For each packet of the packets, the length of the packet is compared with a threshold length. An encoded length for each of the packets is stored in a sideband memory, the encoded length for each packet of the packets being: (i) the length of the packet if the length satisfies the threshold; or (ii) a predefined value if the length of the packet does not satisfy the threshold. As each packet of the packets is read from the buffer memory, an end location of the packet is determined responsive to the encoded length thereof in the sideband memory.

    Abstract: Methods and apparatus for communicating between an access terminal (AT) and remote device via an access point (AP) are described. For communications over the air link, between an AP and an AT, a short address corresponding to the remote device is used for routing packets to/from the remote device. This conserves air link resources. However, for communicating between the AP and the remote device a longer address, e.g., a full IP address corresponding to the remote device, is used. The AT converts between the long and short addresses as information, e.g., packets, is communicated between the remote device and the AT. The long address may be, for example, an IP address corresponding to the remote device used to route packets through a Layer 2 tunnel between the remote device and the AP. In some embodiments the remote device is a remote access point.

  • Patent number: 8036243
    Abstract: A single chip protocol converter integrated circuit (IC) capable of receiving packets generating according to a first protocol type and processing said packets to implement protocol conversion and generating converted packets of a second protocol type for output thereof, the process of protocol conversion being performed entirely within the single integrated circuit chip. The single chip protocol converter can be further implemented as a macro core in a system-on-chip (SoC) implementation, wherein the process of protocol conversion is contained within a SoC protocol conversion macro core without requiring the processing resources of a host system. Packet conversion may additionally entail converting packets generated according to a first protocol version level and processing the said packets to implement protocol conversion for generating converted packets according to a second protocol version level, but within the same protocol family type.

  • Publication number: 20110243154
    Abstract: A method and circuit for implementing variable length packets to embed extra control information in an interconnect system, and a design structure on which the subject circuit resides are provided. Packets are defined to include an End-to-End (ETE) Flow Unit within packet (Flit) count field in the packet header. The packet header also includes its own CRC field. When a nonzero ETE flit count field is received in an incoming packet from an incoming link, the specified number of embedded ETE flits is removed from the packet and is used the same as if the control information arrived in its own packet.

  • Patent number: 8018932
    Abstract: Methods and apparatus are disclosed for sending a multicast packet from multiple network interfaces across multiple networks using the same media access source address (MAC source address). One implementation includes a processing element and a network interface for each of the multiple networks. The processing element generates and initiates sending of a multicast packet having a same media access source address (MAC source address) from at least two of the multiple network interfaces. In one implementation, a single copy of the multicast packet is buffered, and each of the network interfaces retrieves, such as via a direct memory access (DMA) request, the multicast packet and forwards it to an attached network.

  • Patent number: 8018942
    Abstract: A recognition system for recognizing a data packet includes a data memory for storing data units in a predetermined order. A first data unit includes an instruction for determining a characteristic of the data packet. The first data unit also includes the total number of the data units, and a corresponding sequence number for the first data unit. The recognition system further includes a matching processor coupled to the data memory. The matching processor can execute the instruction in the first data unit to generate a result. The matching processor can also provide an address pointer according to the execution result, the total number of the data units, and the corresponding sequence number of the first data unit.

  • Patent number: 8018936
    Abstract: A method and apparatus is shown for communicating Fibre Channel frames between distinct fabrics. A proxy zone is established in each fabric with a physically present local device and a remote fabric device. A router creates a proxy device in each fabric for every device not physically connected to the fabric. The proxy devices appear to be directly attached to the router. The router handles all address translations between proxy and physical addresses. When multiple routers are encountered, the ingress router does all address translation. No routing or encapsulation headers are used except when routing between two routers. The source ID and the originator exchange identifier are stored at the egress router for all link requests that require special handling. When replies pass through that router, the destination ID and originator exchange identifier are compared with the stored information. On a match, the reply is specially handled.

  • Patent number: 8018948
    Abstract: In one embodiment, a security gateway receives an IPSec Initiation (IPSec INIT) request from a client. The security gateway may communicate with a AAA server to authenticate the client. After authentication, the security gateway intercepts a URR Discovery request from the client. The security gateway determines registration information for a response to the registration request. The registration information may be information on where the client can locate a D-GANC. A response is generated using the determined information and sent to the client. The response to the discovery request is performed without communicating with a P-GANC. Accordingly, a security gateway is used to authenticate the client and also to respond to the discovery request. This does not require that a P-GANC function be deployed in a network. Thus, cost and processing power may be saved.

  • Patent number: 8014377
    Abstract: A mobile terminal in a wireless communication network may be one of several modes of operation. When in an idle mode, the mobile terminal may avoid a lengthy random access procedure normally associated with responding to a page from a base station, if the base station includes in the page an indication of a resource that the mobile terminal may utilize when responding to the page. Additionally, the mobile terminal may transmit an efficient location update MAC header to a base station, whether prompted to by a page from the base station or not. Furthermore, without leaving the idle mode or a sleep mode, the mobile terminal may exchange short data burst messages with a base station.

  • Patent number: 8014396
    Abstract: A base station apparatus that limits the influx of speech data into a packet channel and that enables the service quality of the packet channel to be prevented from degrading. In this apparatus, a protocol detecting section (301) detects a protocol contained in an IP header of a packet. Based on the protocol, a packet type detecting section (302) detects a type of packet. Based on the type of packet, a delay addition control section (303) determines whether or not to add a delay. Specifically, when the packet is of VoIP, the delay addition control section (303) instructs a switching section (304) to output the packet to a delay adding section (103), and further instructs the delay adding section (103) to add a delay. Meanwhile, when the packet is an IP packet, the delay addition control section (303) instructs the switching section (304) to output the packet to a scheduler (104).
