c# - Server Push vs Client Pull for Agent-Server Topology -


I need to create a system with two components:

  • A single server Which processes the data and stores it periodically sends updates to agents

  • Multiple agents that are installed on remote endpoint collect data (often But not always) long-running operations, and this data needs to go to the server

I am using the Net, and ideally I want to use the communication method in accordance with standards (i.e. one that can work with Geo, because we can also use Java agents in the future). Is there any alternative to web services?

  • What are my options?

    The way I see, I have 3 options using web services, and have made the following comments:

    • Client pull
      • <
      • Push the server
        • <
        • Hybrid
          • Port on Open Agent, because it both a client and server
          • no polling is; The server removes the update when it is required,

          'hybrids' (where the agent is both clients and The server seems obvious - but this app will usually be installed in enterprise and government environments, and I worry that there may be a problem opening a port on the agent. / P>

          Does any other professional and opposition I do not remember?

Our friends swear by bridge based system:

A major reason for liking client-pull at server-push is that clients may be down, and clients should generally implement all operations pushing by all servers. If these criteria are not important in your case Maybe, their conclusions will not be your conclusions, but I guess Confirms that it is worth reading the "push versus pull" section of your paper, to define yourself.

Eclipse CDT variable colors in editor -

I hope this is a good question to ask here. This programming is related, so I thought it would be better than the superuser, so I am using the CDT C ++ Eclipse plugin. I know how the editor changes colors for some things But is there a way to do that all the variables are different colors? For example in KDEValue, it sets the local variables and square variables in different colors and bold square squares. Can I copy it to CDT? Eclips provides some level of color customization for text editor syntax You can see it on the following: There are many elements, including the Window> Preferences> C / C ++> Editor> Syntax color code that can be changed, assembly, Comments, Preprocessor and Doxian Under the code, it is possible to change the color of some variable types, such as global variables, local variable announcements, local variable references, and parameter variables. But I do not think the code is capable of changing the color of each variable declared....
