摘要： Presented herein are techniques to reduce the number of redirected subscriber packet flows while performing sticky hierarchical load balancing. An Nth head end network element may be activated such that a plurality of N head end network elements are active and capable of receiving and processing one or more packet flows. A primary load balancer may then be directed to overwrite a portion of pointers of a hash table in an evenly distributed manner with pointers to the Nth head end network element such that packet flows are forwarded to the Nth head end network element, wherein the hash table retains a static number of entries as the number of head end network elements is modified.

摘要： Disclosed are systems, apparatuses, methods, and computer-readable media for configuring network groups without software-based processing and management. A method includes: transmitting a topology request from a first leaf node to a first spine node; in response to receiving a network topology reply from a second leaf node, generating a network topology identifying a group of leaf nodes, the network topology reply including network information associated with the second leaf node, and in response to a request to send a message from a first network node connected to the first leaf node to a second network node connected to the second leaf node, transmitting the message to the second leaf node based on the network information from the network topology reply. In some aspects, the first spine node or a second spine node are configured to receive the message and transmit the message to the second leaf node.

摘要： In-band network telemetry for multicast is provided by injecting a synthetic telemetry packet into the multicast. Each first node of each branch replicates the synthetic packet and passes on copy to the next branch and sends one copy down the nodes in the branch sequentially. The synthetic telemetry packet can include flags with have values, including, for example, whether each node should hold or send data collected by the node according to the synthetic data packet, how long a node is to hold collected telemetry data, and what data to collect. The node sends a postcard to the originator with the telemetry data according to the instructions in the synthetic telemetry packet.
