摘要:
A network node module within a vehicle operates to manage devices coupled to a vehicular communication network of the vehicle based on a use mode defining rights and privileges for operating in the vehicular communication network. Upon being configured in accordance with a particular use mode of a set of use modes, the network node module can identify a device coupled to the vehicular communication network and enable the device to operate within the vehicular communication network in accordance with the use mode. The network node module is securely reconfigurable to any use mode in the set of use modes.

Aspects of a method and system for traffic management via virtual machine migration include detecting an abnormal traffic pattern in traffic communicated by a first virtual machine that utilizes a first set of network resources. Responsive to the detection of the abnormal pattern, a second virtual machine that utilizes a second set of network resources may be initialized. The second virtual machine may take over functions performed by the first virtual machine and initialization of the second virtual machine is based on an analysis of the traffic. The second virtual machine may be initialized utilizing stored virtual machine sate information in instances that the abnormal traffic is a result of a malicious attack. The second virtual machine may be initialized utilizing current virtual machine state information in instances that the abnormal traffic is not a result of a malicious attack.

Aspects of a method and system for fault resilience in Audio/Video Bridging (AVB) aware Shortest Path Bridging (SPB) networks are provided. In this regard, a path cost, which may be based at least on AVB compatibility, may be determined for each network path discovered between a first network node and a second network node. Additionally, a plurality of network paths may be selected based on the determined path cost, and a plurality of network connections may be established over the selected plurality of network paths. Also, a plurality of data streams may be transmitted and/or received via the established network connections, wherein at least one of data streams comprises data that is redundant to a first data stream. Furthermore, a primary data stream may be conveyed via a first network connection and one or more redundant data streams may be conveyed via a second network connection.

Aspects of a method and system for vehicular power distribution utilizing power over Ethernet in an aircraft are provided. In this regard, one or more circuits and/or processors may be operable to receive supply power that is formatted in accordance with one or more aviation standards, condition the received supply power, and provide the conditioned supply power to one or more electronic components that are communicatively coupled to the Ethernet cable. The one or more circuits and/or processors may be built into and/or mounted on a seat in the aircraft. The one or more circuits and/or processors may provide the conditioned supply power to the one or more electronic components based on a power classification of the one or more electronic components.
摘要:
A method of handling data packets in a network device and an apparatus for handling data packets in a network device are disclosed. The method includes receiving an incoming data packet and the incoming data packet is parsed to obtain a portion of the incoming data packet. That portion is compared with rules stored in a rule table, where each rule specifies a set of actions. A match between the portion and a particular rule of the rules is selected and a particular set of actions, specified by that particular rule is executed. Each rule includes a mask, a selection flag and a validity check that are used in the comparison of the portion with each rule. The rules may be compared with the packet portion serially or in a parallel fashion and if more than one rule matches the portion, the highest priority is selected as the matching rule.

Aspects of a method and system for a centralized vehicular electronics system utilizing Ethernet with audio video bridging are provided. In this regard, electronic devices in a vehicle may be communicatively coupled via one or more Ethernet links and information may be communicated between the electronic devices over the Ethernet link(s) utilizing audio video bridging. At least one of multimedia, control, diagnostic, and sensory information between the electronic devices. Accordingly, resources on the one or more Ethernet links may be reserved via AVB to give priority to one of multimedia, control, diagnostic, and sensory information. Information communicated between the devices may be secured utilizing MACsec and related protocols. The electronic devices may comprise two or more network ports and may be enabled to forward packets between the two or more ports. The Ethernet links may comprise optical and/or copper cabling.
