MPLS and Provider Network Trends
Options For Converged Networks with MPLS
- MPLS Integrates L2 switching and L3 routing on Label Switched Routers (LSRs)
- Signaling protocols are used for setting up Label Switched Paths (LSPs)
- Packets are forwarded by swapping labels at each hop
- An LSR can be either a traditional router or an FR or ATM switch with IP routing functionality
- Provides QOS and connection-oriented functionality to native IP network
- Adds IP flexibility to existing frame and ATM networks
