2. Introduction

3. Overview
● In a distributed environment comprising of a large number of nodes, the demand
for efficient communication increases.
● Conventional communication methods, such as those based on Internet Protocol
(IP), may result in an excessive exchange of messages among network nodes,
ultimately degrading network performance.
● So, to enhance communication efficiency among network participants, we
implement an Information Centric Networking (ICN) architecture, particularly
Named Data Networking (NDN).

4. Named Data Networking (NDN)
● The traditional IP-based Networking relies on delivering data to a given
destination address based on their IP addresses.
● Named Data Networking does not deliver packets to a given destination
address (IP), rather it fetches the data, identified by a given name, cache it
into local Content Stores, for immediate use.
● It works on the principle of multicasting, as it aggregates the number of
similar interests in the Pending Interest Table.

6. NDN Router Components
● Content Store (CS): Stores data packets temporarily to serve immediate
requests, reducing latency and traffic congestion.
● Pending Interest Table (PIT): Stores unfulfilled interest packets, ensuring
that consumers receive the requested data.
● Forwarding Information Base (FIB): Similar to a routing table, it helps NDN
nodes decide how to route packets efficiently.

8. Literature Review

9. BlockNDN (Jin et al., 2017) [3]
● Key Findings
○ Presented a bitcoin-based decentralised ledger system running on NDN
architecture.
○ Utilised the ChronoSync method for data fetching.
● Research Gaps
○ Focussed on the theoretical comparison between IP and NDN based
networks, rather than performance of the system.
○ Not so efficient because number of transmissions are less.

10. BoNDN (Guo et al., 2019) [4]
● Key Findings
○ Resolved the compatibility issue between blockchain and NDN.
○ Enabled deployment of blockchain applications over NDN.
● Research Gaps
○ Utilised the Subscription-push approach, which requires the use of an extra
table known as Subscription Push Table (SPT).
○ It led to an increased space complexity of the system.

11. DLedger (Zhang et al., 2020) [5]
● Key Findings
○ Presented an IoT-friendly distributed ledger in private business scenarios.
○ Utilized Directed Acyclic Graph and Proof of Authorization protocols in
blockchain, over NDN architecture.
● Research Gaps
○ IoT specific, private network.
○ Focussed mainly on blockchain more than the networking paradigm.

12. Objectives
❏ Conduct in-depth analysis of NDN architecture and compare performance metrics
with IP-based networking.
❏ Implement and integrate NDN data dissemination protocol within blockchain
architecture.
❏ Test the NDN-Blockchain architecture on custom made topology.
❏ Evaluate key performance and compare the results of our blockchain with that of
IP-based.

13. Proposed Work
● We suggest a block delivery method employing an Announce-Pull mechanism for
data propagation.
● The core idea is to use a gossip-like protocol for peer-to-peer communication to
multicast the announcement of new data.
● Once peers are informed about the announcement, they can retrieve the data block.
● Uniquely naming the data allows redundant requests to be aggregated.
● Returning data packet can be cached by the network in the nearby routers.
