Systems and methods can operate to deliver video information over IP networks on a best-effort basis. Best-effort implies that information is delivered without any guaranteed quality of service. During the encoding of video transport streams into video frames, a decoding time stamp (DTS) can be generated that can be used by a video decoder to determine when to begin decoding the video frame data. Information from one or more video frames can be encapsulated in an IP packet. Using the DTS, video encoding rate and video frame size, a time constraint value can be calculated and can provide an indication of the relative transmission priority for the best-effort IP delivery of IP packets containing encapsulated video information.

A flow-driven forwarding strategy includes receiving an Interest packet, where the interest packet includes a flow state indicator. The content associated with the Interest packet is checked to determine whether that content is locally stored. Another check is performed to determine whether any previously received Interest packet has requested the content. In response to the content not being locally stored and no related Interest packet has been previously received, the flow state indicator is checked in the Interest packet. In response to the flow state indicator indicating that the Interest packet is associated with an active flow, forwarding information is extracted from a flow state table if a hop count has a value of zero or from the Interest packet if the hop count has a value greater than zero. The Interest packet is then forwarded to a next hop in accordance with the forwarding information.

In an OpenFlow network, a “proactive type” is attained and hardware (HW) performance problem is solved. Specifically, in the OpenFlow network, each of a plurality of switches executes, on a reception packet that meets a rule of an entry registered in its own flow table, an operation based on an action defined in the entry. A controller registers an entry, in which an identifier unique to a path calculated based on a physical topology of a network composed of the plurality of switches is set as a rule and an output from a predetermined output port as an action, in each of the plurality of switches before communication is started among the plurality of switches.

Example embodiments of the systems and methods of IPv6 mapping disclosed herein involve computing an IPv6 source and/or destination address based on the type of service being used by the user, which is derived from the digits input to the device by the user or system, and the destination phone number input by the user. The mapping is done in second half (for example, 64 bits) of the IPv6 address (the interface ID). The first half of the IPv6 address is a defined subnet (known as a “prefix” in IPv6 terms) for phone number routing. The subnet comprises a global routing prefix and a subnet identification. The interface ID is split into three sections: an identifier, a country code, and an end point number.

A device receives packets of a traffic flow, and inspects one or more of the packets of the traffic flow. The device determines, based on the inspection of the one or more packets, a service graph of feature peers for the packets of the traffic flow. The feature peers are associated with a network, and the service graph includes an ordered set of the feature peers. The device configures network devices of the network with the service graph, and the network devices forward the packets of the traffic flow to the feature peers based on the service graph and without changing the traffic flow.

Some embodiments override network or router level path selection with application or server controlled path selection by repurposing the type-of-service (ToS) or differentiated services header field. A mapping table maps different ToS values to different available transit provider paths to a particular destination. A server generating a packet to the destination selects one of the available paths according to any of load balanced, failover, or performance optimization criteria. The server sets the packet header ToS field with the value assigned to the selected path. A router operating in the same network as the server is configured with policy based routing rules that similarly map the ToS values to different transit provider paths to the particular destination network. Upon receiving the server generated packet, the router routes the packet to the destination network through the transit provider path identified in the packet header by the server set ToS value.

The method further includes, with a second bearer node of the telecommunication component, utilizing network connections between the second bearer node and a second plurality of control nodes of the telecommunication component, the second plurality of control nodes having at least one control node in common with the first plurality of control nodes and at least one control node not common with the first plurality of control nodes.

Technologies for quality of service based throttling in a fabric architecture include a network node of a plurality of network nodes interconnected across the fabric architecture via an interconnect fabric. The network node includes a host fabric interface (HFI) configured to facilitate the transmission of data to/from the network node, monitor quality of service levels of resources of the network node used to process and transmit the data, and detect a throttling condition based on a result of the monitored quality of service levels. The HFI is further configured to generate and transmit a throttling message to one or more of the interconnected network nodes in response to having detected a throttling condition. The HFI is additionally configured to receive a throttling message from another of the network nodes and perform a throttling action on one or more of the resources based on the received throttling message. Other embodiments are described herein.

A tagging mechanism supporting different QoS categories for IP/Port services in a cellular radio network is proposed. Tags are used to differentiate different types of services and corresponding QoS requirements. At the sender side, the sender of the IP packets is able to distinguish different types of services by tagging one or multiple bits for finer QoS control. For downlink IP traffic, the tagging function can be done at the base station. For uplink IP traffic, the tagging function can be done at the UE. At the receiver side, the receiver delivers the IP packets using out-of-sequence delivery for delay sensitive packets. With tagging and out-of-sequence delivery, the delay sensitive packets can reduce CN latency and transmission latency.
