Embodiment Construction

[0023] According to the multi-protocol label switching (MPLS) / traffic engineering (TE) tunnel network bandwidth resource allocation scheme of the present invention, it mainly involves the following modules and messages: NMS / OAM (network management system / operation and maintenance system), tunnel head node, tunnel node , signaling, tunnel strict / loose path nodes, RACF / RACS; and also involves: tunnel bandwidth, quality of service parameters.

[0024] In this embodiment, a method for allocating MPLS / TE tunnel resources is provided, figure 2 It is a schematic diagram of a method for allocating MPLS / TE tunnel resources according to an embodiment of the present invention.

[0025] Such as figure 2 As shown, the allocation methods of MPLS / TE tunnel resources include:

[0026] Step S202, establishing a tunnel (that is, an MPLS / TE tunnel), and allocating resources to the tunnel;

[0027] Step S204, RACF / RACS responds to the service session request, and allocates available bandwidt...

Abstract

The invention discloses a distribution method for multi-protocol label switching / traffic engineering tunnel resource which comprises the steps that: after the establishment of a tunnel, a resource admission control function entity or a resource admission control subsystem responses to a service dialogue request and distributes available bandwidth recourses of the tunnel to the service dialogue requested by the service dialogue request; under the condition that the available bandwidth resources are insufficient to carry out the service dialogue requested, the resource admission control function entity or the resource admission control subsystem rejects the service dialogue. The technical proposal of the method of the invention determines the relationship among NMS / OAM and MPLS / TE tunnel establishment and RACF / RACS bandwidth resource distribution, thereby improving the efficiency of resource distribution.

Description

technical field [0001] The present invention relates to the communication field, and in particular, relates to a method for allocating multi-protocol label switching / traffic engineering tunnel resources. Background technique [0002] Currently, the International Telecommunication Union-Telecommunications standardization sector (ITU-T for short), the Telecommunications and Internet Convergel Services Protocols For Advanced Networking (TISPAN for short), the Internet engineering task Internet Engineering Task Force (IETF for short) and other international standard organizations are actively conducting research on next-generation networks and formulating standards. Among them, Multi-Protocol Label Switching / Traffic Engineering (Multi-Protocol Label Switching / Traffic Engineering, The MPLS / TE) technology is regarded as one of the core technologies of the next generation network (Next Generation Network, NGN for short) bearer network due to its features such as service quality man...
