摘要： Controlling access to managed objects associated with a networked device. A method comprises receiving a request from a principal for access to a managed object associated with the networked device. The managed objects are accessible based on membership in access groups that are compliant with a Simple Network Management Protocol (SNMP). A first and a second of the access groups associated with the principal are determined. Access privileges for the principal are determined, based on the first and the second access groups. Access to the managed object is granted if permitted based on the access privileges for the principal.

摘要： A method is disclosed for Simple Network Management Protocol (SNMP) bulk information processing. A request for a plurality of object instances stored in a storage space is received. The request specifies a condition and a maximum number of repetitions. The values of one or more object instances of the plurality of object instances are retrieved. The retrieval of object instance values is terminated when the condition is satisfied even though the maximum number of repetitions is not reached. For example, the condition may be specified by one or more pairs of Object Identifier (OID) values, wherein each pair is represented by a starting OID value and an ending OID value. In this example, the condition is satisfied when an OID value of an object instance that is retrieved is not lexicographically between the starting OID value and the ending OID value of any pair of the one or more pairs.

摘要： A system for rapidly switching at least one virtual local area network (VLAN) from a first loop-free topology to a second loop-free topology in response to a failure within the first loop-free topology. Each VLAN has one “logical” VLAN which represents the network entities organized into the VLAN and a set of “physical” VLANs each having its own VLAN designation. For each physical VLAN, a different loop-free topology is defined, although only one physical VLAN is “active” at any given time. Messages associated with the logical VLAN are tagged with the designation of the currently active physical VLAN, and forwarded along its loop-free topology. Upon detecting a failure in the loop-free topology, the logical VLAN is rapidly switched to the loop-free topology defined by a second, back-up physical VLAN. Following the switch, messages associated with the logical VLAN are tagged with the designation of this back-up VLAN and are forwarded along its loop-free topology.

摘要： A method of operating a fault tolerant connection in a network is described. The network includes a number of network elements and a number of links. Each of the network elements is coupled to at least one other of the network elements by at least one of the links. The method identifies a first path and a second path. The first path is between a first one of the network elements and a second one of the network elements, as is the second path. Moreover, the first path and the second path are disjoint. This disjointedness can be any difference between the two paths (e.g., any combination of different network elements or links). A packet is sent from the first one of the network elements via the first path, while a duplicate packet is sent from the first one of the network elements via the second path. The duplicate packet is a duplicate of the packet. Once these packets have been sent, at least one of the packet and the duplicate packet are received at the second one of the network elements. If both the packet and the duplicate packet are received at the second one of the network elements, one of the two is discarded (e.g., by simply ignoring the last one received).
摘要翻译：描述了在网络中操作容错连接的方法。该网络包括多个网络元件和多个链路。每个网络元件通过链路中的至少一个耦合到网络元件中的至少另一个。该方法识别第一路径和第二路径。第一路径在网络元件中的第一路径和网络元件中的第二路径之间，和第二路径一样。此外，第一路径和第二路径是不相交的。这种不相容性可以是两个路径之间的任何差异（例如，不同网络元件或链路的任何组合）。经由第一路径从第一网络元件发送分组，同时经由第二路径从第一网络单元发送重复分组。重复的数据包是数据包的副本。一旦这些分组被发送，则在第二个网络单元中接收到分组和重复分组中的至少一个。如果在第二个网络元件处接收到分组和重复分组，则丢弃两个分组中的一个（例如，通过简单地忽略所接收的最后一个）。

摘要： A method and system for monitoring objects in a plurality of management information bases (MIBs) is provided. The objects required for functioning of an application are identified from the MIBs. The application identifies these objects. The identified OIDs are grouped in a group depending on grouping rules provided by the application. A rate for detecting changes in the group is provided. The changes in the group are detected at the provided rate. A notification is generated on detecting a change in the group. The notification is sent to the application. The notification reports a change in the identified OIDs in the group.
