Embodiment Construction

[0033] The technical solutions of the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0034] The basic concept of the present invention is: in order to overcome existing MPLS forwarding, in the processing flow of data packet, need to look up the defect of forwarding efficiency multiple times in the process of data packet, after receiving the data packet that is encapsulated with described incoming label, There is no need to repeat the multiple table lookup operations of the existing data packet processing flow, but directly obtain the pre-saved data corresponding to the incoming tag through a single search, and perform the processing according to the incoming tag of the data packet according to the existing data packet processing flow. The encapsulation information obtained by multiple table lookups and business processing is replaced by the encapsulation information of the data packet before forwardin...

Abstract

The invention discloses a multi-protocol label switching forwarding method, comprising: after receiving a data packet, searching for pre-saved encapsulation information corresponding to the incoming label according to the incoming label encapsulated by the data packet, and converting the data The encapsulation of the packet is replaced with the encapsulation information and then the data packet is forwarded. The invention also discloses a multi-protocol label switching forwarding device, which includes a data packet receiving module, a data packet processing module connected to the data packet receiving module, a data packet sending module connected to the data packet processing module, and a fast forwarding module, Connect with the data packet receiving module and the data packet sending module. The invention can effectively reduce the times of table lookup in the multi-protocol label switching forwarding process, and improve the forwarding efficiency of the multi-protocol label switching forwarding device.

Description

technical field [0001] The invention relates to a forwarding method and forwarding equipment in the communication field, in particular to a multi-protocol label switching forwarding method and forwarding equipment. Background technique [0002] Multi-Protocol Label Switching (MPLS for short) is a packet switching technology based on the label mechanism, which belongs to the third-generation network architecture and is a new generation IP high-speed backbone network switching standard. MPLS technology uses short and fixed-length labels to encapsulate network layer packets, and implements packet forwarding by switching labels at each node. Inside the MPLS network, the forwarding is realized by exchanging labels in the forwarding devices along the path of the data packet (rather than by checking the IP packet header); when the data packet is about to leave the MPLS network, it is unencapsulated by the label and continues to follow the IP routing method reach the destination. ...
