LDP IGP synchronization for broadcast networks
A method and apparatus for LDP-IGP synchronization for broadcast networks. In one embodiment of the invention, responsive to a network element bringing up an adjacency with a Designated Router of the broadcast network on a broadcast interface, that network element advertises in its Link State Advertisement (LSA) a peer-to-peer (P2P) adjacency to each member of the broadcast network that has bidirectional IGP communication with the network element instead of advertising a pseudo-node adjacency to the pseudo-node of the broadcast network. Each P2P adjacency includes a high cost to discourage use of those links for transit traffic. After LDP becomes operational with all neighbors on the broadcast interface, the network element advertises the pseudo-node adjacency instead of the P2P adjacencies. Accordingly, transit traffic is avoided through that network element until LDP is operational with all neighbors on the broadcast interface. |

A copper interconnect structure has an intrinsic graphene cap for improving back end of line (BEOL) reliability of the interconnect by reducing time-dependent dielectric breakdown (TDDB) failure and providing resistance to electromigration.

The reduction of TDDB failure and improved resistance to electromigration improves BEOL reliability of the copper interconnect structure. |
