In service flow capability updating in a guaranteed bandwidth multicast network may be provided. First, a node may determine that a bandwidth requirement of a flow has changed to a new bandwidth value. Then, in response to determining that the bandwidth requirement of the flow has changed to the new bandwidth value, an ingress capacity value may be updated in an interface usage table for a Reverse Path Forwarding (RPF) interface corresponding to the flow. The RPF interface may be disposed on a network device. Next, in response to determining that the bandwidth requirement of the flow has changed to the new bandwidth value, an egress capacity value may be updated in the interface usage table for an Outgoing Interface (OIF) corresponding to the flow. The OIF may be disposed on the network device.

A flow tagging technique includes tagging a data flow at a plurality of points in the data flow. For example, the data flow can be tagged at a socket and at a proxy manager API. By tagging the data flow at multiple points, it becomes possible to map network service usage activities to the appropriate initiating applications.

Method and apparatus for facilitating accessing home surveillance device data, preferably an IP camera video stream, by a remote user device at the remote user device's instigation, over the Internet through a home router, the facilitating including incorporating a smart gateway in local communication with the home router and in persistent or intermittent communication with a remote Internet server to facilitate communication of data over the Internet at the remote user device's request through direct communication between the remote user device and the smart gateway, the smart gateway in local communication with the home surveillance device such as an IP camera, the direct communication facilitated by a “hole punch” type of technique.

A method and apparatus where network-layer devices use host-provided, detailed, per-packet, semantic information (DPPS information), which describes the content, meaning, importance, and/or other attributes of particular application data and is associated with each packet, to provide enhanced network services. In some embodiments of the above method, network-layer devices use DPPS information that includes QoS-related information to provide fine-grained, content-aware, and/or complex QoS assurances or similar services. In some embodiments, network-layer devices use DPPS information to provide network-based, application-protocol-independent, rate-adaptation services. In some embodiments, network-layer devices use DPPS information to provide highly efficient, application-protocol-independent, publish/subscribe dissemination services.

Provided are a packet forwarding method based on BIER-TE, a node device and a storage medium. The method includes: acquiring X bit string sub-package structures from a BIER-TE based message; and forwarding the message according to the X bit string sub-package structures, where X is greater than or equal to 1.

According to one embodiment, a control device includes one or more processors. The one or more processors receive a message. The one or more processors determine whether the received message has been replicated and transmitted. The one or more processors instruct recording of difference information between a message before replication and the received message when it is determined that the received message has been replicated and transmitted.

The techniques describe forwarding multicast traffic using a multi-level cache in a network device forwarding plane for determining a set of outgoing interfaces of the network device on which to forward the multicast traffic. For example, a multi-level cache is configured to store a multicast identifier of a multicast packet and multicast forwarding information associated with the multicast identifier, such as identification of one or more egress packet processors of the network device to which the multicast packet is to be sent for forwarding to the set of one or more egress network devices, and/or outgoing interfaces of the network device toward each egress network device of the set of one or more egress network devices. The multi-level cache is also configured to store respective multicast identifiers that are to be encapsulated with outgoing multicast packets that are forwarded to the set of one or more egress network devices.

A system, apparatus, and method for network traffic management. The method includes establishing a building zone corresponding with a physical space in the building, determining how many networked devices are in the building zone, determining a current multicast use level, establishing a virtual group threshold based on a current portion of a network multicast capacity that is being used, and unicast transmitting a message to a plurality of networked devices in the building zone when the number of networked devices in the building zone is less than the virtual group threshold.

One embodiment includes a network device including multiple interfaces to serve as ingress ports for receiving network packets from nodes in remote customer-site network(s) via a tunnel in a provider network, and from nodes in a local customer-site network, and egress ports for forwarding at least some of the network packets, and control circuitry to make a decision to drop a network packet to reduce packet duplication in at least one of the nodes, responsively to the network packet being identified as a packet of broadcast, unknown unicast, or multicast traffic, the network packet being subject to decapsulation of an encapsulation header, being assigned to one of the egress ports, and having a header including one of a plurality of virtual local area network identifications, or one of a plurality of source identifications.

In an aspect, an embodiment of the present disclosure is directed to network control topology that implements a centralized network controller to deterministically assign, and reassign, underlay multicast groups according to one or more policies and/or parameterized intent of the network administrator. The centralized network controller, in some embodiments, comprises a map server-map resolver controller configured to provide deterministic and centralized allocation of LISP underlay multicast groups, e.g., to provide security, traffic engineering, network and resource management.
