Modern Telecom Network Tracing

Packet capturing is a fundamental component of any network monitoring system. It can provide sophisticated intrusion detection for an enterprise VPN, or help mitigate huge scale DDoS attacks on the web. In a telecom network, it provides, among many other things, the necessary visibility into the traffic in order to detect and root cause any possible scenario that would lead to a disruption in service to our users. It’s a well established space, with tools ranging from dedicated hardware to in-kernel support to even bypassing the kernel itself. Complete solutions that provide full visibility into a telecom network are, unfortunately,…

Telecom (as We Knew It) Is Dead

From time to time, the 3GPP standardization body surprises everyone with bold moves in selecting strange technologies. It did so with RCS, IMS, and SIP. When they first announced the 5G core evolution as a cloud-native architecture with HTTP as the main communication protocol, it raised some eyebrows. With Release-15, everything that telecom stood for is gone. No more engineered protocols for efficiency during times of high traffic volume. No more interoperability testing with different vendors and new protocols. The telecom king is dead, and there will be no more, “Long live the King!” because today, a kid using node.js…

OXIO’s Customer-Tailored API Opens Opportunities for MVNOs to Evolve

Carriers are often protective of opening up core network components. As a result, MVNO’s have essentially been given an inflexible black box as their sole integration endpoint. Locked out and unable to obtain the business intelligence needed to establish themselves in a competitive market, MVNOs often resort to cannibalizing their own margins to lower consumer costs. As this plays out across other networks, it creates a race to the bottom. With MVNOs all fighting to lower prices, the value of carrier-direct plans declines along with the overall customer experience. The cycle begins with that inflexible black box. While carriers may…
