The network device may determine an amount of retransmission of packets occurring during transmission of the plurality of packets of the data flow.

Abstract: A communication device includes: multiple queues, each of which stores a packet; an input section that inputs a concerned packet to a queue that is among the multiple queues and corresponds to a priority of the concerned packet; an adder that acquires first time when the concerned packet is input to the queue corresponding to the priority, and that adds the first time to the concerned packet; a reader that reads packets from each of the multiple queues in order from a packet with the highest priority; a calculator that acquires second time when the concerned packet is read from the queue corresponding to the priority, and that calculates delay time of the concerned packet from the difference between the first time and the second time; and a priority controller that increases the priority of the concerned packet based on the delay time.

Abstract: A distributed computing system, such as may be used to implement an electronic trading system, controls inbound message flow rates. Limiting a per-client or per-connection inbound message rate also helps ensure fair provisioning of computing resources, so that a single client's excessive use of resources cannot overwhelm the system to such an extent that it prevents other clients from interacting with the distributed system. It is also desirable to have system-wide control of the overall inbound message rate across all client connections. Such system-wide control ensures that the distributed system as a whole can maintain the required levels of service, including offering a predictable level of access for all clients.

Abstract: Methods, systems, and computer programs are directed to the implementation of configurable hierarchical schedulers with multiple levels, where each level may use one of several types of queueing mechanisms. A configurable, hierarchical scheduler is designed to handle large scale processing of requests (e.g., transmitting outgoing messages). The hierarchical scheduler distributes the loads to different queues handling different types of messages (e.g., by user ID, by Internet Address (IP), by schedule). The different layers of the hierarchical scheduler are configurable to queue and schedule traffic based on many factors, such as IP address, handling reputation, available downstream bandwidth, fairness, concurrency rates to handle multiple constraints, scheduling per client, time of delivery constrains, rate limits per user, domain scheduling per user, concurrency throttling per outbound channel, and sharing global rate limits across service processors.

Abstract: A configuration controller (60) is provided to make changes to configuration of a communications network (10) having VNFs used in providing services to UEs. If the change could affect a service using a first VNF (30), if made while that VNF is in use, a substitute VNF (32) is instantiated corresponding to that first VNF.
