description To provide a communication system capable of flexibly and swiftly configuring and changing network slices.SOLUTION: In a communication system 1, an SLG 6 includes: a slice selection part 614 that is configured so as to, when receiving a network slice reservation request including the network conditions from vCPE3, select a destination SLG of the network slice that satisfies network conditions on the basis of the topology information, delay status and processing capacity information about each of other SLGs 6, and to reserve the network slice, and when there is no destination SLG that satisfies the network conditions, to start a new destination SLG and establish a network slice that satisfies network conditions; and a distribution part 63 that distributes the traffic transmitted from vCPE to the network slice reserved or established by the selection part.SELECTED DRAWING: Figure 2 【課題】ネットワークスライスの設定や変更を柔軟かつ迅速に実行可能である。【解決手段】通信システム1において、SLG6は、vCPE3からネットワーク条件を含むネットワークスライス確保要求を受けると、他の各SLG6に関するトポロジー情報、遅延状態及び処理能力情報を基に、ネットワーク条件を満たすネットワークスライスの宛先SLGを選定してネットワークスライスを確保し、ネットワーク条件を満たす宛先SLGが無い場合には、新規に宛先SLGを起動させてネットワーク条件を満たすネットワークスライスを確立するスライス選定部614と、vCPEから送信されたトラヒックを、選定部が確保または確立したネットワークスライスに振り分ける振分部63と、を有する。【選択図】図2
