Abstract: Techniques are described for multicast flow prioritization in protocol independent multicast (PIM) networks with multicast flow limits. According to the disclosed techniques, once a router has reached its multicast flow limit, the router may preempt an installed lower priority multicast flow with a newly requested higher priority multicast flow. For example, if a maximum number of multicast flows are installed on the router, then, upon receiving a PIM join for a higher priority flow as compared to the installed flows, the router replaces one of the installed lower priority flows with the received higher priority flow. Furthermore, according to the disclosed techniques, priority values for multicast flows are consistent across a PIM domain and each of the routers within the PIM domain is configured to use the priority values to select a higher priority flow over a lower priority flow.

Abstract: Some embodiments provide a method for a first managed forwarding element operating within a first data compute node (DCN) that executes on a host machine. From the first DCN, the method receives a packet destined for a second DCN that is logically connected to the first DCN through a set of logical forwarding elements of a logical network.

The method forwards the packet to the second managed forwarding element.

Abstract: Low-cost network switches and other computing systems are described herein. A low-cost network switch can operate at a lower ambient temperature (e.g., 55° C.) than conventional switches, thereby enabling the use of lower cost components (e.g., optical components that are not rated for operation at up to 70° C.). The network switch can utilize a power bar pass-through card that provides power from an enclosure bus bar to components of the network switch in lieu of a power supply unit. Additionally, ports of the network switch can operate in a 2×50G mode in which a network switch port capable of communicating at 100 Gbps interfaces with two external ports each capable of communicating at 50 Gbps. Communication in 2×50G mode can be supported by a four-channel Y-cable, in which the four channels are utilized by the network switch port and fan-out to two channels to each of the two external ports.

Abstract: To more efficiently utilize buffer resources, schedulers within a traffic manager may generate and queue read instructions for reading buffered portions of data units that are ready to be sent to the egress blocks. The traffic manager may be configured to select a read instruction for a given buffer bank from the read instruction queues based on a scoring mechanism or other selection logic. To avoid sending too much data to an egress block during a given time slot, once a data unit portion has been read from the buffer, it may be temporarily stored in a shallow read data cache. Alternatively, a single, non-bank specific controller may determine all of the read instructions and write operations that should be executed in a given time slot. The read instruction queue architecture may be duplicated for link memories and other memories in addition to the buffer memory.

Abstract: User equipments (UEs) can be efficiently clustered into groups of UEs where a UE of a group can be selected as a host UE to communicate with a radio access network (RAN) on behalf of other UEs in the group. A resource manager component can receive information, including predictive information of predicted future UE performance or characteristics, relating to respective power availability, signal strength, data performance, and transit vectors of respective UEs from UEs in an area, and determine which UEs are to be clustered in a group and which UE(s) of the group is to be a host UE(s) for the group based on such information. The host UE can facilitate communications between the other UEs in the group and the RAN. The resource manager component also can employ a round-robin technique for substantially equal sharing of duties as host UE among multiple UEs of the group.
