MVO – Creating a More Intelligent Connection

MVO uses the patented TMP protocol for transport across the WAN. Utilizing TMP enables

MVO to provide strong optimization for industries that rely on delivering exact original content

without caching or compression.

TMP Protocol • Creates a more intelligent connection

• Enhanced connection mitigates congestion, latency and

fragmentation

• Variably aggressive ramp rates, real time bandwidth limits

discovered very quickly

• TMP not "loss based“, looks at real-time patterns

• UDP based application level protocol

• Increased bandwidth supported and significantly less latency per

request

• Increase the number of simultaneous connections (mobile)

• OTS Hardware

• Leverage cutting edge hardware – industry moving towards

specialty hardware as plugins

– NICs (1GbE, 10GbE)

– CPUs (offload L3 cached optimizations, QPI optimizations)

• Leverage open source software where possible (Linux), tool

chains

• Leverage OEM library extensions to OS to support new hardware

• leverages and builds upon Linux in-kernel services

• It was a conscious decision by the team to not rewrite network

stacks and kernel services (like scheduling) that provide the

fundamental corner stone’s and underpinnings

• not to re-write TCP or UDP for interoperability reasons

• Leverage in-kernel Linux operating system’s services and

technology to drive network protocol interconnects at wire speed.

• leverage an industry standard operating system and OTS

hardware to provide a high performance low-latency software

subsystem with industry standard interoperability. SELinux and

other LSM’s, iptables rules, and all the tool chains, user tools and

commands, are leveraged

• The WAN modules are responsible for providing a tunnel between a

Remote and Hub appliance with the following characteristics:

• Guaranteed delivery of packets

• Adjust packets to the configured MTU

• Support multiple streams within a TMP tunnel (connection)

• Packets delivered in order

• Multiple Remotes to a single Hub

• Single Remote to a single Hub

• Protocol optimization - Congestion algorithms on a per-tunnel connection

– Congestion window management

– Priority packet delivery

• TCP Proxy Module responsibilities:

• Locally Terminate TCP client connections (Remote)

• Receive input from the client and provide this zero copy data to the MVO

Application Module (TMP on remote)

• Receive Input from the MVO Application Module and send to the

originating client (Remote)

• Send CPF commands on a per StreamId (unique per connection ID) via

the MVO Application module from the Remote to the Hub to open a TCP

connection to the original Destination on the Hub

• Receive output from the MVO Application Module and transmit to the

original destination module’s server (HUB)

• Receive input from the original destination server and provide the zero

copy data to the MVO Application Module (Hub)
