Embodiment Construction

[0025] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings. In the drawings, the same or similar components are denoted by the same reference numerals even if they are depicted in different drawings. In the following description, a detailed description of known functions and configurations incorporated herein will be omitted when it may obscure the subject matter of the present invention.

[0026] figure 1 is a structural diagram showing a multi-protocol label switching (MPLS) network to which the present invention is applied. MPLS systems typically use Internet Protocol (IP) / Asynchronous Transfer Mode (ATM) high-speed multi-service technology to quickly process existing Local Area Network (LAN) traffic and Internet traffic, and provide various additional services. The MPLS system is adapted to transport IP packets by adding the ATM high-speed multi-service switching function to the basic existing routing...

Abstract

A data structure for implementing a traffic engineering function in a multiprotocol label switching system comprises: a subscriber profile including a plurality of entries for storing forwarding equivalence class (FEC) information, the entries of the subscriber profile being sequentially assigned indexes corresponding to one traffic engineering service subscriber identification (ID); a path profile including a plurality of entries for storing respective path information items regarding a type length value (TLV) of a signal protocol, the entries of the path profile being sequentially assigned indexes corresponding to respective path information items; and a quality of service (QoS) profile including a plurality of entries for storing respective QoS information items regarding a TLV of a signal protocol, the entries of the QoS profile being sequentially assigned indexes corresponding to respective QoS information items. The indexes assigned to the profile entries include a plurality of indexes set by an operator for interlinking corresponding ones of the subscriber profile entries, the path profile entries, and the QoS profile entries.

Description

technical field [0001] The present invention generally relates to traffic engineering for a multiprotocol label switching (MPLS) system, and more particularly, to a data structure for implementing traffic engineering and a storage medium for storing the data structure. Background technique [0002] Since the early 1990s, there has been a constant need for improved quality of service and reliability of Internet networks as Internet access requirements have increased rapidly, making them move away from traditional key network attributes of large scale (or high speed) and best-effort out of the supply of services. Recently, Internet Service Providers (ISPs) have paid special attention to Quality of Service (QoS) since the Internet has been used as an infrastructure for economic activities. In accordance with this trend, ISPs have adopted the MPLS (MPOA) system of ATM using the Asynchronous Transfer Mode (ATM) network, or added more than necessary resource...
