摘要:
A method and apparatus are presented supporting shortest path first (SPF) routing of data packets over a network by establishing link-state data at an router. Link-state data indicates direct links between the router and a different router and establishes an adjacency relationship with the different node. Initial link-state data is stored at a first router. After the initial link-state data is stored, a hello message is received at the first router. The hello message indicates a direct connection with a different second router on one network segment. Based on the initial link-state data, it is determined whether establishing an adjacency relationship with the second router is sufficiently valuable. If not, then an adjacency relationship is not established with the second router in response to the hello message. A shortest path first routing for a data packet traversing the network is determined based on one or more adjacency relationships indicated in link-state data stored at the first router.
摘要:
A method for communicating packets in a network environment is provided that includes communicating, by a first network element, a first summary update to a second network element. The method further includes receiving a second summary update from the second network element. The exchange of the first and second summary updates achieves adjacency between the first and second network elements. The first and second summary updates include, at least, locally generated state information and a single link state.

In one embodiment, a method includes receiving on a first communication link at a local router all routing information at a certain level of detail for each router of multiple routers communicating in a first flooding domain. A measure of distance is determined from a particular router in the first flooding domain to the local router. It is determined whether the measure of distance exceeds a threshold. If the measure of distance exceeds the threshold, then summary routing information with less than the certain level of detail is determined for the particular router. Also, certain routing information is sent over a different second communication link at the local router. The certain routing information includes the summary information for the particular router, and all routing information at the certain level of detail for a subset of routers communicating in the first flooding domain, which subset excludes the particular router.

A method for reducing information being transmitted in a network is provided that includes gleaning routing information being communicated by a first network element, the routing information being stored such that the routing information may be accessed. An adjacency protocol may be executed between the first network element and a second network element that allows for a data exchange between the first and second network elements. The first network element does not communicate the routing information gleaned by the second network element during the data exchange associated with the adjacency protocol.
摘要:
A method and apparatus for sharing routing information include receiving first domain data that indicates domains of a first mobile router. A domain is a collection of routers that share uniform routing information at a particular level of detail. An inbound data packet is received from a second mobile router over a particular link. The inbound control plane packet lists second domain data that indicates domains of the second mobile router. The first domain data and the second domain data together include multiple domains. A particular domain is automatically selected from the first domain data and the second domain data. The second mobile router independently selects the same particular domain. The particular link is assigned to the particular domain; and routing information for the particular domain is shared between the first mobile router and the second mobile router over the particular link.
摘要:
A method for communicating packets in a network environment is provided that includes receiving a packet at a network element and identifying a sequence number included in the packet that correlates to awareness information associated with one or more adjacent network elements. A table included in the network element may be updated in order to account for the awareness information included within the packet that has not been accounted for by the network element. In cases where the awareness information included in the packet has already been accounted for, the packet may be ignored.

A data model that allows for relationships between entities, also referred to as parties, to be modeled as attributes of an entity and for customization of the data model in a manner that facilitates upgrading of the data model. In some embodiments, the data model may facilitate creation and processing of financial applications. Using the data model, received application data can be stored in a financial application record, including data relating to a party's financial statements. In some embodiments, the data model may facilitate management of financial account data for multiple accounts. In some embodiments the data model may facilitate management of credit information, such as credit information collected by credit bureaus.
摘要:
A bicontinuous microemulsion of water, a monomer, and a surfactant copolymerizable with the monomer is polymerized to form a transparent and porous polymer defining interconnected pores. The pores may have a pore diameter in the range of 10 to 100 mm. The microemulsion may further include a drug such that, when the polymer is formed, the drug is dispersed in one or both of the polymer and the pores and is releasable therefrom when the polymer is in contact with a liquid. The drug may be an ophthalmic drug and the polyer can be used to form drug delivery devices, such as contact lenses and artificial corneas.

摘要:
The present invention relates to a piezoelectric micro acoustic sensor based on ferroelectric materials. In one embodiment, more than one electrode pairs are provided within at least one of the central portion and the peripheral portion of a ferroelectric film of the sensor, a polarizing voltage is applied to each electrode pair so that regions of the ferroelectric film between each electrode pair is polarized along the thickness direction, and in a same stress state portion of the film regions of the ferroelectric film between neighboring electrode pairs are polarized in opposite directions, hence the neighboring electrode pairs within the same stress state portion have opposite voltages when the ferroelectric film vibrates. In one embodiment, all of the electrode pairs are connected in series, so that the output voltage of thus connected electrode pairs equals to the sum of voltages of each single pair. Therefore the voltage sensitivity of the piezoelectric micro acoustic sensor is improved significantly.
