Abstract: Embodiments include a method and system for coordinating cache management for an exclusive cache hierarchy. The method and system may include managing, by a coordinated cache logic section, a level three (L3) cache, a level two (L2) cache, and/or a level one (L1) cache. Managing the L3 cache and the L2 cache may include coordinating a cache block replacement policy among the L3 cache and the L2 cache by filtering data with lower reuse probability from data with higher reuse probability. The method and system may include tracking reuse patterns of demand requests separately from reuse patterns of prefetch requests. Accordingly, a coordinated cache management policy may be built across multiple levels of a cache hierarchy, rather than a cache replacement policy within one cache level. Higher-level cache behavior may be used to guide lower-level cache allocation, bringing greater visibility of cache behavior to exclusive last level caches (LLCs).

Abstract: A system for creating a session entry and forwarding an IP packet includes memories that store session and session template tables, and first and second processors in communication with the memories. When the first processor receives the IP packet, it determines whether the session table includes a session entry corresponding to the IP packet. If the session table does not include the session entry, the first processor determines whether the session template table includes a session template entry corresponding to the IP packet. The first processor generates the session entry using the session template entry and the IP packet. If the session template table does not include the session template entry, the first processor forwards the IP packet to the second processor, which generates the session template entry and the session entry.
