telecommunications and datacom (ICT) equipment; Part 2: Operated by -48 V direct current (dc)".

For the purposes of the present document, the following terms and definitions apply:

aggregation mode: mode in which, a few (typically higher bandwidth) ports on the equipment are considered UPLINK

ports; while majority (typically lower bandwidth) ports are considered user ports

NOTE: In this configuration the data flow is strictly from user ports to uplink ports and vice versa. User ports do

core mode: mode in which all ports are considered similar and have similar bandwidth

NOTE: In this configuration the data flow is so that each port communicate with one another.

maximum configuration: configuration with maximum capacity where whole slots of the equipment are configured

with maximum interface bandwidth line cards, all of the interfaces can work at the maximum data rate

Routers are typical packet switching equipment running at the network layer of OSI layer 3. The router selects the

optimal route according to the destination address of the received packet through a network and forwards the packet to

the next router. The last router is responsible for sending the packet to the destination host.

Routers connect different physical networks and manually configure and run standard protocols to obtain the

information of each subnet such as label, number of devices, names and addresses, etc. and thus generate and maintain a

live forwarding routing table. Based on this table, each IP packet passing these routers will be assigned an optimal path

according to the longest matching rules and be forwarded to the right path, if the path searching of the packet fails, this

The router can connect two or more independent and flexible logical networks using different data packets method and

media access method. Routers have not any requirements for hardware in each subnet but run the software using the

In light of the router different application scenarios, they can be classified into core routers, service routers, broadband

access routers, and aggregation routers (Core, Edge, access routers in ATIS 0600015.03.2009 [1] classification).

1) Provide multiple protocols on network layer to connect different types of networks.

2) Provide multiple types of interfaces so as to realize the conversion between the packets with different

4) Provide large-scale packet buffers so as to support QoS and traffic engineering.

5) Provide large-scale routing tables and support large-scale Layer 3 services within intra-networks or

Switches generally refer to equipment that exchange information in a communications system. They include Ethernet

switches, ATM switches, FDDI switches, and token ring switches, Ethernet switch is widely used because of fast

development of Ethernet technologies and its low costs, therefore, switches in the present document refer to Ethernet

Switches are typical packet switching devices at the data link layer of OSI layer 2. Based on the destination data link

layer addresses in the Layer 2 switching tables, each received packet, will be assigned an optimal path according to the

accurate matching rule and be forwarded to the right path, if the path searching of the packet fails, this packet will be

sent to the broadcast domain to which it belongs. The Layer 2 switching table is generated by switch network
