  • Patent number: 11330472
    Abstract: Embodiments described herein provide for the pseudo-cooperative load balancing and/or distribution of traffic and/or other types of data by independent nodes. Techniques described herein may be considered “pseudo-cooperative” in that the resulting distribution of traffic and/or other data may resemble load balancing techniques in which various nodes, that serve as an ingress for data for distribution and/or other types of processing, communicate with each other (e.g., share context information) in order to perform load balancing in a coordinated or cooperative manner. In contrast, nodes in accordance with some embodiments described herein may perform load balancing with the same or similar results (e.g., a relatively even distribution of traffic and/or other data), without communicating with each other, thus saving time, processing resources, and/or other resources.

  • Patent number: 11288088
    Abstract: Some embodiments provide novel methods for performing services for machines operating in one or more datacenters. For instance, for a group of related guest machines (e.g., a group of tenant machines), some embodiments define two different forwarding planes: (1) a guest forwarding plane and (2) a service forwarding plane. The guest forwarding plane connects to the machines in the group and performs L2 and/or L3 forwarding for these machines. The service forwarding plane (1) connects to the service nodes that perform services on data messages sent to and from these machines, and (2) forwards these data messages to the service nodes. In some embodiments, the guest machines do not connect directly with the service forwarding plane. For instance, in some embodiments, each forwarding plane connects to a machine or service node through a port that receives data messages from, or supplies data messages to, the machine or service node.

  • Patent number: 11265944
    Abstract: A wireless access node simultaneously serves wireless User Equipment (UE) over Fifth Generation New Radio (5GNR) and Long Term Evolution (LTE). A baseband unit splits user data into a 5GNR portion and an LTE portion per a dynamic 5GNR/LTE split. A 5GNR radio wirelessly transfers the 5GNR portion to the wireless UE. An LTE radio wirelessly transfers the LTE portion to the wireless UE. The baseband unit corrects LTE and 5GNR transmission errors and determines a 5GNR Block Error Rate (BLER) and an LTE BLER. The baseband unit modifies the dynamic 5GNR/LTE split based on the difference between the 5GNR BLER and the LTE BLER. The baseband unit splits additional user data into 5GNR and LTE portions per the modified 5GNR/LTE split.
