Using conventional IP routing, traffic engineering cannot be implemented because all forwarding at Router A is based on the packet's destination address If core routers function as LSRs and LSP 1 and LSP 2 are configured as path 1 and path 2, MPLS provides ISPs an unprecedented level of control ...

Consensus in a Box: Inexpensive Coordination in Hardware

In this paper we tackle the four challenges discussed above: We implement a consensus protocol in hardware in order to remove the enforcement of consistency from the critical path of performance without adding more bulk to the data center. We create a reusable solution that can augment ...
