Metro Ethernet

Conclusion

This chapter has discussed the different parameters used for TE. Some of the concepts, such as traffic parameter attributes and policing attributes, were discussed in the context of metro deployments in Chapter 3.

The next steps for TE entail a mechanism for exchanging the traffic attributes and parameters in the network for each router to build a TE database. This database gives the routers visibility to all the network resources and attributes that can be used as input into a Constrained Shortest Path First (CSPF) algorithm. CSPF determines the path in the network based on different constraints and attributes. Finally, a signaling protocol such as RSVP-TE is used to signal the LSP in the network based on the path determined by the ...
