Abstract: This disclosure provides for a Layer 4 switching approach wherein a set of L4 switches are organized into a cluster so as to act as a single (or “big”) Layer 4 switch. Connections between the L4 switches are carried out, e.g., using Layer 2 switches. To this end, an intra-cluster routing entity of the switch maintains mapping information (e.g., in a database, or set of data structures) about connections that have been established by the individual switches within the cluster. In this approach, each host (itself a switch) preferably acts like a group of ports of the larger (big) switch. This obviates having each member host from having to maintain connections to many possible destinations. Rather, the intra-cluster routing entity maintains the information about which hosts (and its ports) are connected to which destinations, and the connections are re-used as necessary, even if connections on one side of the “big” switch ceased being used.

Abstract: A method in a mobility management node for handling information in a network. The node is associated with a wireless device being served by a serving network. The node obtains information about that at least one of the serving network and a time zone and a UCI, has been changed for the device, and information about that the change has not been transmitted to a SGW. When at least one of the serving network and the time zone and the UCI, has been changed, and information about the change has not been transmitted to the SGW, the node transmits the information about at least one of the changed serving network and time zone and UCI, to the SGW, enabling the SGW to forward this information to a PGW.

Abstract: The techniques described herein may dynamically adjust the sampling threshold based on a comparison of a flow export rate to a configured flow export rate. Based on the comparison of the flow export rate and the configured flow export rate, the network device may dynamically adjust the sampling threshold, such as increasing, reducing, or not changing the sampling threshold. Moreover, traffic flows are exported based on the adjusted sampling threshold. For example, if a number of bytes of a packet flow is more than or equal to the adjusted sampling threshold, network devices may export the sampled packet flow with the byte count and packet count of the sampled packet flow reported as-is. When a number of bytes of a packet flow is less than the adjusted sampling threshold, the packet flow will be exported with the byte count and packet count adjusted according to a probability.

Abstract: A switching device supports a mixed mode of operation using both layer 2 and layer 3 multicast forwarding tables for multicast forwarding of packets. In the mixed mode of operation the switching device programs multicast forwarding entries in a corresponding layer 2 or layer 3 table depending on a type of protocol to be used for multicast forwarding. The switching device programs multicast forwarding entries in the layer 3 table for multicast packets forwarded using layer 3 routing protocols, and in the layer 2 table for multicast packets forwarded using layer 2 protocols. The switching device converts layer 3 multicast information to layer 2 multicast information before programming multicast forwarding entries in the corresponding layer 2 table.

The first device may provide the traffic using the first information or the second information after storing the first information or the second information.

Abstract: In general, techniques are described for simplifying admission control signaling between subscriber devices, access nodes, and service edge routers to facilitate subscriber-specific admission control for multicast streams. In one example, a service edge router receives a service request and accesses a subscriber profile to determine whether the requesting subscriber is authorized to receive the service. Upon authorization, the service edge router returns the service request to the access node in a substantially similar form in which the service request was received. The access node receives the service request on a service edge router-facing interface, indicating the service edge router has granted authorization for the subscriber device to receive multicast traffic associated with the multicast group identified within the service request.

Abstract: A new approach is proposed that contemplates systems and methods to support file synchronization between a local host and a cloud storage via one or more local content appliances (CAs), wherein each content appliance is a storage device/host configured to locally maintain documents and files previously downloaded from the cloud storage. First, a client agent at the local host discovers and connects to the CA that manage its files locally. To access a file/document that is not cached on its local host, the client agent requests and receives the file from the CA instead of downloading it directly from the cloud storage. When parts of the file are updated locally by the client, the client agent is configured to transmit the updated file to the CA, wherein the updated file is considered as having been fully committed from the client's perspective. The CA then synchronizes with and uploads the revised file to the cloud storage and/or other CAs in the background.
