The logic is configured to communicate with a software-defined network (SDN) controller, store a look-up table in a first portion of the buffer memory, receive a packet using an ingress port of the apparatus, start an egress timer upon receipt of the packet, process the packet in order to finish processing prior to the egress timer expiring, determine an egress port for the packet, determine a packet size from information in a header of the packet when packet size information is available in the header, begin to route the packet via the egress port once the egress port is determined, and send the packet to the egress port upon expiration of the egress timer without further processing.

摘要： A distributed system includes first-tier entities, and a master entity in communication with each first-tier entity. The master entity provides a single access point through which an administrator can submit commands to manage all entities. The master entity maintains a table of virtual slots. Each virtual slot points to one of the first-tier entities, and each first-tier entity is pointed to by at least one virtual slot. The processor runs an RPC (remote procedure call) client to submit RPC requests to the first-tier entities, and determines a destination first-tier entity for a given RPC request in response to which virtual slot the administrator submits a command. The distributed system can include second-tier entities, each indirectly communicating with the master entity through a first-tier entity. The table has a virtual slot for each second-tier entity, which points to the first-tier entity acting as proxy for the second-tier entity.
