Managing resource utilization in edge-computing systems

Resource utilization in edge-computing clusters and other computing clusters can be improved according to some aspects described herein. For example, an event handler can detect an event involving a state change to a data object. In response to detecting the event, the event handler can access an event registry storing relationships between a group of controllers and a group of events that are to be handled by the group of controllers. The event handler can determine, using the event registry, a controller that is configured to handle the event. The event handler can then transmit a command over a network to a computing cluster that includes a reconciler associated with the controller, where the command is for causing the reconciler to perform a reconciliation operation with respect to the data object. Separating the event-handling logic from the reconciliation logic in this way may improve resource utilization.

Communication system, communication device, controller, and method and program for controlling forwarding path of packet flow

A communication system includes a communication device controlling packet forwarding, and a controller setting a first table entry used for packet forwarding according to a request from the communication device. The communication device determines whether to forward a received packet according to the first table entry or forward the received packet according to a second table entry set by the communication device based on a rule for identifying a received packet. The load of the controller for controlling paths can be reduced.

Policy control enforcement at a packet gateway

A packet gateway (PGW) receives a plurality of IP packet fragments from a network. The IP packet fragments comprise a head fragment and one or more trailing fragments, and are associated with a first IP packet. As the fragments are received, a controller at the PGW classifies the fragments. The controller applies a same selected service treatment to the head fragment and to each of the trailing fragments based on the classification of the head fragment. The PGW then sends each treated packet fragment to an end user device.

System, method, and computer program product for conditionally restricting an aspect of an electronic message based on the existence of a predetermined data structure

A system, method, and computer program product are provided for conditionally restricting an aspect of an electronic message based on the existence of a predetermined data structure. In use, an electronic message is received. In addition, it is determined whether the electronic message includes a predetermined data structure. Furthermore, an aspect of the electronic message is conditionally restricted based on the determination, for preventing data leakage.

Automotive partial networking apparatus and method

The present invention relates to a automotive partial networking apparatus and method, which operate or terminate only a specific electronic control unit corresponding to a service currently being provided in a vehicle network composed of a plurality of electronic control units. In the automotive partial networking method, a automotive partial networking apparatus receives a partial networking-only Controller Area Network (CAN) frame from outside of the apparatus. A partial network table is searched based on the CAN frame, and then a CAN identification (ID) is searched for. A partial networking-only CAN frame is generated using the CAN ID. Partial networking is performed by transferring the generated partial networking-only CAN frame to at least one electronic control unit corresponding to a vehicle service.

LOOKUP CLUSTER COMPLEX

A packet processor provides for rule matching of packets in a network architecture. The packet processor includes a lookup cluster complex having a number of lookup engines and respective on-chip memory units. The on-chip memory stores rules for matching against packet data. Each of the lookup engines receives a key request associated with a packet and determines a subset of the rules to match against the packet data. As a result of the rule matching, the lookup engine returns a response message indicating whether a match is found. 1. A method of processing a packet comprising:receiving a key request including a key and an identifier (ID), the key including data extracted from a packet;selecting at least one entry in a table indicated by the ID, the entry providing a starting address of a path to a set of rules stored in a memory;processing the entry, based on at least one field of the key, to determine a subset of rules, the subset of rules being a portion of the set of rules;applying the at least one field against the subset of rules; andoutputting a response signal indicating whether the at least one field matches at least one rule of the subset of rules.2.
