摘要:
A virtual network device cluster includes several different virtual network device sub-units, which collectively operate as a single logical network device. The virtual network device cluster identifies the virtual network device sub-unit via which a given packet enters the virtual network device cluster. A packet is forwarded through the virtual network device cluster based on which virtual network device sub-unit has been identified for that packet. In one embodiment, a method involves receiving a packet via a first interface of a first one of several virtual network device sub-units of a virtual network device and associating the packet with the first one of the virtual network device sub-units. The method also involves inhibiting the packet from being sent via an interface of one of the virtual network device sub-units, in response to the packet being associated with the first one of the virtual network device sub-units.

Various methods and systems for detecting whether a network device supports a protocol, which defines a supplemental header, are disclosed. One method involves detecting a value within a preamble generated by a sending device and verifying that a header format of a header, also generated by the sending device, conforms to a header format definition of a protocol. The header format definition of the protocol defines a supplemental header. The preamble can be an Ethernet preamble. In one embodiment, the preamble is a converged data link (CDL) preamble or other type of preamble that is used to convey operation, administration and management (OAM) information.

A virtual network device sub-unit includes an interface to a virtual network device link and a distributed forwarding module. The interface receives a packet, and the distributed forwarding module forwards the packet received by the interface. The distributed forwarding module performs an ingress lookup if the packet includes a multicast destination address and an egress lookup if the packet includes a unicast destination address. If the packet includes a multicast destination address, the distributed forwarding module replicates the packet for each of several outgoing VLANs associated with the multicast destination address. If an additional multicast packet is received via an interface that is not coupled to a virtual network device link, the distributed forwarding module sends at most one copy of the additional multicast packet via the virtual network device link.

An efficient distributed architecture for forwarding packets. The packet to be forwarded arrives in an ingress port, is processed by an ingress forwarding engine, transferred to an egress forwarding engine, and then transmitted via an egress port. An address-based lookup at the ingress forwarding engine identifies the correct egress forwarding engine and also identifies a translation index specifying the forwarding equivalence class (e.g., combination of address prefix and mask) of the packet. The egress forwarding engine then uses the translation index as a memory pointer to recover adjacency information with which to rewrite the packet header. The egress forwarding engine may maintain its adjacency information entirely locally without the need to share the information or propagate updates to ingress forwarding engines. This approach results in a scalable and highly efficient packet forwarding architecture.

A payment processing system for mobile point-of-sale transactions from a mobile point of sale terminal including a payment card reader having a card interface configured to read data from a payment card, the payment processing system includes an automated support system for proactively generating and presenting support messages for merchants using a mobile point-of-sale terminal. The automated support system generates the support message using a current account context for the merchant account and a plurality of rules that indicate a problem with the merchant account. The automated support system is further configured to generate a plurality of rules for detecting merchant account problems using a knowledge database of support tickets that include a human generated response to a merchant account problem and a corresponding merchant account context at the time of the human generated response.

Methods for determining the hardness and/or ductility of a material by compression of the material are provided as a first aspect of the invention. Typically, compression is performed on multiple sides of a geologic material sample in a contemporaneous manner. Devices and systems for performing such methods also are provided. These methods, devices, and systems can be combined with additional methods, devices, and systems of the invention that provide for the analysis of compounds contained in such samples, which can indicate the presence of valuable materials, such as petroleum-associated hydrocarbons. Alternatively, these additional methods, devices, and systems can also stand independently of the methods, devices, and systems for analyzing ductility and/or hardness of materials.

A portable table system includes an article of luggage that has a handle and the handle has a pair of uprights. A table is removably coupled to the handle such that the table may support an object. The table is collapsible such that the table is stored in the luggage. A pair of supports is provided and each of the supports is coupled to the table. Each of the supports is removably coupled to the handle such that the table is retained in a horizontal orientation.

Methods and systems facilitate facilitating notifying a user of potential savings associated with a parts order. According to various implementations, an order file containing order information associated with a first part is received. A determination is made, based on inventory information, that the first part is available from each of a first and second part sellers. Based on a price matrix, a potential cost savings is determined associated with ordering the first part from the first part seller rather than the second part seller, and a savings beacon associated with the part, and indicating the potential savings, is generated and provided to the user.
