Hannes Gredler presents applying hyper-scale design patterns to routing. He discusses a multi-level architecture with microservices, commodity hardware, and resiliency. He advocates open source development and cites Cisco's Vector Packet Processing as the best open source routing code. A demo shows a router processing 39 million routes with fast restart times using snapshots for state recovery.

Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

A cellular network, frequently referred to as a mobile network, is a type of communication system that enables wireless communication between mobile devices. The final stage of connectivity is achieved by segmenting the comprehensive service area into several compact zones, each called a cell.

Agenda
I am Hannes Gredler currently exiting my engagement with Juniper Networks, Inc. the worlds second largest router-vendor.
Throughout my entire professional life I have been supporting and building routers and routing software.
It takes 10000 hours of experience to master any art. – In the Routing world I have accumulated experience of
18000 hours of deploying and supporting routers and another 18000 hours for developing software and making system design choices.
At Juniper I am in charge of providing architectural guidance for Junipers Development center in Bangalore, India.
In my role I oversee the routing-protoccol development at the intersection of BGP, IS-IS and MPLS.
As a voluntary community service I do chair the IETF working group standardazing extensions to the IS-IS Link-state routing protocol.
In addition I have authored/co-authored the following documents
http://www.arkko.com/tools/allstats/hannesgredler.html
The core of the system is a distributed data store which holds every state in the system. Irrespective if it is interface information, IS-IS adjacencies, BGP RIBs or forwarding tables – every state is stored in the back store.
Brick Data Store (BDS) it is a model-driven indexing and data replication vehicle.
BDS has been designed for speed and consistency – data insertion can progress as fast as 1M updates per second per CPU core.
The back store is configured by defining tables, objects and its attributes akin to a SQL server using a json config file.
The back store also allows to quickly locate who is the originator of a an object and generate local replicas of that data for local (in-situ) processing.
BDS is fully horizontal scalable, so if there are large tables (like for example RIB-ins) then it can shard the workload across a set of worker processes) all of the shard-ing can happen without changing a single-line of code
The database centric design allows us to do all the cool-HA things, like doing live-software upgrades, restart of components without loss of service, etc. – Furthermore this design paradigm greatly minimizes the amount of boiler-plate code that one has to do to develop new networking code.
