隨著時間的推移，網(wǎng)絡(luò)通信在過去幾十年里經(jīng)歷了巨大的演進(jìn)，從簡單數(shù)據(jù)傳輸發(fā)展到今天復(fù)雜而高度智能化的體系。這個演進(jìn)的過程帶來了便利，使得信息傳遞在全球范圍內(nèi)變得更加高效。然而，隨著網(wǎng)絡(luò)的快速發(fā)展，日益增長的網(wǎng)絡(luò)流量對性能提出了更為嚴(yán)苛的要求。
網(wǎng)絡(luò)流量的爆炸式增長，主要受到云計算、物聯(lián)網(wǎng)、高清視頻以及實(shí)時應(yīng)用等因素的推動，使得傳統(tǒng)網(wǎng)絡(luò)在應(yīng)對大規(guī)模數(shù)據(jù)傳輸和實(shí)時通信方面面臨著一系列挑戰(zhàn)。在這個背景下，引入確定性網(wǎng)絡(luò)（Deterministic Networking）成為解決這些挑戰(zhàn)的關(guān)鍵。確定性網(wǎng)絡(luò)以其獨(dú)特的特征和技術(shù)，為網(wǎng)絡(luò)通信賦予了更高的可預(yù)測性和穩(wěn)定性，從而能夠更好地應(yīng)對當(dāng)今網(wǎng)絡(luò)環(huán)境中的需求。
什么是確定性網(wǎng)絡(luò)
確定性網(wǎng)絡(luò)的定義
確定性網(wǎng)絡(luò)是一種網(wǎng)絡(luò)通信體系，旨在提供高度可預(yù)測、穩(wěn)定和可控的通信環(huán)境。與傳統(tǒng)網(wǎng)絡(luò)相比，確定性網(wǎng)絡(luò)通過優(yōu)化數(shù)據(jù)傳輸路徑、時間敏感的協(xié)議和智能流量管理，以確保數(shù)據(jù)在網(wǎng)絡(luò)中的傳輸能夠在預(yù)定時間內(nèi)達(dá)到目的地。這種設(shè)計使得網(wǎng)絡(luò)能夠更好地應(yīng)對實(shí)時通信和對延遲敏感的應(yīng)用需求。
國內(nèi)外研究機(jī)構(gòu)及標(biāo)準(zhǔn)化組織已經(jīng)開展了確定性網(wǎng)絡(luò)技術(shù)的相關(guān)研究，并取得了一系列重要成果。例如，IEEE與IEC成立了P60802工作組，研究將二層確定性網(wǎng)絡(luò)技術(shù)應(yīng)用于工業(yè)控制領(lǐng)域；Internet標(biāo)準(zhǔn)規(guī)范主要的國際標(biāo)準(zhǔn)化協(xié)會組織IETF（Internet Engineering Task Force）成立了確定性網(wǎng)絡(luò)工作組，致力于在第2層橋接段和第3層路由段上構(gòu)建通用架構(gòu)以建立端到端確定性轉(zhuǎn)發(fā)路徑。這些研究為確定性網(wǎng)絡(luò)的推廣和應(yīng)用提供了重要的理論和實(shí)踐基礎(chǔ)。
With the passage of time, network communication has undergone tremendous evolution in the past few decades, from simple data transmission to today's complex and highly intelligent systems. This evolutionary process has brought unprecedented convenience, making information transmission more efficient on a global scale. However, with the rapid development of the network, the increasing network traffic has put forward more stringent performance requirements.
The explosive growth of network traffic is mainly driven by factors such as cloud computing, the Internet of Things, high-definition video, and real-time applications, making traditional networks face a series of challenges in dealing with large-scale data transmission and real-time communication. In this context, introducing deterministic networking has become the key to addressing these challenges. Deterministic networks, with their unique features and technologies, endow network communication with higher predictability and stability, thereby better responding to the demands of today's network environment.
What is a deterministic network
Definition of Deterministic Networks
Deterministic network is a network communication system aimed at providing a highly predictable, stable, and controllable communication environment. Compared with traditional networks, deterministic networks optimize data transmission paths, time sensitive protocols, and intelligent traffic management to ensure that data can reach its destination within a predetermined time. This design enables the network to better cope with real-time communication and latency sensitive application requirements.
Domestic and foreign research institutions and standardization organizations have conducted relevant research on deterministic network technology and achieved a series of important results. For example, IEEE and IEC established the P60802 working group to study the application of two-layer deterministic network technology in the field of industrial control; The Internet Engineering Task Force (IETF), the main international standardization organization for Internet standard specifications, has established a Deterministic Network Working Group dedicated to building a universal architecture on layer 2 bridging segments and layer 3 routing segments to establish end-to-end deterministic forwarding paths. These studies provide important theoretical and practical foundations for the promotion and application of deterministic networks.
