Cisco 7600 Wireless Security Gateway

Highly Scalable Wireless Security

The Cisco Wireless Security Gateway (WSG) was designed to address the huge scale requirements of modern mobile deployments. Deployed on a Cisco Service and Application Module for IP (SAMI) blade on a Cisco 7600 Series Router, each WSG service module supports 100,000 IPSec tunnels with a tunnel establishment rate of over 270 tunnels per second and full-duplex throughput of over 2Gbps

Important Features

The Cisco WSG provides secure tunneling for:

  • Femtocell deployments
  • Picocell deployments
  • Unlicensed Mobile Access (UMA)/Generic Access Network (GAN) traffic
  • 3G and 4G traffic

Key Innovations

The Cisco WSG:

  • Supports Internet Key Exchange 2 (IKE 2) which is required by 3GPP (3rd Generation Partnership Project) for Femtocell and UMA/GAN applications
  • Supports up to 8 SAMI blades for a maximum capacity of 800,000 IPsec tunnels, with a tunnel establishment rate of 2,160 tunnels/sec and full-duplex throughput of over 16Gbps

Key Services

  • Processes IKEv2 initialization requests from endpoints
  • Creates IPSec tunnels
  • Exchanges information with endpoints
  • Authenticates endpoints
  • Assigns IP addresses to endpoints
  • Does cryptographic algorithm negotiation
  • Rekeys security associations (SAs)
  • Does traffic selector negotiation
  • Supports network address translation (NAT) traversal
  • Encrypts, decrypts, authenticates, encapsulates, and decapsulates packets
