Can someone help me with the Steps or Instructions to create a Network Map Server in Corda ?
In the Network Map in Corda docs, I see this can be done in two ways. One with the additional-node-info's which we use the help of Network Bootstrapper, which is clear. And the other HTTP network map protocol is not clear. It would be great if someone shares the steps in detail to create network map server that distributes information across the nodes.
Thanks in advance.
The Cordite Foundation has released an open-source network map implementation: https://gitlab.com/cordite/network-map-service. You can use this as a reference to see how a network map can be implemented.
Because I am not skilled in Kotlin, I use Java to build a simple Corda Doorman and Network Map Service after reading the source codes of Corda and Cordite. You can check them out from Github. Thanks.

I am trying to check the HTTP network map protocol in the sample cordapp example, I have used network bootstrapper to generate node info files. But I need to check the Rest API end points mentioned in the docs: /network-map/publish.
Is it necessary to set up the network map for this? If required,I am not able to get the corda-network map jar file for the community edition. How to access those API endpoints ?
The cordapp samples available in the samples repository uses a locally bootstrapped network. The network bootstrapper is used for this purpose to generate the node-info and the certificates of the network participants. It's a quick and easy way to set up a static Corda network for the purpose of local deployment and testing.
It doesn't have a network map service. The node-info files of each participant is dropped into the additional-node-info folder of the nodes which serves as the network map cache for the node.
The REST end-points you mentioned are available in a real network map service running as part of a dynamic Corda network setup (mostly) used for production deployments.
R3 does not provide a community version of the network map.
However, there is a commercial offering called CENM (https://docs.corda.net/docs/cenm/1.2.html). It's not just a Network Map but also takes care of other aspects of Network Management like Identity and Signing.
In case you are looking for an open-source network map you could try out Cordite Network Map (https://marketplace.r3.com/solutions/cordite-network-map) developed by one of our partners.
I have been try to setup the network map. Where can we get the network-map.jar to run the standalone network mapper for community edition.
Or Network map only comes with enterprise version.
Thanks
There is no community version of the network map provided by R3.
However, as Sneha mentioned there is a commercial offering called CENM (https://docs.corda.net/docs/cenm/1.2.html). It's not just a Network Map but also takes care of other aspects of Network Management like Identity and Signing.
In case you are looking for an open-source network map you could try out Cordite Network Map
(https://marketplace.r3.com/solutions/cordite-network-map) developed by one of our partners.
in open source version, network maps functionality is handled by adding the node-info files to each node's additional-node-infos folder.
If you want to run a stand-alone network map, one option is to use CENM - Corda Enterprise Network Manager. With CENM you get access to the pki-tool, identity manager and network map jars which helps you to set up a private network.

Apart from that if you wish to experiment with a standalone network map, you could also try out a stand-alone network map built by one of our engineers. Pasting the link below

I followed the documentation from docs.corda.net to setup 3 node dev corda network on a single machine.
My goal is to setup multinode production level corda network that involves multiple physical machines. Can someone please help me how can I achieve this?
I want to learn about the corda network capabilities, its different configuration modes etc etc.
I've already setup 3 node dev corda network on a single machine
There are two approaches with which you can achieve the above
Using the network bootstrapper , refer : https://docs.corda.net/network-bootstrapper.html
Using the Network Map Service
For a production level it is preferable to use the network map service as you can manage the nodes dynamically. This is not possible with the networkbootstrapper as the nodes informations are shared within the nodes during the boostrapping which cannot be changed
For NetworkMap Service you can refer Cordite NetwokMapService.
I am new to Nservicebus and have recently started working in it. I am stuck on a point and need input from you guys. I have 2 asp.net core web api projects and I want to use NServicebus to send messages between both of them in some scenarios.
What I have found so far that I can provide name to EndpointConfiguration, what if one of my api is deployed on 1 server and 2nd on another server, in that case how my configuration should be?
I tried to gave url instead of name in EndpointConfiguration but it gave me exception.
Thanks in advance for your help
NServiceBus endpoints communicate over some messaging infrastructure your system will be using. Endpoint names represent queues messages sent to. Messaging infrastructure is abstracted by what NServiceBus is calling a Transport. You will need to decide on the transport you'd like to use (see the options here). Once you've decided what transport your solution will use, you could have a look at the samples for that specific transports to have an idea how to set up your endpoints.
For example, if you'll decide to use Azure Service Bus as your transport, you could download and try the Send/Reply sample.
A good starting point could be the tutorials available on the documentation site here.
I'm working as a student-intern in a govt organization to complete my major-project at college.
My task is to simulate a dynamic-routing protocol for ad-hoc networks. As I've good programming experience in C++ thus I've chosen OMNET++ network simulator.
It was easy to adapt to the working environment and I could play around with the samples provide in OMNET IDE.
Problem Statement:
Now, I need to start working on my task i.e. [ http://www.mediafire.com/?s5ajo8gavhcf6sr ] pls have a look at the paper.
Could someone please give me a few general instructions on building an adhoc network model in omnet and then apply a routing protocol to it.
I would really appreciate if you could just read the abstract of that paper and provide me deeper insights if possible.
Unfortunately your uploaded file is deleted.
So I would suggest to use the INETMANET framework for simulating adhoc network.
There are Manet routing protocols like AODV
You have there Wifi b,g and also 802.15.4 link layers
And there are modules for the whole TCP/IP stack.
