  • METHODS OF ESTABLISHING VIRTUAL CIRCUITS AND OF PROVIDING A VIRTUAL PRIVATE NETWORK SERVICE THROUGH A SHARED NETWORK, AND PROVIDER EDGE DEVICE FOR SUCH NETWORK
    Publication number: 20140204951
    Abstract: A virtual private network (VPN) service is provided through a shared network infrastructure comprising interconnected provider edge (PE) devices having customer edge (CE) interfaces. Some of the CE interfaces are allocated to a VPN supporting virtual LANs. A correspondence between a CE interface and a virtual LAN is learnt on the basis of tagged frames received at this CE interface and including an identifier of this virtual LAN. The learning process permits the detection of pairs of CE interfaces which correspond to a common virtual LAN. Upon such detection, a virtual circuit is established in the shared network infrastructure between the PE devices having these CE interfaces, and subsequently used for forwarding frames including the identifier of the common virtual VLAN.

  • OPTICAL SWITCH AND PROTOCOLS FOR USE THEREWITH
    Publication number: 20140205287
    Abstract: A method of establishing a data connection between terminal switching nodes in a network and switching nodes for implementing the method. The method involves switching nodes participating in a network layer wavelength routing (WR) protocol to determine the next hop switching node for every possible combination of terminal nodes based on the network topology. The method also involves the switching nodes participating in a network layer wavelength distribution (ND) once the data connection is to be established. The WR protocol determines the path used through the network, while the WD protocol assigns wavelengths on each link between switching nodes. The wavelengths may be different on different optical links. The switching nodes include wavelength converters with an optical switch or optoelectronic converters with a digital electronic switch. A digital electronic switch can also provide signal reformatting.

  • Dynamic establishment of virtual circuits multisegment pseudowires
    Patent number: 8787218
    Abstract: The present invention provides a technique for automatically establishing a virtual circuit from one edge device to another through a core network. The virtual circuit may comprise one or more pseudowire segments. These pseudowire segments extend between adjacent edge and core devices within the core network. Pseudowire segments through the core network are automatically stitched together as a setup message is forwarded from a first edge device to a second edge device through the core network. A virtual circuit is established in one direction, and packets are forwarded in an opposite direction. With the present invention, a virtual circuit comprising any number of pseudowire segments, as well as two attachment circuits, may be established in an automatic and efficient manner upon being initiated by the first edge device.

  • FORCED HOLD CALL HANDLING IN A VOP ENVIRONMENT
    Publication number: 20140198787
    Abstract: The present invention provides a technique for providing a forced hold service such as is used for an emergency services call, which is supported at least in part over a packet network. The forced hold service acts to effectively hold a connection for the call with a called party, even when the caller takes an action that would normally end a call, such as going on hook, pressing end, or the like. When the caller takes an action that would normally end the call, the forced hold service allows the caller to automatically reconnect to the emergency services provider over the held connection upon going offhook, pressing send, or the like. Alternatively, the emergency services provider can effectively re-engage the call wherein the caller is reconnected over the held connection upon going offhook, pressing send, or the like.

  • SELECTIVE PROCESSING OF DAMAGED PACKETS
    Publication number: 20140198632
    Abstract: When a damaged packet has been forwarded to or towards a destination terminal, a forwarding device or a destination terminal will determine if the packet is damaged, and if it is damaged, determine whether the content of the packet is time-sensitive. If the content is time-sensitive, the damage to the packet is assessed, and if possible, an attempt to repair the damage is made. Repair may include correcting the damaged data or packet, deciding to use the damaged data because the damage is minimal, or replacing all or a part of the damaged data with a normalized set of data. If repair is not possible and replacement of the damaged portion is not available or desirable, the packet is discarded.

  • Allocating internet protocol (IP) addresses to nodes in communications networks which use integrated IS-IS
    Patent number: 8782226
    Abstract: Previously it has only been possible to allocate unique internet protocol (IP) addresses to nodes in open systems interconnection (OSI) communications networks such as those using integrated IS-IS, by manual configuration. This is time consuming and expensive because an operator must travel to the site of the node. By exploiting features of the OSI routing protocol the present invention enables IP addresses to be automatically allocated to the new network nodes. This is particularly advantageous for new intermediate systems such as optical multiplexers with integral routers. Once an IP address has been allocated, the node can be managed by a remote management system or operator using internet protocol methods.

    Patent number: 8782230
    Abstract: An XML accessible network device is capable of performing functions in response to an XML encoded request transmitted over a network. It includes a network data transfer service, coupled to a network, that is capable of receiving XML encoded requests from a client also connected to the network. A service engine is capable of understanding and parsing the XML encoded requests according to a corresponding DTD. The service engine further instantiates a service using parameters provided in the XML encoded request and launches the service for execution on the network device in accordance with a command design parameter. A set of device APIs interacts with hardware and software on the network device for executing the requested service on the network device. If necessary, a response is further collected from the device and provided to the client in a response message.

  • Method and Apparatus for Generating Large Numbers of Encryption Keys
    Publication number: 20140192979
    Abstract: Entropy obtained from a series of key generation exchanges may be combined with entropy from a strong entropy source to allow the strong entropy to be stretched to generate a larger number of keys for use on a communication network, without requiring additional information from the group members and without requiring the entropy source to be increased in size or in number. In one embodiment, nonces exchanged during an initial key exchange are used to generate additional key material that is then fed, together with a fresh random secret, to another pseudo-random function to generate an additional key stream. The methods are particularly useful for group key management where a large number of keys are required to be generated in a short time frame.

  • RESILIENT ATTACHMENT TO PROVIDER LINK STATE BRIDGING (PLSB) NETWORKS
    Publication number: 20140177433
    Abstract: A system for interfacing a client system in a first network domain with a Provider Link State Bridging (PLSB) domain includes at least two Backbone Edge Bridges (BEBs) of the PLSB domain. Each BEB is an end-point of a connection in the first network domain to the client system and an end-point of at least a unicast path in the PLSB domain. An inter-node trunk is provided in the PLSB domain for interconnecting the BEBs. A phantom node is defined in the PLSB domain and is notionally located on the inter-node trunk. Each of the BEBs is configured such that: an ingress packet received from the client system via the connection in the first network domain is forwarded through a path notionally rooted at the phantom node; and an egress packet destined for the client system is forwarded to the client system through the connection in the first network domain.

  • PROVIDING-REPLAY PROTECTION IN SYSTEMS USING GROUP SECURITY ASSOCIATIONS
    Publication number: 20140181967
    Abstract: A method and apparatus is disclosed which enables detection of undesired packets received at a device in a network, where the device is a member of a group of devices in the network. A registration table stores transform identifiers for each member of a group and controls the forwarding of the transform identifiers to the members of the group as members are added and deleted. A transform identifier indicates a format or transformation of a packet transmitted by an associated member. The transform identifier can therefore be used at a receiving device to distinguish between transmissions by different members of the group, thereby enabling the receiving device to extract sequence information associated with the member from the packet. The sequence information can be compared against an expected sequence number for the member to determine whether the packet is an undesirable or rogue packet.
