Thiết bị chuyển mạch EX9251-8X4C-DC là thiết bị core với kích thước nhỏ gọn, có thể lập trình và mở rộng cho môi trường doanh nghiệp, giảm chi phí và độ phức tạp. Juniper EX9251-8X4C-DC đơn giản hóa đáng kể các kiến trúc trung tâm dữ liệu với Junos Fusion Enterprise và Ethernet VPN, tạo đường dẫn core 100GbE.
| View Datasheet EX9251-8X4C-DC |
EX9251-8X4C-DC hỗ trợ các ứng dụng lớp 2 hoặc lớp 3 bằng cách kết hợp các công nghệ Ethernet VPN (EVPN) và LAN mở rộng ảo (VXLAN). Sử dụng các công nghệ mở này cho phép doanh nghiệp tạo ra một mạng kết nối chặt chẽ, xuyên suốt từ khắp các địa điểm phân tán nhưng vẫn có thể phân khúc lưu lượng.
