Abstract:
System and techniques are described which apply a method for automatic database schema migration. An initial database is installed, according to rules that define tables of data, in an adaptive private network (APN) having a centralized management system including a network control node (NCN) coupled through the APN to a plurality of client nodes, wherein the NCN provides timing and control to the client nodes. An update to the initial database is received, wherein the initial database includes a first table of data stored in a first set of columns and the updated database includes a modified first table having a second set of columns that has a different number of columns as compared to the first table is automatically detected. One or more columns from the second set of columns that are different than the first set of columns are updated for data content.
Abstract:
System and techniques are described for time correlated playback of traffic patterns between nodes in a network. Node statistics of data transfers between nodes are received in a control point, wherein the node statistics include a time stamp (tn) according to time at the control point of when a request statistics message was sent to each node, a node timestamp (ta) according to time at each node of when the message was received in the node, and a first delta between tn and ta that is used to determine a second delta which adjusts the node statistics. The node statistics adjusted according to the second delta are stored in a statistics database at the control point. A time stepping mechanism is used to repeatedly access the node statistics from the statistics database at a predetermined rate for playback presentation beginning from a specified start time to a specified end time.
Abstract:
Systems, methods, and techniques are described for a display management of an adaptive private network (APN). A database is installed in a first node of a centralized management system including a network control node (NCN) coupled through the APN to client nodes. Timing messages sent by the NCN to the client nodes are time stamped according to a first clock in the NCN. A network time is calibrated in the client nodes based on timestamps of data which are correlated to a master time specified by the first node. The APN is polled for user specified data to be stored in the database, wherein the data is associated with a user specified period of time which is correlated to the master time. The user specified data is accessed from the database for display according to a network configuration, a user selected display type, and attributes selected by the user.

Abstract:
System and techniques are described which provide a method for time correlated monitoring of nodes in a network. A statistics request message is sent from a centralized control point to a node in a network having a plurality of nodes, wherein the statistics request message contains a centralized control point time stamp tn of when the message was sent. The statistics request message is received at the node which records a node timestamp ta when the message was received in the node. Node statistics are converted to system time at the centralized control point according to a first delta between tn and ta to generate adjusted node statistics. A second delta is determined at the centralized control point which is applied to the adjusted node statistics to provide consistent system time information for feedback or presentation through a network attached user interface.
Abstract:
A firewall is described that is integrated in an input stage of a packet processing pipeline so that it recognizes and has access to internal information regarding the different services, such as conduit, intranet, Internet, local vs WAN, applications, and security zones, of a communication network, such as an adaptive private network (APN). The integrated firewall is able to dynamically access the service type, respond to the service type, and adjust the service type based on conditions in the network. Since application awareness and security functions are integrated, customers can set security policies on software applications. The integrated firewall also provides automatic detection of applications, classifies applications based on domain names, steers traffic to services according to software applications, reports on software applications in passthrough traffic, and provides analysis of traffic that does not match a software application so that a user can investigate and define custom applications.
