Software Defined to Spatial Defined Networking

While software defined networking has proven its value, SynchroKnot has taken software defined networking to a whole new dimension with Spatial Defined Networking.

Spatial Defined Networking is made up of SynchroKnot’s core networking component called Satellite Tree Protocol, which is an enhancement to the IEEE standard [ 802.1D (1998|2004), 802.1W ] while keeping the core semantics in place.

This simplistically means, you can use any commodity X86_64 Desktop/Workstation/Server/Embedded device and connect them to eachother.

There is no need to purchase physical or virtual switches and routers or any of their licenses [Eg. Cisco, Juniper etc].

Satellite Tree Protocol is the core networking component of the SynchroKnot Cloud Computing and Data Center Decentralization software.

In brief, the SynchroKnot software transforms any server, workstation, desktop or embedded device into a decentralized cloud or data center [data decenter].

There are various demonstration videos depicting its workability, performance, security and scalability on synchroknot.tokyo

Here are some of the highlights of the SynchroKnot Satellite Tree Protocol:

■ Automatic – Mission-Critical – Resilient – Self-Sustaining – Self-Healing – Seamless Scaling Without Down-Time – High-Performance.

■ Nothing to configure or manage.

■ Enhancement to the IEEE standard [ 802.1D (1998|2004), 802.1W ] while keeping the core semantics in place.

Standard Layer 2 Ethernet remains pure, untouched and unmodified without frame encapsulation, additional headers or other forms of tinkering.

■ Improving upon and applying the globally accepted IEEE standard found in network switches onto Spatial Fabric Satellites. Network is no longer a separate complex component with separate hardware and licenses, but is now built right in with nothing extra that needs to be done.

■ Depending on your need and/or requirement, you now have a logical straight-forward option and ability to eliminate Top-of-the-Rack, Spine, Leaf, Edge, Aggregation and Core Switches & Routers, along with their respective licenses.

■ Large-Scale, High-Performance Layer 2 Environment with a single instance of Satellite Tree Protocol with support for single, double and triple stacked VLANS.

■ Does not cause a network-wide outage on failure of link(s) as experienced with regular Spanning Tree Protocol [ STP ] and Rapid Spanning Tree Protocol [ RSTP ].

■ Recovery from failure is, in most cases, in sub-milliseconds to about 1.5 seconds depending on the nature of failure [ single / multiple links ] and the distance from the point(s) of failure. Traffic that does not traverse the path where failure occured is generally not affected by the failure at all.

■ Intelligent Layer 2 Optimized Cost Multipath forwarding logic based on local intelligence chooses the best link with the shortest optimal path in normal operation, congestion and on link failure.

■ Multiple ANY-to-ANY Layer 2 routes allow you to add and remove hardware transparently without turning off whole or sections of the network, as experienced with switches and routers in networks today.

■ Zero Configuration.

How about never having to endure countless hours of pain configuring, managing and maintaining physical Ethernet ports, trunking and ACLs and other aspects? How about plugging one end of Ethernet cable into ANY physical port of a commodity hardware and connecting the other end to ANY physical port of another commodity hardware and that’s it – nothing to do.

■ Get the best of cost, low latency, bandwidth and performance in multiple directions, not just East-West / North-South with the help of SynchroKnot Multi-Dimensional topology.

■ SynchroKnot Multi-Dimensional topology is a dynamic mix and integration of proven network topologies which are used as a primary backbone in High Performance Computing and Supercomputing. These include Ring, 2-D, 3-D and many other custom topologies optimized for cost, performance and simplified cabling.

■ Single-length cable for the entire cluster. No long haul cables. No expensive power-consuming optical cables.

■ Very low CPU usage.

Apart from all these features, there are multitude of extra security features to choose from on top of the Satellite Tree Protocol.

Flood Ping Fun with 24 Switches in a Ring Topology!

This demonstration video shows a total of 24 Ethernet switches in one large loop [ Ring Topology ] with Satellite Tree Protocol enabled and multiple switches being brought down and up every 10 seconds while Flood Pings are underway from multiple directions!

The SynchroKnot Satellite Tree Protocol an enhancement to the IEEE standard [ 802.1D (1998|2004), 802.1W ] while keeping the core semantics in place, and is a part of SynchroKnot Spatial Defined Networking.

Satellite Tree Protocol is the core networking component of the SynchroKnot Cloud Computing and Data Center Decentralization software which transforms any server, workstation, desktop or embedded device into a decentralized cloud or data center [data decenter].

The object is to ascertain the automatic and fast network resilience [root bridge failure, failover and failback], fault tolerance and intelligent path selection capabilities amidst very low hardware resources.

This demonstration setup has been purposefully done with an illogical setting so as to test how it can perform in extreme circumstances.

Mininet is used for actual network emulation.

You may also notice results of prior flood ping tests in the demonstration video before the current one gets underway.

We would like to assume that the outcome result with 0% [zero percent] packet loss with 24 switches is a bit much for our logical mind to digest and would love to blame the ping utility with a faulty flood ping option 🙂 ….. of course upon deeper contemplation you may develop an insight that differs.

■ In actual use case scenarios, with our unique cabling technique in a 5 X 5 2-D Torus topology, one may generally not have more than one or two hops! 24 nodes are used for purposes of extreme testing in difficult case scenarios.

■ Simple machine with 2 cores [4 threads] Intel Core i7-6500U Processor with 8 GB RAM. Alongside, a few running virtual machines not a part of this demo were used in the background to consume CPU and memory resources, leaving fewer CPU cycles and memory for Satellite Tree Protocol and the 24 nodes with Mininet. [This demonstration video was also recorded on the same machine and thus used additional CPU cycles and memory.]

■ Side Note : Spanning Tree Protocol and Rapid Spanning Tree Protocol generally respond to failures by recovering in about 40 to 300 seconds or more depending upon the timers and topology [ RSTP may recover faster in some scenarios ]. This is with the regular vendor / standards suggested timers found in most switches in standard setups today. One can increase the network diameter [ i.e number of switches between two endpoints ] to a maximum of about 18. This however will substantially increase the recovery time, alongside most likely put the timers of switches out of sync. Your mileage may vary. Please do your own research.

■ Caution : If you try a similar setup with standard physical Ethernet switches [Cisco, Juniper etc] then you are solely responsible if you brick your appliance(es). We cannot help you recover them.

In brief, the SynchroKnot software transforms any server, workstation, desktop or embedded device into a decentralized cloud or data center [data decenter]. You can use any commodity X86_64 Desktop/Workstation/Server/Embedded device and connect them to eachother. There is no need to purchase physical or virtual switches and routers or any of their licenses [Eg. Cisco, Juniper etc].
