Abstract: In a network processor-based device, there is provided a single routing table for network routers and an efficient routing algorithm implemented by the routing device. The routing table includes packet forwarding information including a subnet address associated with a destination address location, an ISO layer three (3) network protocol address, e.g., IP address, of a router interface that can route packets to the subnet address, and an identifier indicating whether that router is an exit BGP router that may or may not be directly attached to the packet forwarding router. A table look-up mechanism is provided to determine next hop information and determine associated BGP status of the next hop. At such time it is determined that a router is not a BGP router (i.e., is directly attached to the forwarding router), the packet will be transmitted to that router.

A network element device is added as a managed object to the network by the collection of information is stored in a managed-object instance corresponding to the network element device.

Abstract: Systems and methods are disclosed for switching servers in a network computer system comprising a plurality of servers each of which has a corresponding actual address, and all having an imaginary address in common. According to the disclosed systems and methods, a packet containing a network trailer addressed to an imaginary network address is transmitted to a gateway. The gateway generates a new packet containing the network trailer, addresses the new packet with an actual IP address of one of a plurality of servers according to states of the system, and then transmits the new packet to the server. The server periodically informs the gateway of a state of its own imaginary network address, and the gateway updates its own IP address correspondence table. For remote servers interconnected via a WAN environment, service may be provided to a client by one remote server taking over the service provided by another in the same manner as if the server were adjacent to each other.

The redirector station is arranged to select an optimum server (74) to handle communications of a user device on the basis of both the physical location of that server relative to the user device and its current communications traffic loading and, having made its selection, it instructs the user device to re-establish network communications via the selected server.

Abstract: A method and system is provided for delaying the loading of classes that are unnecessary the start-up of an applet when a server sends an applet to a client. Methods and systems consistent with the present invention package the class files necessary for start-up of the applet on the client in a single archive file along with relatively small interface classes that reference the delayed classes This archive file, being smaller, saves download time and can be sent with a single connection from the server computer to the client computer, as opposed to multiple connections. These methods and systems consistent with the present invention also provide a way for the client computer to request the delayed classes not included in the initial archive file if the delayed class is later needed by the client computer.

Abstract: Throughput of a request (e.g., a write request) is enhanced by allowing a receiver of the request to reply to the request before fully receiving the entire request. This reduces the delay between the time that the receiver completes a request and the time that the sender sees that the request is finished, and allows other requests to be forwarded prior to completion of the first request. The other requests that are forwarded, however, are processed in the order of receipt. Additionally, any errors that occur in a request after the reply is sent is forwarded to the sender of the request, even though the reply has previously been sent.
