Metro Ethernet

Conclusion

This chapter has discussed the basics of RSVP-TE and how it can be applied to establish LSPs, bandwidth allocation, and fast-reroute techniques. A detailed explanation of the RSVP-TE messages and objects was offered to give you a better feel for this complex protocol, which probably requires a book of its own. Many of the techniques explained in this chapter apply to provisioning scalable L2 metro Ethernet services.

The metro will consist of a mix of technologies ranging from Ethernet switches to SONET/SDH equipment to optical switches. Creating a unified control plane that is capable of provisioning LSP tunnels end to end and helping in the configuration and management of such equipment becomes crucial. You have seen the MPLS control ...
