ERNET network is extensively monitored. As a passive measurement, SNMP interface statistics, both bytes and packets per second are recorded and viewed by modified MRTG graphs.
ERNET PoPs continuously monitor the performance of peering, backbone and user links. The measurement includes :
The services for which we measure the performance metrics include web, ftp, e-mail ets. The web download session throughputs obtained by the users at the user site are measured. ERNET India generates monthly statistics for :
ERNIC (ERNET Network Information Centre)
ERNIC provides Internet Protocol (IP address space (both IPv4 & IPv6) and in-addr.arpa domain delegations to its customers. The various activities performed by ERNIC include :
IP Addresses Allocated to ERNET India
1. IPv4 Address
2. IPv6 addresses
IP address allocation policy
i) For New & Existing Users:
|S. No.||Bandwidth||IPv4 Allocation||Extended IPv4 Allocation as per necessity|
|1.||Less than 10 Mbps||/28 (16 IP addresses)||/27(32 IP addresses)|
|2.||10 Mbps to less than 34 Mbps||/27 (32 IP addresses)||/26 (64 IP addresses)|
|3.||34 Mbps to less than 45 Mbps||/26 (64 IP addresses)||-|
|4.||45 Mbps to less than 100 Mbps||/25 (128 IP addresses)||-|
|5.||100 Mbps and above||/24 (256 IP addresses)||-|
(ii) Irrespective of the bandwidth taken , the Organizations / Institutes which are having ERNET India PoPs , may be provided /24 ( 256 IP addresses) with the approval of Competent Authority. However, the Organization / Institute should be connected to ERNET network as required by APNIC policy. They may be requested to upgrade the bandwidth in view of the revision in internet bandwidth tariffs.
3. Apart from this the user shall be allocated IP’s based on the following conditions:
Within the Internet, an autonomous system (AS) is a collection of connected Internet Protocol (IP) routing prefixes under the control of one or more network operators that presents a common, clearly defined routing policy to the Internet.
Originally, the definition required control by a single entity, typically an Internet service provider or a very large organization with independent connections to multiple networks, that adhere to a single and clearly defined routing policy, as originally defined in RFC 1771.The newer definition in RFC 1930 came into use because multiple organizations can run BGP using private AS numbers to an ISP that connects all those organizations to the Internet. Even though there may be multiple Autonomous Systems supported by the ISP, the Internet only sees the routing policy of the ISP. That ISP must have an officially registered Autonomous System Number(ASN).
A unique ASN is allocated to each AS for use in BGP routing. AS numbers are important because the ASN uniquely identifies each network on the Internet.
The ERNET network uses AS number 2697 and for BGP peering with external network. ERNET recommends that any organisation that connects to more than one transit provider should take a public AS number from APNIC.
