Today Juniper Networks announced several innovations that will simplify service delivery in the metro for operators across cable, residential fiber, direct public cloud connectivity and various mobile backhaul services. Juniper’s Metro Fabric provides operators with an adaptive software layer and agile infrastructure that, when combined, create a holistic service-centric fabric that simplifies operations, mitigates infrastructure churn and continuously optimizes network economics.
In the late February 2018 enormously high-volume DDoS attack was observed. It was UDP based memcached service reflection-and-amplification attack, reported as 1.4Tbpos strength.
The 1.4Tbps it is more than entire network capacity of many SP. The big SP of the world has network with higher capacity, but even for them – why to waste 10-20-30% of their resources to carry malicious traffic? So – DROP IT! And do this as early as possible.
Tunneling was invented to connect networks separated by other independent networks. One classic example is the VPN use case where remote access users connect to a variety of network resources (corporate home gateways or an internet service provider) through public data networks. Tunneling is simply encapsulating a packet in another packet. In this, the devices at the network entry and exit points play a pivotal role of doing the encapsulation and de-capsulation respectively, and hence are responsible for building/maintaining the necessary state that facilitates this tunneling, while the rest of the devices in the network seamlessly transport based on the outer headers.
