Speaking to your Community
Embarking on my journey as a community engineer almost 20 years in the past, I used to be among the many early adopters who acknowledged the transformative potential of community automation. In 2015, after attending Cisco Reside in San Diego, I gained a brand new appreciation of the realm of the attainable. Leveraging instruments like Ansible and Cisco pyATS, I started to streamline processes and improve efficiencies inside community operations, setting a basis for what would develop into a career-long pursuit of innovation. This preliminary foray into automation was not nearly simplifying repetitive duties; it was about envisioning a future the place networks might be extra resilient, adaptable, and clever. As I navigated by means of the complexities of community programs, these applied sciences grew to become indispensable allies, serving to me to not solely handle but additionally to anticipate the wants of more and more subtle networks.
In recent times, my exploration has taken a pivotal flip with the appearance of generative AI, marking a brand new chapter within the story of community automation. The combination of synthetic intelligence into community operations has opened up unprecedented prospects, permitting for even larger ranges of effectivity, predictive evaluation, and decision-making capabilities. This weblog, accompanying the CiscoU Tutorial, delves into the cutting-edge intersection of AI and community automation, highlighting my experiences with Docker, LangChain, Streamlit, and, in fact, Cisco pyATS. It’s a mirrored image on how the panorama of community engineering is being reshaped by AI, remodeling not simply how we handle networks, however how we envision their progress and potential within the digital age. By this narrative, I intention to share insights and sensible information on harnessing the ability of AI to reinforce the capabilities of community automation, providing a glimpse into the way forward for community operations.
Within the spirit of recent software program deployment practices, the answer I architected is encapsulated inside Docker, a platform that packages an utility and all its dependencies in a digital container that may run on any Linux server. This encapsulation ensures that it really works seamlessly in several computing environments. The guts of this dockerized answer lies inside three key recordsdata: the Dockerfile, the startup script, and the docker-compose.yml.
The Dockerfile serves because the blueprint for constructing the appliance’s Docker picture. It begins with a base picture, ubuntu:newest, guaranteeing that each one the operations have a stable basis. From there, it outlines a collection of instructions that put together the setting:
FROM ubuntu:newest
# Set the noninteractive frontend (helpful for automated builds) ARG DEBIAN_FRONTEND=noninteractive # A collection of RUN instructions to put in obligatory packages RUN apt-get replace && apt-get set up -y wget sudo ... # Python, pip, and important instruments are put in RUN apt-get set up python3 -y && apt-get set up python3-pip -y ... # Particular Python packages are put in, together with pyATS[full] RUN pip set up pyats[full] # Different utilities like dos2unix for script compatibility changes RUN sudo apt-get set up dos2unix -y # Set up of LangChain and associated packages RUN pip set up -U langchain-openai langchain-community ... # Set up Streamlit, the online framework RUN pip set up streamlit
Every command is preceded by an echo assertion that prints out the motion being taken, which is extremely useful for debugging and understanding the construct course of because it occurs.
The startup.sh script is an easy but essential part that dictates what occurs when the Docker container begins:
cd streamlit_langchain_pyats streamlit run chat_with_routing_table.py
It navigates into the listing containing the Streamlit app and begins the app utilizing streamlit run. That is the command that really will get our app up and working throughout the container.
Lastly, the docker-compose.yml file orchestrates the deployment of our Dockerized utility. It defines the companies, volumes, and networks to run our containerized utility:
model: '3' companies: streamlit_langchain_pyats: picture: [Docker Hub image] container_name: streamlit_langchain_pyats restart: at all times construct: context: ./ dockerfile: ./Dockerfile ports: - "8501:8501"
This docker-compose.yml file makes it extremely straightforward to handle the appliance lifecycle, from beginning and stopping to rebuilding the appliance. It binds the host’s port 8501 to the container’s port 8501, which is the default port for Streamlit purposes.
Collectively, these recordsdata create a strong framework that ensures the Streamlit utility — enhanced with the AI capabilities of LangChain and the highly effective testing options of Cisco pyATS — is containerized, making deployment and scaling constant and environment friendly.
The journey into the realm of automated testing begins with the creation of the testbed.yaml file. This YAML file isn’t just a configuration file; it’s the cornerstone of our automated testing technique. It incorporates all of the important details about the units in our community: hostnames, IP addresses, system sorts, and credentials. However why is it so essential? The testbed.yaml file serves as the only supply of fact for the pyATS framework to grasp the community it is going to be interacting with. It’s the map that guides the automation instruments to the precise units, guaranteeing that our scripts don’t get misplaced within the huge sea of the community topology.
Pattern testbed.yaml
--- units: cat8000v: alias: "Sandbox Router" sort: "router" os: "iosxe" platform: Cat8000v credentials: default: username: developer password: C1sco12345 connections: cli: protocol: ssh ip: 10.10.20.48 port: 22 arguments: connection_timeout: 360
With our testbed outlined, we then flip our consideration to the _job file. That is the conductor of our automation orchestra, the management file that orchestrates your complete testing course of. It masses the testbed and the Python check script into the pyATS framework, setting the stage for the execution of our automated assessments. It tells pyATS not solely what units to check but additionally check them, and in what order. This stage of management is indispensable for working advanced check sequences throughout a variety of community units.
