Massive Data Connection Architecture Design of Web Platform Based on Blockchain

In order to improve the universality and security of the data management of the Internet of Things and avoid the single point of failure problem in the traditional management architecture, this paper proposes a massive connection management architecture based on blockchain. The blockchain is reconstructed according to the hierarchical structure of blockchain technology, and with reference to the attribute-based access control mechanism, a data exchange model is designed using gossip mode and TLS networking mode to ensure the safe transmission of data. The peer computer network technology, data signature, and consensus mechanism are used to complete the design of the data exchange network layer and realize the design of the blockchain-based massive connection management architecture, so as to effectively avoid the single point of failure problem in the traditional management architecture and greatly reduce the burden of the management center. The access requests of massive devices in 5G application scenarios were simulated, and the results showed that the blockchain-based access control architecture designed in this article can quickly process received requests, with information leakage below 10%, improving the security and processing performance of data connections, achieving efficient processing and management of large-scale data, and providing reliable guarantees for the development of the Internet era.

QoS-guaranteed realtime multimedia service provisioning on broadband convergence network (BcN) with IEEE 802.11e wireless LAN and Fast/Gigabit Ethernet

In broadband convergence network (BcN), heterogeneous broadband wired & wireless subnetworks and various terminal equipments will be interconnected. In order to provide end-to-end realtime multimedia services on such heterogeneous networking environment, as a result, two major problems should be resolved: i) Multimedia session establishment & negotiation that adjusts the differences in the capability of multimedia data processing at the end terminal nodes, ii) quality of service (QoS)-guaranteed connection establishment or resource reservation with connection admission control (CAC) in each heterogeneous subnetworks along the path. The session layer signaling (e.g., SIP/SDP) should be extended for QoS negotiation, and must be tightly cooperating with network layer signaling or resource reservation with CAC function. In this paper we propose a session and connection management architecture for the QoS-guaranteed realtime multimedia service provisioning on BcN, with Q-SIP/SDP, resource reservation protocol with traffic engineering extension, and CAC functions. The detailed interaction scenario and related algorithms for QoS-guaranteed realtime multimedia session, resource reservation and connection establishment are explained and analyzed. From the experimental implementation of the proposed scheme on a small scale BcN testbed, we verified that the proposed architecture is applicable for the realtime multimedia service provisioning. We analyze the network performance and QoS parameters in detail.

A parallel and distributed routing algorithm with a hierarchical connection management architecture for ATM/B-ISDN

In this paper, we propose a parallel and distributed routing algorithm for the ATM/B-ISDN transport networks. In the proposed routing algorithm, a hierarchical connection management architecture is used where each subnetwork has its own connection management functions to find the shortest path for the requested subnetwork connections and the routing information is merged by the upper-level domain subnetwork to find the shortest path in the merged domain of upper-level. This subnetwork routing is performed in each subnetwork in hierarchy, providing maximized parallel and distributed processing capability. The proposed parallel and distributed routing algorithm can reduce the routing and connection setup time in a large-scale network, such as a public B-ISDN.

An ATM-Based Connection Management Architecture forTelecommunications Services

New open service architectures are now emerging. An important part of these architectures is the connection management function. It enables the establishment, control and release of semipermanent connections requested by telecommunications services such as virtual private networks. This paper presents the specification, design and implementation of this connection management function in our OAMS Open Service Architecture. The proposed architecture is deployed over a distributed processing environment.

Scanning the literature

There are inherent difficulties in supporting mobility in ATM networks, due to its connection oriented nature. Once mobile users moves out of certain geographic areas, the ongoing connections for the mobile users have to be rerouted. A suitable connection rerouting schemes must exhibit a number of features including: low handoff latency, efficient routes, minimal disruption to the network traffic as well as the necessary route updates. This paper propose and studies 5 different connection rerouting schemes in ATM-based wireless networks. Extensive experiments show that one of the schemes demonstrates superior performance, seems to be ideally suited for the connection rerouting. This scheme is executed in two phrases, real-time and non-real-time: 1) to execute very fast handoff (reroute) scheme using chaining in a real-time with measured time of 6.5 ms; and 2) reroute the connection in non-real-time to achieve more efficient routes if necessary. The conclusion this paper reaches is that simple handoff schemes coupled with a suitable connection management architecture are sufficient for low-bit-rate multimedia application in the ATM-based wireless networks.

Performance evaluation of connection rerouting schemes for ATM-based wireless networks

Supporting mobility in asynchronous transfer mode (ATM)-based broad-band networks with wireless access links poses many technical challenges. One of the most important of these challenges is the need to reroute ongoing connections to/from mobile users as these users move among base stations. Connection rerouting schemes must exhibit low handoff latency, maintain efficient routes, and limit disruption to continuous media traffic while minimizing reroute updates to the network switches. In this paper we propose, describe an implementation for, and experimentally evaluate the performance of five different connection rerouting schemes. We show that one of these schemes, which operates in two phases, executes very fast reroutes (with a measured latency of 6.5 ms) in a real-time phase and, if necessary, reroutes again in a nonreal-time phase to maintain efficient routing. The scheme also results in negligible disruption to both audio (e.g., a 1-in-100 chance of a single packet loss at CD-quality audio rates of 128 kb/s) and low-bit-rate video (e.g., a 2-in-100 chance of a single packet loss for 1-Mb/s video) traffic during connection rerouting. Based on these results, we conclude that simple handoff schemes coupled with a connection management architecture are sufficient for supporting low-bit-rate continuous media applications over ATM-based wireless networks.

An architecture for managing virtual circuit and virtual path services in ATM networks

ATM networks rely on the Virtual Circuit (VC) and Virtual Path (VP) concepts to provide unicast connection-oriented services with Quality of Service (QoS) guarantees. This paper presents a model for managing the configuration and performance of the VC and VP services in these networks. The model consists of a connection management architecture that provides the services and is instrumented for network management purposes, and a network management architecture that uses the OSI management model to provide access to the appropriate service monitoring and control functions. The network management architecture proposes complete managed object definitions that achieve a variety of monitoring and control objectives: service configuration, service performance at the call and cell level, and service control. The latter includes the capability to establish VPs and control their allocated networking capacity and also control parameters of the signaling system that affect the performance of the VC service. The architecture was implemented in its entirety on the Xunet ATM testbed, and several experiments were conducted to illustrate the trade-off between the throughput of the VC service and the allocation of capacity to VPs. The experiments further demonstrated that the signaling system can create throughput bottlenecks in the absence of VPs in the network, and therefore, the network operator can increase performance by controlling the VP distribution.

The TINA network resource model

TINA, the Telecommunications Information Networking Architecture, is a software architecture for services provided on public and private networks. TINA NRIM adds on the existing concepts and supports a host of new multimedia services that can not be supported by the existing information models. It is expected that network information models will be aligned with those defined by ATM Forum and ITU-T SG15. The authors show a generic information model of network resources, which can be applied to different network technologies. The model contains a number of abstraction levels of network resources. The highest level of abstraction, which is offered at the interface between the network resources and services levels, is defined in terms of a connection graph. The connection graph is an abstract representation of resources describing the connectivity between stream interfaces (media flows). This graph can be used to specify end-to-end connectivity that spans through several layer networks. Thus, a line in the connection graph can be supported by a sequence of trails. The trail, in its turn, consists of subnetwork connections and/or tandem connections. The generic information model with appertained abstraction levels is very well suited to the TINA connection management architecture.
