Cisco3845-AA-K9, Cisco 3845 Basic Wan Optimization Bundle.
The Cisco WAN optimization solutions offer the industry's most integrated, yet flexible and cost-effective bandwidth management solutions. An integrated services solution in the branch router is the logical point of consolidation for WAN optimization technologies, such as compression, caching, wide-area application services, quality of service (QoS), and access control, because it sits at the WAN/LAN interface where bottlenecks can efficiently be mitigated and critical network services (voice over IP [VoIP], security, QoS, and Multiprotocol Label Switching [MPLS]) need to be deployed. Cisco Layer 2 integrated compression, combined with a content engine object and sequence caching module, provide WAN bandwidth management that improves application response time on congested links by reducing the amount of data sent across the WAN. Layer 2 compression provides many benefits over standalone compression appliances by providing a tightly integrated solution that interoperates with critical Cisco IOS Software features and services such as QoS, policy-based routing (PBR), network-based application recognition (NBAR), Network Address Translation (NAT), and access control lists (ACLs).
The Cisco WAN optimization solution presents many benefits over external, standalone appliances, including superior integration with security, voice, and QoS technologies, as well as integrated management and maintenance. Other key benefits include:
• Layer 2 and Layer 3 payload compression and hardware acceleration
• HTTP, FTP, Multimedia Message Service (MMS), Real Time Streaming Protocol (RTSP), common Internet file system (CIFS), and Network File System (NFS) caching and TCP/IP optimization
• QoS, NBAR application-level traffic classification, and bandwidth estimation
• URL and traffic filtering
• VoIP compression techniques (codec compression, Real-Time Transport Protocol (RTP) header compression, and voice activity detection)
• Remote Monitoring (RMON-II) and diagnostic capabilities
• Multilink route optimization such as Cisco Optimized Edge Routing (OER) and PBR
