Abstract: A device may receive a route identifier that includes a range identifier or a configuration identifier. The range identifier may identify a range of broadcast domain identifiers associated with a first device. The configuration identifier may identify an Ethernet segment identifier (ESI) configuration of the first device. The device may identify the range identifier or the configuration identifier included in the route identifier. The device may select a designated forwarder from among multiple devices based on the range of broadcast domain identifiers or based on identifying the configuration identifier. The designated forwarder may be the same designated forwarder selected by at least one other device.

Abstract: A method and apparatus for providing a masked short message service in a wireless network are disclosed. For example, the method receives a message from a first endpoint device directed to a second endpoint device, wherein the message indicates that the message is a masked short message service message, and forwards the masked short message service message with a code towards the second endpoint device. In one example, the second endpoint device parses the message and executes instructions contained therein, e.g., for sending a regular SMS with content derived from masked SMS, making a call, playing music, finding location by invoking an API, sending a file or a picture and any other functions that the second endpoint device may be capable of doing. The masked short message service provides a method for remotely controlling a 2G/3G mobile device through a computer or another mobile device.

Abstract: Systems and methods for storing and managing pools of network addresses. An example method may comprise: identifying, in a data structure representing a pool of network addresses, an index value of an element having a defined state; determining, by a processing device, a network address in view of the index value and a base network address associated with the pool; and modifying the state of the element of the data structure.

Abstract: A method and apparatus of a device that determines a match for a destination address using an exact match table and a longest prefix match table of a network element is described. In an exemplary embodiment, the network element receives a data packet that includes a destination address. The network element generates a key for the destination address, wherein the key represents more addresses than the destination address. The network element further performs an address lookup using the key in an exact match table. Furthermore, a match in the address lookup indicates a first transmitting interface of the network element. The network element additionally performs an address lookup using the destination address with a longest prefix match table, wherein a match in the address lookup indicates a second transmitting interface of the network element. In addition, the network element determines a resulting transmitting interface based on results from the exact match table address lookup and the longest prefix match address lookup. The network element forwards the data packet using the transmitting interface.

Abstract: An integrated control device, to implement automatic address assignment in a path spanning two or more administrative domains, and to implement communication between a plurality of administrative domains, acquires definition information that defines protocols used in each administrative domain from an inter-administrative domain communication protocol stack list table, acquires available addresses of each protocol in each administrative domain which can be used for communication between the respective administrative domains from an available address range table, acquires a communication route from a starting point administrative domain to an ending point administrative domain, specifies domains that use the respective protocols on the communication route by using the definition information, assigns protocol information such as available addresses of each protocol between the specified domains by using an available address range table and notifies the assigned address to each domain.

Abstract: Various embodiments of the present disclosure provide methods for randomly mapping entries in a suitable lookup table across multiple switch devices and/or multiple switch chipsets in each of the multiple switch devices by using two or more independent hash functions. In some embodiments, the number of entries in the lookup table is equal to be the least common multiple of all possible M (i.e., a number of switch devices) choosing R values (i.e., a desired redundancy level).

Abstract: A method and system are disclosed for providing a service to bypass carrier grade NAT (CGN). A first and second range of private IPv4 addresses are generated for mapping to public IPv4 addresses. Subscribers to the service are provided terminals with a status code which indicates its status with respect to the service. The terminal is assigned a private IP subnet within the first range of private IPv4 addresses, if the status code is indicative of a bypass status and the terminal identifies a bypass device that requires access to inbound traffic from the public network. Each bypass device is assigned a private IPv4 address from the first range, and the bypass device's private IPv4 address is mapped to a public IPv4 address. Inbound traffic having a matching public IPv4 destination address is subsequently directed to the bypass device.

Abstract: Technologies for tracking out-of-order network packets include a target computing node coupled to a source computing node via a communication channel. The target computing node is configured to allocate a small window in memory in which to store a bit mask corresponding to a number of out-of-order network packets received from the source computing node via the communication channel. The target computing node is further configured to update the bit mask in the small window upon receiving an out-of-order network packet from the source computing node. The target computing node is additionally configured to allocate a large window in memory in response to a determination the size of the bit mask is larger than the size of the small window, store the bit mask in the large window, and store a pointer to the large window in the small window. Other embodiments are described and claimed.
