Summary:To achieve a trial frequency according to the nature of each access to a common memory for internal process in a transmission system in which each transmission apparatus has a common memory.SOLUTION: The transmission apparatus includes: a common memory; a first processing unit which accesses the common memory when performing data transmission/reception to/from another transmission apparatus; a second processing unit which accesses the common memory for internal processing; an arbitration unit which, when the first processing unit is not accessing the common memory, permits accessing from the second processing unit to the common memory, whereas when the first processing unit is accessing the common memory, does not permit accessing from the second processing unit to the common memory; and a notification unit which notifies the second processing unit of a network configuration information transmission time zone. An access trial frequency to the common memory is different dependent on the network configuration information transmission time zone and a control data transmission time zone.SELECTED DRAWING: Figure 2 【課題】各伝送装置がコモンメモリを備える伝送システムにおいて、内部処理のためのコモンメモリへのアクセスごとの性質に応じたトライ頻度を実現する。【解決手段】実施形態の伝送装置は、コモンメモリと、他の伝送装置とデータの送受信を行うときにコモンメモリにアクセスする第1の処理部と、内部処理のためにコモンメモリにアクセスする第2の処理部と、第1の処理部がコモンメモリにアクセスしていないときは第2の処理部によるコモンメモリへのアクセスを許可し、第1の処理部がコモンメモリにアクセスしているときは第2の処理部によるコモンメモリへのアクセスを許可しない調停部と、ネットワーク構成情報伝送時間帯であることを第2の処理部に対して通知する通知部と、を備える。ネットワーク構成情報伝送時間帯と制御データ伝送時間帯で、コモンメモリに対するアクセスのトライ頻度が異なる。【選択図】図2
