Collaboration software with real-time synchronization
A collaboration program operates on a computer system for storing, sharing and synchronizing data between different users. Centrally stored content data items are organized by associations into one or more folders, with the folders arranged by associations in a multi-level hierarchical structure. Users have access to all folders and content data items falling within at least one top level folder or “file cabinet” viewable by that user. When a user makes a change/addition to the hierarchical structure, that change/addition is transmitted to a server, which makes the change/addition to the necessary associations and sends messages through a TCP/IP format advising other signed-on users of the change/addition. With each content data item having the capability of being associated into multiple folders and each folder having the capability of being associated into multiple other folders or file cabinets, the computer system operating the collaboration program gives different users simultaneous, synchronized access to the folders and content data items in the hierarchical structure.

Forward error correction for burst and random packet loss for real-time multi-media communication
This invention relates generally to a packet recovery algorithm for real-time (live) multi-media communication over packet-switched networks, such as the Internet. Such multi-media communication includes video, audio, data or any combination thereof. More specifically, the invention comprises a forward error correction (FEC) algorithm that addresses both random and burst packet loss and errors, and that can be adjusted to tradeoff the recoverability of missing packets and the latency incurred. The transmitter calculates parity packets for the rows, columns and diagonals of a block of multi-media data packets using the exclusive or (XOR) operation and communicates the parity packets along with the multi-media data packets to the receiver. The receiver uses the parity packets to recover missing multi-media data packets in the block. The FEC algorithm is designed to be able to recover long bursts of consecutive missing data packets. If some parity packets are missing, they too can be recovered using an extra single parity packet, so that they can be used to recover other missing data packets. The invention applies to both one-way real-time streaming applications and two-way real-time interactive applications, and to both wired and wireless networks. The invention retains backwards compatibility with existing standards governing FEC for professional video over IP networks.

Policy based auditing of workflows
An auditing system is disclosed comprising a Policy Validation Mechanism Program (PVMP) that operates in conjunction with a Workflow Engine (WE), and a Policy Validation Server Program (PVSP) that operates on a Policy Validation Server (PVS) connected to the WE by a secure communication link.

Segmenting data packets for over-network transmission at adjustable fragment boundary
A computing system includes a communication mechanism and a data packet dividing mechanism. The communication mechanism is communicatively coupled to a network to send first data packet fragments over the network. The data packet dividing mechanism is to segment first data packets into the first packet fragments at a dynamically adjustable fragment boundary, such that the dynamically adjustable fragment boundary changes every time n-bit identifiers of the first data packets roll over.
Method and apparatus for communicating protocol data unit in a radio access network
A new protocol data unit is used in communications in a radio access network. When a user equipment requests a radio resource controller connection, the UE includes its identity in the request message. In establishing the connection to UE, a serving radio network controller allocates a logical channel to the UE for communications and identifies the logical channel in the header of the protocol data unit so as to allow a receiver of the PDU to know the UE identity in an out-of-band signaling fashion, depending upon a state of the transmitter of the PDU. When the transmitter changes its state, the receiver can change state accordingly. The new PDU structure allows continuous reception of the HS-DSCH downlink channel during state transition form CELL_FACH or CELL_PCH or URA_PCH to CELL_DCH and vice versa. This new PDU structure also allows continuous HS_DSCH retransmissions.
Communication system and method for linking a communication network to a customer facility
A communication system for linking a communication network to a customer facility is provided according to an embodiment of the invention. The communication system includes the communication network, a network-side Unbundled Network Element (UNE) interface connected to the communication network, a first wireless transceiver adapted to communicate with at least a second, customer facility wireless transceiver at the customer facility, a customer-side UNE interface connected to the first wireless transceiver, and a plurality of UNEs extending between the network-side UNE interface and the customer-side UNE interface. A communication session between the communication network and the customer facility can be established by selecting and bonding one or more UNEs from the plurality of UNEs to form one or more bonded UNEs and exchanging communications between the communication network and the first wireless transceiver over the one or more bonded UNEs.
Systems and methods for providing framing mapping, muxing and data processing
A method and system for providing Layer 1 time division multiplexing (TDM) framing, multiplexing, and mapping as well as Layer 2 data and protocol processing. One embodiment of the invention provides an integrated Layer1/Layer2 service aggregator within a single-device. Such an embodiment provides a complete System-on-Chip implementation for clear channel and deeply channelized OC-48 (STM-16), 4×OC12/3 (STM4/1) application of 2,000 channels or more. One embodiment implements functionality of Layer2 data and protocol processing as well as Layer1 TDM framing, multiplexing and mapping. For one embodiment, target applications include packet-based transport systems, multi-service access and metro systems, switches and routers and ADM/MSPP systems.
System and method for IPv4 and IPv6 migration
A system, method, and computer-readable medium for IPv4 and IPv6 migration are provided. The invocation of NAPT-PT and NAPT are minimized inside a provider's network. NAPT-PT operations are invoked at most once inside the provider's network under all situations for a media path. Moreover, he minimum required NAPT operations are performed. If there is a required NAPT operation along the media path for IPv4 address realm mismatches, no NAPT-PT operation are performed solely for protocol conversion purposes.
