“…A flat globally unique entity identifier (EID) is used to identify a network entity, and the network address (NA) is used to locate a network entity. When supporting mobility, SEANet uses the enhanced name-resolution system (ENRS) [20] to maintain the mapping between the EID and NA of the mobile consumer and producer. ENRS can provide a deterministic-latency name-resolution service, so the router can quickly resolve and obtain the mapping between the EID and NA of the mobile entities, and use late-binding technology to modify the forwarding path of the packets.…”

Information-centric networking (ICN) separates the identifier and locator of network entities, providing a natural advantage in supporting mobility. To gain the advantage of ICN to support mobility, an urgent challenge is the problem of practical implementation with performance optimization. Software-defined networking (SDN) can be regarded as infrastructure to implement ICN mobility. However, it is difficult for the centralized SDN controller to quickly process mobile signaling. Therefore, this paper proposes enhanced programmable data plane supporting ICN mobility. By offloading mobility-related control plane functions from the controller to the data plane, the data plane can locally process mobile signaling without interacting with the controller. We propose an offloading mechanism for control plane functions, based on a rule table, where the controller authorizes the data plane to process the mobile signaling by loading the programmable rule table to data plane’s control element, and the control element intercepts the mobile signaling, matches the predefined rule table, and executes a series of application logic actions. In addition, we propose an improved SmartSplit algorithm to manage the rule table and speed up packets matching the rule table. Based on Intel’s Data Plane Development Kit (DPDK), we implement the enhanced programmable data plane. Our experimental results prove that the proposed enhanced programmable data plane has a stronger ability to process mobile signaling and reduce latency.

Many bandwidth-intensive applications (such as online live, online games, etc.) are more suitable for using multicast to transmit information. Due to the advantages in scalability, Shared Tree (ST) is more suitable for large-scale deployment than Source-Based Tree (SBT). However, in ST-based multicast, all multicast sources need to send multicast data to a center node called a core, which will lead to core overload and traffic concentration. Besides, most existing multicast protocols use the shortest path between the source or the core and each receiver to construct the multicast tree, which will result in traffic overload on some links. In this paper, we propose an Identifier and Locator Decoupled Multicast approach (ILDM) based on Information-Centric Networking (ICN). ILDM uses globally unique names to identify multicast services. For each multicast service, the mapping between the multicast service name and the addresses of multicast tree nodes is stored in the Name Resolution System (NRS). To avoid core overload and traffic aggregation, we presented a dynamic core management and selection mechanism, which can dynamically select a low-load core for each multicast service. Furthermore, we designed a path state-aware multicast tree node selection mechanism to achieve traffic load balancing by using low-load links more effectively. Experimental results showed that our proposed multicast approach outperformed some other multicast methods in terms of core load, number of join requests, link load, traffic concentration, and routing state.

“…Then, to showed how the hierarchical IP-compatible-ICN cache system works, we designed a specific caching mechanism (As shown in Figure 2) based on an enhanced name resolution system (ENRS) [10,32] with a hierarchical structure, mainly to provide low-latency resolution services for certain delay-sensitive applications, such as 5th generation mobile networks (5G) or mobility support [33]. An ENRS divides an HEA into finer grains by quantifying the transmission latency constraints from the user to the resolution node, which means that the same level HEAs have the same resolution latency and the higher the level of HEAs, the longer the latency is.…”

“…With the assist of resolution nodes (RNs) distributed around the network, deploying an NRS is an effective method to encourage ICN to coexist with the current IP network with high scalability [10]. A hierarchical NRS reduces the inter domain traffic and the latency of naming resolution by keeping the name information of content as close to the user as possible.…”

The major advantage of information-centric networking (ICN) lies in in-network caching. Ubiquitous cache nodes reduce the user’s download latency of content and the drain of network bandwidth, which enables efficient content distribution. Due to the huge cost of updating an entire network infrastructure, it is realistic for ICN to be integrated into an IP network, which poses new challenges to design a cache system and corresponding content router. In this paper, we firstly observed that the behavior pattern of data requests based on a name resolution system (NRS) makes an ICN cache system implicitly form a hierarchical and nested structure. We propose a complete design and an analytical model to characterize an uncooperative hierarchical ICN caching system compatible with IP. Secondly, to facilitate the incremental deployment of an ICN cache system in an IP network, we designed and implemented a cache-supported router with multi-terabyte cache capabilities. Finally, the simulation and measurement results show the accuracy of proposed analytical model, the significant gains on hit ratio, and the access latency of the hierarchical ICN cache system compared with a flat cache system based on naming routing, as well as the high performance of the implemented ICN router.
