This can be coupled with a configuration that applies a specific DSCP marking to the packets within the flow.
WAVE appliance models and do not have externally accessible hard disk drives, and with a single hard disk drive, do not support RAID. The Cisco WAVE model WAVE is a single-processor desktop model that is designed for deployment in small- and medium-sized branch office locations or small data center locations. Licenses are not enforced in WAAS; however, licenses can only be applied to platforms that support the particular license in question.
Sample Chapter is provided courtesy of Cisco Press. This module is not capable of running the advanced services enabled by the Enterprise license discussed later in the chapterincluding application layer acceleration or disk encryption. The network interception and bypass manager is used by the Cisco WAAS device to establish relationships with intercepting devices where necessary and ensure low-latency bypass of traffic that the WAAS device is not intended to handle.
The Cisco WAAS product family consists of a series of appliances and router-integrated network modules that are based on an Intel x86 hardware architecture.

It also looks at the licensing options for Cisco WAAS, positioning for each of the hardware platforms, and architecutre and scalability metrics for each of the platforms. These include disk encryption, Central Management Subsystem CMSinterface manager, reporting facilities, network interception and bypass, application traffic policy ATP engine, and kernel-integrated virtualization services, as shown in Figure With two drives, the system is configured automatically for software RAID Architecyure and scalability metrics for each are examined later in this chapter, along with best practices around accurately sizing a Cisco WAAS deployment.
Sizing of a Cisco WAAS solution requires consideration of a number of factors, including network conditions WAN bandwidth and LAN throughputnumber of users and concurrent optimized TCP connections, disk capacity and compression history, memory, concurrently connected peers, and virtualization requirements. All relevant configuration, management, monitoring, and troubleshooting subsystems are made accessible directly through this CLI as opposed to exposing the Linux shell. Cisco WAAS devices can be configured to encrypt the data, swap, and spool partitions on the hard disk drives using encryption keys that are stored on and retrieved from the Central Manager.

Summary The Cisco Wide-Area Application Engine family includes three network modules for the Integrated Services Router and six appliance models spanning two desktop models and four rack-mount appliance models. By sizjng the recommended guidelines for performance and scalability, a robust Cisco WAAS design can be realized, thereby allowing administrators to deploy the solution confidently to improve application performance over the WAN while enabling centralization and consolidation of costly infrastructure.
It also looks at the licensing options for Cisco WAAS, positioning for each of the agchitecture platforms, and performance and scalability metrics anv each of the platforms. Additionally, the increased memory configuration provides support for a greater amount of WAN bandwidth and optimized TCP connections.
This license dictates what features are permitted to be configured on the device.
Both methods of integration and interception are discussed in Chapter 4. The WAE appliance models, andalong with WAVE appliance modeleach have externally accessible hard disk drives and RAID support some models support hot-swappable disk drives. The distinction between the two is that a WAVE device, available only as an appliance, can also provide branch office virtualization services in conjunction with WAN optimization and application acceleration.
The Cisco WAAS appliance family is arcgitecture to be deployed in a location of any size, including the small branch office, campus networks, or the largest of enterprise data center networks.
About Affiliates Cisco Systems, Inc. Keys are stored in the Central Manager database which can be encrypted and synchronized among all Central Manager devices for high availability. WAE appliance models andalong with WAVE appliance models, andare targeted toward branch office deployments, whereas the WAE appliance models, are targeted toward regional office and data center deployments. The Cisco WAAS router-integrated network modules are designed to provide optimization services for the remote branch office or enterprise edge.
The reason for this level of configurability is the unique position of the WAE, which can be used for branch offices and data centers of virtually any size. Licensing Next Section Previous Section. Additionally, the Enterprise license enables support for disk encryption and NetQoS integration. See All Related Articles. As flows are intercepted by the WAAS device and determined to be candidates for optimization, those flows are handed to the Application Traffic Policy ATP engine to identify what level of optimization and acceleration should be applied based on the configured policies and classifier matches.

Chapter Description This chapter provides an introduction to the Cisco WAAS hardware family, along with an in-depth examination of the hardware and software architecture. The current Cisco WAAS hardware family consists of three router-integrated network modules, two desktop appliance models, and four rack-mounted appliance models. With such a diverse hardware portfolio, Cisco WAAS can be deployed in each location with the appropriate amount of optimization capacity for the needs of the users or servers in that particular location.
The interface manager also provides management over logical interfaces that can be configured over physical interfaces. Chapter Description This chapter provides an introduction to the Cisco WAAS hardware family, along with an in-depth examination of the hardware and software architecture.
Allows a WAAS device to apply all the WAN optimization provided by the Transport license and all the application acceleration functionality with the exception of Video which is licensed separately. The alarm book which covers syslog messages, SNMP traps, and Central Manager dashboard alarmserror book which covers console messagesand product documentation can be downloaded from Cisco. About Affiliates Cisco Systems, Inc. This association is done by comparing the packet headers from each flow against a set of predefined, administratively configured, or dynamic classifiers, each with its own set of one or more match conditions.
The Cisco WAE model WAE is a dual-core processor rack-mount system that is designed for deployment in medium-sized branch office locations or medium-sized data center locations. The ATP also notes the application group to which the classifier belongs to route statistics gathered to the appropriate application group for proper charting visualization and reporting. The ISR is an ideal platform for the branch office in that it provides a converged service platform for the remote office, including routing, switching, wireless, voice, security, and WAN optimization in a single chassis platform, software version, and slot capacity dependent.
The WAE model is end-of-life and is not covered in this section; however, its performance and scalability metrics are covered in this chapter to support those who have already deployed these devices in their networks and wish to continue using them with WAAS v4.
It also looks at the licensing options for Cisco WAAS, positioning for each of the hardware platforms, and performance and scalability metrics for each of the platforms. Each WAAS appliance has expansion slots to support one or more additional feature cards, such as the inline bypass adapter, which has two two-port fail-to-wire pairs. The ATP is consulted only during the establishment of a new connection, which is identified through the presence of the TCP synchronize SYN flag which occurs within the first packet of the connection.
Flows that do not have a match with an existing classifier are considered “other” traffic and are handled according to the policy defined for other traffic, which indicates that there are no classifier matches and that the default policy should be used. Return to Beginning Previous Section.
