Abstract: In some embodiments, a method for supporting multiple devices on a high speed physical link may be described. An embedded device may assert a link request pin to request to transmit data on a multi-point communications link that may serve a plurality of embedded devices. A controlling device may receive the link request signal. When the controlling device finishes sending data on the link, it may address the plurality of embedded devices in a round robin format and may determine which device asserted the link request pin. The embedded device that asserted the link request pin may send an acknowledgement signal to the controlling device when it is addressed.

Abstract: A system selectively drops data from queues. The system includes a drop table that stores drop probabilities.

Abstract: Internet Protocol address prefixes are hashed into hash tables allocated memory blocks on demand after collisions occur for both a first hash and a single rehash. The number of memory blocks allocated to each hash table is limited, with additional prefixes handled by an overflow content addressable memory. Each hash table contains only prefixes of a particular length, with different hash tables containing prefixes of different lengths. Only a subset of possible prefix lengths are accommodated by the hash tables, with a remainder of prefixes handled by the content addressable memory or a similar alternate address lookup facility.

Abstract: A protocol for a peer power save mode (PPSM) in a tunneled direct link setup (TDLS) wireless network and a system therefor are provided. A station (STA) set up a TDLS link can send a frame having a power management bit set to a peer STA to enter into a power save mode (PSM). In this case, the station entering into the PSM operates in a PPSM client mode. When the peer STA operates in the PPSM client mode, the STA can operate in the PPSM access point (AP) mode or can enter into the PPSM client mode. The STA operating in the PPSM AP mode buffers data for the STA operating in the PPSM client mode and informs the peer STA of information indicating that there is buffered data by the use of a peer traffic indication frame or the like. In principle, a U-APSD procedure can be applied to the transmission of data through a direct link from the STA operating in the PPSM AP mode to the STA operating in the PPSM client mode.

And, the third handler extracts a mobile service identifier and a content identifier of a first data type from the first signaling information and constructs content identification information of a second data type.

The digital communications system includes an OTN network, and at least one source device and at least one destination device connected to the network via respective 10Gbase-R interfaces. The system transports 10 GbE LAN data packets over the OTN network by performing decoding on the packets to recover the preamble and variable length data contained in each packet, removing the IPG between successive packets in the stream, encapsulating the packets including the respective preambles and data, and mapping the encapsulated packets to the overhead and payload areas of ODUk frames. The packets are then transported over the OTN network from the source device to the destination device.
