Information-centric networking (ICN) changes the network’s basic request from “connect me to this host” to “deliver the data with this name.” For data centers, that shift could make data easier to find, cache, replicate, and move—but those are architectural possibilities, not proof that ICN outperforms conventional data-center networks today. A 2012 proposal called IC-DCN offers one concrete design: centralized control with distributed forwarding.
What information-centric networking means
The IRTF’s terminology RFC describes ICN as an evolution from a host-centric network to a data-centric one, “where accessing data by name becomes the essential network primitive.” In a conventional IP exchange, applications typically identify a destination host or service and communicate through a path to it. In ICN, the requested information’s name is central; its location and the route used to reach it need not define its identity. RFC 8793
Named Data Networking (NDN) and Content-Centric Networking (CCNx) are two prominent ICN designs, not names for every possible ICN architecture. In their Interest/Data model, a consumer sends an Interest packet naming content. A matching Data packet returns the requested content. Network elements can potentially satisfy the Interest from a cached copy rather than forwarding it all the way to its original producer.
This model makes in-network caching, replication, and native multicast possible as architectural capabilities. Whether they help depends on the workload and deployment: repeated requests for the same data may benefit from nearby copies, while data that is unique, frequently changing, or difficult to cache may offer less advantage. ICN does not make those benefits automatic.

Why data centers are a candidate
Data centers are a plausible place to explore ICN because applications often need flexible ways to manage and locate data, and a data center is a comparatively self-contained environment in which network changes may be easier to introduce than across the public Internet. That is the rationale behind the Information-Centric Data Center Network (IC-DCN), proposed by Bong Jun Ko and co-authors in a 2012 ACM SIGCOMM ICN workshop paper. Read the IC-DCN paper
How the proposed IC-DCN separates network functions
The paper describes the design this way: “The control-plane is implemented in a centralized manner, while the data-plane is fully distributed.” In practical terms, centralized control would coordinate network decisions, while forwarding would be carried out across distributed data-plane elements. The paper presents this split as a way to combine coordinated management with distributed packet handling; it should be understood as the authors’ proposed architecture, not a description of a standard data-center fabric.

Problems the authors aimed to address
Ko et al. argue that IC-DCN could address data-center concerns such as network scalability and host mobility, alongside ICN-specific challenges including routing scalability, network utilization, and namespace management. These are design goals and claims from the proposal. They do not establish that the architecture has resolved those problems in present-day production networks.
How ICN could be introduced alongside existing networks
ICN does not have to mean an immediate, clean replacement of IP networking. The IRTF’s deployment guidance identifies five configurations: clean-slate replacement, overlay, underlay, network slice, and composite deployment. RFC 8763

| Configuration | How it fits | Practical consideration |
|---|---|---|
| Clean-slate | Replaces the existing network architecture with ICN. | Requires the broadest change to existing applications, services, and operations. |
| Overlay | Runs ICN capabilities over existing network infrastructure. | Can retain the underlying network, but services may need an ICN interface or gateways and protocol mappings. |
| Underlay | Uses ICN as the underlying network, potentially in native ICN islands. | Connecting to wider networks can require protocol-conversion gateways or proxies. |
| Network slice | Provides ICN capabilities in a logically separated portion of a shared network. | Requires decisions about isolation and orchestration alongside integration with existing infrastructure. |
| Composite | Combines multiple deployment approaches. | Integration and operational requirements depend on how the approaches are combined. |
RFC 8763 notes that existing trials primarily use overlay, underlay, and composite configurations. It treats deployment as a staged integration problem: existing services may need gateways or mappings between HTTP/TCP/IP and ICN exchanges, and the approach determines which protocol layers terminate at the network edge. While the RFC discusses data centers as part of the broader network landscape, most of its deployment discussion concerns edge networks, core networks, and content delivery networks.
Questions for evaluating a data-center deployment
- Application compatibility: Can existing IP applications use the ICN service unchanged, or do they need new interfaces or protocol mapping?
- Gateway placement: Where would HTTP/TCP/IP-to-ICN gateways or proxies sit, and which layers would they terminate?
- Forwarding and caching: Which network elements would forward requests or retain cached data, and would the workload create useful cache reuse?
- Isolation and orchestration: If ICN runs as a slice or alongside other network functions, how will it be isolated, monitored, and managed?
- Workload-specific evidence: What measurements show that the chosen design meets the data center’s requirements? The cited RFC and IC-DCN paper do not provide a current, apples-to-apples production performance comparison.
Security: named and signed does not mean confidential
ICN’s data-centric model should not be mistaken for encryption. RFC 8793 says NDN and CCNx generally do not provide data confidentiality; confidentiality is treated as an application-layer concern. Data integrity or signatures, where used, do not by themselves hide content. Applications carrying sensitive information still need suitable confidentiality protections.

What the evidence establishes—and what it does not
The IC-DCN paper is a research proposal published in 2012. RFC 8763, published in 2020, is informational deployment guidance that explains configuration choices and integration concerns. Neither source demonstrates that this specific architecture is widely deployed in modern data centers or that it beats conventional production networking on performance, cost, or reliability.
Accordingly, the sound conclusion is architectural rather than a deployment recommendation: ICN offers a different way to identify and deliver data, and IC-DCN shows how researchers proposed applying that model to data-center networking. Caching, replication, and multicast may be useful in the right workload, but a decision-maker would need evidence from a deployment matching their applications and operational constraints before treating those possibilities as realized benefits.
