Title:
PACKET PROCESSING METHOD, APPARATUS AND SYSTEM
Document Type and Number:
WIPO Patent Application WO/2018/161672
Kind Code:
A1
Abstract:
Provided are a packet processing method, apparatus and system, decreasing a transmission time delay of each hop of physical device on a label switching path so as to reduce a packet transmission time delay. In the packet processing method, a first label switching router (LSR) receives a first multi-protocol label switching (MPLS) packet; the first LSR carries out fragmentation processing on the first MPLS packet to obtain a first MPLS fragmented packet; and the first LSR sends the first MPLS fragmented packet to a second LSR. The first MPLS fragmented packet comprises an MPLS label stack and a first MPLS fragmented packet header; the MPLS label stack comprises a first label set and a second label set, and the first MPLS fragmented packet header is encapsulated between the first label set and the second label set; a stack top label is a synonymous label, and a bit, in the synonymous label, representing a stack bottom identifier is set to be 1; and the first MPLS fragmented packet header comprises a fragmented packet sequence identifier.
