摘要
Methods and systems for data communication are disclosed and may include utilizing a multi-level lookup process for determining IPsec parameters from a security association database. The security association database may be stored in content addressable memory, and may include an Internet protocol address table, a security association lookup table, and a security association context table. The security association lookup and security association context tables may include a single table. An Internet protocol address table index may be looked up in the Internet protocol address table for a first lookup of the multi-level lookup process. A security protocol index may be looked up utilizing the Internet protocol address table index for a second lookup of the multi-level lookup process. The Internet protocol security parameters may be determined utilizing the security protocol index. IPsec processing may be performed utilizing the determined Internet protocol security parameters.
