Abstract
The embodiments provide for a method of expanding a clustered service. The method includes inserting a network layer, comprising multiple switch devices, between switch devices of a network and switch devices of a clustered service, rearranging connections of the switch devices of the network and the switch devices of the clustered service to form a multi-chassis link aggregation group (MC-LAG), and maintaining data traffic during the rearranging the connections.

A method of expanding a clustered service, comprising:
- inserting a network layer, comprising multiple switch devices, between switch devices of a network and switch devices of a clustered service;
- rearranging connections of the switch devices of the network and the switch devices of the clustered service to form a multi-chassis link aggregation group (MC-LAG);
- and
- maintaining data traffic during the rearranging the connections.
A tangible, non-transitory, computer-readable media having instructions thereupon which, when executed by a processor, cause the processor to perform a method comprising:
- inserting a network layer, comprising multiple switch devices, between switch devices of a network and switch devices of a clustered service;
- rearranging connections of the switch devices of the network and the switch devices of the clustered service to form a multi-chassis link aggregation group (MC-LAG);
- and
- maintaining data traffic during the rearranging the connections.
An expandable clustered service, comprising:
- a plurality of service nodes, network connectable and each having one or more processors;
- switch devices configurable to couple to a network, switch devices coupled to the plurality of service nodes, and switch devices configurable to couple to the network switch devices and the plurality of service nodes switch devices;
- and
- the switch devices of the network, the switch devices of the service nodes and the switch devices coupled to the network switch devices and the plurality of service nodes switch devices configurable to perform a method comprising:
- inserting a network layer, comprising multiple switch devices, between switch devices of a network and switch devices of a clustered service;
- rearranging connections of the switch devices of the network and the switch devices of the clustered service to form a multi-chassis link aggregation group (MC-LAG);
- and
- maintaining data traffic during the rearranging the connections.
