Adaptive Routing and its advantages

Adaptive Routing and its advantages

Adaptive Routing:
  •          Adaptive Routing used by almost all packet switching networks
  •           Routing decisions change as conditions on the network change
    •         Failure
    •         Congestion
  •        Requires info about network
  •        Decisions more complex
  •        Trade off between quality of network info and overhead
  •         Reacting too quickly can cause oscillation
  •        Too slowly to be relevant 
Advantages of Adaptive Routing:

1) Improved performance
2) Aid congestion control 
3) Complex system
4)May not realize theoretical benefits

    Chainsaw sharpener are a vital element of increasing the entire life of a chainsaw. You can elect for stihl two in 1 chainsaw sharpener because it is best. Timberline chainsaw sharpener is an excellent alternate. You can watch for a Good Deal More choices from this elaborated manual:Chainsaw Sharpeners

Client Server Computing with Adaptation

Image
Client Server Computing with Adaptation • Two adapters (adaptation software) at a mobile device • An adapter for standard data format for synchronization at the mobile-device • Another adapter for the backend database copy, which is in a different data format for the API at the mobile-device Adaptation: Software to get data in one format or data governed by one protocol and convert it to another format or to data governed by another protocol ·          Used for interchange between standard data formats and data formats for the API ·          IBM WebSphere Everyplace Access (WEA) provides adapters for synchronization objects (for example, XML format synchronization objects) and the objects of API databases (for example, for the PIM APIs)

Data Dissemination Broadcast-disk Models

Image
Data Dissemination Broadcast-disk Models: ·          Presumed that all the n records to be broadcast are stored on a circular disk from 0° to 360° ·          A hypothetical disk revolves and the angle changes from 0°to 360° ·          The entire N bits in n records get pushed through a hypothetical reading-head over the disk. ·          The head continuously reads each bit of a record just beneath it and broadcasts it instantaneously on the wireless network ·          During next revolution each bit in the records positioned from 0° to 360° broadcast once again in the same sequence as in earlier revolution Number of adaptations and algorithms for broadcast: 1. Circular Multi-disk Model 2. Flat Disk Model 3. Multi-disk Model with repetition rate proportional to priority 4. Skewed disk model Circular multi-disk model • Each block of records pushed with a repetition rate proportional to its hierarchical level Each rotating disk cycle:
