Abstract:

One embodiment of the present invention provides a system that identifies network switches along a path. During operation, the system receives an address of a source node and an address of a destination node. The system maintains a set of topology information for a network. The system further simulates a data packet originated at the source node and destined for the destination node. During the simulation, the system determines whether a current-hop node performs layer-3, layer-2, or sub-layer-2 switching. The system sends a query to the current-hop node over a separate control channel to determine the status of the current-hop node and discover a next-hop node. The system then receives a reply. The system determines the next-hop node based on the reply and sets the next-hop node as the current-hop node.

Abstract:

Content stored on a server may be selected using a user device and enabled on a central device. The identity of the central device may be authenticated without transmitting user credentials corresponding to the user, user device, user account, etc. A central device identifier can be sent to the server via the user device. An encrypted version of the central device identifier may be returned to the user device and to the central device. The central device can send the encrypted and unencrypted version of the identifier to the server, and the server can transmit the desired content to the remote device based on a comparison of the encrypted and unencrypted identifier.
