Abstract: The present invention utilizes specific referential tables for forwarding decisions while maintaining current mechanisms of Ethernet addressing and QoS marking. The referential tables are utilized for forwarding decisions based on any and/or multiple fields within the packets simultaneously, such as, for example, incoming port number, incoming MAC, incoming VLAN, outgoing MAC, outgoing VLAN, P-bits, DSCP, MPLS label, TCP/UDP port numbers, IP, SIP, HTTP, and the like. A user can define the forwarding criteria based on any combination/permutation fields in the packet. Advantageously, the present invention removes the need to introduce explicit tunnel labels in the Ethernet frame in order to maintain the desired QoS within the network removing explicit labeling requirements.

Abstract: The present disclosure relates a network, a network element, a system, and a method providing an efficient allocation of protection capacity for network connections and/or services. These may be for services within a given Virtual Private Network (VPN) or Virtual Machine (VM) instance flow. Network ingress/egress ports are designed to be VM instance aware while transit ports may or may not be depending on network element capability or configuration. A centralized policy management and a distributed control plane are used to discover and allocate resources to and among the VPNs or VM instances. Algorithms for efficient allocation and release of protection capacity may be coordinated between the centralized policy management and the distributed control plane. Additional coupling of attributes such as latency may provide more sophisticated path selection algorithms including efficient sharing of protection capacity.

Abstract: Systems and methods for self-healing Ethernet topologies which are compatible with PBT, which use standards-based protocols, which do not self-configure, and which use Ethernet OAM are provided. Interconnected nodes are configured with a primary and secondary path which is determined by VLANs, MPLS label, Provider Backbone Bridge Traffic Engineering (PBB-TE) VLAN ID (VID), Frame Relay (FR), Asynchronous Transfer Mode (ATM) Virtual Circuits (VCs), and the like. One or more head-end nodes are designated for terminating each path and for performing cross-connects between the primary and secondary paths. IEEE 802.1ag Continuity Check Messages (CCM) are transmitted by all nodes on both the primary and secondary routes. Responsive to a loss of a predetermined number of CCM messages, traffic is switched to the secondary route. In non-fault conditions, both the paths for the primary and secondary routes can carry traffic.

The present disclosure combines existing OTN FEC with a radio FEC or with an over-the-air FEC to reduce the OTN FEC. Additionally, the present disclosure utilizes unused overhead to communicate RF data rates between radios.

Abstract: Apparatus and method that increases bandwidth and reliability of digital subscriber line (DSL) connections. The system involves provisioning multiple DSL lines, splitting traffic into cells, transmitting the cells independently of each other, and reassembling the cells at the destination. Sequence numbers may be used when reassembling the cells. Virtual circuits (VCs) may be constructed across the DSL lines. Accordingly, a failure in one DSL line merely reduces the bandwidth without disruption to the customer. In this manner, the customer can be inexpensively provided with increased bandwidth and reliability.

Abstract: Apparatus implements combined packetized time-division multiplexed (TDM) streams and TDM cross connect functions. The apparatus includes an input buffer, a reassembly state machine, a frame buffer, and a segmentation state machine. The frame buffer includes multiple bins for storing cell data. The segmentation state machine retrieves information from the bins as associated with each DS0 and assembles output cells for transmitting output DS0s. The cells may be in asynchronous transfer mode (ATM) format, allowing a single ATM backplane to be used for voice signals, data signals, and combined voice/data signals. Various types of ATM cell formats are supported.

Abstract: A combined wide area network (WAN) port/synchronization unit that receives inputs including data and timing information and that synchronizes the data for transmission. The unit includes the following components. A network interface receives the input and removes data and primary timing information from the input. A data-path function processes the data. A reference selection unit receives timing information from the network interface as well as timing information from a secondary combined WAN port/synchronization unit. A synchronization control unit selects the most reliable timing information from the plurality of timing information inputs to the reference selection unit. A multiplexor multiplexes the timing information with the processed data across a link.
