The Mirage NFS Router

Mirage is a network router that performed various virtualization operations on the NFS operations that pass through it. Virtualizations include:

• Aggregation: Combine two or more NFS servers into a single large server
• Replication: Combine two or more NFS servers into a single more reliable server
• Fortification: Make an NFS server more secure (prevent Denial Of Server attacks)
• Transformation: Convert the NFS protocol into something different (like NFS --> HTTP)

Goals of Mirage include:

• Transparency: Mirage should run on unmodified clients and servers
• High-Performance: Packet rewriting techniques are used to rewrite and forward packets on the fly

Two Mirage prototypes are currently in production:

• User-mode Mirage: Runs on commodity Linux machines, used as a "proof-of-concept"
• IXP2400 Mirage: Runs on specialized IXP2400 network routing hardware. The primary goal of implementing Mirage on the IXP is to yield greater performance.
