隨著時間的推移,網(wǎng)絡通信在過去幾十年里經(jīng)歷了巨大的演進,從簡單數(shù)據(jù)傳輸發(fā)展到今天復雜而高度智能化的體系。這個演進的過程帶來了便利,使得信息傳遞在全球范圍內變得更加高效。然而,隨著網(wǎng)絡的快速發(fā)展,日益增長的網(wǎng)絡流量對性能提出了更為嚴苛的要求。
網(wǎng)絡流量的爆炸式增長,主要受到云計算、物聯(lián)網(wǎng)、高清視頻以及實時應用等因素的推動,使得傳統(tǒng)網(wǎng)絡在應對大規(guī)模數(shù)據(jù)傳輸和實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(Deterministic Networking)成為解決這些挑戰(zhàn)的關鍵。確定性網(wǎng)絡以其獨特的特征和技術,為網(wǎng)絡通信賦予了更高的可預測性和穩(wěn)定性,從而能夠更好地應對當今網(wǎng)絡環(huán)境中的需求。
什么是確定性網(wǎng)絡
確定性網(wǎng)絡的定義
確定性網(wǎng)絡是一種網(wǎng)絡通信體系,旨在提供高度可預測、穩(wěn)定和可控的通信環(huán)境。與傳統(tǒng)網(wǎng)絡相比,確定性網(wǎng)絡通過優(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)絡中的傳輸能夠在預定時間內達到目的地。這種設計使得網(wǎng)絡能夠更好地應對實時通信和對延遲敏感的應用需求。
國內外研究機構及標準化組織已經(jīng)開展了確定性網(wǎng)絡技術的相關研究,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)絡技術應用于工業(yè)控制領域;Internet標準規(guī)范主要的國際標準化協(xié)會組織IETF(Internet Engineering Task Force)成立了確定性網(wǎng)絡工作組,致力于在第2層橋接段和第3層路由段上構建通用架構以建立端到端確定性轉發(fā)路徑。這些研究為確定性網(wǎng)絡的推廣和應用提供了重要的理論和實踐基礎。

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.
