Accelerate chatty applications that use well known protocols such as CIFS and MAPI

Save bandwidth on LAN links

With a single TCP session, effectively use bandwidth on high-speed WAN links

Reduce UDP traffic on the WAN by engaging Riverbed Professional Services

Remove the traffic load from MAPI servers

Override the value with a default of 0

Override the value with the value of AF11

Reflect the value received by the original packet

Reflect the value returned by the symmetric TCP flow

Drop the new data

Create a tunnel to optimize the data

Scalable Data Referencing creates and sends new reference pointers to the peer Steelhead appliance

Compress the data using Lempel-Ziv and sends it to the peer Steelhead appliance

Sends only the references for the data to the counterpart Steelhead appliance

Serial in-path

Logical in-path

Server-side out-of-path

Parallel in-path

All of the above

Straight-through cable

Crossover cable

Router

Firewall

None of the above

Cold, the data now travels in another direction so the Steelhead appliance needs to relearn the data

Cold, the file has been changed to the file needs to be stored again

Warm, all the data has been seen by the Steelhead appliances before

Warm, the transaction prediction module of the Steelhead appliance can detect the application and accelerate the transfer

Partially warm, the Steelhead appliances only need to learn the new data

SteelHead Mobile optimization

HSRP or VRRP gateways

Licensing is based on the number of SaaS applications to optimize.

Licensing is based on the number of SteelHead appliances to be enabled.

Licensing is based on the number of users requiring SaaS optimization.

Licensing of SaaS optimization is included in the support contract.

Yes, because we see the Cloud icon in the notes Section.

No. You must look in the connection details.

No. Although 132.245.229.178 is a Microsoft address the optimization could be happening through a Cloud SH and not SH SaaS.
