Abstract: A primary ARP server and a backup ARP server are connected to an ATM communications network. The primary and backup ARP servers each have associated ATM addresses. Also, a LIS is connected to the ATM communications network. Either the primary or backup ARP server is the active ARP server and resolves IP addresses to ATM addresses for the LIS. When the backup ARP server recognizes the removal of a redundancy virtual channel connection (VCC) between the backup ARP server and the primary ARP server, the backup ARP server registers using the ATM address associated with the primary ARP server. This allows the backup ARP server to take over for the primary ARP server to become the active ARP server.In addition, a primary default gateway and a backup default gateway are connected to the ATM communications network. These default gateways have associated ATM addresses. One of the primary and backup default gateways is active at a time.

Abstract: method of matching computer wild card patterns involves comparing first and second character strings associated with named objects residing on a computer system to determine whether the first character string defines a first group of computer objects which is a logical subset of a second group of computer objects defined by the second character string. The first character string is provided by a user; such as in a command line, and the second character string is pre-defined, such as by a network administrator. The method can be performed by examining whether the second character string has any wild card character which can substitute for one and only one character, or by examining whether the second character string has any wild card character which can substitute for any number of characters, including no characters (a universal character). The second character string can further be examined to see if it contains any embedded sequence of characters having no universal wild card character.

Abstract: To ensure a LES issues address resolution responses when necessary, an association between a MAC/ATM address pair and an intersubnet shortcut virtual channel connection (VCC) is registered. When the LES receives a first data frame being sent from a first station to a second station, with the second station having a MAC address associated with a shortcut VCC, a second data frame is created. The second data frame has as a source address the MAC address. The second frame is sent to devices associated with the first station so that the devices may learn the origination point for the second station and can issue messaging necessary to establish an shortcut VCC. In addition, frame loss reduction in an ATM communications network is accomplished by registering an association between a MAC address of a router associated with a MAC/ATM address pair, and a shortcut VCC. After the association is registered, a data frame being sent from a first station to a second station is received.

Abstract: A sequence in which two or more of the data units enter the network node, via a specific one of the multiple ports, is recorded. And, the two or more of the data units are transmitted from the network node according to the recorded sequence. The method and system achieve the recording of sequence via the following. In response to an insertion of one of the two or more data units into a specific one of the multiple processor subsystems, the specific one of the multiple processor subsystems is associated with a specific one of the multiple ports by which the one of the two or more data units entered the network node, and any other of the multiple processor subsystems that are currently processing on any other of the two or more data units that entered the network node through the specific one of the multiple ports is noted.

Abstract: A method of selectively obtaining formatted dump data from a remote software product employs an open Manager-Agent concept, where the Agent is represented by the remote software product and the Manager is represented by the local customer/vendor management station. A dump object is defined; this object exists at the Agent and is exposed to Manager for modification, e.g., specification of a value. Modification of the dump object by the Manager will cause the Agent to selectively create/store a formatted storage dump for one or more of software products components. The Manager retrieves the formatted dump data from the Agent using a standard/open file transfer mechanism; since the dump data is formatted at the Agent (rather than by the receiver, i.e., manager) the problem of transmitting large amounts of data across a network is minimized or eliminated.
