摘要： Packet switch operating methods and packet switches receive, at a packet switch, a control packet from another packet switch. The packet switch and the other packet switch are coupled together by two or more tunnels. The control packet indicates that a particular one of the tunnels is active on the other packet switch. In response, the packet switch operating methods and packet switches activate the particular tunnel indicated by the received control packet on the packet switch.

摘要： Element managers and processes receive, from a selected network element, first neighbor information describing a first neighboring network element directly connected to the selected network element and second neighbor information describing a different second neighboring network element directly connected to the selected network element. Based at least in part on the first neighbor information and the second neighbor information, the element managers and processes determine that the first neighboring network element is a logical neighbor that is connected by a tunnel to the selected network element and is coupled to the selected network element via one or more intermediate packet switches.

摘要： Element managers and processes retrieve information from a first packet switch. The information is derived from layer-two (data link layer) control packets relayed from a second packet switch to the first packet switch via a tunnel. The layer-two control packets conform to a layer-two control protocol. Based at least in part on the retrieved information, the element managers and processes determine that the tunnel is configured to relay layer-two control packets conforming to the layer-two control protocol despite a desired tunnel configuration specifying that the tunnel should not be configured to relay layer-two control packets conforming to the layer-two control protocol. Element managers and processes may alternatively or additionally detect other discrepancies between the desired tunnel configuration and the tunnel.

摘要： This document describes tools that communicate an operational state of a transport service. The transport service provides connectivity between two or more networks, enabling the networks to exchange packets. The tools detect an operational state of a transport service. After doing so, the tools may convey the operational state of the transport service to at least one of the networks through a user-to-network interface port of a network interface device, send a message to a network interface device requesting that the network interface device convey the operational state to a network connected to the network interface device, or configure a network interface device to communicate the operational state.
