Telecom backbone networks have transitioned to cloud-interconnected infrastructures where IPsec is essential for secure communication, especially across mobile backhaul and interconnects. With the growth of virtualized architectures, operators now utilize IPsec to ensure encryption, authentication, and integrity, adapting to diverse environments and evolving security needs in modern telecom networks.

IPSec vs MASQUE
For decades, private traffic hid inside a special protocol. IPsec, OpenVPN, and WireGuard still do that: they punch an encrypted L2/L3 tunnel across the public path, then stuff TCP, UDP, SCTP, or RTP inside it. Middleboxes learned the silhouette. ESP is protocol 50. IKE is UDP/500. If those ports are blocked, the VPN is gone. … Continue reading IPSec vs MASQUE
SCTP (Stream Control Transmission Protocol)
SCTP (Stream Control Transmission Protocol) is a robust, message-oriented transport layer protocol designed for mission-critical applications that demand reliability and fault tolerance. Originally developed for telephony signaling—specifically for SS7 (Signaling System No. 7) over IP—SCTP has evolved into an essential protocol for modern telecommunications, WebRTC data channels, and high-availability networks. Its unique capabilities make it … Continue reading SCTP (Stream Control Transmission Protocol)