Pattern _job.py pyATS Job
import os from genie.testbed import load def fundamental(runtime): # ---------------- # Load the testbed # ---------------- if not runtime.testbed: # If no testbed is offered, load the default one. # Load default location of Testbed testbedfile = os.path.be part of('testbed.yaml') testbed = load(testbedfile) else: # Use the one offered testbed = runtime.testbed # Discover the placement of the script in relation to the job file testscript = os.path.be part of(os.path.dirname(__file__), 'show_ip_route_langchain.py') # run script runtime.duties.run(testscript=testscript, testbed=testbed)
Then comes the pièce de résistance, the Python check script — let’s name it capture_routing_table.py. This script embodies the intelligence of our automated testing course of. It’s the place we’ve distilled our community experience right into a collection of instructions and parsers that work together with the Cisco IOS XE units to retrieve the routing desk info. Nevertheless it doesn’t cease there; this script is designed to seize the output and elegantly remodel it right into a JSON construction. Why JSON, you ask? As a result of JSON is the lingua franca for information interchange, making the output from our units available for any variety of downstream purposes or interfaces which may must devour it. In doing so, we’re not simply automating a activity; we’re future-proofing it.
Excerpt from the pyATS script
@aetest.check def get_raw_config(self): raw_json = self.system.parse("present ip route") self.parsed_json = {"data": raw_json} @aetest.check def create_file(self): with open('Show_IP_Route.json', 'w') as f: f.write(json.dumps(self.parsed_json, indent=4, sort_keys=True))
By focusing solely on pyATS on this part, we lay a robust basis for community automation. The testbed.yaml file ensures that our script is aware of the place to go, the _job file provides it the directions on what to do, and the capture_routing_table.py script does the heavy lifting, turning uncooked information into structured information. This strategy streamlines our processes, making it attainable to conduct complete, repeatable, and dependable community testing at scale.
Enhancing AI Conversational Fashions with RAG and Community JSON: A Information
Within the ever-evolving subject of AI, conversational fashions have come a great distance. From easy rule-based programs to superior neural networks, these fashions can now mimic human-like conversations with a outstanding diploma of fluency. Nevertheless, regardless of the leaps in generative capabilities, AI can generally stumble, offering solutions which can be nonsensical or “hallucinated” — a time period used when AI produces info that isn’t grounded in actuality. One solution to mitigate that is by integrating Retrieval-Augmented Era (RAG) into the AI pipeline, particularly together with structured information sources like community JSON.
What’s Retrieval-Augmented Era (RAG)?
Retrieval-Augmented Era is a cutting-edge approach in AI language processing that mixes the most effective of two worlds: the generative energy of fashions like GPT (Generative Pre-trained Transformer) and the precision of retrieval-based programs. Primarily, RAG enhances a language mannequin’s responses by first consulting a database of knowledge. The mannequin retrieves related paperwork or information after which makes use of this context to tell its generated output.
The RAG Course of
The method usually includes a number of key steps:
- Retrieval: When the mannequin receives a question, it searches by means of a database to seek out related info.
- Augmentation: The retrieved info is then fed into the generative mannequin as extra context.
- Era: Armed with this context, the mannequin generates a response that’s not solely fluent but additionally factually grounded within the retrieved information.
The Function of Community JSON in RAG
Community JSON refers to structured information within the JSON (JavaScript Object Notation) format, typically utilized in community communications. Integrating community JSON with RAG serves as a bridge between the generative mannequin and the huge quantities of structured information accessible on networks. This integration will be crucial for a number of causes:
- Knowledge-Pushed Responses: By pulling in community JSON information, the AI can floor its responses in actual, up-to-date info, decreasing the danger of “hallucinations.”
- Enhanced Accuracy: Entry to a wide selection of structured information means the AI’s solutions will be extra correct and informative.
- Contextual Relevance: RAG can use community JSON to grasp the context higher, resulting in extra related and exact solutions.
Why Use RAG with Community JSON?
Let’s discover why one may select to make use of RAG in tandem with community JSON by means of a simplified instance utilizing Python code:
- Supply and Load: The AI mannequin begins by sourcing information, which might be community JSON recordsdata containing info from numerous databases or the web.
- Rework: The information may bear a change to make it appropriate for the AI to course of — for instance, splitting a big doc into manageable chunks.
- Embed: Subsequent, the system converts the remodeled information into embeddings, that are numerical representations that encapsulate the semantic that means of the textual content.
- Retailer: These embeddings are then saved in a retrievable format.
- Retrieve: When a brand new question arrives, the AI makes use of RAG to retrieve probably the most related embeddings to tell its response, thus guaranteeing that the reply is grounded in factual information.
By following these steps, the AI mannequin can drastically enhance the standard of the output, offering responses that aren’t solely coherent but additionally factually right and extremely related to the person’s question.

Conclusion
The combination of RAG with community JSON is a robust solution to supercharge conversational AI. It results in extra correct, dependable, and contextually conscious interactions that customers can belief. By leveraging the huge quantities of obtainable structured information, AI fashions can step past the restrictions of pure technology and in direction of a extra knowledgeable and clever conversational expertise.
