To keep things simple, we illustrate the examples with the typical in-line deployment in Site B offices and out-of-path deployment at
Site A. However,
Site B offices are not restricted to in-line deployment, nor is
Site A restricted to out-of-path deployments.
“Fundamentals of Deploying WAN Optimization,” describes some of the fundamental concepts of deploying WAN acceleration in enterprise networks. It provides an overview and introduction to common installation models, pros and cons of each, and recommendations.
“In-Line Deployment,” describes the procedures for an in-line deployment where the Silver Peak Appliance sits between the WAN router and the Ethernet switch.
“Out-of-Path with Policy-Based-Routing Redirection,”, describes the procedures for a scenario that deploys the
Site B location in-line and the
Site A network out-of-path with an available spare router port and uses Policy-Based Routing (PBR) on the WAN router to redirect traffic to the Silver Peak appliance.
“Out-of-Path with WCCP,” (Comparing Subnet Sharing & TCP/IP-based Auto-Optimization), describes the procedures for setting up Web Cache Communications Protocol (WCCP) service. The example uses a Cisco router paired with a single Silver Peak appliance deployed out-of-path (Router mode). It also highlights the differences in traffic redirection required when using subnet sharing, as opposed to TCP-based or IP-based auto-optimization.
“Out-of-Path with VRRP Peering to a WAN Router,” describes the procedures for a scenario where the Silver Peak appliance uses the Virtual Router Redundancy Protocol (VRRP) to peer with the existing router, when no spare router port is available.
“Out-of-Path with PBR and VRRP Redundant Silver Peak Appliances,” describes the procedures for setting up high availability. In this example, Site A deploys a primary and a secondary appliance out-of-path (Router mode), and the
Site B location deploys the appliance in-line (Bridge mode). Additionally, the peered
Site A appliances use the Virtual Router Redundancy Protocol (VRRP) to create and share a common IP address, called the Virtual IP address (VIP).
“Out-of-Path with WCCP Redundant (Active/Active) Appliances,” describes the procedures for setting up high availability by using Web Cache Communications Protocol with a Cisco router and redundant Silver Peak appliances in an out-of-path deployment.
