CHỨC NĂNG NHIỆM VỤ CÁC CARD SRP: Switch Route Processor bao gồm 2 card Fabric Board

và Processor Board• Chuyển mạch gói IP giữa các port vào và ra• Cấu hình và điều khiển cơ cấu chuyển mạch• Khởi động hệ thống, quản lý quạt, nhiệt độ, nguồn cung cấp• Lưu trữ phần mềm, cấu hình hệ thống trên card nhớ NVS

Flash và nạp phần mềm cho các Line Module• Quản lý bảng định tuyến, trạng thái các đường kết nối, phân

phối các bảng định tuyến tới các line module

Line Module• Xử lý lưu lượng các gói dữ liệu (QoS) và chuyển gói sang

SRP• Điều khiển IO card

IO Card• Giao tiếp với các thiết bị bên ngoài, cung cấp các kết nối giữa

ERX và mạng.
