Uncontrolled copy when printedUNCLASSIFIEDACP 200(B) Vol 2Binary files, and non-repeating data, do not fare as well as Web and text files, which are morecompressible.QOS SOLUTIONS243. Today there are a plethora of vendors who offer end-to-end solution packages. Thesehardware devices called WAN accelerators or optimizers, compress and cache data, modifyTCP parameters and enforce QoS (quality of service) using prioritization and rate shaping.244. While some vendors claim their devices increase network performance tenfold,independent tests have typically demonstrated a fourfold improvement in throughputperformance. Protocol prioritization and rate limiting QoS mechanism vice DifferentiatedServices (DiffServ) or Integrated Services (IntServ) technologies are typically employed.245. Such solutions are attractive due to the fact that they are relatively simple to deployand maintain. With the devices strategically positioned they can monitor and visualize thenetwork. Once the traffic flow is understood then QoS mechanisms can be introduced tocontrol optimize the flow, and if the infrastructure provides pair-wise configuration, thencompression can also be applied.INTEROPERABILITY246. While most / all vendors implement industry standards, there is no interoperabilitybetween vendor solutions.PASS THROUGH FAILOVER247. It is desirable that any solution has pass through failover. That is if any hardwaredevice is unplugged, traffic will nonetheless pass through the device as if it were part of thewire.NETWORK TOPOLOGY248. The hardware device should be able to be deployed in a hub-and-spoke or meshtopology. Those devices that require you to create links manually, however, are difficult toconfigure in a mesh environment.FUTURE WORK249. AUSCANNZUKUS nations are actively exploring QoS packages which should leadto a better understanding of QoS and vendors solutions. The information gleaned will be usedto further develop this chapter in subsequent changes.250. QoS approaches that can be implemented at the router (vice through WANaccelerators / optimizers) need also to be agreed.2-11 OriginalUNCLASSIFIED
Uncontrolled copy when printedUNCLASSIFIEDACP 200(B) Vol 2MAPPING IER TO QOS251. An outstanding issue that remains is how to map the war fighters‘ InformationExchange Requirements (IERs) into QoS outcomes while maintaining transparency toCommand. There is significant work being done in this field which will be reflected in thenext change to this document.IPV6252. The development of IPv6 will enhance our ability to perform QoS and manipulatepacket flows. Until 2003, all routers were packet routers that only examined the packet andkept no flow history. The duration, rate or byte count of the flow could not be determined.Flow State Aware (FSA) routing such as Multi Protocol Label Switching (MPLS) candetermine the duration, rate or byte count of the flow. It can identify flow types and controlthe rate and delay per flow.CONCLUSION253. Link throughput, vice bandwidth is the most important consideration when addressingIP connection speeds. QoS mechanisms can significantly enhance throughput and improvetransmissions, without requiring extra bandwidth.254. In order to effectively and efficiently implement QoS, it is important to understandwhat is occurring in the network (i.e. visibility). Once this is understood, QoS control andcompression can be implemented. The overall goal, however, should not be to squeezeimprovement out of <strong>MTWAN</strong>s, if it adds undue complexity to training and operations.2-12 OriginalUNCLASSIFIED
