Evaluate network device

Requirement of network device for video surveillance network.

1, Managed Switching HUB. (Layer 2 SW).

2, Support wire speed.

3, Port-Mirroring for network performance investigation. 4, Furnish SNMP for easy maintenance.


A switch is said to work at "wire speed" if it has enough processing power to handle full ethernet speed at minimum packet sizes (64byte). Most switches on the market are well ahead of network traffic capabilities supporting full "wire speed" of ethernet, 148,810 pps (packets per second) at 100Mbps, and 1,488,100 pps at 1Gbps.

About wire speed

148,810pps

Minimum packet 64byte + 20 byte =84 byte = 672 bit100Mbps = 100,000,000bps / 672 bit = 148,810 pps1Gbps = 1,000,000,000bps / 672 bit = 1,488,100 pps

100Mbps 1Gbps24ports

1,488,100pps

148,810pps(100Mbps) x Number of port (24) = 3,571,440pps1,488,100pps (100Mbps) x Number of port (2) = 2,976,200ppsTotal = 6,547,640 (6.5Mpps)


Cisco 2960 specification sheet



"port mirroring", which is a feature that enables switches to forward any packet to one PC and allows the network manager to determine the location of a problem on his network simply and efficiently. Port Mirroring is configured by assigning a port (called "management port") from which to copy all frames, and a port to which to send those frames. Finally, when the feature is activated, all frames bound for or sourced from the selected source port will be copied and sent (in addition to their regular destinations) to the selected destination port. Simply by placing a sniffer or ethereal on this destination port, each segment can be separately monitored without moving the equipment. By using this feature, you will able to monitor the entire LAN segment.

About Port Mirroring

The Simple Network Management Protocol (SNMP) is an application layer protocol that facilitates the exchange of management information between network devices. It is part of the Transmission Control Protocol/Internet Protocol (TCP/IP) protocol suite. SNMP enables network administrators to manage network performance, find and solve network problems, and plan for network growth.

DNS translates Internet domain and host names to IP addresses. DNS automatically converts the names we type in our Web browser address bar to the IP addresses of Web servers hosting those sites.

DDNS is a service that maps Internet domain names to IP addresses. DDNS serves a similar purpose to DNS: Support under DHCP network configuration.

DHCP allows a computer to join an IP-based network without having a pre-configured IP address. DHCP is a protocol that assigns unique IP addresses to devices, then releases and renews these addresses as devices leave and re-join the network.
