Great Article on Distance Vector Routing Algorithms
I submitted an RFI (Request for Information) to Florida Dept. of Transporation (FDOT) and it was based on TRILL, they wanted something like SPB (Shortest Path Bridging), but what I found to help address some of their traffic issues would be to implement a Distance Vector Routing Algorithm into the mix which redistributing the routes using R-bridges and IS-IS (Intermediate System Intermedia System).
dx(y) = minv{ c(x,v) + dv(y)}     for each node y in N

"Distance vector routing is an asynchronous algorithm in which node x sends the copy of its distance vector to all its neighbors. When node x receives the new distance vector from one of its neighboring vector, v, it saves the distance vector of v and uses the Bellman-Ford equation to update its own distance vector. The equation is given below" - Distance Vector Routing Algorithm or DRA for short

TRILL (Transparent Interconnection of Lots of Links), it uses R-Bridges; R=Route Bridges are used to communicate with each other by creating a grid. This grid could be used to connect the internet in a way where each link shares cost information with its surrounding neighbor; however, if there are links that go down, it uses the DRA to route traffic through another route-bridge. In this example, we can use R1, R2, R3 (indicative on the chart) to help route traffic across the globe without traffic being disrupted (self-healng and learning by creating a math matrix based upon specific factors). Dr. Injong Rhee (NC State Univ. professor, now with Samsung) came up wtih BIC-TCP and CUBIC to help address some of the routing problems with tcp windows adjustment size on the fly but that is for another conversation (CUBIC is used in VMware as part of its routing algorithm, but it has to be selected).

TRILL Link Connections

 

So even if we removed a route, connection or link, the system would be able to learn and route traffic by using another path, again the system has the ability to learn based on priority, path, speed, and congestion (the X, Y, Z are criteria and the numbers represent specific patterns and priorities associated with the network (TRILL - Link State Routing Algorithm and IS-IS can both work with IPv6 to address convergence issues because IPv6 addresses HOP/Distance count, MITM attacks,  Security (IPSec VPN) and it works with globlal routing protocols like MPLS and BGPv4 but if properly configured, TRILL could feed into IS-IS and IS-IS could feed into BGPv4 or MPLS. The links are represented by one count so the number of hops can be signficantly reduced thus improving performance and reduce routing cost/redundancy.



From a prior conversation, this would be a geat use case where ML can quantify better metrics and calculations identify improvements in the algorithms and routing security issues.

Possible ideas to ponder over.

How Machine Learning, AI & Deep Learning Improve Cybersecurity
Machine intelligence is influencing all aspects of cybersecurity. Organizations are implementing AI-based security to analyze event data using ML models that identify attack patterns and increase automation. Before security teams can take advantage of AI and ML tools, they need to know what is possible.
