We all know the parameters of the basic H3C router introduction. The parameters of the H3C router are closely related to the efficiency in use. Maybe you do not pay much attention to this aspect. I will give you some tips. 1. the most basic and important feature of the H3C router is packet forwarding. Forwarding packets at the same port rate is the greatest test of the router packet forwarding capability. Full-duplex line rate forwarding refers to the minimum packet length (Ethernet 64 bytes, POS port 40 bytes) and minimum packet interval (in accordance with the Protocol) bidirectional transmission on the vro port does not cause packet loss. This indicator is an important indicator of vro performance.
Ii. Number of available user slots www.2cto.com This indicator refers to the number of slots that can be used by users except CPU board, clock Board, and other necessary system boards and/or dedicated system board slots in a modular router. The maximum number of ports supported by the vro is calculated based on this indicator and the port density of the user board. 3. port throughput refers to the port packet forwarding capability, which is usually measured by pps: Packets per second. It is the packet forwarding capability of the router on a port. Generally, two interfaces with the same rate are used for testing. However, the test interface may be related to the interface location and relationship. For example, the throughput tested between ports on the same plug-in card may be different from the throughput value between ports on different plug-in cards.
4. In addition to using the destination address as the basis for route selection, a policy-based Router can also select a path for data packets based on the TOS field, source, and destination port number (high-level application protocol. Policy routing can implement traffic engineering to a certain extent, so that streams of different service quality or data of different nature (voice, FTP) go through different paths. 5. A memory router may contain multiple types of memory, such as Flash and DRAM. The memory is used for storage configuration, router operating system, and routing protocol software. In the middle and low-end routers, the route table may be stored in the memory. Generally, the larger the vro memory, the better, but the memory does not directly reflect the performance and capabilities of the vro, because efficient algorithms and excellent software may greatly save the memory.
6. CPU is the heart of a router, whether in a low-end or high-end router. In low-end and Middle-end routers, the CPU is responsible for exchanging route information, querying route tables, and forwarding data packets. In the preceding vro, the CPU capability directly affects the throughput and route computing capability of the vro. In high-end vrouters, packet forwarding and query are usually completed by the ASIC chip, the CPU only implements routing protocols, computing routes, and distribution route tables. Due to the technological development of www.2cto.com, many work on routers can be implemented by hardware, and the CPU performance does not fully reflect the performance of routers. The performance of a vro。 is determined by indicators such as the throughput, latency, and route computing capability of the vro.
VII. H3C Routing Information Protocol (RIP) is a distance vector-based routing protocol that uses Hops as the Metering Standard. RIP is an internal gateway protocol. Due to its simple implementation, RIP is the most widely used routing protocol. 8. Distance Vector Multicast Routing Protocol DVMRP is a distance vector-based multicast routing protocol, which is basically developed based on RIP. DVMRP uses IGMP to exchange routes with neighbors
9. interface types the types of interfaces supported by vrouters reflect the versatility of vrouters. common interfaces include: universal Serial Interface (through cable conversion to RS 232 DTE/DCE interface, V.35 DTE/DCE interface, X.21 DTE/DCE interface, RS 449 DTE/DCE interface and EIA530 DTE Interface) 10 M Ethernet interface, Fast Ethernet interface, 10/100 adaptive Ethernet interface, Gigabit Ethernet interface, ATM interface (2 M, 25 M, 155 M, 633M, etc), POS interfaces (155 M, 622M, etc.), licensing ring interfaces, FDDI interfaces, E1/T1 interfaces, E3/T3 interfaces, and ISDN interfaces. The above is an introduction to H3C router parameters. If you want to select a vro suitable for your network, you can refer to the comparison. This article is from
