A system and method is disclosed of extracting information from real-time network packet data to analyze connectivity data for client devices in a network. The method includes: detecting when client devices initiate a connectivity event; after detecting a connectivity event, waiting a period of time for the client device to either reach or fail to reach a network connected state; after waiting a period of time, recording connectivity event information; and sending the recorded connectivity event information to an analytics system for network incident and/or network congestion analysis.

System and method for using real-time packet data to detect and manage network issues

A system and method is disclosed of extracting information from real-time network data to analyze roaming data for client devices in a network. The method includes: detecting when the client devices initiate roaming association events, buffering other data regarding the detected roaming association events, sending roaming event information to an analytics system for network incident and network congestion analysis, analyzing the roaming event information, identifying one or more root causes of the detected network incidents; and determining remediation of the identified one or more root causes of the detected network incidents.

A system and method for client network congestion analysis and management is disclosed. According to one embodiment, the method includes: collecting real-time network data; executing calculations on the real-time network data to compute performance metrics; detecting peak usage time; and detecting one or more congestion incidents, wherein a congestion incident comprises a persistence of one or more metrics over a time window that comprises detecting a proportion of metric values crossing a threshold that exceeds a defined percentage amount, detecting a time-ordered stretch of metric values that exceeds a defined threshold, or combinations thereof.

System and method for client network congestion detection, analysis, and management

In one embodiment, an apparatus includes a first transport stack, a virtual network interface controller (VNIC), and a second transport stack. The first transport stack is associated with an Internetwork Operating System (IOS), as well as with a plurality of interface-based Internet Protocol (IP) addresses and a plurality of IP addresses. The VNIC is configured to dynamically provision the plurality of interface-based IP addresses and the plurality of IP addresses. The second transport stack is associated with a kernel, and configured to communicate with a first application. The MS is configured to enable the first application to share the plurality of IP addresses and the plurality if IP addresses with a plurality of applications.

Enabling applications in a multi-transport stack environment

In one embodiment, a method includes creating at a network device, a user session with an interactive digital sign, generating a session tag for the user session, wherein the session tag is configured for input at a mobile device, transmitting the session tag to the interactive digital sign, and continuing at the network device, the user session with the mobile device. An apparatus and logic are also disclosed herein.

Transfer of session from interactive digital sign to mobile device

Techniques are presented to enable a network element in a network to receive a request from an application on a device, the request being encapsulated in a packet that includes a header that contains a physical layer identifier of the device to which the application does not have access. The physical layer identifier at the network element may be obtained. A response may be sent to the application on the device, the response containing at least one of the physical layer identifier of the device and location information of the device.

Enabling mobile applications to acquire a MAC address for obtaining location information

Techniques are presented herein for enabling performance monitoring of flows within a management and provisioning tunnel used for communicating packets between a wireless controller and wireless access point devices. A wireless controller that is configured to communicate with at least one wireless access point obtains a packet to be sent to the wireless access point for wireless transmission in a wireless network by the wireless access point. The wireless controller identifies, based on the packet, traffic session flow information associated with the packet. The wireless controller encapsulates the packet with a tunneling header that comprises the traffic session flow information and sends the encapsulated packet to the wireless access point. The tunneling header may also comprise an application identifier (ID) associated with the packet.

Wireless network flow monitoring

In one embodiment, a method includes identifying an access point joining a wireless controller in communication with a switch, establishing a control tunnel between the access point and the wireless controller, transmitting an address of the switch from the wireless controller to the access point, and requesting the switch to setup a data tunnel with the access point. An apparatus and logic are also disclosed herein.

Wireless system with split control plane and data plane

In one embodiment, a licensing authority receives a rehost ticket indicating proof of removal of a license from a first device. The licensing authority receives a request for a license for a second device. The licensing authority validates the rehost ticket to ensure that the license on the first device has been removed from the first device. The licensing authority provides a license for the second device if the rehost ticket is successfully validated, wherein the license that has been removed from the first device and the license for the second device provide the same license capabilities. The first device and the second device are associated with the same customer. Payment has been received for the license associated with the first device but payment has not been received for a separate license capable of being applied to the second device.

Mechanism for secure rehosting of licenses

A method and system for validating a Command Line Interface (CLI) configlet on an image is provided. The method includes creating a parse graph using a plurality of self-describing data constructs, identifying a plurality of parse chain data constructs in the parse graph, deriving at least one CLI/configlet from the image file based on the plurality of self-describing data constructs; and comparing the at least one CLI/configlet derived from the image file with a plurality of CLIs/configlets.

Method and system for validating a CLI/configlet on a given image

A system and method for supporting a 'hitless' switchover from an Active to a Standby processor uses a hybrid synchronization of interface states to allow applications that have been modified to have HA aware features and non-modified applications to function on the system. An interface description data block on the Standby RP is synchronized to the interface description data block on the Active RP and is maintained in a shadow state when the Active RP controls the system. In the event of a switchover between the RPs the interface description data block on the Standby RP is copied from the shadow state to a real state and applications on the Standby RP are notified of a status change.
