摘要:
Hypervisor functions, which may control operations of one or more virtual machines, may be distributed across a plurality of network devices. State information may be stored for the virtual machines on network devices for fault tolerance and resilience. The virtual machines may retrieve stored state information to recover from a fault. The hypervisor may control the storage of the state information. Resources of the network devices may be allocated for fault tolerance and resilience of the virtual machines based on network device parameters, which may include storage capacity, processor usage, access time, communication bandwidth, and/or latency. The state information may include program content, cache content, memory content, and/or register content information, may be stored on a continuous, periodic, or an aperiodic basis, and may be shared among the network devices to enable the processing of data by the virtual machines when a fault occurs, and may be incrementally updated.

Aspects of a method and system for securing a network utilizing IPsec and MACsec protocols are provided. In one or more network nodes, aspects of the invention may enable conversion between Ethernet packets comprising payloads secured utilizing IPsec protocols and Ethernet packets secured utilizing MACsec protocols. For example, IPsec connections may be terminated at an ingress network node and IPsec connections may be regenerated at an egress network node. Packets secured utilizing MACsec protocols may be detected based on an Ethertype. Packets comprising payloads secured utilizing IPsec protocols may be detected based on a protocol field or a next header field. The conversion may be based on a data structure stored by and/or accessible to the network nodes. Aspects of the invention may enable securing data utilizing MACsec protocols when tunneling IPsec secured data through non-IPsec enabled nodes.

A wired and wireless vehicle communication network includes network node modules, switch modules, bridge-routing modules, and a network manager. The network manager is operable to determine a wired packet communication mode and/or a wireless packet communication mode. When the network is in the wireless packet communication mode, the network manager coordinates wireless communication of packets among the network node modules, the switch modules, and the bridge-routing modules based on individual content of the packets and wireless channel mapping. When the network is in the wired packet communication mode, the network manager coordinates wired communication of packets among the network node modules, the switch modules, and the bridge-routing modules based on the individual content of the packets and in accordance with a global vehicle network communication protocol.
摘要:
A network management module includes a network interface module, memory, and a processing module. The network interface module is operable for coupling the network management module to a vehicle communication network. The processing module is operable to manage a global vehicle network communication protocol that includes instituting a content-based network packet processing protocol and managing the vehicle communication network to support the network packet processing protocol. The content-based network packet processing protocol includes determining content type of a packet, determining a processing requirement of the packet, and prioritizing execution of the processing requirement based on the content type.

Network Interface Controller (NIC) logic may receive a packet comprising a routing parameter indicating a service or cost to be utilized in processing the packet. The NIC logic may determine a selected virtual machine (VM) running on a network device to process the packet according to the routing parameter. The NIC logic may communicate the packet across a network after the packet has been processed by the selected virtual VM. Or, the NIC logic may initialize a VM in the network device to process the packet according to the routing parameter. The NIC logic may receive multiple packets and determine a second selected VM or initialize a second VM to process the multiple packets according to the respective routing parameters of the multiple packets. The routing parameters may indicate device capabilities, service class, quality measurements, latency, power usage or any combination thereof.

Communication devices may determine routes and/or may select a route for communicating data between a first communication device and a second communication device. The selected route may require the least power consumption. The determined routes may be ranked based on an amount of power required for routing the data. The data may be routed among devices based on the ranking. Power consumption of a device may be determined based on a bandwidth associated with the device. Route selection may be based on availability of power for power sources of the communication devices. The selection of routes may be based on a current power consumption and/or a history of prior power consumption of the communication devices. The selection of a route which may require least power consumption may be optimized based on the availability of bandwidth.
