Using design patterns to develop reusable object-oriented communication software

Abstract: Despite dramatic increases in network and host performance, it remains difficult to design, implement, and reuse communication software for complex distributed systems. Examples of these systems include global personal communication systems, network management platforms, enterprise medical imaging systems, and real-time market data monitoring and analysis systems. In addition, it is often hard to directly reuse existing algorithms, detailed designs, interfaces, or implementations in these systems due to the growing heterogeneity of hardware/software architectures and the increasing diversity of operating system platforms.

Network connector operable in bridge mode and bypass mode

Abstract: A hub circuit with an integrated bridge circuit carried out in software including a switch for bypassing the bridge process such that the two bridged networks effectively become one network. An in-band management process in software is disclosed which receives and executes network management commands received as data packets from the LANs coupled to the integrated hub/bridge. Also, hardware and software to implement an isolate mode where data packets which would ordinarily be transferred by the bridge process are not transferred except in-band management packets are transferred to the in-band management process regardless of which network from which they arrived. Also disclosed, a packet switching machine having shared high-speed memory with multiple ports, one port coupled to a plurality of LAN controller chips coupled to individual LAN segments and an Ethernet microprocessor that sets up and manages a receive buffer for storing received packets and transferring pointers thereto to a main processor. The main processor is coupled to another port of the memory and analyzes received packets for bridging to other LAN segments or forwarding to an SNMP agent. The main microprocessor and the Ethernet processor coordinate to manage the utilization of storage locations in the shared memory. Another port is coupled to an uplink interface to higher speed backbone media such as FDDI, ATM etc. Speeds up to media rate are achieved by only moving pointers to packets around in memory as opposed to the data of the packets itself. A double password security feature is also implemented in some embodiments to prevent accidental or intentional tampering with system configuration settings.

Network Management Reconsidered: An Inquiry into Management of Network Structures in Public Sector Service Provision

Abstract: Although policy and collaborative networks have been studied since the 1970s and 1980s, only recently has the management of these entities come under greater scrutiny. Studies of “network management” are designed to better understand the unique challenges of operating in a context where bureaucracy no longer provides the primary tool for “social steering.” These studies typically make three assumptions about networks, public managers, and the tasks of network management that empirical evidence from our casework in “Newstatia” suggests are suspect at best. If so, then network management theory needs to be reconsidered. The second half of this article begins this process. We have organized this article into six sections. The first defines policy and collaborative networks and discusses why analyzing them and their management independently is probably flawed. The second presents our data and justifications for believing the assumptions outlined above are oversimplifications. The third section reviews three perspectives and two partial models of network management and points out how the perspectives and models need integration. The fourth section develops a resource dependence framework for network management that can encompass the existing models and our new data on the environment in which network management occurs. The final section outlines a series of propositions that flow from our reconsideration of network management.

Supporting IoT With Rate-Splitting Multiple Access in Satellite and Aerial-Integrated Networks

Abstract: To satisfy the explosive access demands of Internet-of-Things (IoT) devices, various kinds of multiple access techniques have received much attention. In this article, we investigate the multicast communication of a satellite and aerial-integrated network (SAIN) with rate-splitting multiple access (RSMA), where both satellite and unmanned aerial vehicle (UAV) components are controlled by network management center and operate in the same frequency band. Considering a content delivery scenario, the UAV subnetwork adopts the RSMA to support massive access of IoT devices (IoTDs) and achieve desired performances of interference suppression, spectral efficiency, and hardware complexity. We first formulate an optimization problem to maximize the sum rate of the considered system subject to the signal-interference-plus-noise-ratio requirements of IoTDs and per-antenna power constraints at the UAV and satellite. To solve this nonconvex optimization problem, we exploit the sequential convex approximation and the first-order Taylor expansion to convert the original optimization problem into a solvable one with the rank-one constraint, and then propose an iterative penalty function-based algorithm to solve it. Finally, simulation results verify that the proposed method can effectively suppress the mutual interference and improve the system sum rate compared to the benchmark schemes.

Geospacial internet protocol addressing

Abstract: The invention provides for conversion of latitude and longitude to an addressing scheme that supports current TCP/IP (v4) and future addressing (v6/ng) requirements. More specifically, it allows a decentralization of the unicast point to device on the hosted network. Geographical Internet Protocol (GeoIP) addressing will facilitate any cast routing schemes where the nearest node has a statically assigned GeoIP. Geo routing, and network management become a function of the GeoIP address.
