what is mpls circuit

. MPLS uses Label Switching. The network router only needs to identify the label before forwarding.The principle of MPLS operation is to provide a tag for each IP packet, and thus determine the path and priority of the packet. A Router compatible with MPLS reads only the packet mark before it forwards data packets to i

Group First, let's look at the concept of the next grouping. The so-called grouping is to divide a packet into smaller packets. For example, for a 10GB packet, it is not always a one-time delivery of the past bar, but it is divided into a number of small packets sent past. Structure diagram for each block of data:File headers are typically descriptive data, such
