FAQ

CISCO ASR9K, NCS55A2 & Juniper MX204 core router has been selected for the purpose of International Internet Gateway router with the high-speed routing and forwarding of Hundred Gigabit IP data from the INTERNET backbone network and support the QoS requirement of the IP service. CISCO ASR9K core router also can perfectly support the IP service, VPN service, intelligent routing and future MPLS network service.

This router is selected to satisfy the requirement of the increasing Internet service for backbone network equipment. With the carrier-level reliability, linear speed forwarding performance, perfect Diffserv/QoS mechanism, various service processing capabilities, and 8 slots for interface modules, this type of router is extremely suitable for the construction of Internet backbone network and WAN.

The products provide rapid rerouting and Virtual Routing Redundant Protocol (VRRP) of IP domains, support 50ms automatic protection switching (IPS) function of RPR ring networks and will provide the rapid rerouting technology of MPLS to further improve the equipment reliability.

The system is IPV6 compliant and meets all the capabilities required in the licensing guideline for International Gateway Router. The system offers 1+1 control redundancy and n+1 power redundancy. Also 1+1 circuit redundancy is available.

As a aggregation router CISCO NCS55A2, NCS5002 and & Juniper MX204 has been selected for the high speed routing and forwarding with the ISP operator. This router will maintain EBGP session with ISP Bot-tola Cyber Net. Registered Office: B/44, Sardar Market,Bottola, Khilkhet, Dhaka-1229, Bangladesh. Hotline: +8801912112112। Email: info@btcnbd.com operator to maintains a table of IP networks or 'prefixes' which designate network reach ability among autonomous systems (AS).

The system is IPV6 compliant and meets all the capabilities required in the licensing guideline for Aggregation layer. This router will primarily be used for connecting various ISPs through switchand even in direct if the bandwidth volume is high. This system will be able to switch traffic between local ISPs directly without going to the International Gateway Router. The system offers 1+1 control redundancy and n+1 power redundancy. Also 1+1 circuit redundancy is available.

Aggregation switch (Core) will be used for the connectivity of remote POP and at the same time this will be used for the ISP connectivity. All ISP will be connected in the switch port in different Plan. This switch will work as a redundant connectivity of every ISP. Security and filtering issue of the ISP will maintain in the switch port in initial stage.

For switch BTCN choose CISCO NEXUS, Juniper and Huawei. BTCN found Bandwidth Policy or Shaping CISCO is the best. We are using multiple cisco nexus switches.
