Abstract: Techniques for automated configuration are provided. A first device detects a new device connected by one or more new links in a network, and the first device transmits, to a dynamic host configuration protocol (DHCP) server, a request for a first new subnet. The first device then assigns a first address of the first new subnet to a first new interface of the first device. The first device additionally transmits a second address of the first new subnet to the new device, where the new device uses the second address to establish connectivity to the network.

Abstract: Services with policy control may be provided. A computing device may receive registration information associated with a border device. The registration information may comprise information identifying a service provided by a server associated with the border device, information identifying the border device, and policies associated with the service. Then an address for the server may be determined. Next a request may be received comprising the information identifying the service provided by the server. In response to receiving the request comprising the information identifying the service provided by the server, the address for the server, the information identifying the border device, and the policies associated with the service may be provided.

Abstract: In one embodiment, network node-to-node connectivity verification is performed in a network including data path processing of packets within a packet switching device. In one embodiment, an echo request connectivity test packet, emulating an echo request connectivity test packet received from a first connected network node, is inserted by the packet switching device prior in its data processing path prior to ingress processing performed for packets received from the first connected network node. A correspondingly received echo reply connectivity test packet is intercepted by the packet switching device during data path egress processing performed for packets to be forwarded to the first connected network node.

Abstract: A traffic flow based map cache refresh may be provided. A computing device may receive a dropped packet message when a packet associated with a flow having a destination and a source was dropped before it reached the destination. Next, in response to receiving the dropped packet message, a map request message may be sent to a Map Server (MS). In response to sending the map request message, a map response message may be received indicating an updated destination for the flow. A map cache may then be refreshed for the source of the flow based on the updated destination from the received map response message.
