    Abstract: A system may receive network device configuration information associated with a network service. The system may determine multiple settings associated with the network service based on receiving the network device configuration information. The multiple settings may include a common setting and a device-specific setting. The system may generate a first network service model of the network service based on the multiple settings. The first network service model may include multiple nodes corresponding to the multiple settings. The system may re-configure one or more nodes associated with the first network service model, and may generate a second network service model of the network service. The system may generate a user interface template based on the second network service model and may provide the user interface template to a client device for display. The client device may allow a configuration of the multiple settings based on the user interface template.

  • Patent number: 10270604
    Abstract: Techniques are described for grouping related flows using a flow attribute value indicated by a modified protocol independent multicast (PIM) join request. According to techniques of this disclosure, a network device is configured to receive, from a downstream network device, two or more first PIM join requests indicating two or more multicast groups. In response to determining that each first PIM join request of the two or more first PIM join requests indicates a common first flow attribute value, the network device is configured to select a common path. The network device is further configured to send two or more second PIM join requests indicating the two or more multicast groups to an upstream network device along the selected common path and toward the source. Each second PIM join request of the two or more second PIM join requests includes a common second flow attribute value.

  • Patent number: 10263896
    Abstract: In some embodiments, an apparatus includes a gateway device that can be operatively coupled to a switch via a set of links. The gateway device can operatively couple a network node during a communication session with the switch, and can store an association between the communication session of the network node and a link such that data sent via the communication session of the network node is sent via the link. In such embodiments, the gateway device can receive, from a virtual port associated with the network node, a login request. The gateway device can send the login request to the switch to initiate a communication session between the virtual port and the switch. The gateway device can also associate the communication session of the virtual port with the link based on the communication session of the network node being associated with the link.

  • Patent number: 10257074
    Abstract: Techniques are described for avoiding traffic loss in a network when a designated router (DR) for a L2 broadcast communication domain loses its route toward a multicast traffic source. The disclosed techniques may be utilized in a scenario where a receiver is multi-homed to a DR network device and a non-DR network device by a L2 broadcast communication domain. Both the DR and the non-DR network devices receive a request from the receiver identifying a multicast group in which the receiver is interested. The non-DR network device monitors traffic injected into the L2 broadcast communication domain by the DR in order to determine whether the DR has lost the route to the source of the multicast group. If the DR has lost the route, the non-DR network device performs a repair by sending the multicast data traffic for the multicast group to the receiver on the L2 broadcast communication domain.
