Abstract: Methods and systems are provided for providing secure Ethernet transmissions. In some aspects, an autonomous vehicle system is provided and can include a first system-on-chip being configured to provide data to a second system-on-chip via an Ethernet harness, a first switch being configured to: receive the data from the first system-on-chip, and provide the data to a first transceiver for transmission to the second system-on-chip, the first switch being configured to provide first transmission data to the first transceiver and to prohibit receipt of retrieval data from the second system-on-chip, and the first transceiver configured to communicate with the second system-on-chip via the Ethernet harness.

Abstract: A method and system for providing conditional bandwidth subscriptions to MPLS LSPs. Traffic is policed and/or marked at an ingress node to ensure that traffic that exceeds the LSP's conditional bandwidth is dropped. Traffic above the LSP's committed bandwidth but below the LSP's conditional bandwidth is admitted but marked as suitable for discarding. All traffic below the LSP's committed bandwidth is admitted. A queuing mechanism at each node of the LSP helps ensure that committed bandwidth traffic is protected during periods of congestion. Each node maintains a queue with a first area reserved for periods of congestion and a second area reserved for periods of no congestion. When congestion is encountered, unmarked traffic is stored in the first area and marked traffic is discarded. When no congestion is encountered, both marked and unmarked traffic is stored in the second area.

Abstract: A virtual local area network (VLAN) tunneling system includes an ingress edge switching node that adds VLAN encapsulation information to a packet even if the egress port is configured to act as an untagged 802.1Q port. The packet is tunneled via a label-switched path (LSP) according to a multiprotocol label switching (MPLS) protocol. Label values are used for identifying a next switching node in the LSP to which the packet is to be transmitted. At a penultimate switching node in the LSP, a current label value is replaced with a label value reserved for packets originating from a port associated with a VLAN. An egress switching node in the LSP receives the packet with the reserved label value and recognizes that VLAN information is embedded in the packet. The egress switching node extracts the embedded VLAN information as well as the original source and destination addresses, and processes the packet for transmitting to a final destination.
