Our customer are considering introducing DCRUM. So they ask us the following questions of WAN Optimization.
Would you tell us the answer?
Question1: How does the DCRUM classify as WAN optimization packets or other? Is the WAN optimization packets classified by Web Cache Communications Protocol (WCCP)?
(I understand that WAN optimization corresponds Riverbed and Cisco products.)
Question2:If DCRUM use WCCP to classify the WAN packets, does WCCP version affect the classification of the pakets? (If WCCP protocol changes the specification, DCRUM can not classify the packets?)
Question3: I think that the WOC side OS of Riverbed and Cisco will rarely change OS version. If Question 1 and 2 are correct, the OS version does not affect the WAN optimization culcuraton of DCRUM. Is this correct?
Answer by Kris Z. ·
DC RUM does not use protocol analysis to classify WAN-optimized versus LAN traffic. Protocol analysis is used to match LAN and WAN traffic in order to measure efficiency of the WOC and extrapolate end user experience on the far end side of the WAN.
Classification of the WAN versus LAN side of the WOC can be done on the basis of pointing out the AMD sniffing interface that receives LAN or WAN traffic copy, and/or VLAN tag that carries WAN or LAN traffic, and/or WCCP ID that carries LAN or WAN traffic. In fact, classification is three-fold: WAN, LAN that is subject to optimization and all other LAN (data center LAN) that is not a subject to optimization. When configured, AMD matches WAN and LAN traffic using criteria as mentioned and uses protocol analysis to perform measurements.

Thank you for your explanation. Your explanation was very helpful for us.I understood this content.
Now we are making the DCRUM proposal to many our customers, so I'd like to learn a lot from you and all member.
