Connection-oriented services for packet switched data communications networks are provided, including distributed MAC and protocol alias addresses discovery. Link state topology exchanges provide each switch with network topology graphs to determine paths from source to destination end systems. Broadcast frames are resolved to unicast frames to reduce broadcast traffic. Policy restrictions may be applied prior to connection setup. Connection management includes source-routed mapping of connections on the desired path. Distributed call rerouting is provided so switches receive topology change notifications and unmap failed link connections. Broadcast/unknown services provide non-resolvable packet restricted flooding. Connection-oriented switching is provided based on source and destination MAC addresses. Resolution of networks outside the switch domain is enabled by listening for network and server route advertisements and maintaining best routes to the networks and servers. Route and path metrics may be combined to determine paths from access switches to egress switches connected to the external network.
