Multipath Routing

1
Multipath Routing

• Present scenario
• Single path routing in most of the servers
• Drawbacks
• If some bottlenecks
• restricted bandwidth
• slow network resource

2
Alternative

• Connect the two ends through multiple independent
  routes
• Advantages
• Increased bandwidth
• Faster network services

3
To achieve this, following functions need to be
modified which are normally called for a single
path routing

• Server calls
• socket( )
• Bind( )
• Listen( )
• Accept( )
• Client calls
• Socket( )
• Connect( )

4
General Idea

• To use a number of proxy servers over the
  internet as intermediate connection points
  through which independent routes to the
  destination can be established

5
New Scenario

• Multipath senders
• Incoming request of the client has to chopped to
  be sent to different proxy servers
• Multipath receivers
• Incoming responses have to be assembled before
  being sent to the client
• Connection Relay Server
• Proxy servers on the Internet

6
Design
Sender
Receiver
Proxy Server
Multi path Sender
Multi path Receiver
Proxy Server
7
Conclusions

• Design a new library of function calls for
  multipath server, multipath sender and connection
  relay servers.
• The library should allow the sender to express
  the list of connection relay server proxy servers
  used.
