Toshiba Corp has entered the increasingly crowded Internet protocol switching market with its Cell Switch Router 5300, a high-speed Internet protocol switch. According to Toshiba, the switch combines ATM Asynchronous Transfer Mode cell switching with network-layer packet switching and is capable of transmitting up to 4.2m data packets per second. The company also claims that unlike rival products available from Ipsilon Networks Inc, the CSR 5300 can work with the existing ATM infrastructure by using the ATM Forum’s User-to-Network Interface 3.0 and 3.1 signaling specification. Both switches are similar in that they detect Internet Protocol flows to provide cut-through switching of packets. Toshiba says that it will extend support in the CSR 5300 for the Ipsilon Flow Management Protocol that would allow it to co-exist with Internet protocol switching networks. The CSR 5300 is due to be made available in May of this year. Toshiba says that pricing for the switch has not yet been set.
