There is disclosed a node for routing data packets in a flow. The node generally comprises a receiver which is configured to receive a command to reroute the flow from a first source route to a second source route. The node also includes a processor for determining that a period of time between first and second consecutive data packets of the flow exceeds a threshold value and a transmitter configured to transmit the second data packet on the second source route in response to the determination. Alternatively, the determination of a period of time between first and second consecutive data packets of the flow can be made by a network controller which can instruct a given node to perform the rerouting of the flow in a manner to route only the second and following consecutive data packets along the second source route.

In general, techniques are described for reducing or otherwise preventing micro-loops in network using Source Packet Routing in Networking (SPRING). In some examples, a method includes detecting a failure of a communication by a network device that implements a Source Packet Routing in Networking (SPRING) protocol to forward network packets using node labels according to an initial network topology. Responsive to detecting the failure of the communication link, the network device may apply, for a defined time duration, one or more adjacency labels to network packets to define a set of one-hop tunnels corresponding to a backup sub-path that circumvents the failed communication link. Upon expiration of the defined time duration, the network device may forward, according to a new network topology that is not based on applying the one or more adjacency labels that define the set of one-hop tunnels, network packets destined for the destination network device.

A packet forwarding system includes: a plurality of first relay apparatuses connected to one another; a plurality of second relay apparatuses that include a plurality of ports and that are connected to the plurality of first relay apparatuses; and a control apparatus that configures a plurality of trunks, each serving as a virtual logical link, by using a plurality of physical links between the first relay apparatuses and the second relay apparatuses. The control apparatus determines a designated port for each of the plurality of trunks from among constituent ports of the each trunk. When one of the plurality of first relay apparatuses receives a predetermined control target packet from one of the plurality of second relay apparatuses, the control apparatus causes the plurality of first relay apparatuses to transmit the predetermined control target packet via a first relay apparatus including a designated port for one of the plurality of trunks, to which a port of the one first relay apparatus receiving the predetermined control target packet belongs.

A system for intelligent multi-device content distribution based on associated internet protocol (IP) addressing, including: identifying, by a computer processor, first advertising content served to a first client device; identifying a first client device IP address associated with the first client device, where the first client device is linked to a household profile; submitting, to a content exchange service, a request for content placement opportunities; receiving content placement opportunities from the content exchange service, where one or more content placement opportunities identify at least a portion of a second client device IP address of a second client device; linking the second client device to the household profile; selecting second advertising content based on the first advertising content; and providing the second advertising content for the content placement opportunity to be displayed on the second client device.

A method, non-transitory computer readable medium, and storage controller computing device that establishes an application interface and a source interface to a programmable switch. A flow table of the programmable switch is updated to insert routing actions associated with the application and source interfaces. Next, when an application request received from an application is locally serviceable is determined. When the determination indicates the application request is not locally serviceable, a migration request for data associated with the application request is sent to the programmable switch from the source interface and a destination address of a source storage server is used. Additionally, a migration response to the migration request including the data from the source storage server is received from the source interface. The data is then stored locally in a destination storage server and thereby is migrated from the source storage server.

A message generation method, a message processing method, a message generation apparatus, and a message processing apparatus are provided. The message generation method includes: obtaining, by a first device, a segment identifier list SID list, where the SID list includes a plurality of segment identifiers SIDs, the first N bits of the plurality of SIDs are the same, and N is a positive integer; generating, by the first device, a first message based on the SID list, where the first message includes a first part and a second part, the first part includes the first N bits of the plurality of SIDs, and the second part includes bit N+1 to bit 128 of each of the plurality of SIDs; and sending, by the first device, the first message to a second device.

A network device may receive, from a source device, an option request that includes a source address of the source device and a destination address of a destination device, wherein the network device is associated with an Internet protocol version 6 (IPv6) network. The network device may identify a map code that is associated with an address translation for traffic associated with the destination device and may determine, based on identifying the map code, a source prefix code and a destination prefix code for the address translation. The network device may determine a source IPv6 prefix and a destination IPv6 prefix for the address translation based on the source prefix code and the destination prefix code and may provide, to the source device, an option response to the option request to permit the source device to use the source IPv6 prefix and the destination IPv6 prefix for the traffic.

Methods and systems are provided for cooperating routers in communication networks. The cooperating routers conduct a handshake to exchange information with respect to “cooperation types” which they are capable of performing and/or are configured to perform. In an exemplary “emergency connection” cooperation type, one cooperating router may use the ISP connection of another cooperating router to send and receive packets. In an exemplary “bandwidth sharing” cooperation type, one cooperating router may make excess bandwidth available for use by other cooperating routers. In an exemplary “latency optimization” cooperation type, one cooperating router may use another cooperating router to transmit duplicates of packets or to implement suppression techniques.

Disclosed herein are systems and methods for recording a routing path within a network packet. In particular, the embodiments provide a mechanism to modify a payload of a network packet to include a hop identifier that uniquely corresponds to the computing device on both a forward path and a return path. The system is configured to return the network packet if an ingress address of the computing device matches a destination address of the network packet. Accordingly, in certain embodiments, a single network packet records in the payload a forward path and return path of the network packet through the network. The solution is inexpensive, simply implemented, and easily executed without relying on new hardware and/or software applications executed at an origin computing device.
