Dynamically Switched Link Control Protocol

J. D. Young, Alexandra Nicholson · 1992

This memo describes an experimental protocol developed by a project team at Cray Research, Inc., in implementing support for circuitswitched T3 services.The protocol is used for the control of network connections external to a host, but known to the host.It is documented here for the benefit of others who may wish to perform further research.While working with circuit-switched T3 networks, developers at Cray Research, Inc., defined a model wherein a host would generate control messages for a network switch.This work is described in RFC 1306, "Experiences Supporting By-Request Circuit-Switched T3 Networks".In order to simplify the model it was decided that the inconsistencies of switch control should be hidden from the host generating the control messages.To that end, a protocol was defined and implemented.This RFC documents the Dynamically Switched Link Control Protocol (DSLCP), which is used for creation and control of downstream network links by a host. INTRODUCTIONThe Dynamically Switched Link Control Protocol (DSLCP) allows a host with knowledge of a special downstream network link to issue messages to control the status of that link.This document describes the functions of the DSLCP to control external network connections.

Link Aggregation Control Protocol on Software Defined Network

L. D. Irawati, Yuli Sun Hariyani, Sugondo Hadiyoso · International Journal of Electrical and Computer Engineering (IJECE) · 2017

A physical connection of computer network must be made reliably. Breaking connection will cause communication between nodes (for example routers, switches, hosts) can be disconnected. One of the solutions is implemention of link aggregation (LA). LA integrates several of physical ports together to make a single logical communication link. Accordingly, there is load sharing traffic among the member port of the group, high-throughput increasing via a single link, and redundancy providing for broken links. We present the implementation of link aggregation using Ryu controller on Software Defined Network (SDN) topology. The results show that the implementation of SDN with OpenvSwitch and Ryu controller can successfully run link aggregation function to solve the problem of link failure.

Synchronization Control-Plane Protocol for Quantum Link Layer

Brandon Ru, Winston K.G. Seah, Alvin Valera · 2024

Heralded entanglement generation between nodes of a future quantum internet is a fundamental operation that unlocks the potential for quantum communication. In this paper, we propose a decentralized synchronization protocol that operates at the classical control-plane of the link layer, to navigate the coordination challenges of generating heralded entanglement across few-qubit quantum network nodes. Additionally, with quantum network simulations using NetSquid, we show that our protocol achieves lower entanglement request latencies than a naive distributed queue approach. We observe a sixfold reduction in average request latency growth as the number of quantum network links increases. The Eventual Synchronization Protocol (ESP) allows nodes to coordinate on heralded entanglement generation in a scalable manner within multi-peer quantum networks. To the best of our knowledge, this is the first decentralized synchronization protocol for managing heralded entanglement requests.

Survey on Wireless link Reliability Mechanisms using Transmission Control Protocol

Nalin Vimalkumar Subramanian · 2008

Wireless Communication, one of the important demanding technologies basically suffers from unreliable nature due to its high bit error rate caused by handoffs. Transmission Control Protocol, the reliable successful Transport Protocol, basically designed for a wired network handles network congestion effectively. When TCP is implemented over Wireless Network, there will be significant loss due to the unreliable nature of wireless link rather than by congestion. But, TCP implicitly assumes the loss is due to congestion and reacts by invoking congestion control algorithm which degrades throughput, delay, packet discard ratio; finally ending up with inefficient utilization of bandwidth. There are two approaches to handle the situation, either hide the non-congestion losses from TCP sender or differentiate the non-congestion losses from congestion losses. The mechanisms proposed based on the two approaches can be classified into three groups (1) End-to-end protocol, (2) Split Connection protocol, and (3) Link Layer protocol. These schemes are compared and surveyed based on the metrics affecting both Wireless Network and TCP, and a comprehensive report is generated in this survey paper.

IMPROVING XAMKLAB NETWORK BY MEANS OF LINK AGGREGATION CONTROL PROTOCOL

Ulm, Jevgeni · Theseus (Ammattikorkeakoulujen) · 2023

The study was inspired by two situations which hindered lab classes. The first situation was due to the lack of network connection in a classroom. The second situation was due to the lack of bandwidth.
\nThe aim of the study was to improve the network without investing into new equipment. One way to do so was by means of Link-Aggregation Control Protocol. Improving the network lowered the possibility of similar incidents taking place again in the future. This was achieved due to added redundancy and increased bandwidth.
\nThe study researched the link aggregation and its alternatives. The link aggregation was chosen due to being cheapest and the most environmentally friendly of the options. The network was tested, after which, the link aggregation was implemented, and the network was tested again. Test results were recorded and compared.
\nThe study showed that the link aggregation was an effective way of adding redundancy and increasing the bandwidth without any costs resulting in minimal environmental impact.

