Latency is not a new problem in networking. Not as difficult as time travel, but it’s difficult enough so that for 30+ years IT professionals have tried to skirt the issue by adding more bandwidth between locations or by rolling out faster routers and switches. Fast forward to today, most networks enjoy five nines (99.999%) of uptime.

As networks become distributed and virtualized, the points at which they can be made vulnerable, or their threat surface , expands dramatically. This is compounded by recent trends of remote work, where network operators need to wrestle with the fact that employees often access the network via work sites with far less governance.

Supporting GenAI at scale has meant rethinking how our software, hardware, and network infrastructure come together. Solving this problem requires a robust and high-speed network infrastructure as well as efficient data transfer protocols and algorithms. requires revisiting trade-offs made for other types of workloads.

I also pointed out that because of necessary factors like redundancy, the pursuit of reliability will inevitably mean making compromises that affect a network’s cost or performance.

There is a lot of confusion regarding the two primary data sets in network management: SNMP and flow. SNMP is used to collect metadata and metrics about a network device. This critical technology is a basic building block of modeling, measuring, and understanding the network. What is SNMP? What is Flow? When is SNMP Used?

However, in order to operate a reliable stretch cluster, datacenters must be relatively close to each other and have a very stable, low latency, and high-bandwidth connection among the DCs. In a multi-datacenter cluster, network ingress and egress can be very costly—certainly more costly than network traffic within a datacenter.
