    the ISP will has to pass through many intermediate states depending of its transformation strategy netTransformer has been used to generate the states and to make a formal diff between them The transformation from a state to state happens by executing a set of steps that in the end get parameters from the models and execute a set of templates through a management protocol on one or more network devices Finally the software supports a network rediscovery and a diff between the newly reached network state and the previously discovered one prior the execution of the step That way the network engineer can ensure that the desired state has been reached and the envisioned effect of the transformation step has been achieved From network mapping perspective netTransformer generates 3 distinct data models hierarchical xml device centric data model of the network device containing information about the device its key metadata its ports interfaces and protocol neighbors graph based device centric data model in graphml file format produced by xslt transformation of the device data xml graph based network centric data model in graphml this is a network wide model produced by merging all device centric graphmls The software is generating topology views and network topology diff views from the network centric data model Thus a lot of people use it simply for network mapping One of the important other concepts of it is that each network has to be treated as a separate project Since there are many kinds of networks through the years appeared various kinds of project types The current one are SNMP Network Discovery able to discovering and visualize IP networks based on various metods like OSPF BGP CDP LLDP Direct links next hops Blue is Metro Ethernet red is MPLS core layer Same topology this time

  • DDOS Protection for Enterprise applications and web infrastructures | iTransformers.net
    they do First will occupy your DNS and will redirect your publically accessed points towards their infrastructure Then they will allow funcitonality that will snapshot your site so if you site has dynamic contect simply forget about them finally they will tunnel the traffic from their infrastructure to yours So but how will that help you In parallel with that they will apply RTBH They have connections with some ISPs and major content hosting providers and will try to hide them and you from the eyes of the attacker This works sometimes if you are lucky and your stuff has been hosted in an ISP with which they have good connections but in many cases and in many contries their service simply won t work well Thus instead of using such complex solutions we offer you a way to help yourself If you an ISP and would like to use our ddos servlet filter you can easily expose it as an API and grant access to your customers to it So once they are under an attack they would pull the triggers notify your API and you will block the attakcer traffic for them How the traffic will be blocked since we don t apply security rules or imply complex security equipment being used Well we will simply a bit the situation and will blackhole directly the traffic on IP forwarding level at the endge of your network Since the edge is typically distributed this method even if it does not give 100 guarantiees offers the most scalable way of dealing with DDOS It has been described in RFC 5635 and has been used by Google amazon and many many other ISPs If you a final customer of an ISP your choice is to look for and ISPs or hosting
