Role of coonector

communication coordinators

conversion facilitators

Communication

A)Supports:Differ commun machine

E.g. procedure call, RPC,shared data

access,message passing Constraints on commun

structur/direction E.g. pipes

B)Constraint on quality of services

E.g. PrrsistenceC) Separates communication

from computation.

D) Many influence non functional system

charactersticsE.g. Performance , scaliblity ,

security

Converters E.g. Adapter,Wrappers

Enable interaction of independently

developed, mismatches componets.

Mismatches based on interaction

type,number,ferqunacy order.

Facilitators E. g. Load balancing, provide synchronization mechanism for critical section & motion

Enable interaction

of componets intended to interoperate

Mediate & streamline interaction

Govern access to

shared information

Ensure proper

performance profiles.
