In some embodiments, a non-transitory processor-readable medium includes code to cause a processor to receive at a tunnel server, a data unit addressed to a communication device, and define, a first instance of the data unit and a second instance of the data unit. The first instance of the data unit is sent to the communication device via a first tunnel defined between at least the tunnel server and a first base station associated with a first network. The second instance of the data unit is sent to the communication device via a second tunnel defined between at least the tunnel server and a second base station associated with a second network. The second instance of the data unit is dropped by the communication device when the first instance of the data unit is received before the second instance of the data unit.

A method of sending data to a switch fabric includes assigning a destination port of an output module to a data packet based on at least one field in a first header of the data packet. A module associated with a first stage of the switch fabric is selected based on at least one field in the first header. A second header is appended to the data packet. The second header includes an identifier associated with the destination port of the output module. The data packet is sent to the module associated with the first stage. The module associated with the first stage is configured to send the data packet to a module associated with a second stage of the switch fabric based on the second header.

A security device may receive information identifying a set of conditions for providing countermeasure code to a client device. The security device may receive information identifying an action to be performed when the countermeasure code is executed by the client device, and may determine the countermeasure code to be provided to the client device when the set of conditions is satisfied. The security device may receive a request from the client device, and may determine a response to the request. The response may include response code for serving content of a web page to the client device. The security device may determine that the set of conditions has been satisfied, and may insert the countermeasure code into the response code. The security device may provide the response code and the countermeasure code to the client device, and the countermeasure code may cause the client device to perform the action.


In general, this disclosure describes techniques for applying, with a network device, subscriber-specific packet processing using an internal processing path that includes service objects that are commonly applied to multiple packet flows associated with multiple subscribers. In one example, a network device control plane creates subscriber records that include, for respective subscribers, one or more variable values that specify service objects as well as an identifier for a packet processing template. A forwarding plane of the network device receives and maps subscriber packets to an associated subscriber record and then processes the packet by executing the packet processing template specified by the subscriber record. When the forwarding plane reaches a variable while executing the specified packet processing template, the forwarding plane reads the associated variable value from the subscriber record to identify and then apply the subscriber-specific service object specified by the variable.

In some embodiments, a method includes calculating, at a wireless access point (WAP) from a set of WAPs within a network, an interference value for each channel from a set of channels of the WAP. The method includes calculating, based on the interference value for each channel, a total move weight of the WAP. The method includes receiving, at the WAP, a total move weight from each remaining WAP. The method includes selecting one WAP from the set of WAPs based on a random number, the total move weight of the WAP, the total move weights from the remaining WAPs, and a rank of the WAPs. The method further includes changing, if the WAP is selected, a designated channel of the WAP to one of the remaining channels; and sending a signal to modify an active channel of the WAP to correspond with the designated channel.
