Product Overview
To meet the growing demand from homes and businesses for high-performance broadband access services, manufacturers must develop new networking products that are capable of provisioning rich services. The Intel® IXP425 network processors are designed to meet the needs of last-mile applications, such as customer premises equipment, and mini-DSLAMs for multi-dwelling units (MxUs). These network processors deliver wire-speed performance and sufficient "processor headroom" for manufacturers to add a variety of rich software services to support their networking applications.
