  • Low-latency data switching device and method
    Patent number: 10531168
    Abstract: Embodiments provides a low-latency data switching device and method. The device includes at least two boundary hardware modules and at least one optical forwarding module. The first boundary hardware module is configured for matching, with a first data forwarding table, signaling message information for a signaling message sent by a host router, acquiring a service request sent by the host router, and searching a second data forwarding table for an optical channel for the service request. The at least one optical forwarding module is configured for mapping the service request to a second service request, and forwarding the second service request in sequence via the optical channel, the second boundary hardware module is configured for acquiring next-hop routing information of the data switching device for the service request, and forwarding the service request to the next-hop router of the data switching device.
