Technology: MPLS Home
MultiProtocol Label Switching architecture provides a unified data-carrying
service/simple routing for both circuit-based clients and packet-switching clients
providing a datagram service model.
• It allows voice, IP, ATM, Frame Relay and Ethernet services all to be carried
on the same network.
• It can be used with many types of framing, including Ethernet.
• The Layer 3 label analysis is only just once, when the packet enters the MPLS
domain. After that, labels are just inspected to continue packet forwarding.
MPLS Structure
The MPLS header contains a 'stack’ of one or more labels. A label has four fields:
• 20-bit label value
• 3-bit field for CoS priority (experimental)
• 1-bit bottom of stack flag. If used, it signifies the current label is the last in
the stack
• 8-bit TTL (time to live) field; The Time to Live label will expire at the
conclusion of this number of time-to-live hops.
• The Experimental field can be used to distinguish classes of service, or per
hop behavior, for differing classes of traffic traveling within the MPLS tunnel
(AKA Label Switched Path - LSP). Alternatively, an LSP carrying a single traffic
class uses the label to determine the per hop behavior of the class.
