Most network people understand the terrible effect delay can have on TCP sessions. TCP must pause data transfers while waiting for ACKs. The more network delay there is, the longer this pause will be.

Transmission Control is an essential aspect of network activity and governs the behavior of many services we take for granted. When sending your emails or just browsing the web you are relying on TCP ...

The data transfer in a TCP/IP network is usually block-based. From a programmer’s point of view, sending data means issuing a series of “send data block” requests. On a system level, sending an ...

Security and networking platforms for large enterprises and data centers are rapidly evolving in sophistication and performance. In the security space, simple packet-filtering firewalls are evolving ...

Bandwidth represents the theoretical maximum capacity, while the data rate (or throughput) is the actual, real-world speed ...

Stephen Shankland worked at CNET from 1998 to 2024 and wrote about processors, digital photography, AI, quantum computing, computer science, materials science, supercomputers, drones, browsers, 3D ...

Packet queues are a core component of any network stack or device. They allow for asynchronous modules to communicate, increase performance and have the side effect of impacting latency. This article ...

In the last newsletter, we continued a discussion of discarding voice vs. data packets. This time we’ll continue that discussion with a proposal for how data transmission could be greatly enhanced by ...

A clever antimalware gateway can achieve zero latency by using a span/tap port to inspect Internet traffic for malware and malware references (in contrast to inline inspection). When it recognizes ...
