Multiprotocol Packet Label Switching, or MPLS, uses a fixed-path approach to routing packets across a network. The first router to encounter a packet attaches a label to the packet that corresponds to a fixed path to the final destination. Other routers along the way then simply read the label on the packet and use that label to determine where the packet should go next, without performing any lookups. In this video, learn how MPLS networks function.
- [Instructor] MPLS provides an efficient way…to route traffic along fixed network paths.…The vast majority of networks use IP address-based routing…to send packets on their way by looking…at the destination IP address and comparing…it to internal routing tables at each hop along…the way, seeking the best possible route…to the final destination.…This approach can be time consuming…for the routers involved.…At each step, the router must verify…the final destination IP address, look…that address up in routing tables,…and attempt to determine the best path…to the final destination.…
Packets between point A and point B…may wind up taking very different paths through the network.…Multiprotocol Packet Label Switching, MPLS,…uses a fixed path approach…to routing packets across a network.…The first MPLS router to encounter…a packet attaches a label to the packet…that corresponds to a fixed path…to the final destination.…Other routers along the way then simply…read the label on the packet and use…that label to determine where the packet should go next,…
