Data Transfer Tasks: Time Batching in Network

Data Transfer

Switching networks? Take care of a tradeoff between encryption and security

The encryption process serves as a chokepoint between protected and usable data. Regardless of how you set up your encryption technology, you want to make sure that it has enough resources and enough resource pools.

From an application architecture perspective, application-level encryption involves many diverse and interdependent processes that can be aggregated into a few groups:

  1. Direct impact: You will be penalized for reading and writing.
  2. Maintenance: Operations teams are affected by maintenance complexity and new procedures/processes/limitations.
  3. Housekeeping: These processes affect system design, developer experience, and SLOs through background and on-demand key lifecycle processes.

Generally, the more fine-grained the integration with the application, the easier it will be to manage the three types of issues. However, as with any tightly coupled system, changes will become more difficult.

You can balance trade-offs in your encryption subsystem when you understand performance requirements and SLO impact:

  • Read/write decoupling. The decoupling of the read and write keys and the reads and writes of cryptosystems (and network security products) is a feature of some cryptosystems. The downside is that it has security implications and performance penalties (since additional math is needed). Still, it’s a good way to implement “write-once, read-often” systems.
  • Consistency. Because encryption adds a few more steps between wanting to write the data and doing so, it is essential to understand the trajectory and safe failure modes.
  • Multi-key setups. If the system is expected to change arbitrary keys frequently, use multiple key-encryption keys (KEK) with access settings of “valid for reading” or “valid for writing.” Key encryption keys protect data encryption keys (DEK). With this multi-layered scheme, it is possible to roll keys without interfering with service.
  • Batching. With batch encryption (encrypting several records at once instead of individual records) multiple objects can be encrypted/decrypted together to reduce initiation/network request/context switch/data transfer costs.
  • Typical performance improvements: A lot of best practices you would use if you wanted to improve the performance of a high-load system apply here—provisioning enough processor cores, setting up efficient multi-threading, and providing enough RAM are all first-level problems that contribute to encryption’s performance hit.

You’ll Be Shocked At The Productivity And Happiness Gains You, Will, Experience When You Try [Time Batching]

Switching tasks involves a mental process called goal shifting, as well as rule activation. By moving the focus to a new task and away from an old one, goal shifting is achieved. The rule activation process involves getting rid of mental rules associated with the old task and activating mental rules associated with the new task. Even though these executive control processes are rapid and come quickly, after a day of work they can produce a great deal of exhaustion. According to the researchers, mental switching could reduce an individual’s potential efficiency by 20-40 percent.

To discuss time batching, let’s look at the technique. As a result, we need to group mentally and intellectually similar tasks and then set aside a certain amount of time (even if it is only 20 minutes) to concentrate exclusively on these tasks.

Suppose I track my time for a couple of days and I discover that the tasks I accomplish all fall into the following categories:

  • Thinking deeply (concerning new research studies, writing books, and articles, etc.).
  • Developing new skills (education, learning a new statistics application, etc.)
  • Interacting with clients and giving presentations
  • Working on administrative tasks (returning emails, managing budgets, talking to accountants, etc.)
  • Interactions with my staff (one-on-one conversations, staff meetings, etc.)
  • Anything to do with statistics, analysis, and data

There is a similar kind of thinking involved in all four buckets. Working at my deep thinking bucket, I’m able to exercise creativity, brainstorm, innovate, and be curious about what I’m doing. In contrast, I’m using my math skills to analyze every single decimal point in my statistics & data bucket.

Scheduling my work in such a way that I’m hoping between different buckets of work is something I want to avoid. When I conduct an internal budget review or hold a staff meeting, the thinking rules I apply are completely different than when I write an article. I will need to expend more mental energy to try to get in the right frame of mind as I jump from one activity to another. By switching between buckets more frequently, the more mistakes I shall make.

This can even be taken to the next level. Tracking my time for a week would reveal that I’m far happier and more productive doing my deep thinking very early in the morning or at the end of the day (or whenever). If I know where I do my deep thinking best, I will schedule some blocks of time throughout the week when my calendar shows I am busy and I can concentrate without interruption.

While I would prefer to have those blocks of time last for at least an hour or two, even 30 minutes of thought can yield significant outcomes. These suggestions apply to all of the buckets as well. For example, I am not able to do deep thinking right after lunch. However, I have a great deal of success conversing with clients or my staff during that time. Thus, whenever I have a choice of meeting times, I will schedule client and internal meetings in the late afternoon. Even if I have a little more time after those meetings, I will keep doing projects in the same bucket so I don’t have to switch my focus.

Switch: What it is and why it is important

Switches link the two nodes to ensure unified data transfer through devices that are not physically connected. Information can be distributed quickly and efficiently to the appropriate node so that the end-user receives the right information.

Switchmen perform maintenance on the hardware used to control multiple and interconnected devices such as telephone switches, operating points in communication systems.
