In a high speed digital network including access nodes and network nodes each having topology data bases, a method for optimizing the connection set-up operations required for connecting a calling end-user attached to a local access node to a destination user attached to a remote access node, via a conventional connection set-up operation. An Access Node Connection Table (ANCT) in each access node stores a list of every remote access node for which the local access node has at least one user connection. A field in the locate reply message is defined for the destination remote Access Node Topology Database (ANTDB) and remote ANTDB information is inserted prior to sending the reply message. Locate reply message reception is monitored by the local access node, and upon reception an entry is created for the received remote ANTDB information in the local access node unless the remote access node was already identified in the local access node. An optimal path is then selected and connection set up. The ANCT is then updated accordingly.

System and method for maintenance and examination of timers for a computer system having connections in a networking system. Timer values in a connection table each indicate a timeout for a timer for a connection, where each connection has multiple timers, and one of the timer values is written to a global timer array for each connection such that the global timer array can be scanned to determine when timeouts occur for active connections. Sparse restart of a timer includes restarting the timer if data is communicated with a connected computer before the timeout occurs and after a predetermined time interval after timer start, and not restarting the timer if data is communicated before the timeout occurs and within the predetermined interval after timer start.

A switch encapsulates incoming information using a header, and removes the header upon egress. The header is used by both distributed ingress nodes and within a distributed core to facilitate switching. The ingress and egress elements preferably support Ethernet or other protocol providing connectionless media with a stateful connection. Preferred switches include management protocols for discovering which elements are connected, for constructing appropriate connection tables, for designating a master element, and for resolving failures and off-line conditions among the switches. Secure data protocol (SDP), port to port (PTP) protocol, and active/active protection service (AAPS) are all preferably implemented. Systems and methods contemplated herein can advantageously use Strict Ring Topology (SRT), and conf configure the topology automatically. Components of a distributed switching fabric can be geographically separated by at least one kilometer, and in some cases by over 150 kilometers.

An auto-learned hierarchy algorithm that learns the hierarchical layout of a power monitoring system. Historical power data from each meter is received and placed into a data table. The main is assumed to be at the top of the hierarchy and is designated as the reference. A check matrix is developed indicating whether a possible connection exists between each meter pair combination. A correlation coefficient matrix (CCM) is calculated based on the data table, and entries in which no connection is possible are zeroed. The column for the reference meter from the CCM is copied to a correlation reference array (CRA), and the meter having the highest correlation with the reference meter in the CRA is marked as connected to the reference meter in a connection table. That meter's power is subtracted from the data table and the procedure is repeated until all meters have been analyzed.

In one aspect, a database analytical tool or function analyzes join queries to detect queries which could be reduced if a referential integrity relationship were known. In another aspect, a probable latent referential integrity relationship is detected using one or more heuristics. Preferably, a join query is analyzed to detect a joined table which has no other conditions placed on it, and no referential integrity relationship already defined. For any such query, the analysis attempts to verify a probable latent referential integrity relationship using at least one heuristic, such as comparing cardinality of the potential primary key with the size of the table and/or with the cardinality of the foreign key. It is further possible to execute the join for some sample of records, and determine whether any records were found which did not conform to referential integrity constraints.

It is a firewall implementation method that supports the session startup protocol crossover in the field of network security technique. The content is: the firewall analyses the IP division that enters the system. After the IP division enters the system through network interface, the firewall analyses the IP heading information, judges whether the data load is SIP signal information or voice division; the SIP ALG processes the SIP message, SIP ALG analyses SIP message heading to make sure this message belongs to which calling connection. The SIP ALG uses one calling connection state table to track all the calling connection state and modify the content of SIP message heading and/or SDP message according to the information of state table; the firewall processes the down-transferred SIP message from SIP ALG, or performs the instruction issued by SIP ALG, and returns the result to the SIP ALG; according to the result of instruction performing by firewall, the SIP ALG sets or modifies the calling connection table, and sends the SIP message to the firewall, or performs the clearing of calling connection table.

A navigation device has a regional map data item for each of multiple regions, into which a nation is divided. A connection table is included in a regional map data item for a certain region and associates (i) a certain ID of a connection road in the certain region with a certain connection number. The connection road is connected with a paired connection road in an adjacent region. A connection table of a regional map data item for the adjacent region associates an ID of the paired connection road with the same connection number as the certain connection number. When the certain ID in the certain region is replaced with a different ID because of a road construction or the like, only the certain ID is replaced in the connection table with the certain connection number unchanged. This eliminates need of amending the connection table for the adjacent region.

A simplified methodology for accomplishing traffic management in a packet based network is achieved by allowing allocation of bandwidth based on a count of the number of endpoint connections associated with a specific service for a corresponding network device. A network device (e.g., IP router) can be configured to count the number of TCP/IP and UDP/IP connections and bandwidth usage per interface. The counting can be done by identifying the IP Addresses, Type of Service (TOS), and TCP/UDP and/or UDP/IP socket number range in the IP Header of a packet and then querying a specific communication type. When reaching the maximum allowed connections or bandwidth for a specific service, the network device (e.g., IP router) stops forwarding any new calls by means of dropping packets of new calls and informing the given endpoints to disconnect the new calls. In one exemplary embodiment of the invention, a procedure for managing traffic flowing through individual routers of a packet network includes the steps of reserving a given amount of bandwidth on interfaces of the individual routers for specific types of communications traffic, periodically querying endpoint connections based on data from a corresponding router connection table, receiving responses from the periodic querying to determine a current connection status and bandwidth allocation of said endpoints and calculating current bandwidth allocation for a specific type communications service on an interface handled by the router. The router admits additional communications traffic for a specific type of communications service if bandwidth is available.
