Processes for maximizing high-value aromatics production utilizing stabilized crude benzene withdrawal are provided. Aromatic reactor effluent comprising a C5− fraction and a C6 to C10 fraction is separated into a benzene-rich stream and liquid and vapor streams depleted in benzene, one of the liquid streams depleted in benzene being a benzene-depleted C6− fraction. At least a portion of the C5− fraction from the benzene-rich stream is removed.
摘要:
A vibration isolator having a housing defining a fluid chamber, piston assembly, tuning passage, and a switchable fluid path assembly for changing the isolation frequency of the vibration isolator. The piston assembly is resiliently disposed within the housing. A vibration tuning fluid is allowed to flow within the housing. Actuation of a valve in the switchable fluid path assembly selectively controls fluid flow within the fluid path of the switchable fluid path assembly.

A method and apparatus for providing network security using security labeling is disclosed. The method includes comparing first security level information and second security level information, and indicating processing to be performed on the packet based on the comparing. The first security level information is stored in a security label of a packet received at a network node, while the second security level information is stored at the network node.
摘要:
In a virtual infrastructure, a single appliance is provided that hosts a centralized virtual machine monitor (VMM) control plane to effectively establish a single virtual switch across all virtual machines within one or more clusters of servers, thereby reducing the number of management points for the network administrator and facilitating easier VM migration.
摘要:
In providing seamless migration of virtual or physical devices among networks of a virtual local area network (VLAN) such as one spanning multiple data centers, a same virtual anycast Medium Access Control (VMAC) is used for reaching default gateways in virtual and/or physical devices. Each network is typically configured such that source MAC learning for the VMAC should happen only for packets coming from the local default gateway. In this manner, when a device is migrated between networks of the VLAN, the same IP address and corresponding MAC address (typically still residing in the MAC cache of the migrated device) can be used to reach the local default gateway.
摘要:
A crash attenuation system for an aircraft, the system having an airbag carried by the aircraft and inflatable generally adjacent an exterior of the aircraft. The airbag has at least one vent for releasing gas from the interior of the airbag. A first gas source is in fluid communication with the interior of the airbag for inflating the airbag with gas generated provided by the first gas source. A vent valve is provided for controlling a flow of gas through each vent, each vent valve being selectively configurable between an open state, in which gas can pass through the associated vent from the interior of the airbag, and a closed state, in which gas is retained within the interior of the airbag. A second gas source is provided for at least partially re-inflating the airbag after venting of gas through the at least one vent.
摘要:
A system and method is provided for rate limiting network traffic flow of an untrusted application. A master module in a server environment manages network traffic flow restrictions. A slave module executes client applications in the server environment. A services module in the server environment executes a trusted application to validate the client application to the master module. A traffic restriction module on the master module sets network traffic restrictions when validation has not been received for the client application on the slave blade, and receives client application validations from the trusted application to unrestrict network traffic flow for the client application on the slave blade.
摘要:
A method and apparatus for ingress filtering using security group information are disclosed. The method includes performing access control processing on a packet and sending access control information to an ingress node of the packet in response to the access control processing. The access control information includes security group information and an address of a network node. The security group information identifies a security group. The network node is a member of the security group and is a destination of the packet.
摘要:
A method and apparatus for including network security information in a frame is disclosed. Network security information is included in a secure portion of overhead of a frame. The network security information is configured to facilitate network security. A network device configured to process a frame is also disclosed. The frame includes frame security information and network security information. The frame security information is configured to facilitate securing a portion of overhead of the frame, and the network security information is located in the secure portion of the overhead of the frame and is configured to facilitate network security.
