###### Abstract  
The construction of the Industrial Internet has become a concrete implementation and an essential starting point in accelerating the digital transformation and intelligent upgrading of industrial manufacturing enterprises. The problem of addressing and forwarding for resource-constrained devices restricts data acquisition and dissemination on the Industrial Internet. In order to retrieve content reasonably, we propose IDEANE, an identity-differentiated content acquisition and multipath forwarding scheme with network coding and edge computing. In IDEANE, content requests are disseminated based on the identity and location information carried in a multi-identifier network, which can improve the efficiency of interest message requests and reduce idle links in the network. Moreover, the content acquisition computation is offloaded to multiple edge nodes, and the encoded data are transmitted to the edge nodes for recovery. IDEANE offloads the less demanding computing tasks to the edge nodes close to the content requesters, to relieve the pressure on providers. In addition, a collaboration method among multiple edge nodes is also studied. Multiple edge nodes collaborate to support the mobility of content requesters, save energy consumption in terminal devices, reduce transmission latency, and ensure data security. The experimental results show that IDEANE can avoid duplicated transmission, reduce the network link overhead, improve network throughput, and enhance network robustness and reliability.

hierarchical naming scheme in Named Data Networking (NDN, [6]). The forwarding and routing strategy of the data plane principally depends on four tables, namely the content store (CS), pending interest table (PIT), forwarding information table (FIB), and identifier translation base (ITB). End users can employ these tables to look up the local identifier space or search the other identifier spaces with the identifier's mutual translation technology until they find the identifiers that can locate the required content. In addition, they can route and forward what they need in the multi-identifier network with the found identifiers. In order to ensure data security and non-repudiation, MIN-IIoT also carries an identifier of user identity. MIN-IIoT supports adaptive multipath forwarding by introducing CS and PIT structures to record the pending interest messages and returned data messages [7]. In addition, it supports two types of forwarding strategies. One is to choose the optimal route (BestRoute [8]) based on the condition of the current network interfaces. All traffic transmitted on the network will be forwarded through the pre-selected optimal path with the lowest routing cost. Although routing migration can eliminate this problem, routing selection requires much overhead. The other forwarding policy is to actively forward messages in parallel along multiple interfaces provided by the Forwarding Interest Table (FIB), causing the redundancy of content packets brought back by different links. Network coding [9; 10] can take advantage of the in-network cache and multipath transmission of MIN-IIoT; in addition, it can realize the parallel transmission of Industrial Internet data produced by multiple providers on different network links through various communication modes (such as 5G and WIFI) [11]. Cloud, edge, terminal integration, and edge-cloud collaboration represent the major Industrial Internet development trends [12]. Edge gateways and servers near the industrial site can collect, upload, process, and analyze industrial equipment data through edge computing. Edge computing realizes location awareness and determines the equipment location at a relatively reasonable cost. It is convenient to quickly cooperate with the geographic location identifier in the multi-identifier network (MIN-IIoT) to locate Industrial Internet objects.
