Cisco WAAS is available as WAAS Mobile, WAAS Express, WAAS ISR modules, WAAS on SRE for ISR G2, WAASappliances, vWAAS, and WAAS PC.

Cisco WAAS is available as WAAS Mobile, WAAS Express, WAAS ISR modules, WAAS on SRE for ISRG2, WAAS appliances, and vWAAS.

Cisco WAAS is available as WAAS Mobile, WAAS Express, WAAS ISR modules, WAAS on SRE for ISR G2, WAAS appliances, vWAAS, WAAS PC, and WAAS Server.

Cisco WAAS is available as WAAS Mobile, WAAS Express, WAAS ISR modules, WAAS appliances, and vWAAS.

Cisco WAAS is available as WAAS Express, WAAS ISR modules, WAAS on SRE for ISR G2, WAAS appliances, vWAAS, and WAAS PC.?

The main services of the access layer include physical connectivity to endpoints, automatic endpoint discovery, and port-based security features.

Due to the high number of ports, performance is one of the key features that is required at the access layer.

The distribution layer is commonly the first routing hop.

Scalability, high availability, and fast convergence are typical requirements for the core layer.

The core layer provides aggregation services to the access layer.

The exponential growth in bandwidth requirements and increased sensitivity to latency can be addressed by Cisco WAAS.

Transcoding services in a video and collaboration deployment can be provided in Cisco IOS software, so no hardware DSPs are required on the Cisco 3900 router series.

Cloud-based managed security is supported by the built-in ScanSafe Connector.

Cisco Unified Communications Manager Express can run on Cisco UCS Express.

TFO

DRE with persistent cache?

Application optimizers?

Auto-discovery of end nodes?

Juniper Networks is the strongest competitor in the high-end and SOHO markets.

AVM is one of the largest Cisco competitors in Germany.

Most competitors have a similar architectural approach to Cisco.

Larger competitors to Cisco include Juniper Networks, Riverbed, and Huawei.

Cisco has a market share of about 70% in the Layer 2 and Layer 3 managed switch market.

HP is one of the strongest competitors with a market share of about 20%.

Most of the competitors offer me-too point products only; they lack an overall solution framework similar to the Cisco Borderless Network.?

Juniper has a market share of less than 3%.

Competitors efficiently support the BYOD solution.

CVD is technology-oriented, while SBA ismarket- and solution-oriented.

SBA guides are available for enterprise deployments only.

SBA is a blueprint for delivering the three Cisco architectures in a modular approach.

Gold partners have access to a demo lab for each validated design.

Cisco MediaNet Performance Monitor collects performance metrics of video traffic as flexible netflow records which can be processed by any netflow collector, such asCisco Prime Assurance Manager.

Cisco MediaNet supports only SNMP traps but not syslog messages.

When using PVDM3 on Cisco ISR G2, video streams of the same type can be locally mixed within the router. Video transcoding servicesrequire a dedicated video MCU.

Cisco MediaNet Mediatrace allows real-time troubleshooting by providing details about every hop of the end-to-end path of your mediastream.

3G, 4G, and satellite connections are commonly used as backup links in high-end branches.

The standard branch typically uses MPLS as a primary link and any kind of Internet link(DSL, cable, etc.) for backup.

HD video traffic is found in high-end and ultra high-end branches.

WAAS Express is the preferred WAN optimization implementation in mobile and standard branches.
