Embodiment Construction

[0017] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0018] The key point of the present invention is that the label type TLV carried in the label request message of the LDP indicates to the upstream what type of label needs to be distributed, which will be described in detail below focusing on this.

[0019] figure 1 is a flow chart of a label distribution method for notifying upstream distribution labels in a label distribution protocol according to the present invention. figure 2 is a view of the format of a tag type TLV according to an embodiment of the present invention.

[0020] The following will refer to figure 2 , described as figure 1 Shown is a label distribution method for notifying upstream to distri...

Abstract

The invention provides a label distribution method used in a label distribution protocol for informing an upstream LSR to distribute labels. The method comprises the following steps of: a step S102, in which a certain label TLV type is carried on a label request message and sent by a downstream LSR to the upstream LSR; and a step S104, in which the upstream LSR receives the label request message carrying a certain label TLV type and analyzes the certain label TLV type and distributes a label of the corresponding type for the FEC in accordance with the field valve of the certain label TLV type. Therefore, an upstream LSR serving as the penultimate hop of a certain FEC can, under upstream label distribution mode, send an implicit-null label as an output label, thereby realizing the penultimate hop popping.

Description

technical field [0001] The present invention relates to a label distribution protocol (Label Distribute Protocol, hereinafter referred to as LDP) technology in a multi-protocol label switching (Multi Protocol Label Switch, hereinafter referred to as MPLS) network, and more specifically, relates to a label distribution protocol used in Notifies the upstream of the tag distribution method for distributing tags. Background technique [0002] Usually, at the last hop of a label switching path (Label Switch Path, hereinafter referred to as LSP), the label switching router (Label Switch Router, hereinafter referred to as LSR) will give the corresponding forwarding equivalence class (Forwading Equivalence Class, hereinafter referred to as For FEC) bind an empty label as an incoming label (either implicitly empty or explicitly empty). [0003] The purpose of allocating implicit null is to use this label to tell the LSR of the last hop that when receiving the label message sent to t...