Radio link control-acknowledged mode protocol performance modeling in UMTS

Nicolas Enderle, Xavier Lagrange · 2003

In this paper, we analyze the performance of the RLC (radio link control) layer in acknowledged mode (AM) in UMTS. In a third generation wireless network like UMTS, the RLC-AM protocol is used to transfer data reliably across the radio access network. With an automatic repeat request (ARQ) mechanism, this protocol is able to provide error correction and in-sequence delivery of IP packets. First, we analytically study the behavior of this link layer when reordering is disabled. Then, we present a simple simulation model for in-sequence delivery, easy to implement and able to capture the main characteristics of the RLC protocol. Theoretical and simulation results are compared in order to prove that a very simple simulation model can behave almost exactly like the RLC layer in UMTS.

A timer-based data link control protocol for mobile computing

Giok Qi Wei, Akihiro Fujii, Y. Nemoto · 2002

We propose a solution to the problem of interconnecting mobile computer to the legacy networks. The Infrared Data Association (IrDA) has suggested the IrDA LAN (IrLAN) network architecture that contains an access point mode, hosted mode, and ad hoc mode; only the access point (AP) mode is considered in this work. The architecture of AP mode is shown. This mode supports mobile computers to access the Internet by access point (AP) equipment. The AP is a stationary equipment containing network interface card (NIC) and IrDA protocol stack; the AP server is used as a router (or gateway) for data transmission. It is clear that the AP mode is a typical usage including both fixed and mobile equipment. As the AP mode expects to be widely deployed, the solution to the power consumption in this mode is significant. Since the current version of the IrDa link access protocol (IrLAP) has a tradeoff between the transmission efficiency and power consumption, the transmission performance will be degraded when implementing electrical power consumption control. To overcome this tradeoff, we propose a timer-based data link control protocol to be a solution specific for the AP mode. The proposed protocol, as a variant of IrLAP, optimizes the power consumption of a mobile host and improves the protocol efficiency during connection establishment and communications. The the problems related to IrDA standards are reviewed, the proposed protocol is given, and the end-to-end protocol performance is evaluated.

Transmission Control Protocol Technique through Congestion Window Control Based on Link Disconnection Awareness

Yongin Jeon, Yunseong Lee, Sungrae Cho · The Journal of Korean Institute of Communications and Information Sciences · 2022

현재 널리 사용되는 전송 프로토콜은 전송 제어 프로토콜(Transmission control protocol: TCP)로 네트워크의 혼잡을 방지하며 안정적인 패킷 전송 및 전송 속도 제어를 제공하기 위해 설계되었다. TCP 통신에서는 네트워크 혼잡에 따라 송신 측에서 단위 시간 내에 보내는 전송률을 제한하여 혼잡에 대응한다. 이에 다양한 혼잡 제어 알고리즘이 다양한 네트워크의 처리량과 대기 시간을 개선하기 위해 제안되었다. 본 논문에서는 상용화되어 운용되고 있는 5G 밀리미터파 대역의 네트워크에서 TCP 송신 측의 트래픽 전송 비율을 조정할 수 있는 혼잡 윈도우(Congestion window: CWND)를 제어하는 기법을 제안한다. 이를 위하여 밀리미터파 특성에서 발생할 수 있는 network failure를 인지하고 이에 따라 CWND을 적절히 조절할 수 있는 알고리즘을 개발하였다. 최종적으로 개발한 알고리즘 성능 평가 단계에서 데이터 처리량이 향상됨을 확인할 수 있다.

An adaptive energy-efficient link layer protocol using stochastic learning control

Siripuri Kiran, R. Chandramouli · 2004

We present a computationally simple stochastic learning control protocol framework for an adaptive energy efficient link layer protocol. A stochastic iterative technique is discussed that can produce soft channel state predictions and track slow/rapidly varying bursty, finite state wireless channels. No piori knowledge about the state transition probabilities is needed for this. Theoretical convergence of the proposed technique is shown. The proposed link layer protocol utilizes the channel state predictions from the stochastic learning algorithm while computing energy efficient transmission policies. This entire process is performed on-line with no pilot (training) symbols, etc., thereby improving the throughput and avoiding energy wastage due to pilot symbols. Simulation results show that up to 50% energy savings can be obtained for some channels when compared with a popular link layer protocol. Energy and delay can be trade-off efficiently using the proposed method.

Radio link control protocol for WCDMA based mobile satellite communication systems

Ki‐Ho Lee, Kyu-Tae Jin, Dong-Ho Cho · 2003

In satellite communication systems, channel capacity is limited because of the limited number of satellites. In particular, uplink channel capacity is relatively low due to low-power handheld terminals, collision of many terminals, and fading by long propagation time. Also long propagation delay limits the number of data-retransmissions for real time traffic, and small capacity limits the number of data-retransmissions for non real time traffic. For these reasons, comparative studies are required in order to identify the most appropriate satellite-based RLC (radio link control) protocol for global mobile multimedia communication via LEO satellite networks. In this paper we consider two kinds of traffic, real time traffic and non real time traffic. For real time traffic, a class of adaptive error-control schemes using both the code rate of FEC and frame length based on the estimated channel state/condition are used as an RLC protocol with transparent mode or unacknowledged mode. Also, for non real time traffic, a hybrid ARQ type II/III protocol is used as an RLC protocol with acknowledged mode.
