Snoop TCP: Advantages

• Preserves end-to-end TCP semantics
  
  
• Requires no changes in TCP for fixed hosts
  
  
• No changes in TCP are possible for the mobile hosts, but reverse direction traffic can benefit from changes at mobile host
  
  
• There is no need for handoff
  
  
• Automatic fallback to standard TCP
  
  
  • No need to ensure that all foreign networks provide a Snoop agent
