Connected to different routers of a packet routing network through a public network and to local area networks (LAN's) and comprising a routing table keeping routing information for an optimum path between each pair of the LAN's, a local router comprises a protocol processor for periodically processing the routing information into a local routing information protocol (RIP) datum indicative of connection information to the LAN's connected to the local router and a comparator comparing the local RIP datum with stored information of an RIP memory to discard and to write in the memory as a current datum the local RIP datum if the local RIP datum is coincident and incoincident with the stored information, respectively. A public network interface sends the current datum towards the different routers. In the routing table, the routing information is dynamically updated in response to an incoming RIP datum received from any one of the different routers.
A packet routing method used in each router of a plurality of routers in a packet routing network, each router operating as a local router for transmitting packets to and receiving packets from at least a respective one of a plurality of local area networks and operating to dynamically route packets to and from other routers of said packet routing network via public network, comprising the steps of:
A packet routing network comprising a plurality of routers, each of said routers operating as a local router for transmitting packets to and receiving packets from at least a respective one of a plurality of local area networks and operating to dynamically route packets to and from others of said routers via a public network;
A router operating as a local router in a packet network for transmitting packets to and receiving packets from at least a respective one of the plurality of local area networks and operating to dynamically route packets to and from other routers in said packets network via a public network;
A packet routing network comprising a plurality of routers, each of said routers operating as a local router for transmitting packets to and receiving packets from at least a respective one of a plurality of local area networks and operating to dynamically route packets to and from others of said routers via said public network, each of said routers comprising:
A router operating as a local router in a packet network for transmitting packets to and receiving packets from at least a respective one of a plurality of local area networks and operating to dynamically route packets to and from other routers in said packet network via a public network, said router comprising:
