1 Clarifications No. 1 to the Queries (Commercial/Technical) Received from the Bidders (13th August 2012) (Tender No. NDCL/28/ for Supply, Delivery, Installation and Commissioning of Internet Traffic Management System (ITMS)) NOTE: Bidder shall include the compliance statement on all the clarifications. Bidder shall submit the Clarifications along with their bid document and shall be considered for the evaluation. Non Submission of the clarification with the compliance statement shall result in the rejection of the Bid. 1 VIII VIII VIII Administration and MAINTENANCE SYSTEM Training: (6) Details of ITMS and Policy Server Integration in ADSL and Mobile Network The offered ITMS shall have expansion slot to increase throughput in multiple of 5/10Gbps. ITMS Shall Support following IPv6 transitioning Technique: NAT-PT Tunneling Dual Stack approach NTC is requested to share which access is considered for mobile network here LTE, WiMax, 2G/3G, 3GPP2 etc. with complete network architecture diagram of all access technologies for which ITMS solution is required. Traffic split and subscriber growth (YoY) with enterprise and retail split to be provided as well per access. Please clarify the maximum supported throughput on the solution required and over which interval of time. Kindly share an excel sheet with inputs on YoY throughput growth and subscriber growth. These inputs will be helpful for all vendors to do the dimensioning and pricing accurately. What is the approach NTC is going to follow for IPv6? When would you need end to end IPv6 in the networks? Are you planning to deploy CG NAT in the network? Kindly share the complete IPv6 framework expected? The Clause is related to training and not for the implementation right now. But the implementation of proposed system can be extended for mobile network in future. Please refer to clause No of VIII, chapter 2. scalability shall be upto 20 Gbps and can be upgrade by 5Gbps or 10Gbps Clause itself is clear. The core Network is already been live as IPv6 so the proposed system need to have IPv6 enabled from day 1. We do have CG NAT in existinng Network. The frame work will be shared during the scoping of the project implementation to decide the scenario.

2 4 VIII VIII VIII VIII It shall supports over 1600 applications, Protocols and applications are more than Please refer to clause No 2.5, 6.7, 7.2 of services, and protocol signatures. Updates can Suggest adding a sentence here that all relevant VIII, chapter 2 be installed without affecting uptime or traffic. protocols required for your retail customers in 2G, 3G, WiMax, DSL, Wifi, FTTH networks should be supported. These Protocols and signatures change very frequently on the internet. It is very important to keep a regular track of these new and changing applications and their signatures and it should not be limited to a number as it is going to grow over a period of time. To start with the intent should be to seek support for applications normally used by the retail subscribers in Busy Hour for effective traffic management. It shall analyze the asymmetric traffic with true Request NTC to share the end to end network clause it self is clear. accuracy and support synchronizing traffic flows architecture diagram to understand level of with extraordinarily low overhead (1-5% of total asymmetry in the network and provide a fool proof traffic volume). solution. Also request NTC to ask for performance impacts in terms of no. of flows supported per box with additional boxes into the system introduced in the cluster in order to handle throughput and remove asymmetry. Intent would be to remove asymmetry with no performance impact and increased support for no. of flows with addition of boxes into the cluster. The solution shall have dynamic volume based quota control in hourly, daily, weekly and monthly basis with different QOS on peak and non-peak hours. NTC requires a full blown Quota manager to main Quota per subscriber into the solution proposed or an interface towards existing OCS which will handle the Quota and interact with inline device to implement policies. Please confirm which vendor quota manager you are using. This is required to evaluate the integration requirements. Adds data to packet headers to determine how Request NTC to coarsely define the use case of Clause itself is clear. data streams are treated or in some cases, traffic enrichment with an example. what sort of stream might be sent. Operators might use this to vary the format of content according to the capabilities of the receiving device (e.g., mobile phone vs. PC). OCS of AILK - CRTB support DAIMETER for Connectivity.

3 8 VIII VIII VIII VIII VIII VIII VIII It supports RegEx, Range Hash Architecture for better detection performance. Fail to understand this requirement. Detection capability will depend on whether the signatures on the applications are defined accurately to understand a particular application or flow. If signature identification is wrong any algorithm used for detection would fail. Request NTC to remove this requirement and use application detection capability based on signatures. The system shall be based on Pearson s Chi- Request NTC to explain the significance of Clause itself is clear. Square test and agnostic to VoIP-related traffic requirement stated in the clause.

The offered system shall also be able to make a analysis for the proprietary technology and protocol and standards like Huawei, CISCO and many more The offered System shall have functionality to analyze the protocol behavior based on IETF and ITU standard along with some vendor specific protocol adopted with Equipment in NT network The offered system shall have the flexibility to handle as much as high traffic of NT that will increase within the 5 year. Bidder shall provide license fee for interface to OCS (optional). Request NTC to share vendor and product names with versions of all the components of all access technologies for which integration will be required like PCRF, OCS and AAA etc. Request NTC to detail out the applications for which support is required. Request NTC to provide the following year on year (for 5 years) Subscriber growth, throughput, application use cases and service offering etc.. Also request NTC to share the exact split of retail subscribers with their service offerings on a year on year basis. NTC is also requested to provide this information per access technology clearly highlighting the access type. This will be helpful for accurately pricing the quote. Does NTC expect Vendor to do Quota management or it needs an interface to OCS to do that. clause is important for optimizing duration for detection and assembling the related session packet data. please refer to clause No 19.1 of VIII, chapter 2 Clause itself is clear. Please refer to clause No 1.1, 19.1 of VIII, chapter 2 license fee for interfacing with the exisiting AILK-CRTB OCS using DIAMETER.
