20090073988 | SYSTEMS AND METHODS FOR A SELF-HEALING CARRIER ETHERNET TOPOLOGY - 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. | 03-19-2009 |
20090141703 | SYSTEMS AND METHODS FOR CARRIER ETHERNET USING REFERENTIAL TABLES FOR FORWARDING DECISIONS - 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.

20140177637 | REDUCED COMPLEXITY MULTIPROTOCOL LABEL SWITCHING - A reduced complexity Multiprotocol Label Switching (MPLS) method, a MPLS network element, and a MPLS network utilize an MPLS operating regime whereby disjoint sets of one or more MPLS labels are uniquely and specifically associated with just one switch, i.e. each switch node is assigned one or more non-overlapping labels from the RFC 3032 20 bit label space to bind to particular service end-points; which then enables these labels to embody the core properties of a destination address (DA) in the network sub-domain in which they are used. The central property is that these DA labels are constant for a given forwarding path across the entire sub-domain, remaining unchanged at any point in the network. Once that is achieved, any and all hop-by-hop signaling protocols are unnecessary, since there is no need for label swapping, and the label-switching-node binding information can be flooded by interior routing protocols only. | 06-26-2014 |
