Description:
Networks are moving toward simplification, increased operational efficiency, and programmability using technologies such as software-defined networking. Cisco continues to demonstrate innovation by introducing the concept of segment routing in the data center, making the network more intelligent and adaptive to the applications running on top of it. Segment routing delivers application-optimized network transport. Encoding the path information directly at the source (that is, either at the virtual switch or at the top of rack) and using per-app policies, segment routing puts control in the hands of the network operators by empowering them to create secure, adaptive, and optimal paths based on the requirements of the application itself.
Please join us in the session to learn how Cisco is helping organizations increase network efficiency by allocating resources on demand and optimizing the network to better support business-critical applications, all while preserving security.
Agenda
Topics to discuss include:
- Introducing segment routing
- Why the need for application-optimized transport
- Features and benefits of segment routing
- Differences between segment routing and MPLS transport
- Relevance of segment routing in the data center
- Use cases and applicability of segment routing
- Summary and conclusion

Daniel Firestone and Gabriel Silva's presentation from the 2017 Open Networking Summit.
SDN is at the foundation of all large scale networks in the public cloud, such as Microsoft Azure - at past ONSes, Microsoft has detailed how all of Azure's virtual networks, load balancing, and security operate on SDN. But how do we make a software network scale to an era of 40, 50, and 100 gigabit networks on servers, providing great performance to end customers with ever increasing VM and container scale and density?
In this presentation, Daniel Firestone and Gabriel Silva will detail Azure Accelerated Networking, using Azure's FPGA-based SmartNICs. They will show how using FPGAs, we can achieve the programmability of a software network with the performance of a hardware one. They will detail how this and other host SDN advances have led to huge performance increases for Linux VMs in particular, and Linux-based NFV appliances, giving Azure industry-leading network performance.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

3. What is an IXP?
Any place
where
providers
meet to
exchange
traffic.
ISP-06
ISP-02
ISP-05
ISP-03
ISP-01
ISP-04
IXP Switch
4. Why it is needed?
• IXPs help reduce the portion of an ISP's traffic that must be delivered via their
upstream transit providers, thereby reducing the average per-bit delivery cost of
their service.
• IXPs play an essential role in reducing the cost of transit connections over the
Internet.
6. To ReachThe Destination……
• Study – historical data to get the idea of NIX Operation
• Observation- others NIX to get the GraphicalView of a NIX.
• Plan – what we would like to do and how.
• Deployment – begin the journey towards the Goal.
• Challenges – what we have faced.
• Initiatives – to overcome those challenges what we have
done.
• Configuration – what changes we have made.

11. How Challenges we have faced during the “Route Server” Deployment
- Route Server Selection: Router or Linux Server
- “Open source” Routing daemon Selection:
• BIRD
• GoBGP
• OpenBGPd:
• FRR (fork of Quagga)
• Quagga (LINX fork)
BIRD is used in several Internet Exchanges, such as the London Internet Exchange (LINX), LONAP,
DE-CIX and MSK-IX as a Route Server, where it replaced Quagga because of its scalability issues.
- BIRD Version Selection:
- Version 1.6, 1.7, 2.0.7, 2.0.8, 2.0.9, 2.0.10 (27.6.2022 - New release)
12. Why we select BIRD Version 2.0.9?
• BGP: Flowspec validation procedure
• Babel: MAC authentication support
• CLI: New 'show route in <prefix>' command
• Filter: Faster (16-way) prefix sets
• Filter: MPLS label route attribute
• Filter: Operators to pick community components
• Filter: Operators to find minimum and maximum element of lists
• BGP: Log route updates that were changed to withdraws
• BGP: Improved 'invalid next hop' error reporting
• OSPF: Allow ifaces with host address as unnumbered PtP or PtMP ifaces
• OSPF: All packets on PtP networks should be sent to AllSPFRouters address
• Scripts for apkg-powered upstream packaging for deb and rpm
• Support for Blake2s and Blake2b hash functions
• Security keys / passwords can be entered in hexadecimal digits
• Memory statistics split into Effective and Overhead
• Linux: New option 'netlink rx buffer' to specify netlink socket buffer size
• BSD: Assume onlink flag on ifaces with only host addresses
• Many bugfixes

21. Major Challenges What We have faced for SIPIX
Challenges:
- Unlimited concurrent calls.
- Minimum Call SetupTime.
- Ensure HighVoice Quality all time.
- Ensure High Availability
22. What Initiatives we have taken against the Challenges
Unlimited concurrent calls is depends on No. of Cores & RAM.
I have allocate more Core and RAM for the SIPIX Server as required.
Minimum Call SetupTime is depends on Optimized Routing.
We have worked to do the same as required.
To Ensure HighVoice Quality all time, We have provided G711 Codec.
To Ensure High Availability, we are working for the same.
23. Root Servers
Root Servers are responsible for directing each domain name
lookup request to its respective nameserver.
25. Root Server Anycast Instances Deployment
Deployment Challenges:
1. Meet the Requirements of the Operators for the ROOT Instance.
2. Availability of the Equipment's as need for deployment.
3. Deployment Plan for the Anycast Root DNS for the Specific Region.
Initiatives for the Deployment:
1. We have communicated with Some DNSOperator for the Anycast Root Instance
Deployment.
2. After getting the green signal from the operator, we have provided the required
information.
3. Hope that, we will get the Root Server instance with in short possible time.
