An annular gas turbine engine combustor liner has a single piece annular shell circumscribed about a first axis of revolution. The shell has a hot side and a cold side, an annular dilution hole section, and a plurality of asymmetrical cylindrical dilution holes extending through the section. Pockets
An annular gas turbine engine combustor liner has a single piece annular shell circumscribed about a first axis of revolution. The shell has a hot side and a cold side, an annular dilution hole section, and a plurality of asymmetrical cylindrical dilution holes extending through the section. Pockets are circumferentially interdigitated between the dilution holes and extend into the shell from the cold side such that the pockets form dilution hole bosses between the pockets through which the dilution holes extend. Each of the dilution holes is circumscribed about a second axis of revolution which is not parallel to the first axis of revolution. The liner may further include forward and aft annular cooling nuggets located forward and aft of the dilution hole section and having annular film cooling slots which are open in the axially aftwardly direction. The shell is machined from a single piece integrally formed near net shape form such as a forging, a casting, or more particularly a spin or centrifugal casting. The invention includes a method for making the annular gas turbine engine combustor liner by forming a single piece integrally formed near net shape form and machining it to produce the shell and the above features in the shell.

The name caching entity of claim 1, wherein said name caching entity is a bridge. 5. The name caching entity of claim 1, wherein said name caching entity is a local area network (LAN) switch. 6. The name caching entity of claim 1, wherein said data communication network comprises an asynchronous transfer mode (ATM) emulated local are network (LAN) and said name caching entity is a LAN emulation server and broadcast and unknown server (LES/BUS). 7. A data communication network, comprising a network client; a network server coupled to said data communication network by a plurality of network adapters sharing a common logical name, said plurality of network adapters each having a different network address; a name caching entity located between said network client and said network server, said name caching entity including; a name cache; means for storing in said name cache said common logical name in association with a network address of one of said plurality of network adapters; means for converting broadcast frames to unicast frames by reference to said name cache; wherein said means for converting frames includes, means, responsive to receipt of a broadcast frame specifying a logical name, for searching said name cache for said logical name; and means, responsive to locating said logical name in said name cache, for inserting a network address associated with said logical name by said name cache into said broadcast frame to convert said broadcast frame into a unicast frame; and means for disassociating said logical name and said network address in said name cache in response to a failure to detect a frame indicating the establishment of a session with said network server within a selected interval of transmission of a frame requesting establishment of a session with said network server. 8.
