Network Switch Test


이번에 자체적으로 만든 네트워크 기반의 방송 시스템 테스트 화면입니다

네트워크 상에서 Audio와 비디오 모두 동기를 맞추어서 전송하는 것이 목적입니다.


네트워크 상에서 많은 수의 터미널을 붙여도 전체 터미널의 동기화에 문제가 없이 운영되는 것이 포인트입니다.





Switch : L2 Managed Switch with 2 Bypass ports


• DHCP client
• DHCP relay including option82
• Loop Protection
• LLDP Support
• QOS Support
• 802.1Q VLAN switch with 8K MACs and 4K VLANs
• Push/pop up to two VLAN tags
• IPv4/IPv6 multicast
• Policing with storm control
• RSTP support
• Hardware and software-based learning
• Link aggregation (IEEE 802.3ad)
• Independent and shared VLAN learning
• Jumbo frame support
• Dual bypass relay to mitigate powerless scenario
• 12-port
l 100M 8-ports with POE

l Gigabit 4-ports

• Bypass 

  - 2 Port

  - Fail-safe access and network operations
