Abstract: During operation, an electronic device may store, in memory, information associated with operation of the electronic device, such as during communication and processing of one or more packets or frames. Furthermore, an error-event monitor in the electronic device may, during a time interval, analyze at least a portion of the stored information to detect an occurrence of an error event in one or more types of error events in the electronic device. When the error event occurs during the time interval, the electronic device may perform a remedial action and may persist, in the memory, at least a second portion of the stored information associated with the error event. Otherwise, when the error event does not occur during the time interval, the electronic device may overwrite, in the memory, the stored information with additional information associated with operation of the electronic device during subsequent communicating and processing.

Abstract: Using a hash function, an L2/L3 switch can produce an FID for a data packet. The L2/L3 switch can select, from among potentially several stored VLAN flooding tables, a particular VLAN flooding table that is associated with a particular VLAN on which the data packet is to be carried. The rows of the particular VLAN flooding table can specify different combinations of the particular VLAN's egress ports. The L2/L3 switch can locate, in the particular VLAN flooding table, a particular row that specifies the FID. The L2/L3 switch can read, from the particular row, a specified subset of the egress ports that are associated with the particular VLAN. The L2/L3 switch can transmit copies of the data packet out each of the egress ports specified in the subset, toward analytic servers connected to those egress ports.

Abstract: A GTP correlation cluster (GCC) can automatically program a network element to forward copies of packets originating from a mobile device and having a shared attribute to the same analytic server, regardless of the regions into which the mobile device moves. The GCC can monitor attributes of copies of control packets that the network element receives. In response to detecting a changed attribute within a control packet originating from a mobile device, the GCC can update a session map specific to that mobile device in order to cause packets having that changed attribute to be forwarded to the same port to which packets having the former attribute were being forwarded prior to the change. As a result, the network element can ensure that packets belonging to a particular session still are forwarded to the same analytic server even if the mobile device has moved to a different region.
