The packet is routed on the network, and the first router decrements the TTL by 1, leaving it at 0. This causes the router to drop the packet and send "ICMP Time Exceeded" back to the source. The client increases the TTL 1, allowing the packet to be routed through one additional hop...
For example, S/MIME protocol works at Application layer, SSL protocol is developed to work at transport layer, and IPsec protocol works at Network layer.In this chapter, we will discuss different processes for achieving security for e-mail communication and associated security protocols. The method...
While NSGs, UDRs, and forced tunneling provide you a level of security at the network and transport layers of the OSI model, you might also want to enable security at the application layer.For example, your security requirements might include:...

The NSH solution can solve some problems of PBR by separating the service layer from the network layer. However, it still has disadvantages. For example, it requires each SFF to maintain the forwarding status of each SFC, increasing control plane complexity. In addition, transparent NSH transport...
For east-west type load balancing, Cilium performs efficient service-to-backend translation right in the Linux kernel's socket layer (e.g. at TCP connect time) such that per-packet NAT operations overhead can be avoided in lower layers. ...
