This realization&nbsp;of virtual computing resource&nbsp;pooling across the entire network brings advantages, while&nbsp;providing&nbsp;new service delivery capabilities and arithmetic network convergence business models for network operators while improving service quality and resource utilization.<\/p>\n\n\n\n<p>The computational network, i.e., the network infrastructure with the sensing, scheduling and orchestration of computational resources, provides new ICT convergence services of network, computing and storage at the network layer. It represents&nbsp;a new generation of technology architecture and business operation system based on the network.<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Horizontal: intelligent computing&nbsp;at both ends, stateless computing&nbsp;in the middle, intelligent plug-ins perform adaptation between computing&nbsp;applications and network-service&nbsp;computing\/network resources.&nbsp;Computing resources&nbsp;(including storage) are&nbsp;distributed in the edge cloud, edge nodes, such as&nbsp;PE, DC GW. They&nbsp;sense computing&nbsp;states, perform computing&nbsp;scheduling and routing strategy, and intermediate nodes only need to forward according to the scheduled path.<\/li>\n\n\n\n<li>Vertical: The intelligent control plane completes the abstraction of arithmetic sensing, scheduling and orchestration, and the data plane realizes the dual constraints of routing policy arithmetic network and unified protocol architecture planning and execution.<\/li>\n<\/ul>\n\n\n\n<p><strong>Arithmetic network control surface technology<\/strong><strong><\/strong><\/p>\n\n\n\n<p>In&nbsp;the arithmetic network system, the creation of arithmetic routing table requires dynamic sensing of distributed arithmetic, storage and other resource information.&nbsp;The sensing of this information and the corresponding creation of arithmetic routing table are key technologies in&nbsp;the arithmetic network control plane. The arithmetic network control plane&nbsp;can be divided into centralized, distributed and hybrid based on&nbsp;the different mechanisms&nbsp;used for&nbsp;collecting, scheduling and distributing arithmetic resources.<\/p>\n\n\n\n<p><strong>Centralized arithmetic network control surface solution<\/strong><strong><\/strong><\/p>\n\n\n\n<p>In the centralized arithmetic network control plane scheme, the arithmetic, storage and network resources, as well as&nbsp;node information of end, edge and cloud are collected and distributed in a unified manner&nbsp;by the centralized orchestrator . The centralized orchestrator arranges the optimal forwarding and routing paths according to the application requirements, taking account the state&nbsp;of arithmetic and network resources across&nbsp;the entire&nbsp;network, and sends them to the routing&nbsp;and forwarding nodes&nbsp;of the arithmetic&nbsp;network.<\/p>\n\n\n\n<p>The arithmetic resources are distributed and deployed on the network infrastructure, such as&nbsp;edge computing nodes&nbsp;and cloud data centers. The arithmetic resource nodes interact with the centralized orchestrator (or controller) vertically in the north-south direction through the northbound interface.<\/p>\n\n\n\n<p>Applications are accessed from edge nodes, and the centralized scheduler (or controller) needs to orchestrate routing policies based on awareness of the application and its computing power and network requirements. For typical applications, they can be pre-programmed and pre-configured by the centralized orchestrator and pre-delivered to the arithmetic network nodes. The ingress nodes map the applications to the pre-configured paths and route and forward the application traffic accordingly. For atypical applications, the arithmetic network ingress node (or arithmetic gateway) needs to notify the centralized scheduler through the signaling interface, and the latter will arrange and distribute the corresponding policies.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"553\" height=\"277\" src=\"https:\/\/ascentoptics.com\/blog\/wp-content\/uploads\/2023\/05\/image-12.png\" alt=\"Arithmetic Network Control Surface Solution Display Diagram\" class=\"wp-image-118\" srcset=\"https:\/\/ascentoptics.com\/blog\/wp-content\/uploads\/2023\/05\/image-12.png 553w, https:\/\/ascentoptics.com\/blog\/wp-content\/uploads\/2023\/05\/image-12-300x150.png 300w, https:\/\/ascentoptics.com\/blog\/wp-content\/uploads\/2023\/05\/image-12-18x9.png 18w\" sizes=\"auto, (max-width: 553px) 100vw, 553px\" \/><\/figure><\/div>\n\n\n<p><strong>Distributed Arithmetic Network Control Surface Solution<\/strong><strong><\/strong><\/p>\n\n\n\n<p>In the distributed arithmetic network control plane scheme, resource nodes such as arithmetic and storage register (including updating and deleting) their arithmetic resource status information with the arithmetic network nodes nearby.&nbsp;The arithmetic network forwarding and routing edge nodes&nbsp;locally&nbsp;manage the arithmetic node resource information, and the local network-wide notification of arithmetic resource information is realized through distributed routing protocols (IGP &amp; BGP).<\/p>\n\n\n\n<p>The flooding notification of arithmetic resource&nbsp;information&nbsp;by routing protocols&nbsp;will construct a network-wide database of arithmetic resource states within a network domain (e.g., IGP) or between domains (e.g., BGP).
