Internet access including IP address allocation, domain registration, domain name service, web site hosting, e-mail accounts, router management and technical support. Fees vary by month, year and/or one-time.
Provision of Internet access to districts, schools and other educational entities. To ensure optimal security, ESC-20 uses multiple devices to secure and manage bandwidth. These devices detect and eliminate the most damaging threats such as viruses, worms, intrusions, in real time without degrading network performance. They monitor and shape traffic in real-time to maximize application throughput across the network infrastructure. In addition to securing Internet traffic, ESC-20 can assist in identifying security threats and securing internal networks from intrusion by evaluating various security measures.
In designing Internet access, ESC-20 has chosen a standard set of equipment, protocols and other elements to reduce the complexity in deploying and maintaining the wide area network. These choices have also been made with the intention of evolving Internet access from conventional routing to high speed Ethernet switching as part of the ESC-20's long-term strategy to increase capacity and efficiency. This design also has the flexibility to provide advanced data services and mainframe resources from ESC-20 in the future with minimum changes to the basic equipment required for Internet access.
As part of the Internet access, clients will receive an access port, IP address and technical support.
ESC-20 will provide a dedicated port at the ESC-20 hub for T-1 or GigaMAN level access to the wide area network. Additional ports may be secured by the client as needed to connect additional circuits for increased bandwidth. The client will be billed the standard monthly access fee for each port.
Clients must acquire and pay for their own T-1 or GigaMAN circuit. Clients are also responsible for acquiring and configuring routers, servers and other connectivity and computer equipment required for their sites.
ESC-20 will assist clients as needed to define the specifications for this equipment, purchase it through the clients own preferred vendors or the ESC-20 Technology Purchasing Co-op, and configure it for operation. Installation services are available through ESC-20 at an additional fee.
IP Address AllocationESC-20 will allocate IP addresses for the Client up to a maximum justifiable number as determined by the size of the network. Should the Client require a number of addresses beyond what can be provided by ESC-20, the Client must obtain the additional addresses directly from the American Registry for Internet Numbers (ARIN). In any case, the Client will be advised to conserve addresses by implementing a firewall, network address translation (NAT), or port address translation (PAT). These technologies are very effective in reducing public address space requirements while maintaining full capabilities and performance for the Client’s end users.
In the highly competitive world of telecommunications, stability is the most important factor in considering a service provider. Education Service Center, Region 20 (ESC-20) has selected Time Warner Cable San Antonio and Texas Education Telecommunications Network (TETN) as our Internet carriers. Currently, ESC-20 has a 200 Mbps redundant uplink to Time Warner Cable and 200 Mbps to TETN. ESC-20 employs Border Gateway Protocol (BGP) routing to achieve portability and autonomy. ESC-20 has an Autonomous System Number (ASN) which allows us to own and administer our Internet Protocol (IP) address space.
Time Warner Cable and TETN support ESC-20 with resources to negotiate telecommunication services and rates across service boundaries of local providers, providing a single point of contact for troubleshooting network failures, and guarantee the ability to scale capacity to meet bandwidth demand. Operating in the ESC-20 Data Center, the local Time Warner Cable point of presence and TETN interface directly with netVision20 to provide reliable, high performance Internet access to ESC-20 clients. The two (2) ISPs provide for added protection and redundancy.
During the hours of 8:00 a.m. through 5:00 p.m., Monday through Friday, except holidays, ESC-20 support staff will be available for telephone assistance regarding routers, DNS and systems related to Internet access.
