Abstract: Systems and methods for increasing bandwidth in a computer network are provided. A computer network can include a first lower level switch, first and second upper level switches, and first and second passive optical splitters, and a mirror. The first passive optical splitter can have a first port directly coupled to the first upper level switch, a second port directly coupled to the second upper level switch. The second passive optical splitter can have a port directly coupled to a port of the first passive optical splitter, and a port directly coupled to the first lower level switch. The mirror can be coupled to a port of the second passive optical splitter and reflect an optical signal received from the second passive optical splitter to the first upper level switch and second upper level switch through the second passive optical splitter and the first passive optical splitter.

Abstract: Aspects and implementations of the present disclosure are directed to a network device storing an address table. Each of the address table entries is assigned to a respective provisioned index value and an instance of a distributed service. The device is configured to add a new service instance to the address table by obtaining an assignable index value for the new service instance, identifying an assigned index value that is a companion index value to the obtained index value, dividing a packet source address set associated with the companion index value into first and second address subsets, and assigning the first address subset to the service instance entry in the address table associated with the assigned companion index value and the second address subset to an entry in the address table associated with the obtained index value and the newly added service instance.
