MESSAGE MULTIPLE-TRANSFER METHOD, DEVICE AND SYSTEM

摘要

Disclosed in the embodiments of the invention are a message multiple-transfer method, device and system. The message multiple-transfer method comprises the following steps: receiving a message from a first slave equipment, wherein the message comprises a Multi-Protocol Label Switching(MPLS) header with multiple-transfer information,where the multiple-transfer information comprises a multiple-transfer identification field for indicating the slave equipment to which the message is to be transferred; determining a second slave equipment to which the message is to be transferred according to the multiple-transfer identification field; and transmitting the message to the second slave equipment. The multiple-transfer of the message among different network devices is realized by adopting that the multiple-transfer information is carried in the MPLS header. MPLS can carry more information than an existing Virtual Local Area Network (Vlan), and current standard protocols also can support at most 7 layers of MPLS headers, therefore, compared with the existing solution, this solution is more flexible, convenient and extensible, and more multiple-transfer information can be carried on the basis of meeting the current standard protocols.
