  • Patent number: 9621470
    Abstract: Existing resource reservation techniques are inefficient for M2M communications. In an example embodiment described herein, a system comprises a service layer server that resides on a service layer and a control plane node that resides on an access network, wherein the service layer server communicates with the control plane node via a control plane interface. The control plane interface can be used to configure quality of service (QoS) policies (rules) that are based on an object that is being addressed. In this context, for example, an object may be a memory location or value. For example, the service layer may configure one or more QoS rules for the access network based on the object by sending a QoS provisioning message that includes one or more parameters to the control plane node. The control plane node may determine the object that is identified in the one or more QoS rules, and the QoS rules may be distributed to one or more routers that may be used to access the object.

  • Patent number: 9065723
    Abstract: An unaddressed device installed inline in a path of an MPLS network can communicate a packet from within the MPLS network to an upstream device without knowledge of the necessary MPLS labeling by sending the packet intentionally in the wrong direction: downstream. To communicate to an upstream device, the unaddressed device sends a packet downstream into the MPLS network on the opposite side and through the opposite outgoing port from that which would be used for a packet sent to the same device in a non-MPLS network. This behavior forces the MPLS network, when it next inspects the packet, to re-label it with the correct labeling to route the packet on a path back upstream to the recipient device. In this manner, the MPLS architecture is used to redirect or loop back packets from an unaddressed inline device to the upstream device.

  • Patent number: 8976795
    Abstract: A computing environment containing a mesh network that is adapted to provide a reliable transport mechanism over which services may be delivered. Nodes of the mesh can automatically select routable addresses without conflicts, which allows nodes of the mesh to be accessed, even as the mesh changes through the addition or deletion of nodes. Also, nodes communicate with a protocol that supports service advertisements. These advertisements can identify mesh nodes that supply services, such as file or print servers, for which devices that have not yet connected to the network may be searching. Advertisements can also identify services to be used by nodes in the network, allowing, for example, a node to select a gateway providing a reliable connection to an external network. The mesh network can be used as a transport for communication using protocols, such as TCP/IP, that generally exhibit poor performance when using unreliable transports.

  • Patent number: 8971332
    Abstract: Nodes on a link state protocol controlled Ethernet network implement a link state routing protocol such as IS-IS. Nodes assign an IP address or I-SID value per VRF and then advertise the IP addresses or I-SID values in IS-IS LSAs. When a packet is to be forwarded on the VPN, the ingress node identifies the VRF for the packet and performs an IP lookup in customer address space in the VRF to determine the next hop and the IP address or I-SID value of the VRF on the egress node. The ingress node prepends an I-SID or IP header to identify the VRFs and then creates a MAC header to allow the packet to be forwarded to the egress node on the link state protocol controlled Ethernet network. When the packet is received at the egress node, the MAC header is stripped from the packet and the appended I-SID or IP header is used to identify the egress VRF.

  • Patent number: 8937864
    Abstract: Channel quality of an airlink is assessed at an edge router of a radio-access communication network. Based on the assessment, the cause of lost data is determined to be due to traffic congestion or due to poor channel quality. In the latter case, congestion recovery/avoidance processes of a transport protocol of over a spliced transport connection can be overridden to avoid unnecessary limitations to data flow.

  • Patent number: 8929364
    Abstract: A new type of Provider Edge (PE) device is used to support BGP-based IP-VPNs. Each VRF instance in a PE device is associated with a dedicated IP address (Service IP address). Each service IP address is dedicated to a VRF in a PE device. The service IP address is distributed by BGP for VPN route association. Customer/VRF IP packets can be sent to a VRF instance in the egress PE device using service IP header encapsulation (with IP Destination Address=Service IP address of egress PE's VRF & IP Source Address=Service IP address of ingress PE's VRF). This obviates the need for explicit tunnels in the core.

  • Patent number: 8923302
    Abstract: A set of globally-reachable attachment registers is provided for objects in an internetwork of interconnected communications networks. “Objects” can be networks, hosts or terminals, or passive objects which themselves do not have a network interface. Each attachment register corresponds to an object in the internetwork. The attachment registers are not located with their respective object. Information is stored in the attachment registers that establishes one or more logical links between the attachment registers. The information is used to perform one or more network communication functions, and in particular to determine a locator by identifying a logical path, along the logical links between attachment registers, from a destination attachment register corresponding to the destination object. Other non-limiting example functions include location registration and update, name to global locator resolution, routing, multi-homing, dynamic ISP selection, and handover.
