.
Once the packet begins to traverse the LSP, each router uses the label to make the forwarding decision. The explanation of each configuration statement consists of the following parts:! Installation and System Management.!
Each part describes a major functional area of the JUNOS software, and the individual chapters within a part describe the software components of that functional area.

If the order in which the LSPs are calculated is changed, the resulting set of physical paths for the LSPs also can change.

LSPs that are calculated early in the process have more resources available to them than LSPs calculated later in the process because previously calculated LSPs consume network resources.
