A Point of Local Repair (PLR) network element includes one or more ports and circuitry connected thereto for forwarding and control, wherein the circuitry is configured to receive a PATH message for a Label Switched Path (LSP) tunnel in a Multiprotocol Label Switching (MPLS) network with a specified DiffSery Traffic Engineering (DSTE) Class Type, determine the DSTE Class Type based on the PATH message, and store the DSTE Class Type for the LSP tunnel to ensure a Facility Bypass tunnel used for the LSP tunnel supports the specified DSTE Class Type. The circuitry can be further configured to, responsive to a failure of the LSP tunnel, select the Facility Bypass tunnel for the LSP tunnel such that the Facility Bypass tunnel supports the specified DSTE Class Type.

SELECTIVE MULTICAST ETHERNET TAG EXTENSION FOR OPTIMAL SOURCE DRIVEN MULTICAST FORWARDING

A networking environment includes a first node and a second node configured as Ethernet Virtual Private Networking (EVPN) peers on an EVPN subnet that is coupled to a Layer 3 VPN over a core network. The first node receives a first multicast join request from a third node in the core network, the first multicast join request including a source address and multicast group address of a source of a multicast stream. The first node determines that the source address and the multicast group address for the source are behind the EVPN subnet at the second node. The first node sends to the second node, a control plane join request message that includes a receiver identifier that identifies the third node as a receiver of the multicast stream, the receiver identifier enabling the second node to forward the multicast stream directly into the core network to the third node.

Framework for temporal label switched path tunnel services
11121975 · 2021-09-14 · ·

A method for establishing a temporal label switched path (T-LSP) implemented in a node in a network. The method includes receiving a path request including a time interval and a set of constraints; obtaining traffic engineering information from a first database; computing, by the node, a path satisfying the time interval and the set of constraints based on the traffic engineering information obtained; storing the time interval and the set of constraints in a second database; and instructing an ingress node of the temporal LSP to signal the temporal LSP in the network along the path computed at a start of the time interval identified in the path request and to tear down the temporal LSP at an end of the time interval identified in the path request.

System for adjusting secured computer resources to handle data transmission from appliances mounted in a vehicle

A vehicle monitoring apparatus (300) transmits transmission data obtained from each appliance (200) and the amount of transmission data to a data processing apparatus (500). First, the data processing apparatus calculates the amount of used resources that is the amount of resources used in processing the transmission data, in the amount of resources of computer resources, on the basis of the amount of transmission data. Next, the data processing apparatus increases or decreases, to the amount of used resources, the amount of secured resources that is the amount of resources secured in the amount of resources of the computer resources. Then, the data processing apparatus processes the transmission data by using the amount of secured resources in the amount of resources of the computer resources.
