摘要： A method and system for improving communications in data communications networks which provide network emulation. The method and system accomplish their objects via communications equipment adapted to do the following: implant a number of distributed-redundant gateways in an emulated network; and dynamically assign access to operational distributed-redundant gateways. In one embodiment, the network emulation is an Asynchronous Transfer Mode Emulation Local Area Network (ATM ELAN), and the distributed-redundant gateways operate as default Internet Protocol (IP) gateway utilized by LAN Emulation Clients (LE Clients) of the ATM ELAN. Also in one embodiment, the dynamic assignment of access is done such that the data communications loading associated with the default IP gateway is distributed throughout a data communications network.

摘要： An ATM communications network with several ELANs allows steady-state data to be passed between ATM attached devices which bypasses intermediate LECs and bridges. Connected to the ATM communications network is a bridge unit which includes a bridge and associated LECs. Also, an origination ATM attached device and a destination ATM attached device are attached to the ATM communications network via a first by a first ELAN and a second ELAN, respectively. The origination ATM attached device sends a request for an ATM address associated with the destination ATM attached device to the bridge, via the first ELAN. After some processing, the bridge returns the ATM address associated with the destination ATM attached device to the origination ATM attached device. This allows the origination ATM attached device to establish a shortcut VCC with the destination ATM attached device using the ATM address associated with the destination ATM attached device, thereby bypassing intermediate bridges and LECs.

摘要： Mechanism for use in an internetworking device incorporating a translational bridging function to provide load balancing across multiple instances of the same destination address. Traffic originating with clients in the transparently bridged domain is distributed over multiple communication paths to the multiple instances of the destination address in the source route bridging domain. The internetworking device sends an explorer frame over each interface in the source route bridging domain to discover all parallel paths to the destination address. The internetworking device receives a response from each instance of the destination address over all possible paths. The routing information contained in the responses is used to create entries in a cache in the internetworking device. Load balancing is performed by using the source address of the transparently bridged clients as a key to select a specific path for each such client. Frames originating with different clients in the transparent bridging domain are then distributed over the selected paths to the same destination address.

摘要： A large flat IP network is created in a switched layer-2 network by adjusting the subnet masks of hosts such that these hosts can communicate directly with other hosts without the use of an intermediate router. The layer-2 switches are configured with user-selected IP subnets and monitor and analyze multicast packets to learn the mapping between IP subnets and switch ports. The layer-2 switches selectively forward the mulitcast packets based on the learned mappings between IP subnets and ports. After the destination host responds to the forwarded multicast, a direct connection is established between the source and destination hosts using the media access control addresses of both hosts.

摘要： A method for automatically generating a network subnet configuration, monitors IP Address Resolution Protocol (ARP) frames on the network and builds and maintains a table which includes a list of learned subnets, the ports or forwarding domain associated with each of the learned subnets and a mask associated with each learned subnet for identifying hosts belonging to the subnet. The from and to IP addresses from intercepted IP ARP frames are examined to determine if the IP addresses belong in any of the learned subnets. If neither IP address belongs to an existing learned subnet a new learned subnet is established. The subnet includes the common prefix bits of both IP addresses, a mask identifying those bits and the port over which the ARP frame was received. If only one IP address belong to a learned subnet, the mask associated with that subnet is modified to include the common prefix bits of both IP addresses and the forwarding domain is adjusted. If the two IP addresses belong to different learned subnets, the two subnets are combined.
