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.

In one embodiment, a method includes receiving a request for a multimedia object from a mobile-client system of a first user, wherein the request comprises http-header information of the mobile-client system, determining one or more attributes of the mobile-client system based at least on a social-graph information associated with the first user and the http-header information, wherein determining the one or more attributes comprises calculating a probability score the mobile-client system has the one or more attributes by comparing the social-graph information associated with the first user and the http-header information with a database of a social-networking system, and sending the multimedia object to the mobile-client system in response to the request, the multimedia object being customized based on at least the determined one or more attributes of the mobile-client system.
Abstract:
A method for improving client subnet efficiency by equivalence class aggregation includes receiving a Domain Name System (DNS) query from a client, determining, based on predetermined class criteria, that the client is associated with an equivalency class, searching a cache associated with the equivalence class for an answer corresponding to the DNS query, and upon locating the answer, serving the answer to the client. If it is determined that the cache does not include the answer, the method proceeds with querying, by a recursive server, an authoritative server using client subnet data associated with the equivalence class, receiving the answer from the authoritative server, storing the answer to the cache associated with the equivalency class, and serving the answer to the client. The client subnet data may include a representative CIDR block, the representative CIDR block being used to make queries on behalf of all clients associated with the equivalence class.
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:
In an embodiment of the invention, a method of performing a byte-rotate-merge on computer hardware is discussed. Byte-rotating is performed on first and second source operands and are byte-rotated by first and second rotation constants respectively. The first byte-rotate output and the second byte-rotate output are merged. Bytes from the first byte-rotate output are output to a byte-rotate-merge output when control bits from a byte-mask are logical ones. Bytes from the second byte-rotate output are output to a byte-rotate-merge output when control bits from the byte-mask are logical zeros.
Abstract:
A system for assigning communications addresses within a network is provided. The system comprises a memory and at least one processor coupled to the memory. The at least one processor coupled to the memory being configured to instruct each device of a plurality of devices to generate an identifier by transmitting a message to the plurality of devices using a default address, each device of the plurality of devices having an active address set to the default address instruct each device having an identifier within a range of identifiers to transmit a response including the identifier, and respectively assign a communications address to each device that transmits a response including a unique identifier.

Abstract:
The present disclosure describes message forwarding in a network where Virtual Local Area Networks (VLANs) are deployed over geographically dispersed sites. The network comprises a first aggregation layer device at a first site and second first aggregation layer device at a second site. The first aggregation layer device learns Media Access Control (MAC) address information received from the second aggregation layer device. The MAC address information includes: a VLAN identifier (ID), an aggregated MAC address and an aggregated MAC address mask configured at the second site. When receiving a message addressed to the VLAN ID and a destination MAC address, the first aggregation layer device searches for the MAC address information based on the VLAN ID and destination MAC address and forwards the message to the second aggregation layer device according to the MAC address information. The destination MAC address belongs to the same MAC address segment as the aggregated MAC address and searching for the MAC address information comprises mask matching based on the aggregated MAC address mask.
Abstract:
An apparatus comprising a plurality of district boundary bridges (DBBs) in a plurality of second network districts configured to couple to a plurality of core bridges in a core network district and to a plurality of end-stations in the second network districts via a plurality of intermediate switches in the second network districts; wherein the core bridges and the DBBs are aware of a plurality of Media Access Control (MAC) addresses of the DBBs but are not aware of Internet Protocol (IP) addresses and MAC addresses of the end-stations, and wherein the IP addresses of the end-stations are mapped in a directory service (DS) in the core network district to the MAC addresses of the corresponding DBBs in the corresponding second network districts of the end-stations.
