MPLS (Multiprotocol Label Switching) is a protocol used in telecommunications networks to improve the speed and efficiency of data transmission.

• MPLS is a technique that uses labels to forward network packets instead of traditional IP routing.

• It allows for faster packet forwarding by using pre-determined paths and avoiding complex lookups.

• MPLS can be used to prioritize traffic, ensuring better quality of service for critical applications.

• It enables the creation of virtual priv...read more

MPLS (Multiprotocol Label Switching) typically uses port 646 for LDP (Label Distribution Protocol) communications.

• MPLS primarily operates over IP networks, using port 646 for LDP.

• LDP is essential for establishing label-switched paths (LSPs) in MPLS.

• Other protocols like RSVP-TE may use port 102 for signaling in MPLS networks.

• MPLS can also work with various transport protocols, but port 646 is standard for LDP.
