Abstract
Official abstract text for this publication.
An apparatus and method for processing a packet in a multi-protocol label switching-transport profile (MPLS-TP) network are provided. In the method of processing a packet, a packet transport layer (PTL) index and a layer stack (LS) or multiple label pop (MPOP) loopback header are used, and it is possible to remove a size limitation on lookup results of a lookup table when multiple labels are stacked, and solve the problem of having to extract all labels as label keys regardless of label operations upon an incoming label map (ILM) table lookup.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of processing a packet in a multi-protocol label switching-transport profile (MPLS-TP) network, comprising: classifying an input packet, and extracting or generating at least a packet transport layer (PTL) index through a lookup according to the classification result; performing a lookup for determining a next hop using the extracted or generated PTL index, and acquiring service-specific lookup results; checking whether the input packet is a mu…
