Title: Emulated LAN (ELAN) including specifying ports of a service member set and flooding a packet to the permitted members of the set.
Inventor: GLEESON MAURICE
IPC: H04L12/46
Filed: 2008-07-12
Abstract: A switch which provides ELAN emulation including the specification of ports in a service member set is adapted to remove a particular selected port from the service member set and to transfer connectivity of destinations previously associated with that port to another port. In response to a (MAC address) lookup which yields an ELAN (Emulated LAN) unicast which identifies the particular port, the switch floods the packet to all the other permitted members of the service member set. The aforementioned transfer may occur either by imposing a reconfiguration of the service member set or may occur by the operation of a spanning tree protocol. In both circumstances the present invention allows more efficient operation of the switch and in particular by the emulation of table flushing than its performance by software.

Title: Reducing back invalidation transactions from a snoop filter
Inventor: KURTS TSVIKA
IPC: G06F12/08
Filed: 2009-05-27
Abstract: A multiprocessor system (10) comprise caching agents (17), e.g. processor nodes, each having local cache (12). Chipset (13) includes coherency controller 132 having inclusive snoop filter 24, providing coherency information of cache lines in caches (12), which is associated with staging pool 28. During operation, a cache (12) may determine it needs to evict one or more cache lines. To do so, caching agent (17) sends a capacity eviction transaction to snoop filter 24. If snoop filter 24 determines that an invalidating writeback transaction is likely to be issued by caching agent for a line to be evicted, then snoop filter 24 moves a filter entry, corresponding to the line to be evicted, to staging pool 28. Then, if an invalidating writeback transaction is received from the agent within a predetermined time period (from when the entry was moved to staging area 28) then the entry is deleted from pool 28 without transmission of a back invalidation request from filter 24 to agent (17).
