Architecture and Key Components
The SRX4100 and SRX4200 hardware and software architecture provides cost-effective security performance in a small 1 U form factor. Purpose-built to protect up to 40 Gbps Internet Mix (IMIX) firewall throughput network environments, the SRX4100 and SRX4200 incorporate multiple security services and networking functions on top of the industry-leading Juniper Networks Junos® operating system.
The SRX4100 supports up to 22 Gbps (IMIX) of firewall performance, 9 Gbps of next- generation firewall (application security, intrusion prevention, and logging), and 14.8 Gbps of IPsec VPN in data center, enterprise campus, and regional headquarter deployments with IMIX traffic patterns. The SRX4200 supports up to 44 Gbps of firewall performance, 18 Gbps of next-generation firewall, and up to 29.6 Gbps of IPsec VPN in data center, enterprise campus, and regional headquarter deployments with IMIX traffic patterns.
