Intel Corp. this week introduced five NetStructure appliances designed to streamline Internet traffic management and performance. Intel has announced NetStructure 1520 Cache, which helps service providers build intelligence into caching hierarchies, and Intel NetStructure 7115 e-commerce Accelerator, which boosts traffic speed by offloading encryption and decryption of Internet transactions. NetStructure 7185 e-commerce Director, meanwhile, speeds up SSL (Secure Sockets Layer) transactions. NetStructure 7145 Traffic Director makes priority delivery decisions based on response times for server-farm performance. The product works with NetStructure 7175 Traffic Director, which adds Layer 7 traffic management to NetStructure 7145, to help reduce error messages during peak traffic periods.
