Abstract
A router for routing data redundantly relative to a network. The router includes a circuit card having a processor, a user port for connecting at least one user device with the processor, and a plurality of interface ports for redundantly connecting the processor with the network to provide active redundant communication with the user device(s). This router can have a small form factor, can be ruggedized, and can provide fast redundant routing through redundant network backbones.
Claims6
A method of routing data between a user device and a network, the method comprising:
- connecting with the user device through a user interface of a circuit card of a router;
- through a plurality of backbone interfaces of the circuit card, connecting with the network through a plurality of separate packet-switched backbone subnets to provide redundant communication of data frames through a virtual subnet that includes the backbone subnets;
- receiving a packet from the user device through the user interface;
- encapsulating the received packet in a plurality of redundant data frames in accordance with a redundancy protocol for transmission of the frames through the backbone interfaces and the backbone subnets;
- and
- transmitting the encapsulated packet redundantly to the network;
- the method performed by the router.
