Modern switches and routers often use dynamic RAM (DRAM) in order to provide large buffer storage space. However, the effective bandwidth of DRAM is frequently a limiting factor in the design of ...

Spiraling network line rates, presently hitting up to 10 Gbit/second, are approaching the performance limits of the packet buffers in today's datacom line cards. For its part, buffer-memory ...

Cisco routers use buffers as blocks of memory to handle data during the network routing process. As data flows through a network, different rates of transmission occur between routers and network ...

This vendor-written tech primer has been edited by Network World to eliminate product promotion, but readers should note it will likely favor the submitter’s approach. Server virtualization is ...

Bufferbloats—an amusing word for a less-than-delightful issue (we reported on these last year). A bufferbloat is the proliferation of more and more buffering of IP packets in routers, switches, modems ...

In the AV industry, we often think of the delivery of audio or video in terms of three major components: the source, the network, and the receiver or playout device. Many researchers in the IT ...

LOS ANGELES—This is the second installment of a contribution from Jim DeFilippis on SDI versus IP. For Part 1, see “Which Switch is Which?” The second tale-of-the-tape issue is delay or latency. There ...

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 ...

This comprehensive guide covers everything you need to know about deep packet inspection, the practice of sniffing web connections to reveal sensitive user data and fend off cyberattacks. Every parcel ...

What would happen if we couldn’t agree on the same time? Team meetings would never start on time. You might go catch a movie only to find it was over an hour earlier. Nothing would get done and the ...
