Abstract

The invention discloses a label processing method and a device employing the same, relates to the technical field of communication network and aims to solve a technical problem that quantity of MPLS (Multiple Protocol Label Switching) labels in the prior art cannot support network development. The label processing method includes steps that a first network device distributes first labels generated according to first cardinal number labels and remainder labels for the FEC (Forwarding Equivalence Class), wherein an actual label value corresponding to the first cardinal number labels is larger than or equal to 1 mega; the first network device transmits a label notification message to a second network device, wherein the label notification message includes the first cardinal number labels and the remainder labels and is used for the second network device to generate the first labels according to the first cardinal labels and the remainder labels and to establish a corresponding relation of the FEC and the first labels. By adopting the technical scheme provided by the invention, the quantity of the MPLS labels can be increased effectively, so that the development of MPLS technology is facilitated.

Description

technical field [0001] The present invention relates to the technical field of communication networks, in particular to a label processing method and device. Background technique [0002] A Multi-Protocol Label Switching (MPLS) label is a short identifier with a fixed length and only local meaning, which is used to uniquely identify the Forwarding Equivalence Class (FEC) to which a packet belongs. The MPLS label occupies 20 bits, that is, the label has a maximum of 2 20 indivual. The label space of MPLS can be divided into three sections. The first section is a special label, and the label range of the special label is 0 to 15; the second section is a reserved label, and the label range of the reserved label is 16 to 1023; the third section is a dynamic label, and the label of the dynamic label range from 1024 to 2 20 -1. With the widespread use of MPLS labels, the number of MPLS labels cannot meet the needs of network development. [0003] In the prior art, a multi-in...
